I've been a diesel mechanic for 30++++years. And i work for a school bus company at present time and these emissions on the new diesels are my nightmare!
My 2011 F350 opted to identify as a 1969 F100. I argued with him but he wanted the operation. So it no longer has a DPF between its wheels or an EGR under its bonnet. Since then he feels like a new man. Better fuel mileage, no black smoke, and can pull the Titanic off the ocean floor with a long enough chain. I’m glad he opted for this new lifestyle because it works well for me too.
What a great explanation. First time I’ve had the new emissions explained. Favorite quote, (paraphrased) “Sometimes the government fix is worse than the original problem”. Perfectly said.
@Lance Counihan Diesel emissions are far cleaner than gasoline emissions. The black smoke that comes out is actually MOSTLY oxygen. It's funny that just because it looks dirty, you think that it pollutes more than a gas motor. You're a sheep.
I'm with the group that thinks this was a very informative video. You did a good job of explaining what each new part does to a diesel engine and why the engineers really aren't coming up with any good solutions.
Why should an engineer have to come up with a solution? The entire concept of diesel exhaust emission controls was created and is pushed by the Chinese Communist party through means of propaganda, And it is an act of war with specific and malicious intent to destroy the economy of the United States. This is specifically how the Chinese Communist party is controlling our are entire transportation infrastructure, And they are using this as a plan to cripple nations. The Chinese Communist party controls 95 % of the supply supply of diesel exhaust fluid. The Chinese Communist party can Embargo a country, And prevent it from imports of the DEF, This act will stop most of the logistics and will stop agricultural production, Thus resulting in Civil War and starvation of a nation. Then of course the Chinese Communist party can then come in and take more control of the country.
His explanation of the DOC was very weak at best the DPF cannot operate without the chemical reaction taking place in the DOC. The DOC provides the heat to make a regen occur and thus cleaning the DPF until the soot load is to high and then you have to remove the DPF and have it cleaned
The politics are probably investors in all the different companies that are profiting off all the "safer and cleaner" changes going on in the industry.
Lots to learn in this. But, there are some misconceptions. I owned a 2012 Ford 6.7 that I drove stock until 38,000 miles. Then deleted. I also own a stock 2018 Ford 6.7. 1.) The reduction in fuel mileage during regeneration occurs infrequently. On my 6.7 Ford it's roughly every 500-600 miles. It regenerates for 12-24 miles depending on driving conditions. Otherwise, the engine is not using extra fuel to regenerate. 2.) I deleted a power stroke and put over 60,000 miles on it. I track every fill up with miles driven and fuel added. I gained less than 3/4 mpg overall. So, maybe there are folks who can take a snapshot of 100 miles driven at 55 mph on flat ground and see something significant....but show me the data...several thousand miles driven before and after delete with gallons consumed. And no, I am not one who hammers on vehicles. I am not saying a mpg increase can't happen....I am saying that when I go on websites about mpg and also look at my own results, there wasn't enough increase in fuel mileage to justify the cost of the delete. Check out Fuelly.com and my super duty seems to hit right in the average for other vehicles. 3.) The different strategies to raise the exhaust temperature CAN have an effect on engine oil....but so can an injector that fails open. I've put over 70,000 miles on non deleted 2012 and 2018 super duties and have every oil change sent for analysis. No oil dilution problems. Thus, the emission system is not negatively impacting the motor. 4.) Coking can occur with the EGR system, correct. I believe a lot of these issues have been mitigated with newer strategies. Early model diesels with the emissions systems suffered from myriad issues. Today's diesels have far fewer incidents. 5.) There is a real difference in what comes out the tailpipe. I am not a fan of black soot and while it may be a heavy particle, it does cause visible problems and health issues. Things I liked about my deleted truck: Whistle of turbo, peace of mind with knowing I wouldn't have sensor problems. Things I didn't like: exhaust smell, no warranty. Thanks for sharing the video and information. Your explanation of the exhaust components was great!
Sprinter owner, got 19mpg before and 25mpg after. Huge difference, probably depends on the make and model you own how much change you experience. Had constant sensor issues and dealer support was frankly underwhelming (9 reset and repair appointments in first three months of ownership, no ability to "fix" issues). Now, no sensor issues and no dealer support, so I feel that is basically a net improvement.
@@smittys19daytona I only deleted out of frustration with my short commute and "drive for filter cleaning" when I got home or to work. 2018 model and 2022 model haven't done that. Better strategy for regeneration I guess. Deleting for mileage is not going to make 99% of people happy. Yes...I've heard the people say they get 25 mpg. They own a unicorn or don't know how to do math.
I have an '04 duramax with a set of rebuilt Bosch injectors. The old ones started leaking fuel into the oil. With the rebuilt one my oil level stays dead on the full line now. My fuel mileage dropped from 12L/100 k miles to 14L/100 K miles. I was just looking at the average fuel consumption for a 2020 Silverado with a 6.6 and it's somewhere around 16L/100K miles. However the new trucks are bigger and have way more HP and Torque than my '04. I find it hard to believe you can get 30 to 50% better fuel mileage with a delete.
I'm more worried about longevity. When my warranty is up, I will probably delete it, so I can leave it idle when it's -20 degrees f out there. Plus all the soot going back in, ect.
Deleted my 2010 Ram 3500 one month after I bought it, 9 years later and 300,000 kms, best thing I ever did. Better fuel economy, more pulling power, no DPF issues. Full delete, but guess what, every 20,000 or so kms, a 'service exhaust system soon' message comes up on my dash. A timed message from the manufacturer no doubt so they can suck you into spending some more money at their shop. I have never brought my truck in for any emissions or exhaust work since it was deleted, so that is a scam for sure.
Reagan was shit. Fucker helped give immunity to judges, lawyers, and LEO's. Made it okay to lie -- as long as it was for a just cause. Gave illegals amnesty, AND helped big pharma. Fucker was the original version of Trump... yet people still drank his koolaid. Kids, anymore, do not research.
He also did this thing called, uh, Reaganomics I think, where he gave MASSIVE tax breaks to the wealthiest people and corporations while also deregulating the private and public sectors. This lead to the devaluation of the dollar and the start of wholesale job exportation to a lil place called Chiinaa. Ever heard of it? To cover the growing deficit created by the rich no longer paying their share of taxes Ronnie boy had to cut government spending. Just dumb stuff like public education for the children or public services. That lil quote you said was some real quality 1940s Germany type propaganda designed to dupe voters into paying more taxes for less empowerment for the populace that comes from governmental programs like small business loans, roads for commerce, and education for our children. Bet you ripped up your stimulus check tho! Just remember that quote the next time you hit a pothole or find lead in your tap water..

Should you delete? .. ABSOLUTELY. i spent hundreds and hundreds of dollars and a lot of down time trying to stay legal, before i said enough and did the smart thing. Wish i did it the day i bought the truck
Ellenor Malik I just paid $2,700 for a brand new SCR on a Sprinter. We’re getting screwed by the dealerships because they do not clean them. They make you buy new ones.
Ellenor Malik I know right! I’m ignorant to all this emissions stuff. After paying the damn money. I now start my research like a dummy. I guess I’m going for the delete option. This is my livelihood. I witnessed a friend cough up roughly 40k in 3yrs on a 2011 Sprinter. 90% of it do to emissions. Sprinters are made by Mercedes. You can imagine the invoices.
Great explanation of diesel emission controls. You are 100% correct that the cure is worse than the disease when it comes to engine emission controls. I have noticed the same with gasoline engines as well, although the gains from deleting the emission controls on a gas engine are nowhere near as significant as they are on diesel engines. I have long thought that the environment would be better served if regulators focused more on efficient combustion verses emission treatment. Great video. Well done.
The problem is that "more efficient" by the laws of physics entails stoichiometric combustion specifically because all else being equal the hotter the burn the more efficient the engine. But Nitrogen in the air ionizes well below that temperature, so an efficient engine by definition has nitrogen ions flying around during combustion, and nitrogen ions like to bond with oxygen, creating NOX. NOX is not that big of an issue if the burn is stoichiometric, like current petrol engines, because it is easily removed as long as the exhaust doesn't have significant oxygen remaining. But current diesels run lean, and so have oxygenated exhausts. And current diesel design sucks when running stoichiometrically. Since the combustion chamber walls are relatively cold combustion is quenched and you end up "rolling coal". So yes, the compression ignition engine needs a complete overhaul since the two types of emissions, NOX vs everything else, can't be easily handled at the same time without running stoichometrically, and soot forms near surfaces that are below ignition temperature. So yes, a complete redesign of compression ignition engines is required. They need to be replaced with hot wall ignition engines. This solves the soot problem while enabling stoichiometric combustion, which enables a cheap three-way cat to function.
I have a 09 6.6 Duramax 250,000 mi. The DPF is presently doing its regen now I seen this video and in the area I live in it doesn’t get its annual inspection , I do occasionally haul a car to racetracks with a gooseneck. I’m mostly interested in the mph and occasionally more torque, so interested in a delete, advise???
I saw you when you threw the marker and I drank the fluid before you told me not to. Besides these inconveniences, I appreciate your quality content. The corporations are trying to kill the Diesel engines, because these engines have a longer life, consume less, have more torque and are more efficient. Diesel is way less pollutant than many of the factories, pesticides on the crops, chemicals in our food and weapons testing. Maybe no more than petrol engines. I love Diesel.
He gets some things correct, but he doesn’t have a full understanding of how all these emissions systems work. I also like how he threw in his product placement at the end.
@@robertwoods532 I know this was 3 years ago you tell the audience what he missed all this crap is killing my state of California the report by heatran was the fake one has a fake PHD still works for California
tractorboy31 Yes because the government is the public enemy. It doesn’t care about public health issues. It just enjoys annoying people, car owner especially. [sarcasm]
“Gas mileage can be reduced up to 30% to 50%” any references to back this up? A normally functioning DPF will hardly effect mileage. A clogged DPF will reduce mileage dramatically. But a clogged DPF is symptom not a cause. If you have a DPF problem, check your MAF sensor, injectors, etc. I still have the original DPF on my car with 235k on it. And it still runs like when it was new.
If a deleted diesel gets 50% better mileage, it would appear half as much fuel would be used. Then you get into reduced pollution from diesel fuel production, transportation, storage, etc. It's screwy to have all this crap on an engine to reduce vehicle emissions at the cost of increasing fuel consumption, decreased engine life, increasing vehicle maintenance costs, reducing reliability, etc.
Hmmmm....I'm sure that no pollutants are created while manufacturing the emissions components or disposing of them after they fail either...you raise a great point but unfortunately not many people believe anything other than what they hear on cnn
@@JetSkiBuyFixPlaySellChannel , Not really, they make enough money off of the nominal cost of fuel consumed, plus even more money off of the manufacturing of plastics and other products made out of a barrel of oil.

Never did like the idea of an engine running on it's own waste, keep it old school well serviced and tuned keeps it easier for average people to own and maintain 🙂👍
One old timer back home in the 1970s drove his Farmall to the "beer garden" after a DUI.....got him around for a year. He's in his 80's and looks GREAT! Imbalming fluid. !
I gave you a thumbs up, as the presentation was excellent. One minor annoying point - substitute Fuel mileage for gas mileage. Just sounds wrong saying a diesel engine gets so much gas mileage.
Agreed 100% . Diesel enthusiasts lose credibility with me when they associate the word "gas" with a Diesel vehicle. This gent is obviously a smart guy and has likely forgotten more about Diesel engines than I will ever know, so why he's using such a Diesel layman's term is beyond me. My wife is by no means car savvy and I could be in for an expensive surprise if I used the word "gas" when referring to fueling either of our Diesel vehicles. I use terms like "fuel oil", or the "green handle" or just "Diesel fuel", never ever "gas". It's like referring to an internal combustion engine as a MOTOR. It's NOT a MOTOR as motors use electricity to do work, it's a heat ENGINE period. Words matter and yes, I am fun at parties.
I agree when I discuss mileage in my diesel trucks I refer to it as fuel economy. Also the DEF I buy is clear I think he said it was “blue like windshield washer fluid”. I agree with another comment that the best delete would be an EPA delete!
Recently had a DPF issue on my 2014 German performance SUV. Tried to regen with service mode or with high RPM on a highway and different additives with no effect. The cost replace DPF was around $5500, which is insane. Quoted $700 to $1k to clean, but no guarantee, it could fail in 6 months again. Also did an oil change and oil was very dark and thick, full of soot, making a huge wear on the engine. After a long research made a decision to do a delete and implement a Melone tune (ECU remap with delete) stage 2 on my TDI. It costed me $2100 for straight pipe, ECU remap and labor to put the pipes on. One of best decision I made. CEL went away, the truck got significantly more responsive, got plus 70hp, cut 1 sec on 0-60. MPG were improved by around 20% in city and 10% on a highway, giving me plus 50 to100 miles range on a tank. Got more range, power, torque, engine life and no headache over DPF/DEF. I am very happy with delete, highly recommend to diesel owners.
A very informative video. We get robbed here in Commiefornia with extortion gas and especially diesel prices due to the parasitic tax and spend politicians. Now that I have ascertained that this garbage DEF system not only reduces my mileage it also causes more engine failures and one has less power. I will look into getting my RAM def deleted.
Hell why don't ya try your luck with one of those junk pre 2014 engines that they made while trying to dodge paying royalties to fiat and see how you like them
My 7.3 ate a glow plug tip last week. It took out cylinder #7. It was well maintained and had 132k miles. I thought I was playing it safe with a nicer 7.3. No worries...until your engine blows up in the driveway due to a bad glow plug. Shit happens. Diesels are expensive. Dont buy a diesel unless you've got deep pockets.
Every diesel engine lover Should collaborate and file a massive class action lawsuit. Charging the EPA for every repair that their equipment has caused and future repairs or until they allow us to do whatever the hell we want to our own vehicles. That will get their attention hit them in the pocket.
Class action law suit sounds good. Hell, Monsanto has a class action law suit against them for glyphosate causing hodgkin's lymphoma. EPA is causing cancer to my 2014 Ram. Let's do it!
Cost me $5036 for new SCR on 2018 Ram this year in FEB that I currently drive, 2months later now come another engine light and dealer is wanting another $4k for bad driver (6 all together) for DEF Port, which they are saying it is making it fail ! Can you say delete
@@jottow680 and look at the mess CARB has made with this whole god damn thing. many commercial truck owners lost their ability to support themselves. way to go kalifornia
This video was the final answer I was looking for on whether or not to delete my 2012 Ram 2500. Best decision I ever made. It was like releasing a caged animal. It’s absolutely amazing how much the Diesel engine is restricted. The truck runs and towes better and looking forward to many great years to come from my truck. Thanks for this great educational video. Best one explained on UA-cam. 👍👍👍👍. Keep em coming. I’m subscribed. 👍👍
If you remember before all this EPA crap the engines were a lot smaller because they just didn’t need to be bigger to create enough torque to pull the Loads they are required to pull. So not only is the engine using more fuel to heat itself up, the engine itself is bigger than it needs to be to do the same job that used to do. The problem is that the diesel engine was too reliable and thats no good for the economy.. You used to see 30 year old diesels everywhere. Now they break before they’re paid off
@@jesseredfield8194 I just deleted and tuned my Diesel Sprinter van at 29K miles. It's out of basic warranty due to it's age (2018) NCV3 chassis made in Germany. I was getting maybe 15-16 mpg on average, now i'm getting 18-19 on average combo road/highway trips. Can't wait to get the van on the highway for an extended road trip. I do 65 mph normally so expect to see high 19's - 20 mpg rate. Wonderful for this highroof 4x4 sprinter which is like driving a brick through a wall at times.
Another serious possible effect caused by one of these systems happened to me. I had a 2007 Mazda 6 turbo diesel, which was fitted with a DPF. It was the first DPF equipped diesel that I had owned and I didn't understand how the system operated. I had owned the car for about two years and it was nearly due for its annual service. On my journey home from work one day, I was accelerating quite hard on a slip road, to join the motorway. On joining the motorway, I reduced pressure on the throttle, but instead of reducing speed, the car continued to accelerate - pretty violently! In my confused state, I pressed down on the clutch pedal and the tachometer needle tried to wrap itself around the stop - at which point I realised what was happening. What had happened, was the excess diesel fuel being injected into the engine, that was meant to force a regen of the catalist, had diluted the oil in the sump so much that it had raised the sump level to a point where it was being used by the engine as fuel. I was now dealing with a diesel runaway. I managed to control my speed with the brakes until the sump level had reduced enough to stop the runaway situation. To cut a long story short, the Mazda dealer didn't want to know, as I had been responsible for checking the oil level. They stated that the catalytic convertor was probably now 'junk', and would need to be replaced at a cost of about £2000... I will never buy another Diesel car.
Gary, I wouldn't be surprised if Diesels are soon outlawed in the U.K. I've read that France has already set a timetable for eliminating diesel powered vehicles. I don't know how this is going to square with the Trucking industry over there, or if it's even applicable to commercial trucks. But, knowing the Bleeding Heart Environmental movement, I suspect that it does.
When I lived out in CA, all vehicles had to pass the smog test. Now keep in mind, just waving the wand in the air would show fail, due to all the smog, but once that air went thru the engine, it would come out cleaner than when it went in. My 74 Dodge Dart, 225, would average about 12 mpg. My buddy's 74 Nova with the 250, averaged about 8 mpg with all the emission controls. Both were new vehicles. My buddy moved to Ohio, stripped the engine of all emissions stuff, and mileage went up to 24 mpg. I moved to IL and just traded mine in. I often wondered what an emission test would show with better mileage.
I think it's a complex issue, and there are disconnects at both end. The developers etc don't have the "boots on the ground" experience so make some dumb design errors Some people don't get the insane chemisty and other sciences behind the emmisions and what they do (partially due to the system, but also NOT EVERYONE HAS PHD's in organic chemistry) The solution is not youtube comments, or yelling, but people explaining the issue to the people who don't know. Also write your legislators in a thoughtful "so this is the issue" kind of way. Much better than ranting
great vid and excellent commentary. A great alternative to the straight pipe delete is cutting the DPF open, clearing of the dpf element, weld the shell back together and reinstall. From a cursory look, the DPF appears to be installed ... but it's just a giant section of exhaust pipe. Delete DEFINITELY extends engine life. Get a little throatier tone to your exhaust, too! :) BTW ... diesel trucks entering a hay field? Never happens right? The "genius" EPA goofballs ... yeah, put >1100 degree metal in contact/close prox to dry grass. what could POSSIBLY go wrong??? (interlocks? ... yeah, but that DPF won't cool as fast as that truck leaves the "high speed" surface to driving over winrows.) Perhaps they have a place in urban areas ... but not rural, yet they're even on TRACTORS. ugh.
I was in a parking lot and backed into a spot with my tailpipe next to a rosemary bush. It was very hot out and I was waiting for someone so I kept the truck running with the A/C on. After about 5 minutes I could smell this sweet smokey scent, reminded me of a stong smoked chicken. I got out of the truck to look around and noticed the rosemary bush smoking and on fire. I moved the truck and put out the fire. The fire was well contained in a parking lot however off road it could of been the start of a large wildfire.
Guess I'll delete, oh...7.3 nvm. In all seriousness- Im a farmer and we run tractors in idle as much as possible (throttle down, gear up) but emissions is brutal. If you haven't done enough high rpm the computer forces the engine to high throttle. For most applications this isn't any issue- except for spraying, where pto speed is related to volume and pressure output.
Pretty unreal isn’t it. I had this discussion with an acquaintance of mine that works for the epa. Friend or not he acknowledged this is simply done to “appear” as if they are doing something to help diesel admissions. He also told me they are fully aware they are actually putting MORE harmful chemicals into the atmosphere by requiring these products. The much higher quantity of fuel that is used to support these systems (and also the ammonia) ends up polluting more than it would if our diesels were left to run and breath on their own. It is simply an appearance for the liberals and tree huggers that throw a fit and really know absolutely nothing about what you just explained.
How are these systems putting more harmful chemicals into the air? I get that it seems like a terrible solution for engine longevity, but for what is coming out of the tailpipe, surely its better with the dpf and Scr systems.
@@JeLifeCoach It’s not that it creates more coming out of the devices. It’s the long term affects. You burn much more fuel to do it (which is the huge one) so it’s a null and void point. You have to think long term, not what is actually coming out of the tailpipe. Manufacturing (energy) of these components, disposal of these components, they contain harmful products, etc, etc. Yes, what’s actually coming out of the tailpipe is “cleaner” but at what cost? Plus it’s marginally cleaner. If a diesel is running properly and fueled properly the emissions are extremely low and non toxic. Plus, they the majority actually fall to the ground, not pollute the air. It’s all these assholes that don’t know how to tune a diesel and just add fuel. Had they not done all that bullshit with their black smoke, it would have never been an issue. I’ve built many Diesel engines and they are capable of a ton of power without the smoke. And actually are quite economical for the power produced. Nobody thinks of everything going on behind the scenes and downstream…..only that there is a sticker for the world to see that reads “certified clean idle.”
@@specforged5651 I first want to say thank you for your reply. I am new to all of this and I dont know anything. All I know is I care about the environment, I recycle, try to be as conscious as possible, and I own a diesel station wagon that gets 43mpg to run my mobile detailing business. I just want my car to last over 300K miles, help others, and help the planet. I would love to learn more from you. My smog rating and emission rating per my window sticker is considerably lower that gas powder vehicles of the same generation so I know these systems work form the tailpipe as you’ve stated. What should I do?
@@JeLifeCoach There are very very few who actually want to harm the planet. We are not out to destroy the environment by driving large diesel trucks and wanting to enjoy our hobby’s such as building engines and racing. It’s very similar to the two stroke four stroke argument. Funny how California “outlawed” two strokes except for “closed course competition” which is a huge portion of two stroke engines. Two strokes are bow making a huge come back in that world btw. The problem is they want their cake and want to eat it too. They want it both ways and that just isn’t a reality. The entire leftist and save the environment crowd always wants it both ways. In fact they want it every way imaginable. So their suggestion…go buy a Tesla right? And how do you think that Tesla is manufactured? By energy from windmills and Nancy Pelosi’s farts (prob could actually)? No! It’s manufactured in facilities that burn fossil fuels for energy and use extremely harmful materials in those batteries that have a very short lifespan. Then are what? You guessed it, trashed into the environment. And what are the vast majority of cars manufactured out of? Yep, plastic…..better known as petroleum products. And where does the energy to charge those batteries every 50 miles come from? Those same Pelosi farts and solar panels? Nope, the burning of fossil fuels. They act like they are the saviors of the world when in the long run they are many times making it worse. It’s ALL for show. I have zero problems putting emission helping devices on my truck if they actually are for the right reasons and actually do what they claim in the long run. It is all about the sake of them feeling better about themselves in the moment and to their extreme followers. Good news is most people are seeing through it and it won’t last much longer. They’ve dug their own grave and they’re about to lie in it because it’s all based on a lie and an “idea”, not scientific evidence, logic and realistic behaviors. My suggestion to you is stuck with your diesel, change the oil often, don’t let it idle and cross your fingers it will last that long. Because if it was built after 2007 with all of this ridiculous emissions crap on it, it will absolutely not. I have a 1994 12V Cummins truck I keep at my cabin that has 417,000 miles in it, blows a very very small amount of black smoke and gets 26 mpg. So you tell me what’s harming the environment worse. My new truck that gets 14mpg and has to be replaced 3 times as often, thus using more fossil fuels for energy in manufacturing, more petroleum products for all the plastic and about every other material made. Not to mention the harmful materials used in the manufacturing of the actual emissions devices. Which include heavy and toxic metals and materials. Or that old truck that has been around for 25years, gets the oil changed 1/4 as often and uses a 1/3 of the fuel. You do know how these DPF devices clear themselves of soot right? They inject a large amount of diesel straight into the exhaust to burn it off, thus producing a tremendous amount of pollutants (NOX) they are suppose to be filtering out? There is zero logic and realism behind it. Good luck my friend, keep up on the maintenance of that little diesel and I hope it serves you well. Plus a diesel station wagon!? Hell ya!
@@JeLifeCoach Oh and if your little diesel uses DEF. Put high grade DEF in it. Not the cheapest shit you can buy and definitely not the garbage at the pumps. It will save you down the road with def heaters, tanks, pumps and control equipment. That crap will ruin all those devices.
I deleted my diesel and yes what this man I saying is very true. Very costly to do. I’ve never been happier w my diesel tho. I’ve increased my hp more then 50 % straight piped it and now that Turbo whistles. My Egr was fool of soot and took power away. I had a professional Program and Tune the motor and Trans post delete. I think it’s a good investment for your pickup and firmly stand by deleting.
I deleted all that crap from my '08 Ford and it runs so much better and used so much less fuel. Highly recommended. People would be shocked at the cumulative carbon footprint of all the DPFs in the commercial fleet.
Does your car blow black smoke after the delete? I am thinking of removing mine but worried if it will blow too much smoke and attract too much unwanted attention.
Uh.... on my friends 2018 ram that is deleted we found that if the turner does a good job it still burns extremely clean. It can be ran on its highest setting +200hp and you can only get any smoke at low boost which with the newer turbos isn’t for very long. Biggest thing I noticed is that the stock turbo went from running 26psi max boost to 39psi max boost. That for obvious reason adds a lot of power. Didn’t notice any increase in fuel mileage however didn’t see a decrease which was surprising considering how much more fuel is added to go along with the extra 13 pounds of boost. So far so good. Unloaded probably 500# worth of crap off the truck and dropped the egt considerably. That’s all due to the huge reduction in the exhaust back pressure. This is his 6th deleted ram and will do it again. This one was deleted at 140 miles and it was amazing how much build up was already in the egr cross over tube. Also another thing to consider is how extremely corrosive def is. It’s literally liquid urea which is used as a nitrogen fertilizer on farms across the United States. Great vid. Thanks.
@@larryarmstrong6973 , The speed limit in California for towing vehicles is 55 mph. I run at 60 when towing with my 7.3. I let it wind up to speed slowly and take my foot off the accelerator at shift points to make it easier on the automatic trans. Once its in high gear (overdrive off) I mash the pedal to the floor if need be to take a hill. What's the hurry? Are you worried about offending the impatient people in cars behind you perhaps? The cost of owning a 6.7 is too high unless you have money to burn. If I was to buy a new truck today, I'd get the gas 7.3.
I did my delete after ram said my new turbo would cost me $3500 to replace at 38k miles! the cause was 1100 to 1200 EGT's . sent it out to a rebuilder for $800, cost of delete $800, so for $1600 its fixed for good. now It wont reach 1000 EGT on big hills hills towing 20k lbs. the black soot is no longer being sucked into my motor making it very happy and I have more MPG and much better power with no smoke. I left the stock muffler on so its not noisy but it has a sweet rumble now that makes me smile all day.
Even with soot being heavier and settling to the ground more quickly than other particulate matter, it doesn't dissipate fast enough in most cases to not have an effect on the environment in two major cases: 1. Highway driving. Many times I've driven behind heavy duty trucks (dump trucks, cement trucks, etc) or light duty pickups. Not always, but not uncommonly either, I am behind one that likely has had some sort of exhaust system modification, and lots of soot/smoke is blowing out of the tailpipe, or upright stacks. I'm effectively driving within a smoke screen of haze and fumes that at the very least dirties my car, and at the worst, is pulled in through the hvac system into the cabin where I'm breathing air. The only option is to speed, and pass the offending driver to get back to driving in cleaner air. In my opinion, it's incredibly obnoxious and really unpleasant to just be stuck behind a, for lack of a better word, smelly truck. In this case, the soot cannot fall to the ground fast enough as I'm about 1 second of driving distance from the truck. 2. City/urban environments. Walking along a sidewalk in a city, and finding yourself next to a truck that has exhaust modifications mentioned above, you'll find yourself walking through a cloud of soot or fumes. Again, sure the soot is heavy, but if I'm walking down the sidewalk and a truck accelerate from a light and goes past me, it leaves me and other pedestrians in a cloud of unhealthy fumes. The soot doesn't fall to the ground fast enough before me and others are forced to inhale it because there's no clean air around for the next 20 seconds or so until a fresh gust of wind dissipates it. People will probably say my comment is gay or something stupid but I'm just being real. The "heavy soot" excuse is one that drives me nuts. Yes it's obviously heavier and will fall to the ground but that doesn't mean everything is all well and good. Thanks for the video, watched this because I'm curious about buying a Jeep Ecodiesel and have seen the emissions systems can be pretty maintenance intensive on them.
Very well written. I’m all for maximum freedom and upholding the constitution in terms of maintaining states rights, the issues you mention could be addressed better by local and state governments instead of the EPA whose authority is too far overreaching. In simple words yea it would suck if an emission deleted diesel truck drove by a downtown shopping street filled with pedestrians enjoying their weekend with family.
If any car or truck is emitting black smoke out of their tailpipes there are mechanical issues. A normal tune doesn't allow that. it's these idiots that think "rolling coal" is cool, that drives me nuts. They're the ones that are ruining it for everyone. I have the 3rd gen ram ecodiesel and it's a wonderful engine. Highly recommend it
This was really interesting. What I have not seen is reasonable effective emmissions control measures. It's a little like if someone had an amputation deciding the solution is to cut off the good leg to make it the same length. Carbon emmessions can be cleaned up through proper tunning and a catalytic convereter to completely the cumbustion reaction. The NOx issue is better handled by reducing or emoving N from or again by introducing H to the combustion cycle either trough direct injection of H2 gas into the combustion chamber or catalytic converter or with NH4. The biggest change would be oil companies pre treating diesel fuels with solvents to completely remove Sulphur and nitrous compounds in the fuel. Biodiesel blends can substantially reduce NOx and SOx emissions. So I say get on the case of fuel producers to develop a sustainable product, not the individual auto producer or auto owner.
True enough, as many people piss and moan about biofuels taking away all the food from everyone but they wanna bulldoze every single strip of farmland in sight to build subdivisions
Diesel injectors and fuel pumps are lubricated by the sulfur in diesel fuel. If they remove sulfur they will have to put something else in its place to keep the lubricity. In fact modern "low sulfur" diesel fuel doesn't lube nearly as good as it he old stuff. So now you have people who own older diesels pouring 2 stroke oil into their fuel to help lubricate the injection pumps.
perashmura I was at the local dealership when a guy came in with a late model deleted pickup he wanted to trade in, the dealership told him the truck was worthless to them, warranty VOID and they can’t sell deleted vehicles. Private buyers should also beware of deleted vehicles, you’ll be stuck with them unless you find another private party to sell to.
Wow! You should teach a course on this! I pull a 10,000 lbs. gooseneck horse trailer, and am trying to decide if I should trade in the 6.0L gasser for a diesel for better fuel economy and longer engine life. Your video supports previous advice to buy a gasser if I want a 2010 or newer truck. I've read there can be stiff fines and penalties in every state for driving a deleted diesel truck on roads.
The CEO of RAM once stated the 6.7 technically runs clean and doesnt need any of this BS and the only reason it has the Egr is because the government said so. True?
@@cynicaltexan9639 an exaggeration to point out that whatever gets you compliant with EPA requirements is what matters. With current technology there's no way that can be done without EGR, or you can bet it would be gone.
When the Cummins 6.7 first came out in the Ram, it did not need DEF/SCR to be compliant but it did have EGR and DPF. Later on DEF/SCR was added to the 6.7 when regulations got tighter
@@creigmacc EGR does the same thing SCR injection does but EGR shortens engine and oil life and increases load on the cooling system. It is an extremely outdated way of reducing emissions. You could go DPF/SCR only and meet emissions but that would increase SCR usage and people already hate having to fill it with current usage rates.
Great video on how this all works. Both my daily driver and hotshot truck uses the 7.3 Powerstroke which thankfully has nothing to delete. I am planning on buying a semi soon and already knew I wanted a pre DEF truck and will buy one that is pre 2000 if possible. There is a tradeoff between comfort in the cab and engine performance / reliability. I think I will choose to be more comfortable when I retire and not worry about it while I'm driving.
If you can get a N14 power plant one of the best engines ever made I worked at a KW dealership for 25 years and can still count on 1 hand how many I overhauled they do have a few problems but nothing major unlike Cat or Detroit
@@davidsignor7931 I wound up buying a 2010 Peterbilt 387 with an ISX-15 (CM-871). Dealer said it was a 10 speed... guess they didn't know what the little red lever on the shifter was for. Turned out to be a 13 speed. I wasn't mad... makes it better for hauling heavy flatbed loads!
I want to delete my 17 Powerstroke but after 41k miles it’s been an amazingly reliable and dependable truck. I have an extended warranty from Ford, dealer sucked big time and the GM purchased it as part of the deal, to 100K miles. So I think I’ll wait till then to delete it since I’d have to clean or replace the DPF at 125k.
Deleted EGR cooler, valve and all the exhaust crap on my 2011 Ram. Used PPEI system including tuner. Runs soooo much better and no coal out the back. Easy to do and would highly recommend it!!!!
Anything that reduces the fuel consumption per horsepower hour is ultimately a reduction in emissions. When I delete, the first thing to go, is the EGR. I think you can avoid deleting the DPF and SCR by driving with gradual movement on the accelerator, giving the turbo time to spin up as you need more power. That prevents "rolling coal", because of the sudden increase of fuel, before the turbo has time to spool up to boost. Smooth easy transitions in throttle will allow the computer and turbo to adapt to the new demand. Less particulates, less need to regenerate the DPF, and maintaining the SCR. I've never owned a GM diesel equipped with a SCR. How much DEF does it use per 20 gallons of diesel fuel? How expensive is it? Do you just add each time you fuel up?
Very informative, I thought the SCR took the place of the DPF, didn't realise the most recent diesels still had both. And "diesel exhaust fluid" is called "AdBlue" here in the UK
@@wizard_of_poz4413 Would there be a benefit from deleting my EGR but keeping my dpf and Scr. I care about the environment and my engine!!!! What do I do?
We have 2 very unreliable 2012 duramax. Deleting def and part. Filter was the only option for reliable operation. Cost 900 each. Trucks have run over a year without fault.
Ha, same thing for my buddies Duramax, It was a absolute turd when he got it. Now that he deleted the EGR its running smooth as butter and spends time in the garage instead of at the dealership
Wow! Thank you. That was the most helpful video I’ve seen. My brain is wired to find out the how’s and why’s. And you nailed it. Now I guess I need to look over my warranty and start saving my pennies. As soon as it’s safe to do some deletes, it’s done.
I had 2 major issues with my 2017 RAM 3500 (1 contamination and a sensor failure with ghost code in the computer). Both had me down for weeks and could not rely on the truck for long haul anymore. So a DELETE is scheduled as my x-mas gift! I hope this will solve all the previous problems because the truck is flawless otherwise. Thanks for the great info, well appreciated.
@@jesseredfield8194 it's been almost 2 years and the power gain is amazing. I'm not talking about fuel economy because it's amazing also! No issues with nothing yet.
@@conypard4441 i appreciate the info. I have a cdl, wont use the truck for commercial purposes but im afraid to get popped for that they’d really put the screws to me lol but have you had to take it in for service? Like dodge doesn’t notice?
@@conypard4441 thanks for the note Cony, I'm post delete on my 2018 Sprinter 4x4 - no problems and runs much better now. I'm in Florida so no emissions here. This van has been on my radar for 50 years at least, known reliability and longevity - then epa IMHO ruined them. I hope to keep this van for the rest of my days (im 70) it's had 3 oil changes in it's 29K age and getting ready to do another shortly. I also changed my gear oil recently to better AMSOIL grade. Run synthetic oil always, started with Redline full synthetic but changed over to Amsoil - all is well in vanland. from Brunhilda ...oh yes, I added a air/oil seperator to the system also which helps prevent oil mist getting to the air intake.
The current regulations are pitiful. 50% less mileage (which = more fuel cost), 30% less power ( which causes more fuel use and fuel cost), etc, etc, etc………… doubling fuel costs just doesnt seem to bother the government, while at the same time actually causing more emissions. The h3ll is this country coming to?
@@sharonsybrandt2249 That dumb bitch is merely being used as a false front to further the man made global warming hoax. No chemistry or science involved here. Just emotions from a clueless brat who doesn't know she is being exploited.
Super funny thing was when they started the DEF diesel pickups. In Canada, the DEF fluids would freeze and leave guys stranded. So DEF delete became very common. Then GM put their DEF fluid tanks underneath the passenger side front seat. Then guys drove on logging and oilfield roads (very poor) and bottom out and break those tanks. So DEF Delete was MANDATORY.
The new control devices make the engine wear out faster, so you must by a new engine sooner :: handy for the motor trade. At my age, sometimes I get nostalgic for the full old-type diesel exhaust smell.
@@lordoftherims436 I remember the old proper full diesel brrrrm noise. I read once a truck driver complaining that all the junk that he must put in his diesel exhaust stream is cutting down his engine's power: " _Let our diesels breath freely_ !".
Deleted dpf on my 09 Cummins increased mileage from 14 to 20 plus I get 14 towing a heavy trailer now when I got 9 before it’s a tremendous mileage boost to delete
As a H,D Mechanic I work on these systems weekly. All of our oil is tested at every service we don't get diesel dilution without a bad injector, bad quill tubes or bad injector lines if run under the valve cover. Re burn systems do not cause diesel dilution in the oil unless the system has failed.
I have never understood the logic on this either. Burn more fuel to "reduce" emissions. In over the road trucks the numbers are staggering. As far as soot, with today's electronic injection, there is no reason why a deleted truck that is tuned properly should make soot. But I digress. All this emissions hardware runs up the initial cost of the vehicle, is marginally reliable at best, and, as mentioned, actually causes more fuel to be consumed. Government logic at its best. I am left to conclude that they actually have all the regulations surrounding diesels in place so that owning one becomes less attractive. Why? If diesels caught on and vehicles routinely got 30-40+ mpg, people would buy them in droves and the ultimate demise of the internal combustion engine would be postponed. Yes, I think the Left and the government ultimately are so rabid about the theory of man made climate change that one of their goals is the demise of fossil fuel use. One way to do that is to make efficient fossil fuel engines unreliable and impractically expensive.
I'm no tree hugger but there are cities with high levels of toxicity in the air and NoX is part of the problem. I don't judge a guy that deletes but there is definitely a reason why these measures were put into place. A guy driving through the country with no filtration/treatment on his/her diesel truck is different than 1,000 busses idling in a cramped city with thousands of of people filling the sidewalks around them.
I can guarantee you that if the EPA/CARB was paying for the extra fuel used, 30 to 50%, to run a DPF and EGR, they would find a different system to control emissions. But, since the public is the one who pays double in fuel consumption to produce "less emissions", they don't care about that even though they are the same entity who mandates and tells auto manufactures to increase their fuel efficiency. Imagine that, the EPA allowing less MPG on diesels all while they are mandating more MPG ! This concern reminds me of the 1970's when engine compression went from 11:1 down to 8.5:1, EGR was invented and then catalytic converters that smelled like rotten eggs. MPG went from 18 to 22 MPG down to 8 to 10 MPG and folks had overheating vehicles in masses.

Wow! thank you so much for all of the great information. This has helped me greatly with making truck purchase decisions based on the best fuel economy after deleting.
Here in Oregon they're trying to pass cap and trade, under these proposed bills, they aim to remove diesel POV's older than 2010...among other things of course.
@@leethomas556 Time to move. I've been saying that for the last 5 years since the fires have gotten so bad. Serious about it now. I don't want to pay for a new vehicle. CA has already done this, BTW. I have a horse friend who has a small business and they wouldn't renew his 5 diesel truck registrations because they are older than 2010. Put him out of business.
I love the emissions controls because it’s so clean and no high carcinogenic into the lung. Luckily I have a third generation eco-diesel from my 2023 gladiator. They fixed a lot of the issues on this engine. One of the biggest things is you get the EGR after the DPF so it’s quite clean now. Do 4000 mile oil change. I run 85+ redline additive in the tank as well.
I don’t want to be disrespectful but you are misleading on some of your information. There’s not a muffler on these newer Diesel engines. The aftertreatment system muffles the exhaust enough to where you don’t need a muffler. The engine produces NOx, Soot/Hydrocarbon (HC) and also burns oil. Every engine burns a little oil although most can not be recognized. The DOC is used with the DPF. It’s not separate, it’s mounted right in front of the DPF. The DOC does nothing but creates heat in the exhaust. There are 3 fault codes associated with this and they are 2639, 1921, 1922. You’re talking about a stationary regen and it only happens when you idle a heck of a lot or if you have excessive oil consumption plugging up the DPF. Post injection occurs when the injectors inject fuel during the exhaust stroke. Now speaking with just Cummins engines for a bit. The aftertreatment injector was used on heavy-duty engines (M11, ISX12, ISX15) and goes behind the turbo and inlet NOx sensor but this method is not used anymore on their heavy-duty engine products that are 2017 and newer, they all use post injection now. Anyways, this fuel reacts with the platinum within the DOC raising its temperature around 343°C (650°F) and this is hot enough to atomize the soot within the DPF. The soot in the DPF creates heat when it atomizes raising the temperature around 565°C (1050°F). If the temperatures get above 593°C then it starts the melt the substrate within the DPF. The ash does not get atomized. It stays in the filter and is what gets cleaned out when the filter gets cleaned. Ash is additives from the oil. Post injection does not wash the cylinder walls or dilute the oil. It’s not even a full injection. It’s just a quick small injection, doesn’t affect fuel mileage any. Soot is not heavier than air. Smog? California? Soot is hydrocarbons and this along with NOx can mix with moisture in the air producing acid rain. SCR stands for Selective Catalyst Reduction. DEF is a 32.5% mixture of synthetic urea and the rest is deionized water. It’s made to freeze and once it thaws it goes back to the 32.5% mixture. Age does not make the DEF crystallize but DEF does degrade overtime. The shelf life is two years. The computer looks at the inlet NOx sensor and outlet NOx sensor to determine how much DEF is needed to inject. Once DEF is injected, the water atomizes from the high temperatures and you’re left with the urea. This reacts with amox brick and scr bricks within the SCR converting the NOx and HC into CO2, H2O, and N2. The SCR is a full flow pass through device which is very hard to plug with soot. If there is an excessive amount of ammonia coming out of the exhaust a fault code with be logged. On Cummins it’s a 3582 or Selective Catalyst Reduction Conversion Efficiency. These engines are designed and built with these components in mind. It’s done to be able to sell engine within the North American market. It’s not something Cummins, Detroit Diesel, PACCAR, Powerstroke, Duramax or any other engine company wants to put on their engines for on-highway use. Off-highway is a completely different discussion with their Teir 4 Final emissions. Euro emissions is a completely different discussion with Euro-6 emissions. It was great content just some was misleading.
It's the N0S that's the issue. I wouldn't have a newer one without DEF. The prior choked ones ate fuel and clogged the EGR. DEF allowed the engineers to detune the emissions somewhat. Different brand but my friend maintains four F-550's with DEF and none have had an issue in over 100K of abuse. If the election goes the way of the Dems,the war on diesel will escalate exponentially. I'll keep my '07 5.9 with internal EGR.
@@abramspearman9046 Boy it's been explained on the TDR site but I can't recall Guy's will install aftermarket cams that correct the issue. Oil stays a bit cleaner but they saw minimal increase in mpg. I know a guy who scooped up a 2003 qcsb 3500 manual from Arizona. 5.9 HO. In California the federal vehicles must have 7500+ miles in order to be registered here. He kept it for years and I asked him how it was doing. "Oh I sold it and now I have a 2007.5 6.7." Geez. There's the same truck up the street that sits. The dad bought it from his son. The son had pulled a Toyhauler -type trailer to Honduras and back with it . Toyo MT's never failed and the truck never missed a beat on 3rd world diesel.
You explained this very well . Most people don't know the reasons to do this other than the Horse Power reason. My truck actually runs smoother and like I said way better gas mileage . I get 27mpg on expressway in the winter gas and 30mpg on summer gas with HotShot Diesel additive .
I used to live in Michigan and in the winter they add stuff to the diesel fuel so it doesn't gel up from the cold and it makes you get worse gas mileage.
I have a small fleet of diesels, prior to deleting them all I’d need to always have a spare truck available because of emissions breakdowns. Our government needs to take a serious look at diesel emissions garbage, this crap isn’t the answer!

The doc is an important part of the diesel fuel chemical reaction needed to increase EGTs to burn off particulate matter caught in the substrates in the dpf and decrease nox. Other than that great simplified demonstration. I have wondered though if you delete the egr cooler do you lose any air mass. Probably not a lot as long as the tune makes up for it with the VGT on the turbo. but what if you don't put a delete tune and just plate off the egr cooler like so many 6.0 owners do and just deal with the CEL for egr insufficient flow. Is there less air flow than normally requested? And could drilling a hole in the egr passage way in the intake with an air filter be a good way to bring back that air flow and replacing the dirty egr gases with clean air and taking the CEL away? Might try it on my 6.0 and let you know on a dyno if there were any differences. - Seth Mazza from va

I've been a diesel mechanic for 30++++years. And i work for a school bus company at present time and these emissions on the new diesels are my nightmare!
My 2011 F350 opted to identify as a 1969 F100. I argued with him but he wanted the operation. So it no longer has a DPF between its wheels or an EGR under its bonnet. Since then he feels like a new man. Better fuel mileage, no black smoke, and can pull the Titanic off the ocean floor with a long enough chain. I’m glad he opted for this new lifestyle because it works well for me too.
@Lucas Clark... neither. It just identifies as such.
What a great explanation. First time I’ve had the new emissions explained. Favorite quote, (paraphrased) “Sometimes the government fix is worse than the original problem”. Perfectly said.

I'm with the group that thinks this was a very informative video. You did a good job of explaining what each new part does to a diesel engine and why the engineers really aren't coming up with any good solutions.
Why should an engineer have to come up with a solution? The entire concept of diesel exhaust emission controls was created and is pushed by the Chinese Communist party through means of propaganda, And it is an act of war with specific and malicious intent to destroy the economy of the United States. This is specifically how the Chinese Communist party is controlling our are entire transportation infrastructure, And they are using this as a plan to cripple nations. The Chinese Communist party controls 95 % of the supply supply of diesel exhaust fluid. The Chinese Communist party can Embargo a country, And prevent it from imports of the DEF, This act will stop most of the logistics and will stop agricultural production, Thus resulting in Civil War and starvation of a nation. Then of course the Chinese Communist party can then come in and take more control of the country.
Thank you so much. Great explanation on deletes. Ive been on the fence but now convinced to get the delete.
Well there is not much extra they can do without it being electric 🤣
His explanation of the DOC was very weak at best the DPF cannot operate without the chemical reaction taking place in the DOC. The DOC provides the heat to make a regen occur and thus cleaning the DPF until the soot load is to high and then you have to remove the DPF and have it cleaned

Lots to learn in this. But, there are some misconceptions. I owned a 2012 Ford 6.7 that I drove stock until 38,000 miles. Then deleted. I also own a stock 2018 Ford 6.7.
1.) The reduction in fuel mileage during regeneration occurs infrequently. On my 6.7 Ford it's roughly every 500-600 miles. It regenerates for 12-24 miles depending on driving conditions. Otherwise, the engine is not using extra fuel to regenerate.
2.) I deleted a power stroke and put over 60,000 miles on it. I track every fill up with miles driven and fuel added. I gained less than 3/4 mpg overall. So, maybe there are folks who can take a snapshot of 100 miles driven at 55 mph on flat ground and see something significant....but show me the data...several thousand miles driven before and after delete with gallons consumed. And no, I am not one who hammers on vehicles. I am not saying a mpg increase can't happen....I am saying that when I go on websites about mpg and also look at my own results, there wasn't enough increase in fuel mileage to justify the cost of the delete. Check out Fuelly.com and my super duty seems to hit right in the average for other vehicles.
3.) The different strategies to raise the exhaust temperature CAN have an effect on engine oil....but so can an injector that fails open. I've put over 70,000 miles on non deleted 2012 and 2018 super duties and have every oil change sent for analysis. No oil dilution problems. Thus, the emission system is not negatively impacting the motor.
4.) Coking can occur with the EGR system, correct. I believe a lot of these issues have been mitigated with newer strategies. Early model diesels with the emissions systems suffered from myriad issues. Today's diesels have far fewer incidents.
5.) There is a real difference in what comes out the tailpipe. I am not a fan of black soot and while it may be a heavy particle, it does cause visible problems and health issues.
Things I liked about my deleted truck: Whistle of turbo, peace of mind with knowing I wouldn't have sensor problems. Things I didn't like: exhaust smell, no warranty.
Thanks for sharing the video and information. Your explanation of the exhaust components was great!
Sprinter owner, got 19mpg before and 25mpg after. Huge difference, probably depends on the make and model you own how much change you experience. Had constant sensor issues and dealer support was frankly underwhelming (9 reset and repair appointments in first three months of ownership, no ability to "fix" issues). Now, no sensor issues and no dealer support, so I feel that is basically a net improvement.
My HVAC guy said the exact thing about his 6.7 virtually no increase in mileage, still on the fence with my dmax
@@smittys19daytona I only deleted out of frustration with my short commute and "drive for filter cleaning" when I got home or to work. 2018 model and 2022 model haven't done that. Better strategy for regeneration I guess. Deleting for mileage is not going to make 99% of people happy.
Yes...I've heard the people say they get 25 mpg. They own a unicorn or don't know how to do math.
I have an '04 duramax with a set of rebuilt Bosch injectors. The old ones started leaking fuel into the oil. With the rebuilt one my oil level stays dead on the full line now. My fuel mileage dropped from 12L/100 k miles to 14L/100 K miles. I was just looking at the average fuel consumption for a 2020 Silverado with a 6.6 and it's somewhere around 16L/100K miles. However the new trucks are bigger and have way more HP and Torque than my '04. I find it hard to believe you can get 30 to 50% better fuel mileage with a delete.
I'm more worried about longevity. When my warranty is up, I will probably delete it, so I can leave it idle when it's -20 degrees f out there. Plus all the soot going back in, ect.
I'm disappointed you only have two videos. Please film some more. You're actually one of the most knowledgeable people on UA-cam talking about diesel

Full delete, but guess what, every 20,000 or so kms, a 'service exhaust system soon' message comes up on my dash. A timed message from the manufacturer no doubt so they can suck you into spending some more money at their shop. I have never brought my truck in for any emissions or exhaust work since it was deleted, so that is a scam for sure.
I knew most of this but you did a really good job explaining it. A picture is worth a 1000 words.

Ronald Reagan once said “the scariest thing to ever hear is I’m from the government and I’m here to help”
And he was the head of the government for 8 years! Reagan run for government office to scare people and not help them!
Reagan was shit. Fucker helped give immunity to judges, lawyers, and LEO's. Made it okay to lie -- as long as it was for a just cause. Gave illegals amnesty, AND helped big pharma. Fucker was the original version of Trump... yet people still drank his koolaid. Kids, anymore, do not research.
He also did this thing called, uh, Reaganomics I think, where he gave MASSIVE tax breaks to the wealthiest people and corporations while also deregulating the private and public sectors. This lead to the devaluation of the dollar and the start of wholesale job exportation to a lil place called Chiinaa. Ever heard of it?
To cover the growing deficit created by the rich no longer paying their share of taxes Ronnie boy had to cut government spending. Just dumb stuff like public education for the children or public services.
That lil quote you said was some real quality 1940s Germany type propaganda designed to dupe voters into paying more taxes for less empowerment for the populace that comes from governmental programs like small business loans, roads for commerce, and education for our children.
Bet you ripped up your stimulus check tho!
Just remember that quote the next time you hit a pothole or find lead in your tap water..

EGR is why we need DPF. They could have just done SCR.
Ellenor Malik I just paid $2,700 for a brand new SCR on a Sprinter. We’re getting screwed by the dealerships because they do not clean them. They make you buy new ones.
@@eddilovee A racket if I ever saw one.
Ellenor Malik I know right! I’m ignorant to all this emissions stuff. After paying the damn money. I now start my research like a dummy. I guess I’m going for the delete option. This is my livelihood. I witnessed a friend cough up roughly 40k in 3yrs on a 2011 Sprinter. 90% of it do to emissions. Sprinters are made by Mercedes. You can imagine the invoices.
Great explanation of diesel emission controls. You are 100% correct that the cure is worse than the disease when it comes to engine emission controls. I have noticed the same with gasoline engines as well, although the gains from deleting the emission controls on a gas engine are nowhere near as significant as they are on diesel engines. I have long thought that the environment would be better served if regulators focused more on efficient combustion verses emission treatment. Great video. Well done.
Just like a pill pushing doctor. Keep treating the symptoms because finding the cure won't make money.
I absolutely agree. More efficient engines are truly the answer.
The problem is that "more efficient" by the laws of physics entails stoichiometric combustion specifically because all else being equal the hotter the burn the more efficient the engine. But Nitrogen in the air ionizes well below that temperature, so an efficient engine by definition has nitrogen ions flying around during combustion, and nitrogen ions like to bond with oxygen, creating NOX.
NOX is not that big of an issue if the burn is stoichiometric, like current petrol engines, because it is easily removed as long as the exhaust doesn't have significant oxygen remaining. But current diesels run lean, and so have oxygenated exhausts.
And current diesel design sucks when running stoichiometrically. Since the combustion chamber walls are relatively cold combustion is quenched and you end up "rolling coal". So yes, the compression ignition engine needs a complete overhaul since the two types of emissions, NOX vs everything else, can't be easily handled at the same time without running stoichometrically, and soot forms near surfaces that are below ignition temperature.
So yes, a complete redesign of compression ignition engines is required. They need to be replaced with hot wall ignition engines. This solves the soot problem while enabling stoichiometric combustion, which enables a cheap three-way cat to function.
I have a 09 6.6 Duramax 250,000 mi. The DPF is presently doing its regen now I seen this video and in the area I live in it doesn’t get its annual inspection , I do occasionally haul a car to racetracks with a gooseneck. I’m mostly interested in the mph and occasionally more torque, so interested in a delete, advise???
Combustion has been just about perfect for decades. But perfect, 100% combustion makes pollution.
I saw you when you threw the marker and I drank the fluid before you told me not to. Besides these inconveniences, I appreciate your quality content. The corporations are trying to kill the Diesel engines, because these engines have a longer life, consume less, have more torque and are more efficient. Diesel is way less pollutant than many of the factories, pesticides on the crops, chemicals in our food and weapons testing. Maybe no more than petrol engines. I love Diesel.
I’d like to take a moment to recognize the peanut gallery with their perfect sound effect timing.
Love it

“Gas mileage can be reduced up to 30% to 50%” any references to back this up?
A normally functioning DPF will hardly effect mileage. A clogged DPF will reduce mileage dramatically. But a clogged DPF is symptom not a cause. If you have a DPF problem, check your MAF sensor, injectors, etc.
I still have the original DPF on my car with 235k on it. And it still runs like when it was new.
If a deleted diesel gets 50% better mileage, it would appear half as much fuel would be used. Then you get into reduced pollution from diesel fuel production, transportation, storage, etc. It's screwy to have all this crap on an engine to reduce vehicle emissions at the cost of increasing fuel consumption, decreased engine life, increasing vehicle maintenance costs, reducing reliability, etc.
I'm not a conspiracy theorist but I've always felt like the petroleum industry was in cahoots with the epa to increase fuel consumption.
Hmmmm....I'm sure that no pollutants are created while manufacturing the emissions components or disposing of them after they fail either...you raise a great point but unfortunately not many people believe anything other than what they hear on cnn

Chad Jessup yup, same with a gas pedal. Nope nope nope it’s a throttle pedal.
Man u guys must be fun at partys. You understood what he ment....
Agreed 100% . Diesel enthusiasts lose credibility with me when they associate the word "gas" with a Diesel vehicle. This gent is obviously a smart guy and has likely forgotten more about Diesel engines than I will ever know, so why he's using such a Diesel layman's term is beyond me. My wife is by no means car savvy and I could be in for an expensive surprise if I used the word "gas" when referring to fueling either of our Diesel vehicles. I use terms like "fuel oil", or the "green handle" or just "Diesel fuel", never ever "gas". It's like referring to an internal combustion engine as a MOTOR. It's NOT a MOTOR as motors use electricity to do work, it's a heat ENGINE period. Words matter and yes, I am fun at parties.
@@jackspence7779 Yes, and there is a huge difference between a motor and an engine.
I agree when I discuss mileage in my diesel trucks I refer to it as fuel economy. Also the DEF I buy is clear I think he said it was “blue like windshield washer fluid”. I agree with another comment that the best delete would be an EPA delete!
Recently had a DPF issue on my 2014 German performance SUV. Tried to regen with service mode or with high RPM on a highway and different additives with no effect. The cost replace DPF was around $5500, which is insane. Quoted $700 to $1k to clean, but no guarantee, it could fail in 6 months again. Also did an oil change and oil was very dark and thick, full of soot, making a huge wear on the engine. After a long research made a decision to do a delete and implement a Melone tune (ECU remap with delete) stage 2 on my TDI. It costed me $2100 for straight pipe, ECU remap and labor to put the pipes on. One of best decision I made. CEL went away, the truck got significantly more responsive, got plus 70hp, cut 1 sec on 0-60. MPG were improved by around 20% in city and 10% on a highway, giving me plus 50 to100 miles range on a tank. Got more range, power, torque, engine life and no headache over DPF/DEF. I am very happy with delete, highly recommend to diesel owners.
@@samly1762 You can install straight pipe in any muffler shop. ECU remap from TuneZilla is easy to install yourself. I am very happy with results.
A very informative video. We get robbed here in Commiefornia with extortion gas and especially diesel prices due to the parasitic tax and spend politicians. Now that I have ascertained that this garbage DEF system not only reduces my mileage it also causes more engine failures and one has less power. I will look into getting my RAM def deleted.

Thanks for this great educational video. Best one explained on UA-cam. 👍👍👍👍. Keep em coming. I’m subscribed. 👍👍
If you remember before all this EPA crap the engines were a lot smaller because they just didn’t need to be bigger to create enough torque to pull the Loads they are required to pull. So not only is the engine using more fuel to heat itself up, the engine itself is bigger than it needs to be to do the same job that used to do. The problem is that the diesel engine was too reliable and thats no good for the economy.. You used to see 30 year old diesels everywhere. Now they break before they’re paid off
@@jesseredfield8194 I just deleted and tuned my Diesel Sprinter van at 29K miles. It's out of basic warranty due to it's age (2018) NCV3 chassis made in Germany.

Man thank you for this video! I agree with every word you said. Great explanation of all this emissions bull****! Keep it up!
Another serious possible effect caused by one of these systems happened to me.
I had a 2007 Mazda 6 turbo diesel, which was fitted with a DPF. It was the first DPF equipped diesel that I had owned and I didn't understand how the system operated.
I had owned the car for about two years and it was nearly due for its annual service.
On my journey home from work one day, I was accelerating quite hard on a slip road, to join the motorway. On joining the motorway, I reduced pressure on the throttle,
but instead of reducing speed, the car continued to accelerate - pretty violently! In my confused state, I pressed down on the clutch pedal and the tachometer needle tried to wrap itself around the stop - at which point I realised what was happening.
What had happened, was the excess diesel fuel being injected into the engine, that was meant to force a regen of the catalist, had diluted the oil in the sump so much that it had raised the sump level to a point where it was being used by the engine as fuel. I was now dealing with a diesel runaway.
I managed to control my speed with the brakes until the sump level had reduced enough to stop the runaway situation.
To cut a long story short, the Mazda dealer didn't want to know, as I had been responsible for checking the oil level. They stated that the catalytic convertor was probably now 'junk', and would need to be replaced at a cost of about £2000...
I will never buy another Diesel car.
Gary, I wouldn't be surprised if Diesels are soon outlawed in the U.K. I've read that France has already set a timetable for eliminating diesel powered vehicles. I don't know how this is going to square with the Trucking industry over there, or if it's even applicable to commercial trucks. But, knowing the Bleeding Heart Environmental movement, I suspect that it does.

When I lived out in CA, all vehicles had to pass the smog test. Now keep in mind, just waving the wand in the air would show fail, due to all the smog, but once that air went thru the engine, it would come out cleaner than when it went in. My 74 Dodge Dart, 225, would average about 12 mpg. My buddy's 74 Nova with the 250, averaged about 8 mpg with all the emission controls. Both were new vehicles. My buddy moved to Ohio, stripped the engine of all emissions stuff, and mileage went up to 24 mpg. I moved to IL and just traded mine in.

A great alternative to the straight pipe delete is cutting the DPF open, clearing of the dpf element, weld the shell back together and reinstall. From a cursory look, the DPF appears to be installed ... but it's just a giant section of exhaust pipe. Delete DEFINITELY extends engine life. Get a little throatier tone to your exhaust, too! :)
BTW ... diesel trucks entering a hay field? Never happens right? The "genius" EPA goofballs ... yeah, put >1100 degree metal in contact/close prox to dry grass. what could POSSIBLY go wrong???

I was in a parking lot and backed into a spot with my tailpipe next to a rosemary bush. It was very hot out and I was waiting for someone so I kept the truck running with the A/C on.

In all seriousness- Im a farmer and we run tractors in idle as much as possible (throttle down, gear up) but emissions is brutal. If you haven't done enough high rpm the computer forces the engine to high throttle. For most applications this isn't any issue- except for spraying, where pto speed is related to volume and pressure output.
Pretty unreal isn’t it. I had this discussion with an acquaintance of mine that works for the epa. Friend or not he acknowledged this is simply done to “appear” as if they are doing something to help diesel admissions. He also told me they are fully aware they are actually putting MORE harmful chemicals into the atmosphere by requiring these products. The much higher quantity of fuel that is used to support these systems (and also the ammonia) ends up polluting more than it would if our diesels were left to run and breath on their own. It is simply an appearance for the liberals and tree huggers that throw a fit and really know absolutely nothing about what you just explained.
How are these systems putting more harmful chemicals into the air? I get that it seems like a terrible solution for engine longevity, but for what is coming out of the tailpipe, surely its better with the dpf and Scr systems.
@@JeLifeCoach It’s not that it creates more coming out of the devices. It’s the long term affects. You burn much more fuel to do it (which is the huge one) so it’s a null and void point. You have to think long term, not what is actually coming out of the tailpipe. Manufacturing (energy) of these components, disposal of these components, they contain harmful products, etc, etc. Yes, what’s actually coming out of the tailpipe is “cleaner” but at what cost? Plus it’s marginally cleaner. If a diesel is running properly and fueled properly the emissions are extremely low and non toxic. Plus, they the majority actually fall to the ground, not pollute the air. It’s all these assholes that don’t know how to tune a diesel and just add fuel. Had they not done all that bullshit with their black smoke, it would have never been an issue. I’ve built many Diesel engines and they are capable of a ton of power without the smoke. And actually are quite economical for the power produced. Nobody thinks of everything going on behind the scenes and downstream…..only that there is a sticker for the world to see that reads “certified clean idle.”
@@specforged5651 I first want to say thank you for your reply. I am new to all of this and I dont know anything.

I would love to learn more from you. My smog rating and emission rating per my window sticker is considerably lower that gas powder vehicles of the same generation so I know these systems work form the tailpipe as you’ve stated.
What should I do?
@@JeLifeCoach There are very very few who actually want to harm the planet. We are not out to destroy the environment by driving large diesel trucks and wanting to enjoy our hobby’s such as building engines and racing. It’s very similar to the two stroke four stroke argument. Funny how California “outlawed” two strokes except for “closed course competition” which is a huge portion of two stroke engines. Two strokes are bow making a huge come back in that world btw. The problem is they want their cake and want to eat it too. They want it both ways and that just isn’t a reality. The entire leftist and save the environment crowd always wants it both ways. In fact they want it every way imaginable. So their suggestion…go buy a Tesla right? And how do you think that Tesla is manufactured? By energy from windmills and Nancy Pelosi’s farts (prob could actually)? No! It’s manufactured in facilities that burn fossil fuels for energy and use extremely harmful materials in those batteries that have a very short lifespan. Then are what? You guessed it, trashed into the environment. And what are the vast majority of cars manufactured out of? Yep, plastic…..better known as petroleum products. And where does the energy to charge those batteries every 50 miles come from? Those same Pelosi farts and solar panels? Nope, the burning of fossil fuels. They act like they are the saviors of the world when in the long run they are many times making it worse. It’s ALL for show. I have zero problems putting emission helping devices on my truck if they actually are for the right reasons and actually do what they claim in the long run. It is all about the sake of them feeling better about themselves in the moment and to their extreme followers. Good news is most people are seeing through it and it won’t last much longer. They’ve dug their own grave and they’re about to lie in it because it’s all based on a lie and an “idea”, not scientific evidence, logic and realistic behaviors. My suggestion to you is stuck with your diesel, change the oil often, don’t let it idle and cross your fingers it will last that long. Because if it was built after 2007 with all of this ridiculous emissions crap on it, it will absolutely not. I have a 1994 12V Cummins truck I keep at my cabin that has 417,000 miles in it, blows a very very small amount of black smoke and gets 26 mpg. So you tell me what’s harming the environment worse. My new truck that gets 14mpg and has to be replaced 3 times as often, thus using more fossil fuels for energy in manufacturing, more petroleum products for all the plastic and about every other material made. Not to mention the harmful materials used in the manufacturing of the actual emissions devices. Which include heavy and toxic metals and materials. Or that old truck that has been around for 25years, gets the oil changed 1/4 as often and uses a 1/3 of the fuel. You do know how these DPF devices clear themselves of soot right? They inject a large amount of diesel straight into the exhaust to burn it off, thus producing a tremendous amount of pollutants (NOX) they are suppose to be filtering out? There is zero logic and realism behind it. Good luck my friend, keep up on the maintenance of that little diesel and I hope it serves you well. Plus a diesel station wagon!? Hell ya!
@@JeLifeCoach Oh and if your little diesel uses DEF. Put high grade DEF in it. Not the cheapest shit you can buy and definitely not the garbage at the pumps. It will save you down the road with def heaters, tanks, pumps and control equipment. That crap will ruin all those devices.
Less government more common sense
This exactly
I deleted my diesel and yes what this man I saying is very true. Very costly to do. I’ve never been happier w my diesel tho. I’ve increased my hp more then 50 % straight piped it and now that Turbo whistles. My Egr was fool of soot and took power away. I had a professional Program and Tune the motor and Trans post delete. I think it’s a good investment for your pickup and firmly stand by deleting.
The only thing that makes sense to me regarding the EPA's involvement in the Diesel's emission is to have a cow as a pet.
I deleted all that crap from my '08 Ford and it runs so much better and used so much less fuel. Highly recommended. People would be shocked at the cumulative carbon footprint of all the DPFs in the commercial fleet.
Does your car blow black smoke after the delete? I am thinking of removing mine but worried if it will blow too much smoke and attract too much unwanted attention.
That black smoke is soot/unburnt fuel
Any good tuner can make it run clean and not output it
Uh.... on my friends 2018 ram that is deleted we found that if the turner does a good job it still burns extremely clean. It can be ran on its highest setting +200hp and you can only get any smoke at low boost which with the newer turbos isn’t for very long. Biggest thing I noticed is that the stock turbo went from running 26psi max boost to 39psi max boost. That for obvious reason adds a lot of power. Didn’t notice any increase in fuel mileage however didn’t see a decrease which was surprising considering how much more fuel is added to go along with the extra 13 pounds of boost. So far so good. Unloaded probably 500# worth of crap off the truck and dropped the egt considerably. That’s all due to the huge reduction in the exhaust back pressure. This is his 6th deleted ram and will do it again. This one was deleted at 140 miles and it was amazing how much build up was already in the egr cross over tube. Also another thing to consider is how extremely corrosive def is. It’s literally liquid urea which is used as a nitrogen fertilizer on farms across the United States. Great vid. Thanks.

The cost of owning a 6.7 is too high unless you have money to burn. If I was to buy a new truck today, I'd get the gas 7.3.
I did my delete after ram said my new turbo would cost me $3500 to replace at 38k miles! the cause was 1100 to 1200 EGT's . sent it out to a rebuilder for $800, cost of delete $800, so for $1600
its fixed for good. now It wont reach 1000 EGT on big hills hills towing 20k lbs. the black soot is no longer being sucked into my motor making it very happy and I have more MPG and much better power with no smoke. I left the stock muffler on so its not noisy but it has a sweet rumble now that makes me smile all day.
Even with soot being heavier and settling to the ground more quickly than other particulate matter, it doesn't dissipate fast enough in most cases to not have an effect on the environment in two major cases:
1. Highway driving. Many times I've driven behind heavy duty trucks (dump trucks, cement trucks, etc) or light duty pickups. Not always, but not uncommonly either, I am behind one that likely has had some sort of exhaust system modification, and lots of soot/smoke is blowing out of the tailpipe, or upright stacks. I'm effectively driving within a smoke screen of haze and fumes that at the very least dirties my car, and at the worst, is pulled in through the hvac system into the cabin where I'm breathing air. The only option is to speed, and pass the offending driver to get back to driving in cleaner air. In my opinion, it's incredibly obnoxious and really unpleasant to just be stuck behind a, for lack of a better word, smelly truck. In this case, the soot cannot fall to the ground fast enough as I'm about 1 second of driving distance from the truck.
2. City/urban environments. Walking along a sidewalk in a city, and finding yourself next to a truck that has exhaust modifications mentioned above, you'll find yourself walking through a cloud of soot or fumes. Again, sure the soot is heavy, but if I'm walking down the sidewalk and a truck accelerate from a light and goes past me, it leaves me and other pedestrians in a cloud of unhealthy fumes. The soot doesn't fall to the ground fast enough before me and others are forced to inhale it because there's no clean air around for the next 20 seconds or so until a fresh gust of wind dissipates it.
People will probably say my comment is gay or something stupid but I'm just being real. The "heavy soot" excuse is one that drives me nuts. Yes it's obviously heavier and will fall to the ground but that doesn't mean everything is all well and good. Thanks for the video, watched this because I'm curious about buying a Jeep Ecodiesel and have seen the emissions systems can be pretty maintenance intensive on them.
Very well written. I’m all for maximum freedom and upholding the constitution in terms of maintaining states rights, the issues you mention could be addressed better by local and state governments instead of the EPA whose authority is too far overreaching. In simple words yea it would suck if an emission deleted diesel truck drove by a downtown shopping street filled with pedestrians enjoying their weekend with family.
If any car or truck is emitting black smoke out of their tailpipes there are mechanical issues. A normal tune doesn't allow that. it's these idiots that think "rolling coal" is cool, that drives me nuts. They're the ones that are ruining it for everyone.
I have the 3rd gen ram ecodiesel and it's a wonderful engine. Highly recommend it
Deleted my pacar 8 2006 model. You are right +30 mileage more power. A joy to drive now
This was really interesting. What I have not seen is reasonable effective emmissions control measures. It's a little like if someone had an amputation deciding the solution is to cut off the good leg to make it the same length. Carbon emmessions can be cleaned up through proper tunning and a catalytic convereter to completely the cumbustion reaction. The NOx issue is better handled by reducing or emoving N from or again by introducing H to the combustion cycle either trough direct injection of H2 gas into the combustion chamber or catalytic converter or with NH4. The biggest change would be oil companies pre treating diesel fuels with solvents to completely remove Sulphur and nitrous compounds in the fuel. Biodiesel blends can substantially reduce NOx and SOx emissions.
So I say get on the case of fuel producers to develop a sustainable product, not the individual auto producer or auto owner.
True enough, as many people piss and moan about biofuels taking away all the food from everyone but they wanna bulldoze every single strip of farmland in sight to build subdivisions
Diesel injectors and fuel pumps are lubricated by the sulfur in diesel fuel. If they remove sulfur they will have to put something else in its place to keep the lubricity.
In fact modern "low sulfur" diesel fuel doesn't lube nearly as good as it he old stuff. So now you have people who own older diesels pouring 2 stroke oil into their fuel to help lubricate the injection pumps.
I said piss on the warranty and deleted my new ram!!!!
perashmura I was at the local dealership when a guy came in with a late model deleted pickup he wanted to trade in, the dealership told him the truck was worthless to them, warranty VOID and they can’t sell deleted vehicles.
Private buyers should also beware of deleted vehicles, you’ll be stuck with them unless you find another private party to sell to.

Wow! You should teach a course on this! I pull a 10,000 lbs. gooseneck horse trailer, and am trying to decide if I should trade in the 6.0L gasser for a diesel for better fuel economy and longer engine life. Your video supports previous advice to buy a gasser if I want a 2010 or newer truck. I've read there can be stiff fines and penalties in every state for driving a deleted diesel truck on roads.
THANK YOU for uploading this!!! Live long and prosper!!!!
The CEO of RAM once stated the 6.7 technically runs clean and doesnt need any of this BS and the only reason it has the Egr is because the government said so. True?
No. If it can pass requirements with unicorn tear injection and nothing else that would satisfy EPA.
@@creigmacc unicorn tear injection?
@@cynicaltexan9639 an exaggeration to point out that whatever gets you compliant with EPA requirements is what matters. With current technology there's no way that can be done without EGR, or you can bet it would be gone.
When the Cummins 6.7 first came out in the Ram, it did not need DEF/SCR to be compliant but it did have EGR and DPF. Later on DEF/SCR was added to the 6.7 when regulations got tighter
@@creigmacc EGR does the same thing SCR injection does but EGR shortens engine and oil life and increases load on the cooling system. It is an extremely outdated way of reducing emissions.
You could go DPF/SCR only and meet emissions but that would increase SCR usage and people already hate having to fill it with current usage rates.
Great video on how this all works. Both my daily driver and hotshot truck uses the 7.3 Powerstroke which thankfully has nothing to delete. I am planning on buying a semi soon and already knew I wanted a pre DEF truck and will buy one that is pre 2000 if possible. There is a tradeoff between comfort in the cab and engine performance / reliability. I think I will choose to be more comfortable when I retire and not worry about it while I'm driving.
If you can get a N14 power plant one of the best engines ever made I worked at a KW dealership for 25 years and can still count on 1 hand how many I overhauled they do have a few problems but nothing major unlike Cat or Detroit
@@davidsignor7931 I wound up buying a 2010 Peterbilt 387 with an ISX-15 (CM-871). Dealer said it was a 10 speed... guess they didn't know what the little red lever on the shifter was for. Turned out to be a 13 speed. I wasn't mad... makes it better for hauling heavy flatbed loads!
I want to delete my 17 Powerstroke but after 41k miles it’s been an amazingly reliable and dependable truck. I have an extended warranty from Ford, dealer sucked big time and the GM purchased it as part of the deal, to 100K miles. So I think I’ll wait till then to delete it since I’d have to clean or replace the DPF at 125k.
Easy decision when its 1500 for a delete exhaust and a tune, or 10k+ labor to "fix it" for you.
Deleted EGR cooler, valve and all the exhaust crap on my 2011 Ram. Used PPEI system including tuner. Runs soooo much better and no coal out the back. Easy to do and would highly recommend it!!!!
What was your costs?
Anything that reduces the fuel consumption per horsepower hour is ultimately a reduction in emissions. When I delete, the first thing to go, is the EGR. I think you can avoid deleting the DPF and SCR by driving with gradual movement on the accelerator, giving the turbo time to spin up as you need more power. That prevents "rolling coal", because of the sudden increase of fuel, before the turbo has time to spool up to boost. Smooth easy transitions in throttle will allow the computer and turbo to adapt to the new demand. Less particulates, less need to regenerate the DPF, and maintaining the SCR.
I've never owned a GM diesel equipped with a SCR. How much DEF does it use per 20 gallons of diesel fuel? How expensive is it? Do you just add each time you fuel up?
Very informative, I thought the SCR took the place of the DPF, didn't realise the most recent diesels still had both. And "diesel exhaust fluid" is called "AdBlue" here in the UK
Actually a lot of tractors are running non egr, non dpf engines with nothing but an scr just tossed on there by itself and they're beasts
@@wizard_of_poz4413 Would there be a benefit from deleting my EGR but keeping my dpf and Scr. I care about the environment and my engine!!!! What do I do?
@@JeLifeCoach I seriously doubt it would work. Besides the dpf is hard on your engine
@@wizard_of_poz4413 what would you recommend? Is there a balance between longevity of cars engine and also emissions?
@@JeLifeCoach idk I mean just don't run a crazy ass tune and you shouldn't produce any smoke even with a straight pipe
We have 2 very unreliable 2012 duramax. Deleting def and part. Filter was the only option for reliable operation. Cost 900 each. Trucks have run over a year without fault.
south texas we have a 2012 and it always needs to do a regen and in Canada it’s too cold outside to do it so it then needs to limp home
Ha, same thing for my buddies Duramax, It was a absolute turd when he got it. Now that he deleted the EGR its running smooth as butter and spends time in the garage instead of at the dealership
Wow! Thank you. That was the most helpful video I’ve seen. My brain is wired to find out the how’s and why’s. And you nailed it. Now I guess I need to look over my warranty and start saving my pennies. As soon as it’s safe to do some deletes, it’s done.

i recently bought a diesel mercedes and am having issues with the nox sensor. This was very informative
Super funny thing was when they started the DEF diesel pickups. In Canada, the DEF fluids would freeze and leave guys stranded. So DEF delete became very common. Then GM put their DEF fluid tanks underneath the passenger side front seat. Then guys drove on logging and oilfield roads (very poor) and bottom out and break those tanks. So DEF Delete was MANDATORY.
You got an antifreeze line going in the tank for that reason, so that's kind of a lie
I never knew how diesel emissions systems worked, now I know they are worthless! Thanks lol. Make more videos!
The new control devices make the engine wear out faster, so you must by a new engine sooner :: handy for the motor trade.
At my age, sometimes I get nostalgic for the full old-type diesel exhaust smell.
And the sound! All tractors and trucks sound like like vacuum cleaners now. No more good exhaust soundd
@@lordoftherims436 I remember the old proper full diesel brrrrm noise. I read once a truck driver complaining that all the junk that he must put in his diesel exhaust stream is cutting down his engine's power: " _Let our diesels breath freely_ !".
The guy coughing off screen while he talked about NOx is a nice touch
Deleted dpf on my 09 Cummins increased mileage from 14 to 20 plus I get 14 towing a heavy trailer now when I got 9 before it’s a tremendous mileage boost to delete
As a H,D Mechanic I work on these systems weekly. All of our oil is tested at every service we don't get diesel dilution without a bad injector, bad quill tubes or bad injector lines if run under the valve cover. Re burn systems do not cause diesel dilution in the oil unless the system has failed.
I have never understood the logic on this either. Burn more fuel to "reduce" emissions. In over the road trucks the numbers are staggering. As far as soot, with today's electronic injection, there is no reason why a deleted truck that is tuned properly should make soot. But I digress. All this emissions hardware runs up the initial cost of the vehicle, is marginally reliable at best, and, as mentioned, actually causes more fuel to be consumed. Government logic at its best. I am left to conclude that they actually have all the regulations surrounding diesels in place so that owning one becomes less attractive. Why? If diesels caught on and vehicles routinely got 30-40+ mpg, people would buy them in droves and the ultimate demise of the internal combustion engine would be postponed. Yes, I think the Left and the government ultimately are so rabid about the theory of man made climate change that one of their goals is the demise of fossil fuel use. One way to do that is to make efficient fossil fuel engines unreliable and impractically expensive.
I'm no tree hugger but there are cities with high levels of toxicity in the air and NoX is part of the problem. I don't judge a guy that deletes but there is definitely a reason why these measures were put into place. A guy driving through the country with no filtration/treatment on his/her diesel truck is different than 1,000 busses idling in a cramped city with thousands of of people filling the sidewalks around them.
@@ayliniemi How is NO2 part of the problem specifically?
@@ayliniemi Exactly why many cities are switching their diesel fleets to CNG and LPG.
The largest concern anyone would have is, it's not efficient, period. No one with an IQ above 80 would even consider a system like this.
I have a vw tdi golf. Have gotten as high as 60 mpg.
I can guarantee you that if the EPA/CARB was paying for the extra fuel used, 30 to 50%, to run a DPF and EGR, they would find a different system to control emissions. But, since the public is the one who pays double in fuel consumption to produce "less emissions", they don't care about that even though they are the same entity who mandates and tells auto manufactures to increase their fuel efficiency. Imagine that, the EPA allowing less MPG on diesels all while they are mandating more MPG ! This concern reminds me of the 1970's when engine compression went from 11:1 down to 8.5:1, EGR was invented and then catalytic converters that smelled like rotten eggs. MPG went from 18 to 22 MPG down to 8 to 10 MPG and folks had overheating vehicles in masses.
Excellent point!!! Oh, they are concerned with our health! Ha! Bologna! What's the real reason! Could it be..... MONEY!!!!

They fixed a lot of the issues on this engine. One of the biggest things is you get the EGR after the DPF so it’s quite clean now. Do 4000 mile oil change. I run 85+ redline additive in the tank as well.
I hope you were able to escape the EPA agent who kidnapped you and forced you to type that.
@@johnd6980 😄😄😄
I don’t want to be disrespectful but you are misleading on some of your information.
There’s not a muffler on these newer Diesel engines. The aftertreatment system muffles the exhaust enough to where you don’t need a muffler.
The engine produces NOx, Soot/Hydrocarbon (HC) and also burns oil. Every engine burns a little oil although most can not be recognized.
The DOC is used with the DPF. It’s not separate, it’s mounted right in front of the DPF. The DOC does nothing but creates heat in the exhaust. There are 3 fault codes associated with this and they are 2639, 1921, 1922. You’re talking about a stationary regen and it only happens when you idle a heck of a lot or if you have excessive oil consumption plugging up the DPF. Post injection occurs when the injectors inject fuel during the exhaust stroke. Now speaking with just Cummins engines for a bit. The aftertreatment injector was used on heavy-duty engines (M11, ISX12, ISX15) and goes behind the turbo and inlet NOx sensor but this method is not used anymore on their heavy-duty engine products that are 2017 and newer, they all use post injection now. Anyways, this fuel reacts with the platinum within the DOC raising its temperature around 343°C (650°F) and this is hot enough to atomize the soot within the DPF. The soot in the DPF creates heat when it atomizes raising the temperature around 565°C (1050°F). If the temperatures get above 593°C then it starts the melt the substrate within the DPF. The ash does not get atomized. It stays in the filter and is what gets cleaned out when the filter gets cleaned. Ash is additives from the oil. Post injection does not wash the cylinder walls or dilute the oil. It’s not even a full injection. It’s just a quick small injection, doesn’t affect fuel mileage any.
Soot is not heavier than air. Smog? California? Soot is hydrocarbons and this along with NOx can mix with moisture in the air producing acid rain.
SCR stands for Selective Catalyst Reduction. DEF is a 32.5% mixture of synthetic urea and the rest is deionized water. It’s made to freeze and once it thaws it goes back to the 32.5% mixture. Age does not make the DEF crystallize but DEF does degrade overtime. The shelf life is two years. The computer looks at the inlet NOx sensor and outlet NOx sensor to determine how much DEF is needed to inject. Once DEF is injected, the water atomizes from the high temperatures and you’re left with the urea. This reacts with amox brick and scr bricks within the SCR converting the NOx and HC into CO2, H2O, and N2. The SCR is a full flow pass through device which is very hard to plug with soot. If there is an excessive amount of ammonia coming out of the exhaust a fault code with be logged. On Cummins it’s a 3582 or Selective Catalyst Reduction Conversion Efficiency.
These engines are designed and built with these components in mind. It’s done to be able to sell engine within the North American market. It’s not something Cummins, Detroit Diesel, PACCAR, Powerstroke, Duramax or any other engine company wants to put on their engines for on-highway use. Off-highway is a completely different discussion with their Teir 4 Final emissions. Euro emissions is a completely different discussion with Euro-6 emissions. It was great content just some was misleading.
Standing up, hat’s off, and clapping. Great video… taught me a fair amount.
I now know what my mechanic is talking about thanks😂
it is known that diesel fuel combustion engines produce much lower concentrations of carbon monoxide (CO) than gasoline engines
It's the N0S that's the issue. I wouldn't have a newer one without DEF. The prior choked ones ate fuel and clogged the EGR. DEF allowed the engineers to detune the emissions somewhat. Different brand but my friend maintains four F-550's with DEF and none have had an issue in over 100K of abuse. If the election goes the way of the Dems,the war on diesel will escalate exponentially. I'll keep my '07 5.9 with internal EGR.

@@abramspearman9046 Boy it's been explained on the TDR site but I can't recall Guy's will install aftermarket cams that correct the issue.

You explained this very well . Most people don't know the reasons to do this other than the Horse Power reason. My truck actually runs smoother and like I said way better gas mileage . I get 27mpg on expressway in the winter gas and 30mpg on summer gas with HotShot Diesel additive .
Winter Gas?? Summer Gas?? WTH??
I used to live in Michigan and in the winter they add stuff to the diesel fuel so it doesn't gel up from the cold and it makes you get worse gas mileage.

The doc is an important part of the diesel fuel chemical reaction needed to increase EGTs to burn off particulate matter caught in the substrates in the dpf and decrease nox. Other than that great simplified demonstration. I have wondered though if you delete the egr cooler do you lose any air mass. Probably not a lot as long as the tune makes up for it with the VGT on the turbo. but what if you don't put a delete tune and just plate off the egr cooler like so many 6.0 owners do and just deal with the CEL for egr insufficient flow. Is there less air flow than normally requested? And could drilling a hole in the egr passage way in the intake with an air filter be a good way to bring back that air flow and replacing the dirty egr gases with clean air and taking the CEL away? Might try it on my 6.0 and let you know on a dyno if there were any differences. - Seth Mazza from va
