Most big brand diesel fuels include conditioner. Conoco specifically says their fuel has 30% more than Toptier. Shell markets their dynaflex conditioner as cleaning existing carbon deposits off the injectors and keeping your engine running smoothly. The Toptier recommendation seems to be a floor rather than an exclusive option. As long as you're buying quality diesel from one of the major brands, you should be fine without adding your own conditioner.
I just watch you vid, great info thank you. I live in Edmonton Alberta Canada and I did go the "Top Tier" fuel website and clicked on the "station finder" and then on "my Location" and it gave me one more station that wasn't on the list, it gave me "Shell Gas Station". Try to enter your location, may be it will give you other ones. Nevertheless, I have a Coop and a Shell just up the street from my, my Costco close to mu place does not sale diesel. Keep the 3.0L diesel video coming, I enjoy all of them.
I’ve had the 3.0 for two years and 50K miles I’ve always used Hot Shots Secret EDT in non cold weather months and the Winter Formula here in NY from November through March. I have never had a problem and have never had a lag in power or performance. I did the math and it’s costing me an additional .27 cents per tank to keep my fuel system and injectors clean and maintain my performance. You can buy direct from them in bulk and they usually deliver within the same week. I know i might sound like a commercial but i went from a 5.3 2005 Sierra to a 2021 Duramax and have not had any negative experiences at all by simply using an additive every fill up. BTW I’m averaging 27 MPG in an AT4.
@@geraldkoth654 yes though commercial diesels are only as sturdy as their after treatment systems, and none of those last anywhere near the lifetime of the actual engine.
Ummm you do need an additive. Especially if you plan to keep it long term. Diesel fuel in America is not as high quality as Europe. So run hot shots secret EDT if you don’t want to rebuild your fuel system.
@@ebindy4951 I think I will, I have had many diesels but try and trade at around the 150 thousand mile range. Diesel is already high enough, just didn't won't more expense, might change my mind if I screw it up though with no additive. Thanks, I'm going to start using it now.
well thats me screwed i have been chucking canola oil in my tank for years [ veg oil ] i supose im lucky i run a 22 year old 2.5 L vw and it dont care what fule it gets :) i have done 150 k on veg oil with no problems .
I use Hot Shot secret diesel winter anti gel every fill up in the winter time and the Hot Shot secret everyday treatment when I fill up during the warmer months.
Same! I see smidge better mpg in city but it makes me feel better on the engine longevity if I always use it. At 12k miles on my 22 LM2 and hoping to keep it past 300k if she survives.
Same on my 3L TDI. I have a Costco on the north and south of Indy with top tier diesel but not always convenient to fill up there so Hot Shots for my diesel to keep the fuel pump happy 😂
Same here with the Hot Shots treatment. I use Shell diesel and see an improvement in fuel mileage over lower quality diesel. I have done fill ups back to back going the same route, and get 3 to 4 mpg better.
That's exactly what I use in the summer months here in South Dakota. seems to help with MPG especially when towing and at least to me the engine seems quieter. Winter I use power service for anti-gel even with our "treated" or blended fuels. Just a little extra insurance against gelling up.
Tim I think the take-away here is that it's a good idea to use an additive with your diesel fuel, the ultra-low-sulfur fuel the US has does not lubricate the injection pump & injectors enough.
I have an old GM 6.5 in my truck, one on my boat, and several diesel generator sets. I have been adding about 70 to 1 ratio of two stroke outboard oil to my fuel storage tank. I do not see any harm at all to any of the fuel systems with my Stanadyne , Perkins , and Kubota injection pumps and injectors. Besides, I have a pallet of the 2 stroke lube after the boat shop went belly up.
You're not wrong but at the same time though this has been a standard for a very long time and I'm getting kind of annoyed that oems don't cover injection systems with the fuels available in the markets that they sell them in. Sure I understand if there was like a water contamination situation that's fine the gas station pays for the entire repair bill. But when they say at 60,000 mi the injectors aren't covered even though you're in a 100,000 mi warranty that's BS. Either to build it to where it survives the areas that you sell it in or don't sell it there
That's strange, don't they have anti wear additives? I use Neste HVO in my boat with Volvo Penta engines from 1986. It has AW additives and should be as good as any diesel fuel in terms of injection pump lubrication. It's approved by Volvo Penta for all their engines. HVO without AW additives would surely kill the pump in no time but I'm surprised that any fuel is sold with too bad lubricity.
After watching your video, I ran across this statement from the Top Tier website. No wonder why Ford and GM in particular are pushing Top Tier diesel or their supplement in GM's case. The TOP TIER™ Diesel Fuel program is currently sponsored and overseen by General Motors, Volkswagen, Daimler Truck, Navistar and Ford - and recommended for both heavy- and light-duty vehicles.
Optilube or hot shots EDT are two great products, 136,893 miles so far on my 2016 Dmax, no problems. By the way, ac delco additive, is a rip off. Stanadyne is the one who manufactures it for GM, I believe. Stanadyne is a great product, but I believe optilube provides the highest lubricity, 2nd goes to hot shots. I would go with hot shots for ease of use packaging, over opti lube. I would also recommend a FASS lift pump for ultra filtration of your fuel.
You're looking way too much into it I run whatever diesel I can get with hot shots secret everyday treatment one oz at Fill up and I have over 250000 miles
You're reading too much into the Top teir reccomendation. It is a quality assurance measurement for marketing purposes. Think of it like the Dexos licensing. Just because an oil doesn't have Dexos on the label doesn't neccesary mean it doesn't mean it won't meet the standard. It just means they didn't pay the license fee and submit it for testing. The key to diesel is to buy from a reputable retailer that turns over fuel often. Additives aren't required.
I would like to see what the actual sulfur is in the different diesels at different stations. From what everyone says it should be ultra low sulfur per us regulation. Maybe they just didn't update the sticker or maybe it really is low sulfur.
I’ve been happy with HotShot EDT in my Cummins. 99% of the time I fill up at Sinclair, they advertise “Elite diesel” with additive packages containing detergents, lubricity improvers, water separating emulsifiers, higher cetane, and cold flow improvers.
Hey Tim, I believe this is just GM stating to use the best fuel possible and that would be Top Tier, to ensure the best performance. Which, if you think about it is a “duh” statement. Of course using better fuel with more detergent to keep injectors clean will be better than not. That said, I agree that the manual shouldn’t be written the way it was. It instills fear in owners where there shouldn’t be any. We’ve all known for quite some time, even in gas engines, that injectors can get clogged and detergents in the fuel helps to prevent that. In the absence of detergent fuels, fuel injector cleaners can be added to the tank to clean injectors. In the case of GM and the diesel, of course they’re going to only recommend their own cleaner. I’m planning on buying an AT4 with the LZ0 (drove it and loved it) and I’m not fretting over this in the owners manual.
It’s not a “duh” statement. GM should be informing every customer for this truck that they should use that fuel or get the additive for lower quality diesel fuel. And they specifically told Tim to use the top tier or add the additive to his fuel for a longer lasting engine. So many people in love with the GM half ton diesels and they’re really a rip off. Diesel costs more pretty much everywhere, then you gotta pay for your def fluid every so many thousand miles, now if you own a GM truck you better be using the top tier diesel or putting in your additives. Just one more thing to the list to maintain your GM diesel half ton properly. Glad I stayed away from their diesel. If you can find a new GM V8 missing the cylinder deactivation that would be one to consider but then they have baby fuel tanks so if you tow lots your range is limited.
Hey Tim, I worked at a diesel injection service shop for a very short spell right after the ultra low sulfer diesel hit the market. We were a Stanadyne dealer, and we sold gallons of their fuel additive. I don't know if it will meet GM's standards but after running it in a 7.3 it made me a believer. The injector noise quited and the shake the early 7.3's had was minimized.
The ford 7.3 is hard to kill as long as you take good care of them you know general oil changes and fuel filter you can abuse a crap out of them and they will just keep on running
Costco use Nestlé renewable diesel. Also all the 76 brand in California uses renewable diesel all Arco stations south of Turlock, California uses renewable diesel.
The hot setup is to put 8 oz of 101 into the diesel fuel when you fill it up that will put lubrication back into the fuel and make you have more horsepower and make your fuel pump last longer or use 8 oz of ATF fluid which will help lubricate the injectors and your P4 fuel pump
Tim - using an additive is recommended for ALL diesels, especially here in the US where the diesel is of subpar quality to the diesel in Europe, and due to light-duty diesel vehicles also being much more rare here in the US, the diesel tends to sit longer in the tanks at a station. I use Stanadyne, it’s the highly recommended brand by many professional diesel mechanics. Does come out to about $10/bottle or $3.33/20gallon fill-up. Thanks for the great content!! 👏🏼👏🏼👏🏼
@@billoyler8041 no, personally I use it in an ‘05 Jeep 2.8 CRD, more or less same engine as the 2.8 Duramax - but additives are recommended in all diesels due to fluctuations in quality etc…
Stations know how much product they sell and place their orders accordingly. If they only sell 500 gallons a week they don’t order 5000. I do agree with using additive, I like PowerService.
I’ve been using Exxon Mobil Synergy Diesel Efficient fuel. I have a a ram ecodiesel best fuel I could find in my area . Truck gets better mileage 1 to 2 mpg better than the SHEETZ brand I was using
This top tier is a marketing scheme and BS. Worrying over nothing, and making a mountain out if a mole hill IMO. I run mostly Sinclair in my 3.0 and Amsoil fuel additive and truck runs awesome and gets great fuel mileage.
IMO you need to run a good additive. All the good things really needed to lubricate have been removed, repairs are stupid expensive its money well spent and its not as expensive as the GM Products hotshot archoil both good products
I am lucky, there are many stations in my area that serve Top Tier fuel so I plan on using it. If traveling I am okay using whatever I can find, I doubt I will carry additive with me.
That sure is a nice truck but sadly owning any diesel in any of the big 3 are terrible expensive to maintain for average Jo driver there made to work everyday. It's sad because the truck your driving is so refined and awesome to drive normally. But today a diesel will never beat a gas for your pocket book. Def, expensive oil , filters , and timing belt replacement, it's just to expensive of a truck
You clearly have never owned, driven nor worked on the 3.0 Duramax. Oil isn’t that expensive, it uses timing CHAINS and the oil filter is very cheap. $10. Ignorance about Diesels is a very American thing.
My 2020 L5P Duramax driven 17500 miles last year and about 1/2 the miles towing an 8K Lb. Travel trailer. DEF $130 and may be more if towing more. Last year DEF was about 2.5% of fuel use Oil change - $50 for 2.5 gallons Mobil Delvac Extreme full synthetic 15W40 and $11 filter Fuel filter - $24 about once a year Air filter $22 The only additional expense is DEF and a little more for a fuel filter. Not ‘terrible expensive’ and about the same expense as my ‘17 6.2 Silverado where I run premium when towing for better performance.
Your trucks are Awsome like i said but diesel cost more than gassers today in the long run . And 3.0 diesel has a timing belt that needs maintenance by splitting engine and transmission
@@andyw8082 The belt you are referring to is the oil pump belt. But you are correct that it requires the separation of the engine and transmission at 150,000 miles. EB Indy didn't tell you the whole story...I guess diesel ignorance is not just an American thing 😏
It appears that "Top Tier Diesel" is marketing hype. It appears to be a standard that few suppliers will subscribe to. Probably because that little sticker on the pump will cost the station a fortune.
Mobil Diesel Efficient™ fuel is fully formulated and pre-additized at the terminal, eliminating the need for off-the-shelf additives and saving you time and money. It’s engineered to clean up and keep your fuel injectors clean to deliver the power, reliability and productivity you need from your equipment. Sounds like GM needs to recommend Exxon/Mobil fuels like they do Mobil 1oil.
Add AMSOIL fuel additive and buy fresh fuel from one of the majors like Shell or ExxonMobil. That's all ive done in my 2020 2500hd. No issues and 75k miles
I got a 2020 2500hd Diesel, have 50k and don't use additives and just go to the main stations or truck stops. I am just amazed at these people dropping 12 bucks per tank on top of the diesel price. Crazy.
Umm nope. This is why I didn't buy a gm. And stayed with Ram. I had no reason to avoid gm and when it came down to it I heard about this top tier shit from a relative. Well, I have no interest in driving farther than necessary. Once per tank times $19.00 times 1.5 fill ups per week and 52 times a year and the average of me keeping a truck of 10 years comes out to nearly $15,000 extra to have the gm. Haha! No.
I guess if you dont mind taking your vehicle to dealership and leaving it there untill they get to it and wait for the parts to show up for warrenty work if it is in fact a covered repair dont use the proper fuel or additive/buy the way in best interest for yourself to use fuel treatment as recommended/non diesels as well/recommends additive at oil change/guess what/my truck has 450k on it never had a fuel pump or injector!!!!!! You decide what is right for you. Master certified ase techs advice.
Nothing but gimmicks. You'd be much better off just replacing your stock fuel filter with a 2 micron filter from CAT or another brand like that who has actual 2 micron filters. You'll need to change the stock fuel filter housing nipple to fit the larger CAT filter (kits out there), or better yet, replace the entire stock fuel filter housing. Do the same with oil filter housing, or get an oil filter relocation kit. Then you'll have a real defense against fuel contamination instead of buying snake oil every time you fill up. If the manufacturer told you they recommend you piss inside the fuel tank right after each fill-up, you might then draw the line and ignore them? I just draw the line sooner.
Tim I have a 2021 jeep eco diesel. I fill up a Wawa using their diesel fuel and at every fill add hot shot Everyday diesel treatment(EDT). I have seen a difference in fuel economy and I have only 6800 miles and have only had one regen. At the 6500 mile mark I put in extreme diesel treatment helps do everything you are concerned about. A.C. Delco is a gm product that’s why they want you to use it. EDT I use at every fill up and only 1 oz per 20 gallon tank-and the other one every 6000 miles. I swear by this stuff. I hope this helped.FYI… I drove from Orlando Fl to North Georgia one 3/4 tank of fuel and got 26 mpg.
GM has recommended Top Tier fuel in both gas and diesel for years in the owners manual. Dexos oil and top tier fuel were listed in my Camaro ZL1 and my wife’s Chevy Equinox. This is not an issue, just use the best quality fuel and oil you have access to and you will be fine. I don’t use small off the beaten path fuel stations or cheap oils in my vehicles hence why I’m still driving my 2001 Chevy Tahoe with 300k miles on the original engine.
512,000 miles on used fryer oil...First Gen 12valve VE fuel pump Cummins B6...never missed a beat! This sounds like a scam...like gallons of (prop wash) or a cargo bin stretcher or Diesel exhaust fluid!
It’s just marketing. Auto companies partner with other companies to recommend each other. General Motors offer Costco membership discount on their new vehicles that they sell. How do I know? Because I sold GM vehicles for a few years.
I use Hot Shots Secret Every Day Diesel additive in my 2019 L5P in summer and their Winter additive in cold weather. Used those products in my 2004 LLY and my 2013 and 2015 TDIs as well. One ounce treats about 20 gallons, costs less than $2.00 per ounce.
You are reading way to much into this! It's just a recommendation telling you to run premium diesel. Never had a problem running any diesel. Just add a fuel conditioner like hot shot secret, power service and so on. If your this worried about it then you don't need to be driving!
I use hot shot secrets diesel additive. It’s at Walmart for $14 a bottle and it treats up to 400 gallons. I did some research on all the additives and hot shots seems to be the best one out there I have noticed a difference in fuel mileage and they also have anti-gel and stiction additive.
Sir they are diesel trucks diesel fuel is diesel fuel put fuel in drive change oil and filter and change fuel filter keep up with required maintenance. Once again they are trucks with diesel engines not race cars lol i have owned 4 diesel truck maintenance is key good luck
Fuel where you want and add Hot Shots Secret winter formula for winter Every Day Treat spring summer fall. Call it a day…..but for real, Diesel trucks are becoming too expensive to run daily. I own an Alumiduty and an LBZ and the expense is pushing me more and more to just use them for towing and just run my Tundra for daily because it checks the boxes for less money daily…..
The word they use is recommended, if it said must use, they want to void warranties. Just a marketing plow to sell delco additive. Since the salesman did not disclose that to you on sale of unit, GM needs to deliver the fuel to you at no cost, at minimum give you the additive at no cost, I doubt they will, easy class action suit.😊
Just buy hot shots additive it’s concentrated and 1 bottle treats up to 400 gallons depending on which one you buy. They have so many different ones to choose from.. don’t waste money on ac delco. Gm wants your money
thank god I live in Canada as all our fuels have the conditioner and detergent already added we only have 2 grades and the second is just a high octain based fuel but our government has mandated all fuel be top tire standard so up here GM lies by saying only the 3 offer it as they have a partnership with these service stations but its false all diesel fuels in Canada meet the top tier standards as regulated by the government that is why our Diesel fuel is so expensive
Just saw Mobil Enhanced Diesel fuel at a local station. About the same price per gallon with extra detergents added at the terminal to help engine run cleaner and " get 2% better fuel economy" according to Mobil. Sounds like a better alternative than a $17.00 bottle every fill-up or 2.
Living in northern Indiana I fill up with Country Mark "Diesel-ex 4", which they advertise to be full of extra detergents including added cetane and lubricity ratings. Meijer also advertises the same in their diesel fuel. There are plenty of other options of nationwide to buy diesel with added detergents as compared to #2 diesel. I agree that "TopTier" is just a marketing gimmick that Ford and GM are a part of.
There’s probably a separate line at the power service plant with AC Delco bottles getting filled with the exact same stuff🤔. That way GM can charge $18 per tank while PS costs about that for 10 tanks. 😏
Please don't fall for this scam. Ultra Low Sulfur Diesel sold at all stations is perfect for your diesel engine, unless you buy from some dump of a station. I own an Oil Company so I kinda know!
This guy is a Nebraska all-star. I recruited for the Army where he lives. Let's just say the bar is low in the Nebraska education system. I had a high school counselor tell me "why bother they are just going to be farmers anyway".
I just run regular on road diesel ⛽️ I'm not going to anything different than I would do if I had a gas. Just like when I had a gas pickup I ran regular and no super it cost enough to run regular say nothing about running high test.
I realize this may not be equivalent to the GM conditioner, but here in Canada I've always used KleenFlo diesel conditioner on my 04 LLY Duramax. 480 000km and going strong.
“Top Tier” is a marketing term… plain and simple. Run fuel sourced from a reputable retailer, run a dose of stanadyne in every tank. Couple bucks worth, not $18.
Just noticed in your video (55 vs 70 MPH MPG test 2021 Chevy Silverado 2500 6.6L V8 Gas) -> ua-cam.com/video/jmB5RQu6FPE/v-deo.html at 11:43 the Sinclair fuel pump you used showed it was Top Tier fuel.....
Good catch and that's part of the problem. The Sinclair uses Top Tier... gas. Not Top Tier diesel. I had to drive over there twice before I filmed this video. Look closer at the video and you'll see a different logo sticker than the Top Tier diesel logo I should in this video. Most people see Top Tier on the pump and assume that means both gas and diesel. It doesn't.
I enjoyed the content on Top Tier Diesel. I'm in Portland Oregon and worked for Costco for 35 years. Retired in 2019. What is interesting to me is that at least in Oregon not all their fuel stations sold diesel but recently Costco is phasing out diesel. just a couple weeks ago I drove to one of their locations that I had bought diesel at previously.....Not anymore. They phased it out there in November. I hate to sound like a conspiracist but.... oh never mind. haha. Garry Young Portland, OR.
When you fill up, why don’t you put a bottle couple bottles of ATF in there do the same thing it’ll clean everything out it’ll even help it start when it’s cold out because ATF at night at a lower temperature and burn all the carbon off
I think that’s BS a diesel fuel a low sulfur these days I agree with Biodiesel I wouldn’t use it , so your going to go 300 miles to fill up your tank and drive back lol
Diesel supplements are subjective in the diesel community. If it’s a feel good thing, then spend the money on fuel additives. I know Ford 6.7 PSD with CP4 fuel pump is recommended. If really cold climates, then some additive help for gelling. I used the reneawable diesel as my new local Union 76 has it. Slight mileage increase, but same price as regular diesel fuel. Just fill up and enjoy the truck no matter if regualar or reneawble. The most important fueling advice with diesel is go to a busy gas station with diesel with high turnover rate for station tank fill. Water is the #1 enemy of diesel.
Hot Shots Secret (EDT) Every Day Treatment is a product that improves fuel quality. My wife filled up her '18 Ram 2500 6.7L Cummins twice without putting in the additive. We went on a camping trip with the truck. The fuel economy was way down. The engine just did not feel right. Stopped for fuel, added the EDT. And about 5 miles later the truck was running like expected again. Cetane number matters! The EDT improves the cetane number. Plus improves lubricity and stability of the fuel.
What do freightliners use? The run everyday all day and engine life and maintenence is most important for return on investment. How do they get away with close to a million miles? Is top tier diesel readily available at Loves, Flying J and the like?
I had a diesel engine in my sailboat that had an injector problem. Took it to a diesel fuel system repair shop. They recommended Stanadyne fuel treatment. It comes in regular or extra lubricity formula. The bottles last for several tankfuls. Every year I use their injector cleaner. My truck is a 2007 Duramax and is still going strong.
In a given area most all diesel coming from the same refinery. Also, Milford has their own dedicated fueling stations with the same size fuel tanks you would see in a large service station. As for additives I highly recommend Power Service or Stanadyne which is much cheaper than the AC Delco.
Here is a UA-cam short showing what to look for at the pump: ua-cam.com/users/shortsP4CS3EmpJKg
Most big brand diesel fuels include conditioner. Conoco specifically says their fuel has 30% more than Toptier.

Top Tier looks more like a marketing initiative than anything. If it was really an issue transport truck diesel engines would need this as well.
Transport diesel engines are like the Cummins, straight six and sturdy. Dirty Max and Power Joke are V-8s rev too high, and have junk aluminum heads.

Does yours rattle like a diesel? A proper running 3.0 is as smooth as a gas motor with no rattle whatsoever.
Runs good! No issues.
Tim I think the take-away here is that it's a good idea to use an additive with your diesel fuel, the ultra-low-sulfur fuel the US has does not lubricate the injection pump & injectors enough.
I have an old GM 6.5 in my truck, one on my boat, and several diesel generator sets. I have been adding about 70 to 1 ratio of two stroke outboard oil to my fuel storage tank. I do not see any harm at all to any of the fuel systems with my Stanadyne , Perkins , and Kubota injection pumps and injectors. Besides, I have a pallet of the 2 stroke lube after the boat shop went belly up.
You're not wrong but at the same time though this has been a standard for a very long time and I'm getting kind of annoyed that oems don't cover injection systems with the fuels available in the markets that they sell them in.

Optilube or hot shots EDT are two great products, 136,893 miles so far on my 2016 Dmax, no problems. By the way, ac delco additive, is a rip off. Stanadyne is the one who manufactures it for GM, I believe. Stanadyne is a great product, but I believe optilube provides the highest lubricity, 2nd goes to hot shots. I would go with hot shots for ease of use packaging, over opti lube. I would also recommend a FASS lift pump for ultra filtration of your fuel.
You're looking way too much into it I run whatever diesel I can get with hot shots secret everyday treatment one oz at Fill up and I have over 250000 miles
You're reading too much into the Top teir reccomendation. It is a quality assurance measurement for marketing purposes. Think of it like the Dexos licensing. Just because an oil doesn't have Dexos on the label doesn't neccesary mean it doesn't mean it won't meet the standard. It just means they didn't pay the license fee and submit it for testing. The key to diesel is to buy from a reputable retailer that turns over fuel often. Additives aren't required.
I have been running Duramax's sense 2005, all I have ever done is put fuel in them and change oil every 8000 miles, never an issue.
@@gleanerman2195 we have fleet of DMAX service trucks in SO CA have been unbelievable. 257k -403k amsoil everything fuel only
No the cetane is higher on top tier diesel. The 3.0 drives WAYYY better (less lag, more power) and gets 4mpg better highway on high cetane fuel.
6.6 l5P is affected as well. But it diminished returns
@@duramaxadventures5832 my tweaked federal emissions standard lb7 runs better on higher cetane bio fuel also gets better mileage.👍
I have a 2019 Chevrolet 3500 with a 6.6L L5P diesel engine with 65,000 miles on it. I use Costco, shell, 76, Chevron, and I have no problems.
I would like to see what the actual sulfur is in the different diesels at different stations. From what everyone says it should be ultra low sulfur per us regulation. Maybe they just didn't update the sticker or maybe it really is low sulfur.
I’ve been happy with HotShot EDT in my Cummins. 99% of the time I fill up at Sinclair, they advertise “Elite diesel” with additive packages containing detergents, lubricity improvers, water separating emulsifiers, higher cetane, and cold flow improvers.
recommend doesn't mean required... no matter how highly they say... Burn whatever you can, like all the rest of us...
Hey Tim, I believe this is just GM stating to use the best fuel possible and that would be Top Tier, to ensure the best performance. Which, if you think about it is a “duh” statement. Of course using better fuel with more detergent to keep injectors clean will be better than not.
That said, I agree that the manual shouldn’t be written the way it was. It instills fear in owners where there shouldn’t be any. We’ve all known for quite some time, even in gas engines, that injectors can get clogged and detergents in the fuel helps to prevent that. In the absence of detergent fuels, fuel injector cleaners can be added to the tank to clean injectors. In the case of GM and the diesel, of course they’re going to only recommend their own cleaner.
I’m planning on buying an AT4 with the LZ0 (drove it and loved it) and I’m not fretting over this in the owners manual.
It’s not a “duh” statement. GM should be informing every customer for this truck that they should use that fuel or get the additive for lower quality diesel fuel.
And they specifically told Tim to use the top tier or add the additive to his fuel for a longer lasting engine.
So many people in love with the GM half ton diesels and they’re really a rip off. Diesel costs more pretty much everywhere, then you gotta pay for your def fluid every so many thousand miles, now if you own a GM truck you better be using the top tier diesel or putting in your additives. Just one more thing to the list to maintain your GM diesel half ton properly. Glad I stayed away from their diesel.
If you can find a new GM V8 missing the cylinder deactivation that would be one to consider but then they have baby fuel tanks so if you tow lots your range is limited.
Just put any diesel fuel swill on your truck and drive it..I use hot shot secret additive and the truck runs fine..325000 miles and going strong
Hey Tim, I worked at a diesel injection service shop for a very short spell right after the ultra low sulfer diesel hit the market. We were a Stanadyne dealer, and we sold gallons of their fuel additive. I don't know if it will meet GM's standards but after running it in a 7.3 it made me a believer. The injector noise quited and the shake the early 7.3's had was minimized.
Running a 7.3 on waste engine oil takes care of those problems also.
The ford 7.3 is hard to kill as long as you take good care of them you know general oil changes and fuel filter you can abuse a crap out of them and they will just keep on running
Costco use Nestlé renewable diesel. Also all the 76 brand in California uses renewable diesel all Arco stations south of Turlock, California uses renewable diesel.
The hot setup is to put 8 oz of 101 into the diesel fuel when you fill it up that will put lubrication back into the fuel and make you have more horsepower and make your fuel pump last longer or use 8 oz of ATF fluid which will help lubricate the injectors and your P4 fuel pump
I get diesel at a gas station with a high turn around and run Hotshots EDT every fuel up. My truck runs gets with EDT, it’s a noticeable difference.
Always use approved injector cleaner that increases cetane level . It lubricants pumps, injectors and upper cylinder wall.
Tim - using an additive is recommended for ALL diesels, especially here in the US where the diesel is of subpar quality to the diesel in Europe, and due to light-duty diesel vehicles also being much more rare here in the US, the diesel tends to sit longer in the tanks at a station.
I use Stanadyne, it’s the highly recommended brand by many professional diesel mechanics. Does come out to about $10/bottle or $3.33/20gallon fill-up.
Thanks for the great content!! 👏🏼👏🏼👏🏼
Are you using it in the Duramax?
@@billoyler8041 no, personally I use it in an ‘05 Jeep 2.8 CRD, more or less same engine as the 2.8 Duramax - but additives are recommended in all diesels due to fluctuations in quality etc…
Stations know how much product they sell and place their orders accordingly. If they only sell 500 gallons a week they don’t order 5000. I do agree with using additive, I like PowerService.
Easy fix is to fill up at the commercial pumps. I don't know if the nozzle fits in a 1/2 ton, but it definitely fits in the HDs.
@@rich7447 not sure about half tons, but it definitely doesn’t fit my Jeep CRD. Tried once lol
My 2008 Dramamax uses Walmart diesel but I also run EDT or Diesel Service treatment.Pretty much in every fuel-up
I don’t believe anything GM says, good luck with that
look up hot shots secret fuel additive 1to 2 ounces per 25 gallons works great
I’ve been using Exxon Mobil Synergy Diesel Efficient fuel. I have a a ram ecodiesel best fuel I could find in my area . Truck gets better mileage 1 to 2 mpg better than the SHEETZ brand I was using
This top tier is a marketing scheme and BS. Worrying over nothing, and making a mountain out if a mole hill IMO. I run mostly Sinclair in my 3.0 and Amsoil fuel additive and truck runs awesome and gets great fuel mileage.
IMO you need to run a good additive. All the good things really needed to lubricate have been removed, repairs are stupid expensive its money well spent and its not as expensive as the GM Products hotshot archoil both good products
I am lucky, there are many stations in my area that serve Top Tier fuel so I plan on using it. If traveling I am okay using whatever I can find, I doubt I will carry additive with me.
That sure is a nice truck but sadly owning any diesel in any of the big 3 are terrible expensive to maintain for average Jo driver there made to work everyday. It's sad because the truck your driving is so refined and awesome to drive normally. But today a diesel will never beat a gas for your pocket book. Def, expensive oil , filters , and timing belt replacement, it's just to expensive of a truck
You clearly have never owned, driven nor worked on the 3.0 Duramax.
Oil isn’t that expensive, it uses timing CHAINS and the oil filter is very cheap. $10.
Ignorance about Diesels is a very American thing.
My 2020 L5P Duramax driven 17500 miles last year and about 1/2 the miles towing an 8K Lb. Travel trailer.
DEF $130 and may be more if towing more. Last year DEF was about 2.5% of fuel use
Oil change - $50 for 2.5 gallons Mobil Delvac Extreme full synthetic 15W40 and $11 filter
Fuel filter - $24 about once a year
Air filter $22
The only additional expense is DEF and a little more for a fuel filter.
Not ‘terrible expensive’ and about the same expense as my ‘17 6.2 Silverado where I run premium when towing for better performance.
Your trucks are Awsome like i said but diesel cost more than gassers today in the long run . And 3.0 diesel has a timing belt that needs maintenance by splitting engine and transmission
@@andyw8082
The belt you are referring to is the oil pump belt. But you are correct that it requires the separation of the engine and transmission at 150,000 miles.
EB Indy didn't tell you the whole story...I guess diesel ignorance is not just an American thing 😏
Maintenance is all I meant sorry fellas
It appears that "Top Tier Diesel" is marketing hype. It appears to be a standard that few suppliers will subscribe to. Probably because that little sticker on the pump will cost the station a fortune.
Mobil Diesel Efficient™ fuel is fully formulated and pre-additized at the terminal, eliminating the need for off-the-shelf additives and saving you time and money. It’s engineered to clean up and keep your fuel injectors clean to deliver the power, reliability and productivity you need from your equipment.
Sounds like GM needs to recommend Exxon/Mobil fuels like they do Mobil 1oil.
anything mobile 1 is the best
Add AMSOIL fuel additive and buy fresh fuel from one of the majors like Shell or ExxonMobil. That's all ive done in my 2020 2500hd. No issues and 75k miles
I got a 2020 2500hd Diesel, have 50k and don't use additives and just go to the main stations or truck stops. I am just amazed at these people dropping 12 bucks per tank on top of the diesel price. Crazy.
Umm nope. This is why I didn't buy a gm. And stayed with Ram. I had no reason to avoid gm and when it came down to it I heard about this top tier shit from a relative.
Well, I have no interest in driving farther than necessary. Once per tank times $19.00 times 1.5 fill ups per week and 52 times a year and the average of me keeping a truck of 10 years comes out to nearly $15,000 extra to have the gm. Haha! No.
I guess if you dont mind taking your vehicle to dealership and leaving it there untill they get to it and wait for the parts to show up for warrenty work if it is in fact a covered repair dont use the proper fuel or additive/buy the way in best interest for yourself to use fuel treatment as recommended/non diesels as well/recommends additive at oil change/guess what/my truck has 450k on it never had a fuel pump or injector!!!!!! You decide what is right for you. Master certified ase techs advice.
Nothing but gimmicks. You'd be much better off just replacing your stock fuel filter with a 2 micron filter from CAT or another brand like that who has actual 2 micron filters. You'll need to change the stock fuel filter housing nipple to fit the larger CAT filter (kits out there), or better yet, replace the entire stock fuel filter housing. Do the same with oil filter housing, or get an oil filter relocation kit. Then you'll have a real defense against fuel contamination instead of buying snake oil every time you fill up. If the manufacturer told you they recommend you piss inside the fuel tank right after each fill-up, you might then draw the line and ignore them? I just draw the line sooner.
Tim I have a 2021 jeep eco diesel. I fill up a Wawa using their diesel fuel and at every fill add hot shot Everyday diesel treatment(EDT). I have seen a difference in fuel economy and I have only 6800 miles and have only had one regen. At the 6500 mile mark I put in extreme diesel treatment helps do everything you are concerned about. A.C. Delco is a gm product that’s why they want you to use it. EDT I use at every fill up and only 1 oz per 20 gallon tank-and the other one every 6000 miles. I swear by this stuff. I hope this helped.FYI… I drove from Orlando Fl to North Georgia one 3/4 tank of fuel and got 26 mpg.
GM has recommended Top Tier fuel in both gas and diesel for years in the owners manual. Dexos oil and top tier fuel were listed in my Camaro ZL1 and my wife’s Chevy Equinox. This is not an issue, just use the best quality fuel and oil you have access to and you will be fine. I don’t use small off the beaten path fuel stations or cheap oils in my vehicles hence why I’m still driving my 2001 Chevy Tahoe with 300k miles on the original engine.
Yep. This same info about Top Tier Fuel was in the owners manual for my 2006 Chevy Cobalt SS/SC
512,000 miles on used fryer oil...First Gen 12valve VE fuel pump Cummins B6...never missed a beat! This sounds like a scam...like gallons of (prop wash) or a cargo bin stretcher or Diesel exhaust fluid!
Reading my Ram Cummins fuel specs. No additives needed. Just use No.2
It’s just marketing. Auto companies partner with other companies to recommend each other. General Motors offer Costco membership discount on their new vehicles that they sell. How do I know? Because I sold GM vehicles for a few years.
Any vehicle with CP4 fuel pumps should use fuel additive in the US and Canada with our shitty fuels.
I use Hot Shots Secret Every Day Diesel additive in my 2019 L5P in summer and their Winter additive in cold weather. Used those products in my 2004 LLY and my 2013 and 2015 TDIs as well. One ounce treats about 20 gallons, costs less than $2.00 per ounce.
I hear it's garbage
You are reading way to much into this! It's just a recommendation telling you to run premium diesel. Never had a problem running any diesel. Just add a fuel conditioner like hot shot secret, power service and so on. If your this worried about it then you don't need to be driving!
I use hot shot secrets diesel additive. It’s at Walmart for $14 a bottle and it treats up to 400 gallons. I did some research on all the additives and hot shots seems to be the best one out there I have noticed a difference in fuel mileage and they also have anti-gel and stiction additive.
That's some good shit. I use it also !
Project Farm did a great UA-cam video on diesel additives. That’s how I ended up using Hot Shots.
I use the Hotshots EDT (Everyday treatment) and use it every fill-up. Tractor supply also sells it.
I use Hotshot Secret EDT or opti-lube products. Both are good products.
ya right. This comment section is full of advertisers I see. Vultures
Sir they are diesel trucks diesel fuel is diesel fuel put fuel in drive change oil and filter and change fuel filter keep up with required maintenance. Once again they are trucks with diesel engines not race cars lol i have owned 4 diesel truck maintenance is key good luck
just an additive pagake is all. and alot more stations carry top tir or premium fuel oil than the list shows.
This reminds me of something Ford did. Years back Ford had a BP logo on the fuel cap and suggested for optimal performance Ford recommends BP fuel.
Fuel where you want and add Hot Shots Secret winter formula for winter Every Day Treat spring summer fall. Call it a day…..but for real, Diesel trucks are becoming too expensive to run daily. I own an Alumiduty and an LBZ and the expense is pushing me more and more to just use them for towing and just run my Tundra for daily because it checks the boxes for less money daily…..
Yup, exactly what the U.S. government has planned.
So that should tell you a whole lot. Cummins just works. Dirty Max and Power Joke not so much.
The word they use is recommended, if it said must use, they want to void warranties. Just a marketing plow to sell delco additive. Since the salesman did not disclose that to you on sale of unit, GM needs to deliver the fuel to you at no cost, at minimum give you the additive at no cost, I doubt they will, easy class action suit.😊
LOL, not wrong fuel, wrong truck. That's a load of dung.
Ah I just get diesel where ever I can. Never cared about "top tier" crap. I run Everyday Diesel treatment from hot shots.
Just buy hot shots additive it’s concentrated and 1 bottle treats up to 400 gallons depending on which one you buy. They have so many different ones to choose from.. don’t waste money on ac delco. Gm wants your money
Costco in lavista NE is going to stop selling diesel effective 9/25/2023.
“Recommended” means it’s not required! Just another marketing gimmick.
I use Hot shot secret every day treatment. Its Just GM being GM. CYA.
i go to my local indian reservation to get fuel and never had problems with duramax
How diesel is diesel other then off road
Or heating it is the same. Citiane rating you have to watch some.
thank god I live in Canada as all our fuels have the conditioner and detergent already added we only have 2 grades and the second is just a high octain based fuel but our government has mandated all fuel be top tire standard so up here GM lies by saying only the 3 offer it as they have a partnership with these service stations but its false all diesel fuels in Canada meet the top tier standards as regulated by the government that is why our Diesel fuel is so expensive
Get the emissions crap off your truck and it will run 100% better.
Just get some brand of cetane booster and move on. Too much talk for no big deal.
I use BP diesel with Optilube XPD additive. TopTier / Dexos approved... just different ways to make GM more money.
Just saw Mobil Enhanced Diesel fuel at a local station. About the same price per gallon with extra detergents added at the terminal to help engine run cleaner and " get 2% better fuel economy" according to Mobil. Sounds like a better alternative than a $17.00 bottle every fill-up or 2.
Living in northern Indiana I fill up with Country Mark "Diesel-ex 4", which they advertise to be full of extra detergents including added cetane and lubricity ratings. Meijer also advertises the same in their diesel fuel. There are plenty of other options of nationwide to buy diesel with added detergents as compared to #2 diesel. I agree that "TopTier" is just a marketing gimmick that Ford and GM are a part of.
Anything Higher Cetane than 42 is good, 50-60 is the best performing and cleanest
There’s probably a separate line at the power service plant with AC Delco bottles getting filled with the exact same stuff🤔. That way GM can charge $18 per tank while PS costs about that for 10 tanks. 😏
Please don't fall for this scam. Ultra Low Sulfur Diesel sold at all stations is perfect for your diesel engine, unless you buy from some dump of a station. I own an Oil Company so I kinda know!
This guy is a Nebraska all-star. I recruited for the Army where he lives. Let's just say the bar is low in the Nebraska education system. I had a high school counselor tell me "why bother they are just going to be farmers anyway".
@@ernestjohnson1807 Maybe so but all those farm boy diesel tractors and combines can use off road diesel fuel
100% Steve. "Top Tier" is just another marketing scam.
I just run regular on road diesel ⛽️ I'm not going to anything different than I would do if I had a gas. Just like when I had a gas pickup I ran regular and no super it cost enough to run regular say nothing about running high test.
I realize this may not be equivalent to the GM conditioner, but here in Canada I've always used KleenFlo diesel conditioner on my 04 LLY Duramax. 480 000km and going strong.
Diesels seem like alot of extra work. Think I will pass
“Top Tier” is a marketing term… plain and simple.
Run fuel sourced from a reputable retailer, run a dose of stanadyne in every tank. Couple bucks worth, not $18.
Just noticed in your video (55 vs 70 MPH MPG test 2021 Chevy Silverado 2500 6.6L V8 Gas) -> ua-cam.com/video/jmB5RQu6FPE/v-deo.html at 11:43 the Sinclair fuel pump you used showed it was Top Tier fuel.....
Good catch and that's part of the problem. The Sinclair uses Top Tier... gas. Not Top Tier diesel. I had to drive over there twice before I filmed this video. Look closer at the video and you'll see a different logo sticker than the Top Tier diesel logo I should in this video.
Most people see Top Tier on the pump and assume that means both gas and diesel. It doesn't.
This is a scam. This show is diesel no matter what you buy if it's red or if it's not.
I enjoyed the content on Top Tier Diesel. I'm in Portland Oregon and worked for Costco for 35 years. Retired in 2019. What is interesting to me is that at least in Oregon not all their fuel stations sold diesel but recently Costco is phasing out diesel. just a couple weeks ago I drove to one of their locations that I had bought diesel at previously.....Not anymore. They phased it out there in November.
I hate to sound like a conspiracist but.... oh never mind. haha.

Hotshot guys put 100,000 miles a year on pickups and do nothing more than fuel, and regular maintenance. This Top Teir stuff is BS!
When you fill up, why don’t you put a bottle couple bottles of ATF in there do the same thing it’ll clean everything out it’ll even help it start when it’s cold out because ATF at night at a lower temperature and burn all the carbon off
You are kidding right?
Buy the additive or sell the P.O.S. truck
I think that’s BS a diesel fuel a low sulfur these days I agree with Biodiesel I wouldn’t use it , so your going to go 300 miles to fill up your tank and drive back lol
Just run optilube or stanadyne and you'll be fine
Dude, you’re reading to much into it. No. 2 diesel is No 2 diesel. It’ll be fine. It’s marketing BS.
Actually it is not just marketing BS as we learned this week when I interviewed an expert.
Diesel supplements are subjective in the diesel community. If it’s a feel good thing, then spend the money on fuel additives. I know Ford 6.7 PSD with CP4 fuel pump is recommended. If really cold climates, then some additive help for gelling.
I used the reneawable diesel as my new local Union 76 has it. Slight mileage increase, but same price as regular diesel fuel. Just fill up and enjoy the truck no matter if regualar or reneawble. The most important fueling advice with diesel is go to a busy gas station with diesel with high turnover rate for station tank fill. Water is the #1 enemy of diesel.
The diesel in the tanks at fuel stations in cold environments already has an anti-gelling additive.
Cenex Roadmaster XL has a great additive package and is much more widely available than top tier
20744 and nothing within 1000 miles.
Lucas oil has Diesel deep clean. $9 a bottle
This is just GM leaving themselves an out for every engine problem. I'm a Costco member near Prescott AZ but it's still impractical if you travel.
What no red or blue diesel? If it's good enough for my tractor or my boat, isn't it good enough for my truck?
Farmer fuel. You can't buy it around me.
Hot Shots Secret (EDT) Every Day Treatment is a product that improves fuel quality. My wife filled up her '18 Ram 2500 6.7L Cummins twice without putting in the additive. We went on a camping trip with the truck. The fuel economy was way down. The engine just did not feel right. Stopped for fuel, added the EDT. And about 5 miles later the truck was running like expected again.
Cetane number matters! The EDT improves the cetane number. Plus improves lubricity and stability of the fuel.
What do freightliners use? The run everyday all day and engine life and maintenence is most important for return on investment. How do they get away with close to a million miles? Is top tier diesel readily available at Loves, Flying J and the like?
Top Tier doesn't exist. I use the same fuel as most semi trucks.
I had a diesel engine in my sailboat that had an injector problem. Took it to a diesel fuel system repair shop. They recommended Stanadyne fuel treatment. It comes in regular or extra lubricity formula. The bottles last for several tankfuls. Every year I use their injector cleaner. My truck is a 2007 Duramax and is still going strong.
Stanadyne is used by most professional diesel injection shops.
Top shelf products
go to truck stop stations for top tier diesel
In a given area most all diesel coming from the same refinery. Also, Milford has their own dedicated fueling stations with the same size fuel tanks you would see in a large service station. As for additives I highly recommend Power Service or Stanadyne which is much cheaper than the AC Delco.
Here's an idea,,, dont effing buy one! The 5.3 fills the need just fine! If thats not enough for your manhood get the 6.2!
That is why I never read the manuals that is BS
GM always looks for wording or a loophole to deny a warranty claim. Bottom line
