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 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.
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.
I haul fuel. It all comes out the same tank. Top tier is just a additive we ad when tanking. It’s literally power service fuel treatment that we ad to the Lavista Costco drops and all Kum and Go’s.
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.
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.
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.
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.
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
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 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.
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.
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 have a 2000 Ford 7.3l Power Stroke with 223,00 miles and I add Power Service Diesel Kleen additive. It provides a cetane boost and lubrication for the injectors. I add 1/2 oz. per gallon which is over the minimum recommendation. I avoid bio if at all possible.
@@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.
I just bought a 3.0L and as I read the manual it is recommended not required. Additives are OK in the event you can't access Top Tier fuel which most of us can't.
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.
Apparently Delco stopped making the Fuel System Treatment 10-3014. This according to several GM Parts websites. Also on Amazon it's now like $26 a bottle
Tim, would you please reach out to GM and ask their recommendation for fuel additive in light of no more 10-1034 ac delco product. My local GM dealer confirmed they have stopped production. However, the manual says "do not use any other additive". What gives? Thanks
As other people have mentioned, hot shots edt works really well. I have a cummins and I use it every fill up. One bottle treats 400 gallons, much cheaper than ac Delco
I have a 2021 GMC SIerra with the 3.0L Duramax. The dealer I purchased through pointed this out at time of sale and said to buy top tier diesel at Costco or use Stanadyne 38564 diesel fuel additive if you fill up elsewhere. I buy the 4-packs from Amazon for ~$28.
I have the new 2023 sierra with LZ0 you need the Diesel fuel conditioner. What you showed was for gasoline engines for $17.99. I have to order a box of 6 at a time atthe dealer, and the bottle is $23.99 a bottle. I use it 1 out of every 3 times I fill up. I CAN tell a difference since I am using it.
I have a 2017 Silverado diesel 3500 nonstop problems with the DPF with a turbo leaking oil but as far as the gas, I try to go to the same gas station every time because the tractor trails go there so they’re constantly putting it in and I try not to let the engine idle too muchThat’s not good. I’m gonna check out that additive you put on. I’m gonna see actually GM has had my truck for seven weeks with nonstop problems. That’s another issue. Thank you.
I ran a truck in ND for 2 winters. Used Howess diesel treat in every tank. I think a bottle treats I think 160 gal in winter and costs around 11 to 14 dollars a bottle. Never had a problem geling or anything else. Changed fuel filters every other oil change. Use howes in all my diesels with no troubles. Also got half a gallon per mile better fuel milage. In the truck. Not as good in PU's.
I read the owners manual and actually only fill up with shell top tier diesel fuel, luckilly there are a bunch of top tier gas station where i live in central texas. Also is reccomended to change the engine oil the first 1000 miles for the engine break in and small shavings etc
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.
It doesn’t appear to be a thing in Northern Canada. My dealership doesn’t even have a part number for the additive and said they haven’t had it in stock for almost 2 years.
I remember I bought my 2015 Chev Duramax . I was told by them to add the additive every other fill up or it will effect the performance of the truck or you will sustain engine damage. I did so it was costly . But my truck performed very well . I can’t believe it’s still an issue even after adding def and a performance additive also . Not including the cost of the diesel fuel too . Pricey !
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.
I live close to Costco in La Vista so I use the top tier diesel and I still use archoil 6500. The gm tanks hold 24 gallons you figure you’re typically filling up with 20 gallons it takes 1 ounce per 10 gallons you can run a little richer if you want. The bottles come in 40 ounce containers so you can get roughly 20 fills with one bottle for $45. The stuff works I’ve noticed less re gens and better mileage
Thanks for your video. I was first introduced to "top tier" when I purchased a Hyundai Palisade in 2019. I was not aware it was even available at all for diesel. I own a Ram diesel and plan to look further into this.
I always read the manual, but I do not necessarily follow it. I change the oil every 5k miles not every 10k. I replace the filter every other oil change.
I own a Chevy Cruze sedan. I buy a 32 oz bottle of Power Service and pour 1/4 a bottle in the tank at every fuel up. It adds about $2 to the cost of every tank.
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.
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.
Quarles Fleet Fueling stations have premium 47 cetane diesel that is filtered at the pump. The problem is that it is commercial purchase only. I run it in 3 trucks for my business but it is about 30 cents a gallon more than standard 40 cetane stuff.
I watch a video that Andre did for TFLTruck. They use Sinclair diesel for their Ram 2500. He said that it contains additives in the gasoline and the diesel to help the engine and the components to stay clean.
Tim, there’s no top tier diesel in New Mexico so I try to fill up at a Love’s truck stop but otherwise I use Phillips or Chevron Diesel. I have purchased a diesel additive from a company called Optilube. I have both a cetane booster and an antigel but I haven’t used either. I have been getting on the average 29 mpg so around 600 miles per tankful. Paid $3.95/gal today at Phillips. My last distance between regens was 501 miles according to my BANKS IDASH.
@Timothy Roemer : WOW... enjoy your "cheap" diesel fuel price! Here, today 2/20/2023, in Western New York State, on-highway diesel at the pump is STILL $4.89 - $5.59/gal, all within a 50-mile radius. Absolutely disgusting. And... it's NOT because of the taxes that it's that high either, despite what so many ignorant folks seem to believe. It's just a total ripoff, based upon corporate GREED.
@@turbodiesel4709 New Mexico is a big fossil fuel extraction/production state. Most of the tax revenue generated from this industry funds the state. I totally agree about the corporate greed factor. The fossil fuel companies raked in 200 billion in profit last year. In a capitalistic economy that we live in profit is first. When profits are down the first thing a company does is layoff part of the workforce to keep the investors happy. Yep it’s disgusting.
I had the same truck but a 2020 MY, just used regular diesel, never knew about or saw top tier diesel juice for sale in my area, I will say when it came to DEF fluid, I always drove to a truck stop and fill up and would never buy a container of DEF fluid in a box.
I always added some Power Service Diesel Kleen when filling up my 2.0 TDI. Runs like a champ and almost at 200k miles. Helps lube the fuel pump and system. A little extra $ for peace of mind.
I used Stanadyne additive in my 2006 3500 Duramax every tank full. On my new 2023 3500 HD Duramax I'm using HotShot EDT at the 2oz treatment at every fill. I feel both are the best choice. I buy HotShot EDT direct as they give a mil pricing.
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
My 2018 GMC Van has a 2.8 Duramax. The manual says use #2. And I do. It mentions "premium diesel fuel" but doesn't say what it is. However it does discourage B-20. I stick with the rules. #2 always, Penzoil Euro Platinum Synthetic Dexos 2 and Archoil AR6200 at every fill up. Pretty happy with that motor and its performance. Beats the heck out of my old van with the Vortec 350. gas. In my area, fuel comes down from Portland oregon via pipeline. #2 is #2, doesn't matter where you buy it. Chevron for example says right on their pump that they do nothing with "additives" on #2. don't get too hyped up over who's #2 you use.
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.
Even the GMC HD Diesel engine supplement calls for this top tier fuel and I run a 2020 that has 97,000 miles on diesel from all over the place and it's been fine. I do try and use fuel from name brand stations. I also run everyday diesel additives and feel my MPGs have improved. I have 35" tires and get around 20 on the highway and 15 around town.
It has been over 40 years since I looked at refineries - I only inspected independent refineries. If you have an independent refinery they will have all the grades of gasoline and then each brand will have a 500 gallon or so tank of that brand's "secret sauce" that they add a little to the tanker and then it mixes in down the highway and installed. I cannot imagine that Top Tier is anything but a marketing thing. I just looked up for California and did not see any Top Tier diesel. I do occasionally add some additives, especially in the winter, to aid in quicker starting. Unfortunately I do not remember what the refineries did for diesel.
I live in Canada just over the border in a small town and your video got me curious to do a search. I have one station 3 minutes away and 3 more within 15 minutes. All are shell stations with reg and premium diesel. Big price difference though
I live within a few miles of the LaVista Costco with Top Fuel, I've been filling there as my primary station since acquiring our truck, we'll see if it makes a difference on our 2021 3500 Silverado.
Costco adds up to 5% biodiesel to their fuel as a lubricity additive. Studies have shown that biodiesel is one of the best additives for improving fuel lubricity for protecting injection pumps and injectors. I try full up at Costco fuel stations because I have two convenient locations near where I live.
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.
I’ve been a Lucas user for over 20 years in gas and currently my 6.7 Powerstroke. With 111,000 miles and I can’t testify for the evidence inside the engine but I know it helps mileage so injectors must like it.
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.
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.
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.
All you need is a good quality Diesel fuel supplier and a good lubricity additive for your fuel such as Hot Shots EDT or Archoil AR6300. All the ULSD diesel fuel is pretty much the same if you're getting it from a reputable high-volume fuel retailer (I personally ONLY buy diesel at high-volume retailers like Truck Stops). Don't read too much into the Top Tier branded diesel crap. As long as you have clean fuel & a decent lubricity additive, you'll keep your engine, fuel pump, injectors, and emissions system happy. Also try to keep Biodiesel content to 11% or less. It's been shown that higher (20%) Biodiesel content has a tendency to clog DPFs quicker
I use Howes diesel additive in all of our diesel trucks. It is only a few ounces per fillup and pays for itself. You can tell the difference and just use whatever diesel is available or cheapest. Injectors stay clean. I switch to the winter version when temps go below 15.
It sounds like GM has a marketing deal with Top Tier. I recommend Hot Shots Secret fuel additive. It is not expensive, and it works great! One additive that does it all for you and is a quality product. I use it in my diesel on every fuel up. One bottle goes a long way, 400 gallons i think. Use a good brand name fuel (just don't get the red stuff).
I have a 2004 Chevy LB7 Duramax and have used Amsoil Diesel fuel conditioner and cetane booster without any problems , other than all early Duramax's had to have all 8 injectors replaced at 100 K due to a bad Bosch fuel injectors ,after going with after market injectors I have never had a issue with the truck !
I have been running hot shots secret EDT or every day diesel treat in my 2019 F250 with a 6.7 since I bought it great stuff I only need to add 1 ounce per 25 gallons. I have a 60 gallon tank I run down to about the quarter tank mark add 2 ounces fill it up and ride.
Thanks for the video! I’m a new LZ0 owner with just about 5k miles on it and I’ve been wondering this top-tier business since day 1. Glad for this comment section too. It’s great to hear what other owners are doing.
I am also how many miles are you getting for a fill up. Only reason I asked is cause when I purchased mine the dealership filled it up and I had 550 miles until empty. I been filled it up and got 380 miles until empty.
@Johnny Cevallos we don't have BP in my area. The salesman used chevron at the time of my purchase. It was 560 miles I may need to try them and see. Thanks for the info
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.
I use AMSOIL All-In-One diesel fuel additive in my Duramax at every fill up. Their 8oz bottle is perfect for a 20-26 gallon tank. I have been using it for over 5 years without a single problem. My son bought a 2021 Silverado 1500 with the 3.0L Duramax, and has been using a bottle with every tank of fuel, and also has zero problems. This stuff is proven and is the best all around diesel fuel additive out there!
I live in California and more than half of gas stations have that bio mass diesel. I avoid them because the exhaust is very stinky with renewable diesel. I use Hotshot secret every 3 months or so. 2 cummins trucks 1 has 400k miles 2nd has 270k and both have all original fuel system.
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
Buy the conditioner from amsoil. you get 6 8 oz bottles. for roughly $50. That's $8.30 per bottle. One bottle is about 1 ounce short of what you need. But one bottle is should be more efficient that none.
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.
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.
Just use a quality diesel fuel additive like HotShots or OptiLube in EVERY tank and replace fuel filter every 3rd oil change, and your injection/emissions systems will perform great for the long term. Top tier just means it has extra detergents/lubricants, which you can get from any number of high quality additives, not just AC Delco.
Our Costco (that sells Diesel many do not) is 25 miles away from our home in the Sierra Foothills. After learning this about Top Tier Diesel I will try to make Costco my go to fuel stop. I added a 60 gallon Aux Fuel Tank by RDS to my 2021 Chevrolet 3500 HD right after I purchased it. Having this tank gives me many more options when fueling as the range of the truck is now over 1500 miles (not towing heavy) and 900 miles (while towing 12K +). I have also been using Archoil AR6500 (one ounce per 10 gallons of diesel). The truck idles smoother and does less regenerations with the Archoil additive. I have a Banks iDash so I can see the soot load and regen status.
The 6.0 Ford had all type of issues with injectors and the pump. I once had a lengthy conversation with a representative from Ford's Powerstroke division. He told me that California had 90% less problems with the 6.0 then the rest of the country. Only fuel that is refined in California can be sold there. The diesel there at the time had a higher cetane rating then the rest of the country, plus an additional cleaners. This is why Ford sold a diesel fuel additive. We started recommending it to all of our customers. Your milage my very.
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.
Are you were looking at the ram information page? It did say something about a higher cetane rating. They did not say specifically top-tier but again it would run better with the higher rating
As a 3.0 owner fuel makes a HUGE difference. I've only used top tier once because it was not available in my area and I got better MPG way less injector knock the engine was smoother and the throttle was more responsive. Looking at the OBD2 data I was generating more torque before downshift which is where I was getting the increased MPG.
I use mostly top tier diesel because there is a Costco diesel warehouse with 3 miles where I work. I took a trip to the Gulf Coast of Texas. There wasn't top tier diesel available for the trip. I haven't been able to tell the difference.
The ford proving ground in Yucca AZ/ now owned by Ram Dodge/ has a BIG fueling area! I would think that all testing grounds would be the same! It would be stupid not having their own fuel tanks !
This keeps popping up in my suggestions. For the most part diesel fuel is a commodity based product. Just like gasoline, specific additives are injected at the terminal or "rack" based on the time of year (winter/summer) and the brand specific additives and the amount of the additive. Some additives are more expensive than others. Simple thing to remember more for diesel than gasoline. Get you fuel from a station or supplier that turns over a lot of fuel quickly. Stay away from small locations and unbranded stations. Make sure you maintain your fuel filter and change as required. Don't go cheap on your filters or you will pay dearly.
If you could, I would get a tank at your house and get fuel drops. You will save money, it’s more convenient and you can pick what fuel you want. I hate doing it, but I use bio when it’s warm, but I switch to #2 in the winter time. I can also get 90/10, 80/20, or 70/30 splits of #2/#1 for when it’s really cold.
Great video post...It would be great if you could follow this up further with your engineering contacts inside Chevy/GMC. Your video posts have been very educational...thanks for that!! This is an important concern about a great engine. I am looking for a truck to buy later this year for pulling a 23' RV out of Colorado. The Duramax (Chevy or GMC) was at the top of the list until this video. I don't want to have to add a $15+ fuel additive to an already very expensive fuel. I hope you can explore this further!! Thanks!
Low sulfur diesel. I run an additive in every tank! Don’t want low cetane. I run either Hot Shots or Archoil. I have an 05 Excursion 6.0 with 192,000 miles. No issues at all! Keep those injectors happy!! 😎🇺🇸
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?
Another reason why I ordered a F350 with the 7.3L gasser instead of a diesel. I want the extra power but won't use all of the capabilities of a diesel and don't want the diesel headaches or cost of maintenance/operation.
I read an article about using lower quality diesel in Eastern European countries, it said that Mercedes Benz recommended there customers put approximately 20 ml of two stroke oil in a tank of diesel for the reasons you outlined
I have a costco 4 miles away and never knew their fuel was "better". I guess I need to give that a shot. I just hate the line that is almost always long at the pump.
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. 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.
Thank you for this info, I have a 2020 6.6 and never knew about the top tier recommendations but definitely will be researching this further
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.
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.
Why not. It will not hurt anything.
There you go! Off base info, I use the same. No problems, hot shot makes diesel a premium diesel.
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.
I haul fuel. It all comes out the same tank. Top tier is just a additive we ad when tanking. It’s literally power service fuel treatment that we ad to the Lavista Costco drops and all Kum and Go’s.
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.👍
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.
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.
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.
I will do the same!
whatever. Go run your scam elsewhere
Have been using regular diesel at every fill up on my '21 3.0L in my Silverado. Never noticed any decrease in performance
It’s like eating McDonald’s everyday, won’t notice it until you’re 40 and have heart disease
@@cybertrk Sadly, that is a good analogy.
@@cybertrk i guess i'm good for another 40 years! Lol! Only ate at mcdonalds one time in 15 years. 🤣🤣
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.
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
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 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
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.
@@skunkjobb Lubricity in petroleum comes mainly from sulfur. 3000 ppm in the days before. 15ppm now.
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
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.
All Costo Fuel is indeed Top Tier including Diesel.
I have a 2000 Ford 7.3l Power Stroke with 223,00 miles and I add Power Service Diesel Kleen additive. It provides a cetane boost and lubrication for the injectors. I add 1/2 oz. per gallon which is over the minimum recommendation. I avoid bio if at all possible.
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.
@@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.
@geraldkoth654 you have no clue what you're talking about
...not how engine design, emissions management and expected maintenance schedules work re comparing light duty to "transport" trucks.
power joke 🤣🤣🤣🤣@@geraldkoth654
I just bought a 3.0L and as I read the manual it is recommended not required. Additives are OK in the event you can't access Top Tier fuel which most of us can't.
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.
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.
Apparently Delco stopped making the Fuel System Treatment 10-3014. This according to several GM Parts websites. Also on Amazon it's now like $26 a bottle
Tim, would you please reach out to GM and ask their recommendation for fuel additive in light of no more 10-1034 ac delco product. My local GM dealer confirmed they have stopped production. However, the manual says "do not use any other additive". What gives? Thanks
As other people have mentioned, hot shots edt works really well. I have a cummins and I use it every fill up. One bottle treats 400 gallons, much cheaper than ac Delco
I have a 2021 GMC SIerra with the 3.0L Duramax. The dealer I purchased through pointed this out at time of sale and said to buy top tier diesel at Costco or use Stanadyne 38564 diesel fuel additive if you fill up elsewhere. I buy the 4-packs from Amazon for ~$28.
I have the new 2023 sierra with LZ0 you need the Diesel fuel conditioner. What you showed was for gasoline engines for $17.99. I have to order a box of 6 at a time atthe dealer, and the bottle is $23.99 a bottle. I use it 1 out of every 3 times I fill up. I CAN tell a difference since I am using it.
I have a 2017 Silverado diesel 3500 nonstop problems with the DPF with a turbo leaking oil but as far as the gas, I try to go to the same gas station every time because the tractor trails go there so they’re constantly putting it in and I try not to let the engine idle too muchThat’s not good. I’m gonna check out that additive you put on. I’m gonna see actually GM has had my truck for seven weeks with nonstop problems. That’s another issue. Thank you.
I ran a truck in ND for 2 winters. Used Howess diesel treat in every tank. I think a bottle treats I think 160 gal in winter and costs around 11 to 14 dollars a bottle. Never had a problem geling or anything else. Changed fuel filters every other oil change. Use howes in all my diesels with no troubles. Also got half a gallon per mile better fuel milage. In the truck. Not as good in PU's.
I read the owners manual and actually only fill up with shell top tier diesel fuel, luckilly there are a bunch of top tier gas station where i live in central texas. Also is reccomended to change the engine oil the first 1000 miles for the engine break in and small shavings etc
Top Tier gas or Top Tier diesel? Different things.
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.
It doesn’t appear to be a thing in Northern Canada. My dealership doesn’t even have a part number for the additive and said they haven’t had it in stock for almost 2 years.
I remember I bought my 2015 Chev Duramax . I was told by them to add the additive every other fill up or it will effect the performance of the truck or you will sustain engine damage. I did so it was costly . But my truck performed very well . I can’t believe it’s still an issue even after adding def and a performance additive also . Not including the cost of the diesel fuel too . Pricey !
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
I live close to Costco in La Vista so I use the top tier diesel and I still use archoil 6500. The gm tanks hold 24 gallons you figure you’re typically filling up with 20 gallons it takes 1 ounce per 10 gallons you can run a little richer if you want. The bottles come in 40 ounce containers so you can get roughly 20 fills with one bottle for $45. The stuff works I’ve noticed less re gens and better mileage
look up hot shots secret fuel additive 1to 2 ounces per 25 gallons works great
Thanks for your video. I was first introduced to "top tier" when I purchased a Hyundai Palisade in 2019. I was not aware it was even available at all for diesel. I own a Ram diesel and plan to look further into this.
I always read the manual, but I do not necessarily follow it. I change the oil every 5k miles not every 10k. I replace the filter every other oil change.
I own a Chevy Cruze sedan. I buy a 32 oz bottle of Power Service and pour 1/4 a bottle in the tank at every fuel up. It adds about $2 to the cost of every tank.
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.
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.
Quarles Fleet Fueling stations have premium 47 cetane diesel that is filtered at the pump. The problem is that it is commercial purchase only. I run it in 3 trucks for my business but it is about 30 cents a gallon more than standard 40 cetane stuff.
I watch a video that Andre did for TFLTruck. They use Sinclair diesel for their Ram 2500. He said that it contains additives in the gasoline and the diesel to help the engine and the components to stay clean.
Tim, there’s no top tier diesel in New Mexico so I try to fill up at a Love’s truck stop but otherwise I use Phillips or Chevron Diesel. I have purchased a diesel additive from a company called Optilube. I have both a cetane booster and an antigel but I haven’t used either. I have been getting on the average 29 mpg so around 600 miles per tankful. Paid $3.95/gal today at Phillips. My last distance between regens was 501 miles according to my BANKS IDASH.
@Timothy Roemer : WOW... enjoy your "cheap" diesel fuel price!
Here, today 2/20/2023, in Western New York State, on-highway diesel at the pump is STILL $4.89 - $5.59/gal, all within a 50-mile radius. Absolutely disgusting.
And... it's NOT because of the taxes that it's that high either, despite what so many ignorant folks seem to believe. It's just a total ripoff, based upon corporate GREED.
@@turbodiesel4709 New Mexico is a big fossil fuel extraction/production state. Most of the tax revenue generated from this industry funds the state. I totally agree about the corporate greed factor. The fossil fuel companies raked in 200 billion in profit last year. In a capitalistic economy that we live in profit is first. When profits are down the first thing a company does is layoff part of the workforce to keep the investors happy. Yep it’s disgusting.
I had the same truck but a 2020 MY, just used regular diesel, never knew about or saw top tier diesel juice for sale in my area, I will say when it came to DEF fluid, I always drove to a truck stop and fill up and would never buy a container of DEF fluid in a box.
I always added some Power Service Diesel Kleen when filling up my 2.0 TDI. Runs like a champ and almost at 200k miles. Helps lube the fuel pump and system. A little extra $ for peace of mind.
I used Stanadyne additive in my 2006 3500 Duramax every tank full. On my new 2023 3500 HD Duramax I'm using HotShot EDT at the 2oz treatment at every fill. I feel both are the best choice. I buy HotShot EDT direct as they give a mil pricing.
I drove my ‘21 3 L pulling a 6000 lb travel trailer a bit over 3000 miles last summer using truck stop fuel and DEF. No problems at all.
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
My 2018 GMC Van has a 2.8 Duramax. The manual says use #2. And I do. It mentions "premium diesel fuel" but doesn't say what it is. However it does discourage B-20. I stick with the rules. #2 always, Penzoil Euro Platinum Synthetic Dexos 2 and Archoil AR6200 at every fill up. Pretty happy with that motor and its performance. Beats the heck out of my old van with the Vortec 350. gas.
In my area, fuel comes down from Portland oregon via pipeline. #2 is #2, doesn't matter where you buy it. Chevron for example says right on their pump that they do nothing with "additives" on #2. don't get too hyped up over who's #2 you use.
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
I think the most important thing is to keep up on your fuel filter changes with quality filters......
Even the GMC HD Diesel engine supplement calls for this top tier fuel and I run a 2020 that has 97,000 miles on diesel from all over the place and it's been fine. I do try and use fuel from name brand stations. I also run everyday diesel additives and feel my MPGs have improved. I have 35" tires and get around 20 on the highway and 15 around town.
Been around diesels for 40 plus years. BP diesel is about the best if it’s available where your at.
It has been over 40 years since I looked at refineries - I only inspected independent refineries. If you have an independent refinery they will have all the grades of gasoline and then each brand will have a 500 gallon or so tank of that brand's "secret sauce" that they add a little to the tanker and then it mixes in down the highway and installed. I cannot imagine that Top Tier is anything but a marketing thing. I just looked up for California and did not see any Top Tier diesel. I do occasionally add some additives, especially in the winter, to aid in quicker starting. Unfortunately I do not remember what the refineries did for diesel.
I live in Canada just over the border in a small town and your video got me curious to do a search. I have one station 3 minutes away and 3 more within 15 minutes. All are shell stations with reg and premium diesel. Big price difference though
I live within a few miles of the LaVista Costco with Top Fuel, I've been filling there as my primary station since acquiring our truck, we'll see if it makes a difference on our 2021 3500 Silverado.
My 2008 Dramamax uses Walmart diesel but I also run EDT or Diesel Service treatment.Pretty much in every fuel-up
Costco adds up to 5% biodiesel to their fuel as a lubricity additive. Studies have shown that biodiesel is one of the best additives for improving fuel lubricity for protecting injection pumps and injectors. I try full up at Costco fuel stations because I have two convenient locations near where I live.
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
I have been using Lucas in my 2022 6.6 duramax. Haven’t had any issues clocking in around 120,000 so far.
I’ve been a Lucas user for over 20 years in gas and currently my 6.7 Powerstroke. With 111,000 miles and I can’t testify for the evidence inside the engine but I know it helps mileage so injectors must like it.
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.
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
Hot Shots secret EDT is bliss.
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.
I use this also in my big truck. It improved much fuel milage and it definitely funds better?
All you need is a good quality Diesel fuel supplier and a good lubricity additive for your fuel such as Hot Shots EDT or Archoil AR6300. All the ULSD diesel fuel is pretty much the same if you're getting it from a reputable high-volume fuel retailer (I personally ONLY buy diesel at high-volume retailers like Truck Stops). Don't read too much into the Top Tier branded diesel crap. As long as you have clean fuel & a decent lubricity additive, you'll keep your engine, fuel pump, injectors, and emissions system happy. Also try to keep Biodiesel content to 11% or less. It's been shown that higher (20%) Biodiesel content has a tendency to clog DPFs quicker
Stanadyne has been around for some time. $40 for 64 ounces… you need 6.5 ounce per tank… worth the extra $4 per tank. It works.
I use Howes diesel additive in all of our diesel trucks. It is only a few ounces per fillup and pays for itself. You can tell the difference and just use whatever diesel is available or cheapest. Injectors stay clean. I switch to the winter version when temps go below 15.
That plus 4 oz of 2 stroke oil . 6.7 2012 approaching 650.000 km running strong all original accept some garbage wink. Wink
Wow. This is 100% correct and no other reviews have mentioned this!
It sounds like GM has a marketing deal with Top Tier. I recommend Hot Shots Secret fuel additive. It is not expensive, and it works great! One additive that does it all for you and is a quality product. I use it in my diesel on every fuel up. One bottle goes a long way, 400 gallons i think. Use a good brand name fuel (just don't get the red stuff).
I have a 2004 Chevy LB7 Duramax and have used Amsoil Diesel fuel conditioner and cetane booster without any problems , other than all early Duramax's had to have all 8 injectors replaced at 100 K due to a bad Bosch fuel injectors ,after going with after market injectors I have never had a issue with the truck !
I have been running hot shots secret EDT or every day diesel treat in my 2019 F250 with a 6.7 since I bought it great stuff I only need to add 1 ounce per 25 gallons. I have a 60 gallon tank I run down to about the quarter tank mark add 2 ounces fill it up and ride.
Thanks for the video! I’m a new LZ0 owner with just about 5k miles on it and I’ve been wondering this top-tier business since day 1. Glad for this comment section too. It’s great to hear what other owners are doing.
I am also how many miles are you getting for a fill up. Only reason I asked is cause when I purchased mine the dealership filled it up and I had 550 miles until empty. I been filled it up and got 380 miles until empty.
@@bigwes318 just filled up. Range says 566.
@Johnny Cevallos you mind me asking what brand you using and price
@@bigwes318 this was BP Diesel at $4.10/g
@Johnny Cevallos we don't have BP in my area. The salesman used chevron at the time of my purchase. It was 560 miles I may need to try them and see. Thanks for the info
I have a 23 GMC sierra denali LZ0. What fuel brand do you all recommend.
I use BP diesel with Optilube XPD additive. TopTier / Dexos approved... just different ways to make GM more money.
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.
I use AMSOIL All-In-One diesel fuel additive in my Duramax at every fill up. Their 8oz bottle is perfect for a 20-26 gallon tank. I have been using it for over 5 years without a single problem. My son bought a 2021 Silverado 1500 with the 3.0L Duramax, and has been using a bottle with every tank of fuel, and also has zero problems. This stuff is proven and is the best all around diesel fuel additive out there!
Power Service.
I live in California and more than half of gas stations have that bio mass diesel. I avoid them because the exhaust is very stinky with renewable diesel. I use Hotshot secret every 3 months or so. 2 cummins trucks 1 has 400k miles 2nd has 270k and both have all original fuel system.
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
Buy the conditioner from amsoil. you get 6 8 oz bottles. for roughly $50. That's $8.30 per bottle. One bottle is about 1 ounce short of what you need. But one bottle is should be more efficient that none.
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
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 use both Costco and Sam’s club diesel in my ecoD. Funny thing is I get less mpg when I use Costco gas. Never fails.
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.
Just use a quality diesel fuel additive like HotShots or OptiLube in EVERY tank and replace fuel filter every 3rd oil change, and your injection/emissions systems will perform great for the long term. Top tier just means it has extra detergents/lubricants, which you can get from any number of high quality additives, not just AC Delco.
Adaptive really isn’t for the fuel itself. It’s for the fuel pumps to keep them lubricated really well.
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
Our Costco (that sells Diesel many do not) is 25 miles away from our home in the Sierra Foothills. After learning this about Top Tier Diesel I will try to make Costco my go to fuel stop. I added a 60 gallon Aux Fuel Tank by RDS to my 2021 Chevrolet 3500 HD right after I purchased it. Having this tank gives me many more options when fueling as the range of the truck is now over 1500 miles (not towing heavy) and 900 miles (while towing 12K +). I have also been using Archoil AR6500 (one ounce per 10 gallons of diesel). The truck idles smoother and does less regenerations with the Archoil additive. I have a Banks iDash so I can see the soot load and regen status.
The 6.0 Ford had all type of issues with injectors and the pump. I once had a lengthy conversation with a representative from Ford's Powerstroke division. He told me that California had 90% less problems with the 6.0 then the rest of the country. Only fuel that is refined in California can be sold there. The diesel there at the time had a higher cetane rating then the rest of the country, plus an additional cleaners.
This is why Ford sold a diesel fuel additive. We started recommending it to all of our customers. Your milage my very.
When I go to that site I see pumps all over my city like everywhere. And I’m in a small city Corpus Christi
Gas pumps or diesel pumps?
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.
Are you were looking at the ram information page? It did say something about a higher cetane rating. They did not say specifically top-tier but again it would run better with the higher rating
As a 3.0 owner fuel makes a HUGE difference. I've only used top tier once because it was not available in my area and I got better MPG way less injector knock the engine was smoother and the throttle was more responsive. Looking at the OBD2 data I was generating more torque before downshift which is where I was getting the increased MPG.
I use mostly top tier diesel because there is a Costco diesel warehouse with 3 miles where I work. I took a trip to the Gulf Coast of Texas. There wasn't top tier diesel available for the trip. I haven't been able to tell the difference.
Full of schitt
@@2cthetruth data doesn't lie
@@duramaxadventures5832 unless it's made up to promote sales...you goober
The ford proving ground in Yucca AZ/ now owned by Ram Dodge/ has a BIG fueling area! I would think that all testing grounds would be the same! It would be stupid not having their own fuel tanks !
This keeps popping up in my suggestions. For the most part diesel fuel is a commodity based product. Just like gasoline, specific additives are injected at the terminal or "rack" based on the time of year (winter/summer) and the brand specific additives and the amount of the additive. Some additives are more expensive than others. Simple thing to remember more for diesel than gasoline. Get you fuel from a station or supplier that turns over a lot of fuel quickly. Stay away from small locations and unbranded stations. Make sure you maintain your fuel filter and change as required. Don't go cheap on your filters or you will pay dearly.
If you could, I would get a tank at your house and get fuel drops. You will save money, it’s more convenient and you can pick what fuel you want. I hate doing it, but I use bio when it’s warm, but I switch to #2 in the winter time. I can also get 90/10, 80/20, or 70/30 splits of #2/#1 for when it’s really cold.
Great video post...It would be great if you could follow this up further with your engineering contacts inside Chevy/GMC. Your video posts have been very educational...thanks for that!! This is an important concern about a great engine. I am looking for a truck to buy later this year for pulling a 23' RV out of Colorado. The Duramax (Chevy or GMC) was at the top of the list until this video. I don't want to have to add a $15+ fuel additive to an already very expensive fuel.
I hope you can explore this further!! Thanks!
The GM response I showed is from GM engineering. They are sticking to their statement.
Low sulfur diesel. I run an additive in every tank! Don’t want low cetane. I run either Hot Shots or Archoil. I have an 05 Excursion 6.0 with 192,000 miles. No issues at all! Keep those injectors happy!! 😎🇺🇸
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.
Always use approved injector cleaner that increases cetane level . It lubricants pumps, injectors and upper cylinder wall.
I’m in Texas, and I just checked all Top Tier diesel fuels within 1000 miles of me, and there are ZERO locations where I can purchase this fuel.
Another reason why I ordered a F350 with the 7.3L gasser instead of a diesel. I want the extra power but won't use all of the capabilities of a diesel and don't want the diesel headaches or cost of maintenance/operation.
Well to be fair as it relates to this video they still recommend Top Tier fuel whether it's for gasoline engines or diesel.
I read an article about using lower quality diesel in Eastern European countries, it said that Mercedes Benz recommended there customers put approximately 20 ml of two stroke oil in a tank of diesel for the reasons you outlined
You generally only add a couple ounces per tank so that 18 dollar container should probably last 6 to 10 fill ups most likely
I have a costco 4 miles away and never knew their fuel was "better". I guess I need to give that a shot. I just hate the line that is almost always long at the pump.
