ArchoilArchoil AR6500 Diesel Treatment (40 Ounces) - Treats 400 Gallons - Additive for All Diesel Vehicles

Just finished my first bottle of archoil in my 2024 ram 2500. I noticed a slight increase in fuel mileage but I wasn’t doing the double dose to get the gains that’s advertised. But as far as my dpf filter goes, this has been great. I do a lot of in town driving and before I started using archoil my filter percentage would get up to 30% and regen frequently. Ever since I’ve put this in my dpf gauge hasn’t left 0%. Highly recommend

Why did you pick this product vs others?:Since diesel fuel has ZERO additives at the pump, this is a necessity. After extensive on-line research this product always rated at the top. The bottle stores securely and is simple to use with ability to add correct amount every time (1 ounce to 10 gallons fuel). Considering the cost of a new Super Duty, I only use the best products.

First off, im always skeptical of products like this. I have an older Fecon forestry mulcher with the kubota 99hp engine with around 3,800 hours. This thing ALWAYS smoked pretty bad at start up and even a decent amount at idle after it was warm. I added this product in the performance dose amount, only about 6 engine hours ago. Started it up this morning and next to ZERO smoke!!!!! Like how, what, holy crap!!!!! No smoke even when throttling up! I have definitely tried other additives in the past and nothing has ever been this good. I also put this and the fuel system cleaner in my 200hp Rayco C-200 mulcher. Noticed a different smell from the engine a few hours later then it went away. Guessing it was burning stuff off? I just ordered more and also the fuel system cleaner for the smaller Fecon. I definitely didn't get a discount in return for this review. Would have been cool, but I paid full price. FYI- we run these machines wide open 8-10 hours a day. Im blown away. Good idea to replace the fuel filters after doing a fuel system clean too.

Works great been using it on my truck for over a year mileage on my truck is roughly the same but the re-gens are a lot less everything seems to stay cleaner. This along with mobile Centech diesel fuel works great. Don’t even have to plug-in in the winter.

Good product. Fast shipping. Good price

I have a 2025 Chevy (Duramax) and run Hotshot transport. I used the product exactly as instructions prescribed.I honestly didn't see any improvement in fuel mileage. In fact, if anything, a slight drop while loaded.However, I did see a noticeable reduction in DEF consumption!I can't say it helps with improving your mileage, but obviously helps it run cleaner! If you have a higher mileage truck and you use the system cleaner product then this? Yea, I can see how it would get you back on track.Will I use it again? Na! Probably not for a long while

On tank 3, so far regents are down but haven’t seen any change in fuel economy.

I have gained about 1.6 mpg using this and my regens happen less frequently nearly doubling the time between regens. Lubrication of the CP4 pump is critical and this does that. 2015 F250 6.7 PSD
