Archoil AR6500 Diesel Treatment (40.6oz) Two Pack - Treats 800 Gallons - Additive for All Diesel Vehicles

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.

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.

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

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

Good product. Fast shipping. Good price

Fantastic diesel treatment. Run it in every tank in my 6.7 powerstroke. Check out the chemical breakdown reviews on YouTube, you’ll see this is a very proven additive.

I have used this additive in my 12 year old Jeep with 162,000 miles on it and have noticed a 2 mile per gallon increase in mileage . It’s the first time an additive have done what the advertising promoted .

Really helps smooth out the idle and produce less soot in my 2000 Excursion. Get the oil additive too. MPG improved by a few miles which is pretty insignificant to me but how smooth the truck runs is quite dramatic. Put this in your truck, you won't regret it
