Archoil AR6500 Diesel Treatment (40 oz) Two Pack - Treats 800 Gallons, Diesel Fuel Additive - Lubricity Improver, Injector Cleaner, DPF & Turbo Deposit Control, Cetane Booster

Great results , have been using for about a year and a half on our Baby Diesel 4.0 Chevy 1500 pick up. Highest mileage has been 41.4 per gallon but around 30 to 31 average driving city and highway. Fewer and shorter regenerations. Very satisfied with the product would recommend.

I order these every couple of months for my diesel, and at this point, it’s a staple for me. If you’re running a modern diesel, this is something you should seriously consider. After about 50,000 miles of consistent use, I’ve had zero issues. The truck is still running strong, holding higher MPG numbers, and everything feels smooth and consistent. One thing that really stood out to me—my fuel filters have come out clean, which says a lot about how well this is doing its job. It’s easy to use, mixes well, and doesn’t require any extra hassle. Just add it and go. Overall, this has proven itself over time for me. Reliable, effective, and something I’ll keep using long-term.

I suspect my Audi 3.0 TDI had a clogged cat some 5 years after a DPF delete back in 2019. MPG was down and it felt like it was also down on power. Sometimes the "Italian Tune-up" (high rev driving) would briefly help by blowing a lot of crap out the back, but it would go back to reduced after a day or two. I had been using the Hotshots Every Day in each fill-up, which may have slowed this issue down but it still happened. I also tried Opti-Lube XPD for a few months. Not much, if any, improvement. I do suspect they helped improve cetane values, but idk what else. If I had a good run, I was getting ~560 miles per tank. After some YouTube videos, I decided to try Archoil. I didn't notice anything for a couple fill-ups, but after about 1-1.5 months, I started to notice some slight improvements in mileage to/from work and some other trips. It was getting hard to hit 30 mpg on the way to work, whereas I started hitting 31-32, even with significant traffic. After 2 months, there has been a definite improvement. I'm currently seeing 33+ mpg on the way to work (same conditions as before) and reaching closer to the 38 mpg EPA advertised on my way home. I've also hit 42 mpg coming home from a friends' house, whereas before it was struggling to hit 39. Power feels like it has returned to expected levels compared to the previous treatments. My range is now reporting >600 miles per tank, even dealing with some stop and go traffic. For the results, price, and ease of applying into the tank, I highly recommend using it and I intend to continue using this from hereon out.

So fair its working very well helps with easier starts and smother running very good product

Great product and increase’s mileage

I use this in 2017 ford Deisel and works great.

Best diesel treatment I've ever used. Just wish they made it large enough for semi trucks. It costs a fortune to run through my semi. I buy 4 bottles of the cleaner, every oil change. I could go through a bottle of the treatment a week. Great for a diesel pickup. Not practical for a semi but I tell ya, it works great.

This stuff works well in my 2005 5.9 Cummins. I don’t see a mileage gain, but engine runs and idles smoother.

Good product noticed big difference on my Mercedes diesel

I found it helps with my mileage and trucks runs smoother !

Works very well, had to order again

Works well
