Fixes Loss of Power
I was having occasional "Loss of Power" issues in my pickup truck, especially when towing in elevated areas. It acted like the fuel filter was getting clogged. After a little web-search, I tried Archoil Diesel Fuel System cleaner and it made a big difference. Overall mileage per gallon went up and I experienced no loss of power issues. I add it to my fuel tank every 5000 miles and the engine runs great. I have made multiple purchases and plan to continue using it.

Got my turbo vanes moving again
I’ve got a 2020 Kenworth T680 with a Cummins X15. I ran a turbo hysteresis test and my actuator wasn’t working. I’m on the road so I couldn’t pull it off to check if it’s bad or the turbo vanes were just all sooted up and stuck. I went ahead and threw a couple bottles into my tank and a few thousand miles later threw in 2 more. Well the actuator passed the next hysteresis test. I didn’t do anything else so I’m saying it cleaned up my turbo enough to get old VGT VTGing again 🤘

As Described
Great additive, I have noticed an improvement in my turbo performance and acceleration. I have been adding it every 5,000 miles as directed, going on my 4th bottle. My friends use this too after I recommended it and they have also notice a big difference. We also use the archoil AR6500 fuel treatment and we have all gained 1 1/2 to 2 miles more per gallon. Great product

Great product
It seems to have really helped my tractor. Before using Archoil, my tractor engine surged and would not maintain a constant RPM. It is now running very smoothly. Thanks,

It works.
I have a 2003 series 60 egr engine in an RV. I was getting a check engine light code for egr valve not responding. I suspected it was carboned up so I decided to try this product. After 1 tank, the check engine code is gone and I can feel an increase in power. There is a hill where my bus would always downshift. It doesn't downshift now, maintains set speed and powers thru! I don't know if I've seen any improvement in mileage, but I'm happy with the results thus far. I have now ordered the fuel conditioner as well. Good product!
