Review on Restore Your Diesel Engine Performance With Archoil AR6400-D Fuel System Cleaner by Ryan Bowers

Revainrating 5 out of 5

Outstanding product - went from 13.3 MPG to 18.7 MPG, at least for now

I ran the tank near dry, then dumped in the AR6400-D and a tankful of fresh fuel.By the time I had 50 miles on the tank, my average MPG had skyrocketed from 13.3 MPG averageto 18.7 . Normal speeds, driving conditions etc. Truck is a 2017 F350 XLT, obviously with a 6.7Ldiesel. Outstanding product.I have been told that the additive itself is responsible for a good part of the mileage increase, so it won't stay that high on the next tank. Be that as it may, the truck is running like a top and I'll be using the AR6400-D every few thousand miles from here on out.

Pros
  • This Additive does exactly as it claims ....long time user!!
Cons
  • The product may cause engine damage if used improperly
