"You can add Diesel Tech magazine to the long list of testimonials as we're now believers in Archoil too.
"Improved fuel economy, smoother running engine and no issues with cold starts."
Stinky but provided a significant improvement in MPG. I will gladly put up with the stink! :-)
Increased my gas mileage by 10%, performed as advertised. I even saw an increase when pulling my 43 foot Grand Design. Good product I will continue to use it
Great additive has increased my mileage over 10%, which is a win for me. I haven’t pulled my 31 ft trailer yet, but I expect better mileage with that load also. Am a customer for as long as I have a diesel.
My truck starts and runs better since i started using archoil 6500!!!!!
If have a diesel you should be running these products. Old or new it’s a must! My 2017 runs better and if it also helps delay fuel pump failure I’m sold!
