Review on AR9100 Friction Modifier - 1 Gallon Bottle For Treating Up To 128 Quarts Of Engine Oil by Jacob Fish
where's the benefit?
I've tried this in all my vehicles. F250, VW Jetta, Motorcycles and have yet to see an improvement or difference. Mileage is tracked with each fuel fill-up
Pros
- My truck runs and sounds different while running archoil. Smooths out idle, with more noticeable power.
Cons
- Pure snake oil, no benefits whatsoever
