Review on AR9100 Friction Modifier - 1 Gallon Bottle For Treating Up To 128 Quarts Of Engine Oil by Cashout Harden
Good insurance for your engine
This stuff is great for the longevity of any engine. Their fuel additive is even better for any diesel engine. Pure snake oil, no benefits whatsoever.
Pros
- My truck runs and sounds different while running archoil. Smooths out idle, with more noticeable power.
Cons
- Pure snake oil, no benefits whatsoever
