AR9100 Friction Modifier
No Archoil product has ever not performed as described.
After using Archoil, instant starts from the injectors. Cures long cranks and smooth idle. Use it every oil change. Satisfied 6.0 owner.
Helps to quiet down the injectors and provides better lubrication. I once had developed some stiction issues with my 05 Excursion at about 120k miles. But they went away when I started using this.
I have a 05 Ford F350 6.0 with 235,000 miles on it I tow a 5th wheel about 14,000 lbs using the archoil oil treatment the truck runs great it's quieter also I use the fuel treatment together makes the truck preform great and better fuel economy
