"Seeing this F-350 go from a cold-blooded, rough-running basket case to a truck that ran as smooth as it did the day it left the dealership definitely made believers out of us."
"Archoil is the Real Deal"
I have not noticed any changes in engine performance as of running product for 2 weeks , so more testing is required but as of today I have no changes to fuel mileage or performance have been noticed...
Great product. I use in all my vehicles & cycles
I've read all kinds of reviews on different Powerstroke forums and every single person says Archoil 9100 friction modifier saved their injectors on a 6.0 and helped get rod of stiction. If you own a Ford 6.0 then this product is a must at every oil change!
Love it. Makes my Jeep 4.0 run cool, quiet, and smooth. I'm sold and have been using it on every oil change for 2 years now.
