"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"
Changing oil regularly and adding Archoil's Friction Modifier with each oil change is like making love to your motor. My motor likes it and it makes me feel good.
Use this in my v10 in my motorhome every oil change, makes it run smooth great stuff
Use it in my 6.0 for fuel injector health
Fantastic product for any heui injector system. Always buy 1 gal jugs, one came with a little jug an the other one didn't. No big deal, I go through 2 gals a year. Great product!
What’s there to say? It’s a very good product. We had a f550 with a check engine light on and it was because of random misfire with the injectors. We changed the engine oil and added 16oz of friction modifier and the light went off and has stayed off. I recommend this and all archoil products to all my friends. I would give it more stars if I could.
