"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"
Good product does what it says it does
My 99 f350 7.3 wouldn't even start if it sat for more than a couple days, if I started it every day it would surge bad for 20 seconds, after putting this in I drove it for 20 miles and the next day it started right up cold and ran perfect like was ever wrong, I am truly amazed
This product solved the problem I had with my F350 not starting easily when temp was close to freezing. I’ll be purchasing more.
I run this in all my diesels even my 6.7 300 plus miles on my 6.7 no issues
AR91000 works great in my old 2001 F350, 7.3 , it made it run so quiet, my neighbors ask if it was running. Plus been using it in a 2006 Malibu 3.5 and it has 260,000 miles on it, also run it in my Gravely Zero turn, I highly recommend use of this product in any motor.
