"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've been using the AR9100 additive in my 6.0 Powerstroke for the last 100k miles at every 5000 mile oil change with T6 Rotella. It has drastically cut down on warm up times before driving and I have zero hard start/below running temp engine injector issues. It has eliminated having to let the truck idle 10-15 mins before driving after the first start of the day, regardless of the temp.
It's been 10,000 miles from oil chg. gear box and drivetrain service. My 93 Dodge w250 runs notices ably quieter, and smoother. I'm very satisfied with the results. Thx
I was having horrible stiction problems with my 7.3 started hard had horrible injector clatter and truck shook really bad when cold I added archoil when I changed the oil started it up drove it around the block let it sit till the next morning and has fired right up and ran smoothly ever since with no injector noise
No problems great product!
Really helps overcoming the Ford 6.0 design problems. Good insurance against engine failure.
