"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"
Very pleased, and will continue to use
I use this product at every oil change on my 6.0 diesel and I highly recommend it. Great results!
added to every other oil change (rotella 5w-40 oil every 5k) on both my 7.3 powerstrokes, first time using expect the oil to be a bit darker from the archoil cleaning out all the crap deposited in the HPO system.
I have been using the oil and fuel products in my 6.0 for years. They have added much life to the engine especially the injectors. Still going strong after 316,000 miles!
I added AR9100 to NAPA full synthetic oil (Valvoline) at my last oil change. The Ranger has almost 140,000 miles, in top condition, runs great, so I'm keeping it that way. Now it runs noticeably better than EVER. I keep detail records on service and fuel use, so I can compare performance last tank, last month, last year, and weather - driving conditions. I'm getting about 4% improved fuel mileage, and depending on color of the oil, expect to extend this oil change interval from 5,000 miles to 7500. Thanks ArchOil.
