"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 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.
than 500 miles to stop smoking during startup. At about 1500 miles the smoking was greatly reduced. My '01 7.3L, 125k miles, was smoking really bad due to my lack of maintenance. Too many curves in life caused me to be lax on oil changes after four yrs of owning the truck whereas it never smoked before this time when doing regular oil changes. So I bought two bottles and after about 1000 miles I called asking if I should add the second bottle since it was still smoking at startup but not as bad as when I added the first bottle to an oil change that had happened about 500 miles earlier before adding the bottle. The customer rep said I should just wait until the next oil change and shouldn't double dose. I gave my email to him so he could send me one of their instruction tip sheets which he had offered to do. I said thank you for the info and hung up. Email shows up, plus he offered to send me a free bottle. I never asked for it, He just offered it to me! Great Customer Service! Also to repeat. that now at 2k miles the truck is smoke free. So the product works, just took longer in my case, but also I don't put a lot of miles on it each week either, less than a 15 mile commute each way.
