"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 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.
I've been using archoil for about a year now. Very pleased with the product. I've got an 04 f250 with a 6.0 at 220,000 miles. Runs like it's brand new. This product definitely helps with oil breakdown.
My 1999 Ford E 350 Cube Van Was getting hard to start some cold mornings. After it fired up, it chugged & shuddered until it warmed up and they it smoothed out and ran fine. I generally plug the engine oil heater most nights of the year as it makes it easier & quieter to start as I go to work at 3:00 AM.
I changed my oil a week ago, added the AR9100 & Rotella 15-W40.
I put 1200 miles on the truck this week and have noticed various improvements. It is surprising how quiet it runs. The injector are hardly heard anymore unless the truck is under a heavy load. There is very little engine noise of any kind. It seems to have more bottom end power.
I have four 7.3 's I will be treating them all with AR9100. I am totally impressed and satisfied with the the product and would recommend it to anyone with a diesel engine
Gave my 6.0 new life awesome product
