"In my 6.0L PowerStroke it was truly incredible. My first refill at the same station and the same pump, I hand calculated 19.5mpg, that's around town with some freeway driving, it's usually an average of 16mpg. Also the power and performance level increase with this product in your fuel is a whole new experience. When towing heavy trailer loads of hay last weekend my low end power had increased substantially. The exhaust tone of the truck was also noticeably cleaner sounding and all gauge readings were in the sweet zone."

Bought to clean injectors on 2002 crown vic with 80,000 miles. Also bought 6400-d for my 1996 7.3 with 150,000 miles to clean turbo. Have not had chance to do truck yet
decided to try it out after watching Bill Hewitt from Powerstrokehelp.com’s youtube channel on how he praised how well the product is. I noticed right away that my engine ran smoother and more quiet. Highly recommend this product
Ran this in my truck according to the directions and gained about 1mpg. Love ARCHOIL products—lifetime subscriber. Truck has 65k miles. 2017 F350. Thanks!
This must be a relatively strong concentrate. Unless I'm losing it, I believe I could smell the cleaner in the exhaust on a cold morning. Worked as advertised. No complaints
Even foreign autos need help to make it to 300,000 miles. I used the AR6400-G and AR9100 in a 2010 4Runner with 109,000 miles on it. By the end of the first tank the MPG indicator was up 1.3 mpg. Not amazing butt it showed me even with regular oil/air filter changes gunk still happens. Now after the second tank of gas and mpg is still 18 -18.1 city. I will be adding AR6200 before the next fill up.
