"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."

Best thing i’ve tried for my inboard boat.
I purchased this and the oil treatment. Together I have noticed my truck runs smoother and have noticed an increase in mpg and horsepower. I liked them so much I already ordered them both for my next oil change.
Have noticed a significant difference in the performance of my 6.0 since I began using Archoil products. Great Product and I will continue using for the life of my motor.
Product seems to have rehabilitated the original Garrett VNT-15 turbo in 2002 VW TDI. Will keep using AR6400 as directed.
Archoil products keep my truck running smooth even after 200,00 miles. Will keep on using.
