"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."

Seems to have worked
Good product, annual treatment, I add the bottle @ empty and then fill the tank halfway. Try to drive as low as possible before refueling.
Trying to clean the EGR to get rid of P0401. So far the light is still coming back on. I turned off with my scanner. Got two bottles still have to run the second one through there. I think I’m going to delete. Only has 46000 miles.
I added the product when my 2008 Ford F-350 6.4 liter diesel truck was down to less than one-quarter of a tank. I then filled the fuel tank. I believe that the product is working to clean because the truck gave an exhaust smell I haven’t smelled before, like it was burning something off. I think the Archoil cleaned the fuel system and what I smelled was the built-up deposits being burned off. It last a day and then the truck immediately did a regen. That tells me my suspicion is probably correct. Truck runs well and so far, so good. I think the product is doing what they advertised it would do!
First time using it. It worked. I usually use the archoil fuel additive, but noticed a little roughness off of idle, like an injector might be sticking. Put this in and it went away. Sold me on it.
