Saw this advertised on Trucks. It's supposed to refine the gasoline to the grade it was when it left the refinery. According to them with the higher quality of fuel comes better fuel economy and better performance.

Anyone seen these used or heard of them?

I to had the same question awile back on another forum-from what ive been told if you have the money to buy it it does give you about 1MPG better and certainly doesnt hurt, but thats about it. Numerous people told me that if it was so great for what it did than automakers would be all over it but there has been no actual proof of it doing any good. I would Use your money for something more usefull

Couple years ago I looked into all these types of things. Did'nt try this particular one though.

I did do the acetone test on 3 different cars. Two were FI and the other a carbureted car. The two FI cars saw very very little gain. IMO not worth the effort. (2003 V8 mountianeer & a 94 GP) On those two cars I saw the most gain in steady state freeway type of mileage. But for around town driving I saw nothing. Since my driving is 50/50 & I was averaging 0.5mpg better.. I decided it really was not worth the effort.
However!! My 87 MCSS (5.0L w/4barrel) most definenately saw an improvement in smoothness & mileage! I was shocked actually. I even had to adjust my idle speed down! On that car I saw an avg of 2.5 to 3.0 mpg better in 50/50 driving. No joke.. it made a significant difference.

The acetone thing is the only one I've personally seen work. But.. IMO it's not really worth the effort on a FI engine. The way fuel is "injected" into the intake port on a modern FO motor, it's already atomised very well. Adding acetone just gains so little.

btw, I've now started to do this for the ranger. I'm carefully keeping a log and will report when I come to a conclusion.
