You've heard it, I've heard it. People claiming that adding Acetone to their fuel's mixture is giving them better gas mileage. I've personally tried it a few times and without precise instrumentation, the difference was virtually unnoticeable.
Finally, one day I decided to get off my behind and give it a try using the
ScanGauge in my '97 Geo Metro. No one had ever tried to do this experiment before because it was inconceivable that one could do appropriate A-B-A testing on it. To get around this, I did A-A-B-B testing followed with a C just to throw in a curve ball.
Check out the results on this video (please ignore the obvious spelling error at the beginning
