I say try it, I have been using Acetone in my vehicle for the past three months, it gave me an initial 4mpg boost @ 1mL per gallon and has remained consistent ever since. My car didn't seem to like it when I went to 2oz per gallon, but each vehicle may react differently to the mixtures. Optimal for me is 1oz per 10 gallon and along with my driving techniques and simple mods I have gone from 27mpg to 45mpg, (Check my Logs)

I also recently did a blind test on my wife car, and we also saw a 4mpg jump in it and then a 7mpg drop with the subsequent tank w/o Acetone.

So best not to take anyones word for it, try it. A 1 or 2 tank test will not harm your engine and of course once you stop all conditions return to normal. But without it I would not be at the MPG levels I am at now with my automatic ...
