Stumbled on quite a bit of google research supporting it as a way to increase mpg safely. Anyone tried this?

 

Don't do it. Acetone eats away at the fuel lines and seals.

 

Myth busters found it busted, don't do man!!! Only bad stuff could happen IMO.

 

I used acetone in my 03 camry 2.4. I also had been looking up the benefits/costs of acetone in fuel. It takes a very little amount, a very quick turn and pour really small amount of PURE acetone, not that fingernail polish crap. Not mineral oil either but 100% pure acetone.


I put a very quick pour about 1/4th of a shot glass if not a little less into a half tank of reg gas. When you have enough gas that small amount of acetone won't eat the lines, its mixed in well enough not to hurt anything.


my camry was 165k and getting right at 30 mpgs with steady 70 mph and oil topped off. After I ran just one cycle of acetone on about 3/4s of a tank my mpg was 34. highest I ever got it.


Use at your own risk by all means, I'm just telling you what actually did happen when I tried it that one time.
