Acetone improves your fuel mileage. How does it affect engine parts?
Ive been doing some reading on using acetone as a fuel additive. Alot of average users have indeed said that adding acetone (the right amount) to gasoline in their tanks have improved their mileage. From my understanding, acetone weakens the surface tension in drops of gasoline, hence making it easier to vaporize. In addition to improved mileage, some users have even reported that they notice an increase of power in their cars (mazda protege forums). Here is a good page that describes this:
A simple Google search will yield many more results. The mileage increase is obvious, but I am wondering how the addition of acetone will affect engine parts like rubber seals. I am mostly worried by the fact that acetone corrodes plastic parts. But isnt ethanol (its already present in our gasoline isnt it) more corrosive than acetone? Keep in mind that the acetone normally added to improve mileage is about 0.2% (reference: wikipedia).
So before I try adding acetone to my car, I'd like your guy's opinions. A Google search can only yield so many results. I was wondering if someone with a scientific/engineering background could perhaps shed some more light on this issue. Thanks.
