Apparently adding a small amount of acetone to gasoline will increase gas milage, performance, and idle quality.

I'll probably try this out starting with my next tank and post my findings here.

FYI: I'm driving a '95 Saturn SL1 getting around 30MPG at about 99.7k. ...yes, I have a 10 year old car with less than 100k miles. Long story.
