Will acetone improve gas mileage?
Pure Acetone can be bought at $7.50 per quart (32 fl oz). So if you used 2oz per 10gal, that would be 16 tanks per bottle. $7.50/16tanks =~ $0.47 per fillup. So you’d be saving $12.86 total every time you filled your gas. If you fill your 10gal tank, once a week, you’d be saving $668.72 a year. I don’t think the savings is completely correct, because I didn’t factor in all the variables, but it is a good starting place to show how much this could affect you. If there was really a 10-15mpg increase, it would save a lot of people a lot of money.
