Saw a video in the DIY thread about adding a couple ounces of pure acetone per 10 gallons of fuel to improve MPG.
Any feedback on this?
Is this a good or bad idea?

Some automotive enthusiasts add acetone at around 1 part in 500 to their fuel, following claims of improvement in fuel economy and engine life.[9] Systematic testing has determined that acetone has no measurable effect on fuel economy or may in fact reduce engine life by adversely affecting fuel system parts.[10][11]

The effect of acetone on fuel economy was addressed on the popular American TV show MythBusters in 2006, in which they observed a decrease on fuel economy.[12]
