Ok, so acetone in a 2000 Dodge Neon in my experiment did not turn out good.
I went from a pretty constant 31 down to 28.3 (look the attached picture of my fuel logs) You can try to say it was because of my driving making the difference but obviously I have pretty consistent numbers for the last 3 or 4 weeks.
