I tested Acetone with a scanguage as well and it did make the scangauge read much higher on the 98 buick, but when I did the ACTUAL fill ups the increase was quite small and only seemed (in my case) to work in the winter months. I believe (if memory serves) that acetone tends to foul O2 sensors, I do not think this is something that will consistantly improve fuel economy, but it does make the scanguage think you are getting good fuel economy (just not in reality)
I also found that acetone in Seafoam really cleans out the intake, about the only cost effective use for acetone.
