Ed, that was I, who had posted about field-testing the acetone. Long story less: there were too many variables, involved in normal driving, to draw any concrete conclusions about its net effect, on mileage. Myth Busters, coincidentally, did an examination of acetone's effect, & altho I didn't see the episode, they reportedly tested a new/modern F.I. car, and an old, carbureted 70+-ish Old mobile, performing on a dynomometer. Their test results were supposedly inconclusive, or slightly deleterious (bad) with acetone usage. Interestingly, altho Mythbusters does repeat its episodes, I haven't been able to watch the show. Speaking OF variables, there is the issue of altitude-effect (I live at 4k') , gas quality/grade, type/compression ratio/tune of engine system, and style of driving, AND modifications to the engine, that I made (installed a viscous fan clutch, and something else, I did, too) after I established a mileage baseline, on a long trip, after I started using acetone. I may try installing a few ounces, with a couple tankfuls, enroute to Tulsaville. So, acetone did not, apparently, produce dramatically different (+/-) results during my around-town-mostly driving experience, with it.
