The idiots on our local news did a story featuring some old guy who tried adding the acetone to his tank and he claimed he got better mileage (I think it was up about 10%). I would dispute it and also noted that when they showed him adding the acetone he was using a plastic measuring cup that was disolving as he was pouring the stuff into his tank! Wait until some of that plastic residue starts clogging up his injectors or fouls his fuel pump up...then we'll see some lost economy!

I conclude that we all perform flawed tests when we try to prove things like the acetone theory. Subconciously this old guy wanted to believe he could save some gas by adding a couple of ounces of miracle acetone to his tank - so what does he do? Subconciously he drives a little lighter on the gas pedal, maybe coasts a little more to the stop sign and red lights, perhaps instead of 65 he does 60 on the highway...that would easily cut 10% off most people's fuel consumption. So my theory is that acetone is not a miracle additive...if it was wouldn't some genious be selling it in 3 ounce bottles at pep boys? Or better yet, wouldn't the oil companies just love to sell super premium fuel that gets 30% better mileage for just 20% more money??? Sure they would if it worked...I would bet anything that if a blind test were performed using a sizeable sample that no measurable gain in fuel economy would result from the adding of acetone to fuel...just my $0.02.
