Replying to: gagrice (Aug 09, 2008 8:30 am) everyone has their own opinions and everyone is entitled to them. ( not saying you are wrong so please dont take what i said as an attack at you or anyone) i personally like to test things on my own to determine if whats being said is true or not. there is always a "yin" and "yang" to everything and the only way to determine is to test test test. that is my opinion on the matter even doing just one test on a subject is never enough to get feed back. i mean when we all started learning how to walk, did we try once and fall and decide that walking doesnt work but meanwhile people all around us are walking everyday? of course not, we get right back up and try it again and again and again until we get it right, just most people and i mean 99.9% of people give up just shy of success and then determine that something doesnt work and have that opinion and spread that to the world of people they know and so on on the other hand you have someone who keeps on keepin on and finds a whay it works and tells everyone they know and so on and so on and thats why we have the "yin" and "yang" again, just my opinion

...the only difference is the purity level, and you can find 95% pure (or more) just as easily at AutoZone as you can at a beauty supply shop (it's just waaay cheaper at AutoZone). That said, I have a few comments about the Acetone scam: 1) Acetone has been scientifically tested as a gasoline additive since at least the 1930s, and never once has it ever done anything but reduce fuel economy in any published study. 2) Mythbusters, Snopes, et-al. have tested this stuff repeatedly, and so far at least, the best and most optimistic test shows a zero increase in fuel economy (all of the rest showed a decrease). 3) Tests by individuals are statistically irrelevant and usually fraught with errors. The fact is that it is very difficult to control your driving and the environment to any acceptable degree, and there is absolutely no way you can "test" acetone and then say, "See, it works." 4) With point #3 in mind, there were a bunch of Acetone advocates populating this board back in 2005, and they were claiming "at least 35% fuel economy gains" from using ~3oz per 10 gallons of gasoline. I didn't believe a word of it, however, to quiet their protests of, "How are you going to know if you don't try it?", I tried it. At the time I had a very consistent 55 mile commute (each way) that was Cruise Control for all but 3 miles, and my fuel economy in the old car that I was driving was a pretty consistent 22.5 mpg. I ran ten consecutive tanks with the acetone additive, and not even one of the tanks made it as high as 22.0 mpg (two tanks made it to 21.2, and the low tank was 19.7). So much for "at least a 35% gain". Long story short, it is quite certain that folks who get better mileage do so because they are conscious of how they're driving and keep a smoother throttle. Had they done the same thing with regular pump gas, they would most likely have gotten as good as or better mileage. The good news was that after I posted my results, the Acetone advocates left us alone here and went somewhere to make their pie in the sky claims. Best Regards, Shipo |

Replying to: richiev (Aug 09, 2008 9:28 am) I haven't read up this, but I would think you're looking for 100% pure acetone from Home Depot, Lowe's, a hardware or paint supply store. I'm dubious, but I AM curious how it goes. |
