You guys can hit 85? :D

I know that it's a touchy subject, and I can't scientifically test anything, but in my old Honda I've seen a significant increase. I tried removing it a few times, and each time my FE dropped. It seems to make more of a difference in older cars with dirty as **** engines.

I may have to try this stuff. I definitly have an older car with bazillion miles on it.....how much have you been adding?

I hope you don't think it's verging on taboo to talk about acetone! I'm all for people trying stuff, even moreso if they try to properly control their tests.

I just wish more people who do try stuff are aware of the folly of drawing conclusions and making authoritative claims without proper methodology.

Obviously you are aware of this: "I can't scientifically test anything". Offering up that disclaimer earns my respect.

Well, I"ll say I can't prove anything scientifically either, thats why I don't rant and rave about acetone. I have noted a 2 mpg increase after adding acetone many times while running my 20 mile east/west test route. That however is not scientific proof. Just my own conclusions.

I feel most of the stuff on gas savers could be construed as non- scientific but some things are still accepted as if they were.
