About 6 months ago I was reading this thing with my dad about people adding 2onces of 100% acetone to like everyother tank of gas. It said it helps the gasses vaporize and burn better or something along those lines! I thought there is no way in hell I'm putting that in my car, but it turns out I talked to my dad today on the phone and the guys he works with have been trying it on there old beaters. One guy has a geo metro, and said in just the first tank of gas his mileage went from 28mpg to 37mpg. and the rest of the guys said they had similar results. I'm not saying you should all do this, i'm not going to but just thought it was interesting and wanted to pass it on.

This is an artical on why it works. If you can really belive it.

Uh... I'm gonna go ahead and call BS on that one.

I have run other types of solvents/paint thinners in my gas. I've used Tolulene and Xylene in much heavier concentrations of 5:1 with gas and I can tell you that those increase your octane but not your mileage.

Okay, I bit on this just for the heck of it. Went to the link and read the article. It all sounded pretty good till I read this line.....

"For instance, a SMOOTH flow of air into a carburetor or injector is far better for mileage than turbulent air. Turbulence is bad."

Ummm.....I don't know too much about injection but I don't think air flows through injectors. I'm now questioning the author of the article.

Looks like more of an ad for scangauge to me, I agree with jmortesen, BS...

Along with finding this further along in their site:

RESPONSE: That is not what is being claimed here. The opening paragraph of this page states that improvements in mileage by the addition of acetone have been modest, in the range of 2 - 10%, and that some of that is likely to be due to cleaning of the engine

Ah, cleaning of the engine....

I don't think you're going to get much cleaning action out of 2 oz of Acetone in 10 gallons of gas either. Just pure BS.

I think they mean a smooth air flow into the carburetor or throttle body.

I know that the smoother it is the better. This is a true statement. The top intake manifolds, and even the air boxes and tubes going to them are specially designed for that reason. but ya i'm with you on the BS i'm not gonna bite! I am courious to here what the guy with the geo metro says in a few more tanks of gas. If his car still runs by then!!!

Another Fairy Tail.

I've studied this for about six months. I drive a 1996 GMC Safari van that I've owned for approx. three years and I've kept a log on fuel consumption from day one. Prior to trying the acetone additive my mileage ranged between 13 and 17 mpg. I recently took a vacation to Washington State (My Mom lives on the Olympic peninsula). I live in Orlando. This would be a good time to put the acetone to the test. I added 3 oz to every 10 gallons and the results speak for themselves. The van ran flawlessly. The fuel mileage increased to 17 to 22 mpg. Every element of driving. Flatland, mountains, city and country. Total mileage for the trip was 7390. It works! Unless you've done a comprehensive test don't be so skeptical. With gas prices at $3.00 a gallon I'll try anything.

i'll give it a try....

I have it on good authority that the same results can be had using 3oz. of wizz in 10 gallons of gasoline. Give it a try, and let us know how it turns out next time you're on a long trip.

So do you drive your van every day for long stretches on open highway almost exclusively? I don't see how you could make a valid comparison otherwise.

I can't be sure, but i reckon it's BS. I also have some issues with that web article: "Acetone allows gasoline to behave more like the ideal automotive fuel which is PROPANE" I don't know why propane is the ideal automotive fuel?

I could be wrong, but if acetone allows more fuel to vaporise, it would be because the vaporisation energy required would be less. This would seem to me to work in the opposite way to something like water injection, which is vaporised - taking more initial energy and preventing knock. Wouldn't acetone then do the opposite and increase the likelihood of knock (reducing octane number of fuel). I am no 'expert' on this and my thinking could be off. Also, acetone has a smaller HHV (higher heating value) ~31MJ/kg compared with gasoline ~47.3MJ/kg, which means that the chemical energy released in combustion would be less too - suggesting less power. I am struggling to see a whole lot of positives coming from this.

I would also imagine running acetone would stink - literally!

Don't take this as gospel - i could be way off here, just trying to think this through logically. However, i would like to point out that in everything i have read or seen on this acetone really seems to have a placebo effect - nothing solid, no double blind scientific tests.
