Question Acetone in Gasoline...good idea???

I have heard that it was a good idea to mix 3 ounces of acetone to 10 gallons of gas...for better performance and gas millage...because of the high octane...has anyone heard of this before???

I've heard it.

Some say it works, some say it doesn't... some even get LESS gas mileage.

The only thing I put in my tank besides gas is fuel system cleaner every year or so.

On Mythbusters they showed it didn't hurt/stall the engine.
They didn't dyno or test anything.

Your car will burn cleaner when you add rubbing alcohol into the gas. (Like one 8oz bottle per tank.) Some people have passed sniffer emissions test with no cats by doing this. Some have also failed because the car burns too clean.

Another thing that you may or may not care about. Eventually alcohol will eat your fuel lines. But it will take a REALLY long time assuming the concentration stays low and you drive fairly often.

Just a rumor/myth.

If you want to, try it for yourself and see what happens lol.

How can you fail an emissoins test if your car burns too clean?

The car model rated for a given range on the results, if you are out side that range you fail. High or low it doesn't matter.

The short answer

I have added about 3 shots for 10gals to my wrx and it has not hurt it, but i cant say my gas mileage has improved either. But with an 18g it spools fast and eats gas so its hard to tell.

On performance it may help but the timing on the car is conservative so without any more timing or being closer to the limit it does not seem to gain anymore. But idle seemed to be smoother.

My buddy in a z28 camaro said it seem to help him so it may help but not that significantly.

if you have a dyno it would be interesting to see what results you get. but i think the gains are so small that it will probably be overlooked.

if you want performance you probably want to go with meth

wow, im not sure what you said but it sounds like you know what your talking about. i have to find out if the emissions will work on a gas powered car, I know they work for trucks that run on diesel but if it will tell me the difference between acetone gas and regular it would be greatly appreciated. I plan on running catless for the rest of my sti's career and im trying to pass emissions in 1 year

I did a lot of research into the area of adding acetone into gasoline. The theory has existed since around the mid 1940's, so it is definitely not a new idea, just one that won't die.

Fact: Injector cleaners you put into your gas are 99% acetone and 1% of some of their dyes w/e.

Fact: Adding acetone into your gas is basically just raising your octane level

Results have been all over the place. I added 4.5oz of acetone per complete tank, the car ran smoother and I received any where from 2-4 mpg better per tank. This was consistently over the course of several tanks before getting lazy and not doing it anymore, which then showed 2-4 mpg decrease. I calculate my mileage at every fill up. Theres a real good wiki on it out there, that people post their own results. YMMV just remember that.

Other uses is adding a table spoon of acetone to a push mower and it will run smoother, longer, and get rid of that black smoke it blows out some times.

***IF YOU ARE GOING TO ATTEMPT IT, USE A FUNNEL OR REUSE AN OLD INJECTOR CLEANER BOTTLE, ACETONE WILL REMOVE PAINT IF IT TOUCHES***

okay thanks, so your saying instead of running injector cleaner a little bit of acetone will do the same thing? also im gonna calculate my highway mileage now that i updated my v2 AP and it has a fuel economy mode i will find out how it does on like 50miles of pure gas then 50mile w/ acetone mix. or something along them lines. i will calculate it and get some numbers up for you guys.

that's nice to know. I guess acetone is a little cheaper than injector cleaner. Do you happen to know how much acetone do you have to add per gallon? cheers, congratulations on the research

it's 3 oz per 10 gallons, however i was really empty when i filled up with about 14 gallons. Again its all about testing. Some people have found better results with 2oz/10gallons, but don't go much over 3oz/10gallons.

also to note, that you have to compensate the ratio, because you may only be putting 5 gallons in at a fill up but your still putting x amount of acetone into a 15.9 gallon tank. have fun.

It was one of the less recent examples of how a twisted myth is more pervasive than the source of its existence. I could tell you straight to your face the entire story behind the entire acetone rumor, and no one believes me outside of people that have used Oxytane and finally understand it.

So, we just kinda left it at that and went about our business. What's funny is how many people still try to debate specifically acetone in gas and not the source of the rumor. Even if you tell them, they still don't believe it. The absolute 180-degree, about-face of people's opinions who finally understand it gets me every time. I went through the same thing when I finally saw it with my own eyes. Getting to work with that stuff in blended ethanol fuel showed me things I never thought possible with fuels.

The answer isn't acetone. The answer lies at the root of the rumor.
are we searching for the holy grail in the last crusade or something? what a cryptic answer. i feel like if i find the answer, i'll live for a thousand years.

The truth to the rumor isn't acetone. There's controversy over the results because people can't seem to duplicate the mystery they heard about.
