Better mileage by adding acetone to your fuel?

[NIKAL]

I was talking to a friend and he was telling me about adding some acetone to his fuel and he has seen about 1-2 miles per gallon increase. He has a Toyota Land Cruiser and has been doing this for awhile now. As interested as I was, I was also skeptical. So I started to look it up on the internet, and suprisingly there is quite a bit of info on it. I then called one of my friends who is a mechanic and he said he has heard of this before, but had never tried it. He was saying that if you look in many fuel additives you will see Acetone is an active ingredient. His only concern was that he did not know what it might do to your catilitic converter over time. He was also telling me that years ago people would pour some rubbing alcohol in their tank to help pass smog. I guess it helps with hydro carbons?

Has anyone else heard of doing this or has anyone ever tried it? Here is the link to the report about adding it and getting increased mileage.

I've heard of it too.. for a long time now.. (the rubbing alcohol too) but for as long as I've been hearing about it, I've never heard any clear cut info about what happens to the cat, which leads me to believe all that tried it have had to pay to replace cats, and their too embarassed to admit they messed up. LOL

I also have heard of this, but if you decide to do this, first figure out if the 1-2 mpg difference is worth it. possibly try to coast a little more and drive like you have an egg on the gas pedal, you will get the same 1-2 mpg and save the money.

I read into a while ago and gave it a try. Did notice a little improvement. I read not to use to much as more is not better obviously. The article said it will raise the octane thus making the fuel harder to burn equaling a decrease in MPG if too much is used. The ratio I think was something like 2%. I know it was about 2-3 ounces for a 15 gallon fill up.

They did this on Mythbusters...which came up as BUSTED....does not help your mileage.

You beat me to this.....

MYTH BUSTED.

Acetone does worse for your MPG

Great Gas Conspiracy

Myth: Automakers and fuel suppliers are in collusion to keep us dependent on expensive gasoline and inefficient cars. There are many devices that one can use to cut your fuel consumption.

They got a carbureted car and a fuel-injected car to test several types of devices. The cars were placed on a dynamometer, which allows the car to drive without moving anywhere.

Test devices and additives:

* Fuel line magnets: working on the "principles of hydrodynamics," they are supposed to align the molecules for more efficient consumption.
* Acetone additive: supposed to make gasoline burn more efficiently
* 300mpg 'super' carburetor
* Hydrogen fuel cell generator: flammable hydrogen gas produced by electrolysis. Adam labeled it "Gasbuster: Stickin' it to the Man"

They tested each car on the dynamometer at 35mph and 55mph with each 'device.'

Carburetor car:

* Baseline: 17mpg at 35mph and 25mpg at 55mph
* Magnets: exactly the same as baseline busted
* Acetone: 16.7mpg at 35mph and 24mpg at 55mph busted
* Super carb: much worse than baseline, 12mpg at 35mph and 17.7mpg at 55mph busted

Fuel-injected car

* Baseline: 19mpg at 35mph and 27mpg at 55mph
* Magnets: 18mpg at 35mph and 26mpg at 55mph busted
* Acetone: 18mpg at 35mph and 26mpg at 55mph busted

Hydrogen fuel cell generator

Hydrogen fuel cell generator: the car started, but it turned out it was due to leftover fuel. They tried again with the residual fuel gone and the car wouldn't even start.

Adam: "My God! It doesn't work! I can't believe it doesn't work. I found it on the Internet, man!"

Jamie rolled a tank of hydrogen gas over and squirted the gas directly into the carburetor. The car started up with the gas, much to the excitement of Jamie and Adam. It was so much fun they tried it again, only to get caught off guard as the gas exploded inside of the carb, ending that particular test.
Cooking oil

Adam picked up some used cooking oil from a restaurant and filtered it to turn it into fuel. They got a diesel Mercedes and drove it around a 2.9 mile course at Alameda designed for constant 35mph driving. With the diesel baseline test they were able to go 8.8 miles on 1 liter (33.3mpg). They then switched to the used cooking oil and ended up getting 30mpg, only 10% less efficient.

They made no modifications to the diesel car and all they did to the cooking oil was filter it.

Mythbusted:none of the devices they tested made the car more fuel efficient. The EPA has tested 104 of these devices, and only 7 showed improvement in fuel efficiency. However, none of these improved efficiency over 6%.

Acetone

Claim: Reduces surface tension of fuel droplets, enabling it to burn more completely. As an added benefit, it is supposed to clean carbon buildup from the engine.
In use: Add about 1 ounce of acetone per 10 gallons of gas.
Observed gains: On the first couple of tanks, we saw some decent gains. After two or three tanks of gas, though, we were back to roughly the same mileage we saw before for no statistically significant gain.

I rather believe the mythbusters. They do have better controlled experiments than what the show only shows

Heck the way it been going here in Charlotte everyone and thier brother is getting their converters sawzall'd off in the middle of the night so I guess long term efects wouldnt matter....

They came up with the same results. Acetone doesn't work. If a scientific test proves it false, a rough test should as well.

Most of the gas saver myths came from the first gas crisis in '74. Alcohol and acitone are oxidizers, and the little check valve you add to the pcv circuit all are supposed to lean the mixture and improve mileage. They may actually work on a carburated car with a stuck float or a stuck choke. But since the mid to late 90's all cars run in a closed loop between the comupter and the O2 sensor. So even if you run oxygenated fuel or add air to the pcv circuit, the comupter will sense it and adjust the mixture to stay right where it wants it to be. So there is no way any device will work on a computer controlled car, and they will have little or no effect on a healthy carburated car.
