it'll destroy your engine...plain and simple


that's a trick that drag racers use...the only reason they do it is because most of those guys tear their engine down after every event, if not every race...

it will break down the lubrication ability inside the compression chamber as well as increase your compression exponentially and can cause the motor to literally fly apart...

Doubling your mileage it won't. It can increase it some -- but at the cost of many things over time.

Many injector cleaners have acetone in them to help clean the injectors. But they even tell you not to add over a certain amount per so many gallons to prevent problems.

The myth of great gains goes back to carbeurated days when it was necessary to cause the fuel to evaporate to get it atomized in the air stream. Acetone does help that.

However, you're running an injected engine that creates it's own atomizing stream without relying on the ability of the fuel to be vaporized by a moving air stream. It does very little for an injected vehicle really.

My opinion: cons outweigh the pros of using it.

its a myth plain and simple... the best way to increase your mileage is to use RUG and drive conservatively

I have been using acetone in my Ranger on and off for around two years now and I can tell you it will not double the gas mileage. However, I do get an increase of 1/2 to 1 mpg (city mileage) when I use it. The strange thing is when I stop using it, the gas mileage does not drop right away. I have come to the conclusion that acetone cleans the fuel system and that is the major reason for improvement in mpg.

I disagree with the potential for damaging the fuel system and engine. The amount added is not enough to cause damage. I usually add about 2.5 oz/10 gallons. That is about 0.2% and is not concentrated enough to attack plastics or rubber. I am a Chemist and work with these kinds of solvents everyday. I do have a good understanding how they work.

Have you tried using a higher concentration ?

Nope. 2 to 4 oz/10 gal is what is recommended. I get decent results with 2.5 oz/10 gal and doubt it would improve from there.

That's a pretty reasonable dilution. I agree that probably wouldn't make much difference. That probably equates to what is in most injector cleaners I bet. Your answer makes sense to me.
