Does acetone really help your fuel mileage?

[revpilot]

Had a guy from Mississippi balancing my airplane prop last week. He tells me he went from 8 to 11 mpg in his motorhome by adding an ounce of pure acetone to 10 gallons of fuel. This guy was kind of a mathematical genious who makes a couple thousand bucks a day, so It got my attention. Does anyone know first hand if it works? Will it kill something else? Is it hocus-pocus?

dont count on it. Ive tried fuel treatments which made similar claims and actually smelled a lot like acetone and it did nothing.

I use acetone daily with fiberglass. I wouldn't use that stuff with mechanical parts. It is very corrosive. I don't see how an ounce of acetone added to 10 gallons fuel could make that kind of difference in fuel economy. But I am open to being corrected.

Wonder if it cleaned up the injectors? Only way I could see that happening!

Bad news on rubber parts. Don't run it in your gas. Folks who say it helps mileage are continuing an urban myth.

straight acetone will improve fuel milage in a diesel but it also eats anything rubber and erodes metal objects in the fuel system ,any how if it is something you want to run for a while dont use it, short term gain isnt worth the long term pain

Acetone=mileage not!!!

I tried this on 2 different vehicles about 3 years ago.

It does NOT do anything for mileage.

I really watch my mileage on my vehicles on every fill up. 1 rig was a mileage rig--1 was a BBchevy. Made no difference with or without.

My opinion--do not waste your time.

The theory behind it is that it creates smaller gas droplets so you get better burn. However, there have been some tests over the internet. The ones that seems legit do NOT backup the increase in mpg.

Didn't they bust this on Mythbusters?

Well, I guess the nays have it. I'm glad I don't make my living selling fuel additives to bilers
