acetone improve fuel economy?

This urban legend is making about its 12th trip around the internet. The idea that such tiny quantities of any aromatic would have any measurable effect on anything other than the ego of the purchaser is ridiculous. Somehow these "secret tricks" always escape the legions of PhD petrochemical engineers who do this kind of thing for a living.

tried inj. cleaner all brands acetone seem to work better on old cloged inj.

has anyone ever tried to use acetone in the fuel tanks and has anyone had any sucess?

Acetone's main benefit is an increase in the knock rating of fuels like regular gas. With carb'd engines it does contribute to improved vaporisation if there are challenges there, though at high cost.

If tuning an engine for more timing can gain mpg, then it may decrease gas usage via the anit knock quality, but the cost of adding the acetone is generally higher than the mpg benefit gained.

With a stoic not that much different from E85, for improved anti knock easier to add E85 if you can get it. It's less than one tenth of the incremental cost.

I use toluene as an injector cleaner. It's available cheaply in gallon jugs at any paint supply store. It's also an OK octane booster if unleaded race gas isn't available. Add some Uplon lubricant if using any meaningful concentration in your fuel.

Organic Compound ______________ Boiling Point, °C.
Acetone _____________________________56.5
Methanol ____________________________ 64.7
Ethyl acetate ________________________ 77.1
Ethyl alcohol (100%) __________________ 78.4
Ethyl alcohol (95%), the azeotrope ______ 78.1
Propyl alcohol ________________________ 97.2
Water ______________________________ 100.0
Butyl alcohol ________________________ 117.5
Amyl alcohol ________________________ 137.8

if you were to make Ethanol to run your car you would need to distill out other compounds that are not favorable. I grew up with 55 gal drums of Acetone around me. The stuff is a great cleaner and other the distorting/attaching plastics and rubber products it cleans metal. Squeaky clean metal will oxidize. Fuel lines will rust from the inside out. The rust gets in the injectors and damages them. I have seen pictures of injector components under a microscope after running ethanol in a system that wasn't designed for it.

CalEditer,
Are you saying that acetone causes your fuel system to rust out?

Correct
Some fuels will corrode non stainless steel fuel lines

So acetone will rust fuel lines from the inside...

Aren't most modern fuel lines made from aluminum plastics or stainless materials?

are you saying that using E85 in my 2000 S10 that isnt designed for it will hurt it?
ive always wondered. never tried because i didnt want to find out the hard way.

Thanks,
