acetone in fuel for better fuel economy

[swapwap]

Has anybody tried this for fuel economy improvement?

Try doing a search. It has been talked about here before. I tried it with no effects good or bad.

If you've switched any of your o-rings to Viton, acetone is NOT a good idea......

have an old buick lesabre,,,,,tried it the other day,,,,still have gas in it where as before i would have been empty,,,jus tryin it out,,,will see what happens,,,put some in my 92 f250 but really havent driven it anywhere since,,,,but will

I watched a thing on Mythbusters about it and as I recall they could not prove that it helped with fuel ecconomy any on a gas powered car. Probably could do a search there and get all the facts

Certainly looks interesting. There is alot of interesting reading on that site... Good geek site. [img]/ubbthreads/images/graemlins/biggrin.gif[/img]

I saw that episode...

IIRC, the acetone in the tank dropped their mpg by something like .5 or something like that...

Yes, I tried it for quiet a few tanks. I also tried it at different concentrations to test out all the theories I could think of. MY answer is, don't waste your time and effort. If I improved my mileage it was only by 0.5 mpg, and that's an IF. I gave up on it before I tore my truck up.

p.s. I bring up an older thread to discourage repeating my experiment.

As a recently retired refinery operator, 2 different companies, a lot of years, I fully believe that if any particular additive would help all Diesel (or gas) rigs, the companies would use it. They actually are searching for ways to save energy. It would not cost them anything to save you a little mileage, they sell everything they can refine, and they can, obviously, charge us anything they want for it.
Before they would use an additive, it would have to be safe for ALL vehicles that may use it. (on or off road use.) It would have to keep their price competitive with the other companies.

I tried this in my '91 F150 with the 300 Six over a couple of months and kept good records. It made statistically no difference.

I put a gallon of acetone into the tank just before each fillup and get about 5% more miles per gallon of gasoline.

OK, just kidding.



Don't believe everything you read on the Internet. For example, from the site cited above,
"Pure acetone is an extremely clean burning fuel that burns in air with a pretty blue, smokeless flame."

So is gasoline, under the right conditions. Here's what most people think of gasoline combustion - orange, uneven, incomplete, sooty:





Here's another example of gasoline burning, this time with better metering and mixing:



I daresay that gasoline, as depicted here, "is an extremely clean burning fuel that burns in air with a pretty blue, smokeless flame."


My point? It's not what you've got, it's what you do with it.


Modern gas engines -- anything with a brain box -- burn fuel almost perfectly completely. If you sample the exhaust gas between the engine and the front catalyst, (and D'oh! - we do that) you'll see no more than 0.1% unburned hydrocarbons. (the instruments we use can't even measure beyond 1%)

If not, we'd have to install a bigger catalytic converter, and that might cost extra. Engine calibrations don't cost anything to manufacture.

So any time someone's offering to boost your mileage by remediating incomplete combustion, run.
