A semi-professional test in a controlled enviroment (dyno) on the same engine and temp conditions, etc, etc, etc has proven there is no meaasureable gain.
I can't find all the links, but here is one, a Q&A from some local experts in my newspaper
Last week my neighbor gave me an 11-page treatise on the benefits of putting a small amount of acetone in your gas tank: an increase of 25 to 35 percent in gas mileage with no damage to the engine. The article tells how much acetone per number of gallons and gives the rationale for why it works. What do you think? -- Wil
RAY: We spoke to a fuel-systems engineer who works for one of the major oil companies. He said that because of all these rumors floating around on the Web, his company tested acetone in its own labs and found no increase in mileage. None. And he said the equipment is precise enough to detect anything over a 1 percent difference.
TOM: But it's worse than useless -- it's harmful. Acetone is the primary ingredient in nail-polish remover. And while it will burn and is a high-octane material, it's also a very powerful solvent. So while it's in your fuel system, it'll be eagerly dissolving all of your rubber components . . . like gaskets and O-rings.
RAY: In fact, some cars have a rubber hose in the fuel line that goes between the fuel-cap assembly and the tank. When you add your acetone you'll be eating through it in no time.
TOM: Here's our final reason: It dissolves paint. So if you slip and spill a little bit outside your fuel filler door, you'll have a nice unpainted line running down to the bottom edge of your rear quarter panel. When we see you drive by, we'll know you didn't take our advice!
I use it as a fuel system cleaner, but it can also be used as a octane booster as
pure aceton has a octane rateing of 150. I have tried putting 100% acetone on a
5hp Biggs&statton engine. Lets just say that 150oct on a engine made for 87oct is
ill advised, it exploded as soon as the acetone reached the engine (i started it on regular pump gas)

So what does any of that have to do with gas mileage going up when mixing acetone into your gas tank?
Nothing
You do realize that 150 octane is LESS volitile than 87 octane? I doubt the motor "blew up" but I would say the opposite actually, it probably wasn't able to ignite the acetone\air mixture and just locked.
Retail packaged 'off the shelf' octane booster additives in general do nothing (the ones in your local auto parts store that come in 12-14 oz bottles). Even the best on the market when added to a camry (that has a 18 + gal fuel tank) won't make a noticeable change in actual octane. If you put in 87, add your favorite brand octance booster to a full tank, you will be at about 87.5 octane Tons of documentation on the net to support that, google around a bit if you don't beleive me.
5%-15% quantity of Acetone being in 12oz container of fuel system cleaner that you run in your tank once every 3000 miles (read the can, you are not suppose to add a cleaner with every tank of gas), wont hurt a thing.
Regular gas ignites and burns more easily. Premium needs higher pressures and temps to ignite and burn thoroughly. A low compression engine running premium will not burn fuel as efficiently due to a slower burn rate due to the lower compression as when running on regular which will ignite and burn faster at a low compression. Different companies use different blends giving different burn rates but the same octane rating. Just a matter of matching the burn characteristic of your engine to the right fuel blend/company.
Low octane fuel like diesel burns really bad, you cant ignite it with a match, but pressurise
it ant it goes bang.
High octane fuel burns real easy, static electricity at the gas pump can start a fire, but
pressurising it wont do anything until you really put some serious pressure on it.
you said: "So what does any of that have to do with gas mileage going up when mixing acetone into your gas tank?
Nothing "
Oh geeze you must be real smart figuring out that! it`s called OT, i know OT when i see
it and so should you.
And to put it your way, what does your lecture about acetone as octane booster have to do with this topic?
Nothing....
You also said "Tons of documentation on the net to support that, goggle around a bit if you don't believe me."
You don't say.. does that mean that i can find it in my local newspaper too?
nope, I dont care to continue it. I know what an octane rating means to fuel in relation to how it burns in an engine. The higher the octane, the MORE resistant to combustion the fuel will be.
That is why high compression engines require higher octane. That way they can compress the air fuel mixture further without any risk of pre-ignition. If you compress a lower octane fuel, it *might* ignite on it's own while being compressed and not wait for the spark.
making a post to wikipedia and not really understanding it in simple english doesn't help make your case
However, adding acetone to fuel does not increase mpg. If you can't post a scientific study to show otherwise, then this thread is done.
You can smile all you want, its just a really childish attempt to cover your sarcasm, and
no way of gaining respect . Can you please quote where i claim that acetone increases mileage? no didn`t think so.. and no you don't understand what an octane rating means. Allow me quote a part the article you claim i don't understand
"It might seem odd that fuels with higher octane ratings burn less easily, yet are popularly thought of as more powerful. The misunderstanding is caused by confusing the ability of the fuel to resist compression detonation (pre-ignition = engine knock) as opposed to the ability of the fuel to burn (combustion)."
To put it more clearly for you, the octane rating tells how resistant the fuel is to *pre-detonation* and nothing else, meaning your claim about a connection between octane rating and ignitability is incorrect. Now there is nothing left do discuss, for either you or me.
I am sure your picture /post was meant in good faith. But have you ever known a special needs child or worked with them on a one on one basis? As far as I am concerned they are the most loving and caring people around.
Please refrain from posting something like this again.
