There's a whole bunch of crap online that advocates adding acetone to your tank o' gas.
I'm not sure I want to put a solvent into my car where there are plenty of rubber seals.

Why would anyone use acetone when they can buy mpg-caps?
Which, according to a report on last night's news, is currently being investigated for fraud by at least one state Attorney General.

Gasoline often contains a smidgeon of Acetone but not by intent.
We've mixed a lot of different cocktails for our kart engines over the years acetone included. It will not boost mileage and it will attack Butyl Rubber.

I've been running acetone in various vehicles for about 2 years now with no ill effects and about 5-10% better mileage. For whatever reason, the trend is that it works best in summertime, and begins to lose effectiveness in the cold months, due to some change in gas formulation. I have been running it in my FC as well. In the percentage the acetone is mixed at, there would be no harm to any rubber in the fuel system.

Well - I learned something.
I'm going to try it at 2oz/10gal.
The octane boost should allow me to run 87 in the Caddy.
It's a '94 "use premium fuel" Northstar.
It likes 93, but will run OK on 89, and gets lame with spark retard on 87.

forget acetone, go buy a gallon of toluene (114 octane) or xlene (117 octane) from a paint store. 20-30% of gas is aromatic addives as it is. if you want a octane boost a gallon of those to a tank will jump you 5-10 points.
the only thing acteone does is dissolve gunk, and to some extent reduce surface tension/foaming . it works in the short term or if you have crappy gas with a lot of crap in it that's leaving deposits and clogging injectors etc.. it is not a magic mpg booster it just dissvolves the crap bad gas can put in you car.. and most of your seals too.

When in doubt look for RG, swoop, team, Richard, mysql101, or one of the other big wigs. Only one of them has chimed in so far.

Still wandering around their forum. On of their big wigs is also anti-acetone.

The vapor/surface tension "thing" just doesn't hold up for about 12.5 reasons (basic, surfactant chemistry). :"They" had the same "discussion" back in the 80/90s when gas was expensive (supposedly) and catalytic converters and oxygen sensors were starting to come in to use.
FYI: The acetone is reacting with the catalyst used in the oxygen sensor making the mixture appear" too rich. As a result - the mixture is leaned out by the computer thus the mileage goes up.
The reason it does not work the same on all cars is that there are three different metals used as catalysts in O2 sensors: platinum palladium rhodium or in combination. Acetone in combination with NOx (and others) in the exhaust will react differently with each metal to either speed up or slow down the catalytic reaction of the oxygen senor. FYI, I am not talking about the catalytic converter - just to stop about 100 posts.
Question: am I the only one on the planet who remembers this? There seems to be a lot of people skiing behind the "vaporization" boat?
The reason I know this is that I used to work for Exxon; and fyi, the reason they don't put acetone in gas is that it is hard to get it to stay there and second over time it reacts with different kinds of additives in fuel. Which is also a reason why it does not work on some cars - it's the gas not the car.
They have had additives in the past with acetone - old news. It is good that it works though! It simply had gotten more news because of the historic price of gas.
Also, this is why ASME standards for elastomers used in cars requires (heavily suggests) that all elastomers be tested with acetone - along with other (i.e . MTBE, M85 ...) Once again, very old (but good) news (remembrances)

I would wait for one of the old wise ones to chime in before trying this.
I don't plan on doing this. The cost of gas saved vs what happens if it messes something up just doesn't seem worth it.

I personally think that putting random crap in to your gas tank is not a smart move......remember when there was a hype about putting sugar in your gas tank?

I researched it and everything I find says it's safe and will increase gas mileage. Here's a link to a company that sells a vapor inducer kit with reservoir just for this purpose.

my dad did this a few years ago in his old Camry he was getting ready to junk anyways. He mixed a 2 OZ per 10 gallons as well. His mileage went from 27 or so to over 30. He was so happy he kept for a few more months until he run over a curb and blew out a shock and it was too expensive for repairs than what the car was worth and junked it.
