Any ideas on this guys? Would you have to rejet to see the improvement? would it wreck seals in the carb bowl??

RW, are you going to try this? Make sure to let us know your results.

I don't believe Acetone is good for your tank, your fuel system or will do what they claim.

That said..... if someone here does try it.... let us know.

stay within posted speed limits....

stop aggressive driving...

avoid unnecessary idling...

combine errands....

From NPR Car Talk in 2006
Dear Tom and Ray:

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 percent 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. I am NOT knowledgeable in the workings of engines, nor do I have knowledge about fuels, so I can be snowed by people who may or may not know what they are talking about. I value your opinions. What do YOU think about this? -- Wil

TOM: It's bo-o-o-o-gus, Wil. With four "o's." Don't put acetone in your gas tank.

RAY: It does absolutely nothing to increase your gas mileage. 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 also 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, pouring 100 percent, undiluted rubber-eater right onto that tube, you'll be eating through it in no time.

TOM: Here's our final reason not to use it: 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 have posted this before and will again.

Acetone has basically the same BTU content as ethanol so how can it increase efficiancy that much.
acetone is used in methanol drag racing to prevent phase seperation of the gas and methanol and any water which is attracted by the methanol. All are kept in suspension with the addition of acetone.
10% ethanol does this very slightly, seperation/water attraction, higher % will act more like the methanol.
so if one is getting bad mpg due to phase seperation then yes adding acetone will increase mpg, otherwise acetone does nothing!!

There was a thread about this very subject maybe a year or so back.

Acetone is a strong solvent that may damage some components in the fuel system.

It doesn't make any difference in the dilution of acetone and dilution will only take more time for the same outcome.

Toluene is a recognized additive to raise octane of gasoline, but it's doubtful that any increase in mileage would warrant the increased cost of the chemical.

I did a very extensive test of acetone a few years ago with my Nomad..  About 1k miles with many different concentrations.  Results  Nothing.  No good no bad.  It is a waste of time.  I have the data if anyone wants but the results were obvious.

[1fastbob]

I did the acetone test 2 years ago on our brand new 2008 Honda Rodgeline.  First try I got 12.5% increase with a few ounces acetone in fuel tank.  I tried again and was unable to reproduce the results.  At work we keep about 400 gallons of 75% xylene 25% toluene mixture.  One of these days I will try a few ounces of that.  I doub't that acetone will cause any problems with just a few ounces in 15 or 20 gallons of gasoline.  There are a couple of fuel additives that contain acetone in fairly small amounts.

just my 2 cents

[Rio Wil]

dang.....i thought this might be perpetual motion for the fuel tank....

[John G.]

I agree with Hubcapsc with one additional comment.  Only burn gasoline that is ethanol free. It is still out there and my increase in mpg matches the BTU increase of no ethanol.  The increase exceeds the price difference for the real gas.

at 10 dollars a gallon i dont think treres much savings here anyway
