I was listening to an AM 1100 coast to coast radio show and a man was saying that one tablespoon of acetone to every 10 gallons of fuel will increase fuel economy by 20 to 30 percent.
Is this a safe ratio or not safe at all?

Check out Episode #53 of Mythbusters on fuel mileage scams. They tested myths on increasing mileage via 4 methods. One of which happened to be acetone. They tested it on both carburated and fuel injected vehicles with absolutely no increase in gas mileage. I just wish they would have taken it a step further, ran a car on it for several months, then opened the motor and looked for damage. I don't know why so many people really think this works, but hey, better them destroy their vehicles than me.

It is a scam. Several of us gear heads tried this a year or two ago... doesn't do anything to your mileage in most cases.

If you drive a pick-up, just remove the tailgate. You will get better results and it won't cost you anything to replace all of the rubber seals/O-rings you destroy. Oh ya, drive with the cruse set at 55 also. This helps.....deadeye

Myth: Driving your pickup with the tailgate down gives you better fuel efficiency than with the tailgate up.
Test Setup

Adam and Jamie were each given identical, new model pickup trucks. They both had equal mileage, same tire pressure, and 30 gallons of gas. Jamie drove with the tailgate up and Adam the tailgate down.

The rules:

1. They have to maintain the speed limit 2. All acceleration must be done by cruise control 3. No drafting 4. Windows up, A/C must be exactly the same in both cars

The Test

After 300 miles there didn't appear to be much difference in the gas consumed, but after 500 miles Adam (tailgate down) ran out of gas. Jamie made it another 30 miles before he ran out of gas. This result was the exact opposite of the myth.

Actually I think you need to leave the tailgate in to get better fuel milage. Add a hard bed cover to get a mile or two better. There were tests done on this subject and with the gate in there was an air pocket in the bed and the jet stream moved over it easier than without the gate. Not my experiment just what I have heard several times and read a few times in Motor Trend's off spring Truck Trend.

I drive w/ my tailgate down all the time, and I get about 2-4 extra mpg. I was getting about 14-15, now I get about 17-18 doing my regular daily driving w/ an '88 F150

I used acetone once a long time ago to dissolve gelled gas. Worked--it dissolved the gel but it also dissolved the fiber gas filter. I had to clean out the carb several times before getting all the little fibers out of the system.
Swore off the stuff.

While it's true that acetone will dissolve some plastics, so will gasoline. Some info on this subject at:

Ever notice that some folks will say acetone works just fine and then don't have the gonads to sign their name. And then on top of that say something stupid like, 100% acetone does very little damage to rubber. I've said this once, and this will be my last time so pay attention here. Drop a plastic object, {your favorite ball point pen will work} in acetone and see what happens. {ball point pen injected engines are not subject to this test} and I do understand that all plastics are not made equal. Now drop your favorite color "O"ring in acetone and see what happens.{for us dummies that do our own maintenance, we have to think about the O"rings that seal fuel filters, and the plastic fuel lines under our cars and trucks not melting from acetone while setting in the garage or driving down the hiway } Now think about this" If three or five ounce of acetone in ten gallons of gasoline will up your milage, then how bout? nine or fifteen to ten gallons and really get the old rust bucket earning it's keep, or maybe a gallon of acetone to a tank will get you plum cross country? This BS never stops, so do the test. and remember, there are "so called" smart people that do dumb stupid things, and then try to convince others to do the same, they can then say they wasn't the only dummy that screwed up his ride....SO DO THE TEST... And it's been said rat here by some on YT, that it boost's Diesel engines as well. So those of you that rebuild Diesel injection pumps,{this is a money maker if there ever was one} dump a few of your old {or new} used injector pump seals in acetone, red seals, black seals, whatever you got, and see what happens... And I know that dilution is ticket, but it's kinda like telling a drunk when he's had enough. So do it if you will, but save your money, you gonna need it for repairs later..

Been using it for about a year now. Pick up about 4 mpg in my Accord and 6 mpg in my del Sol...

3 ounces per 10 gallons works great. And people have tested 100% acetone on the rubber fuel parts that supposedly are ruined by it - very little damage at 100%. Also testing 50% concentration and there is no noticable damage to any parts.

Stop being so skeptical. There was a time when fuel injection was just a "crazy experiment" that would never be practical... same thing with automatic transmissions, etc.

So you think you're getting better mileage. That's good. Now if someone can show me some certified dyno tests, they might make me a believer.

Don't go comparing acetone in the gas tank to fuel injection. One is a an engineered solution that has been in development for over fifty years. The other is just a kooky idea.

I took a look at some of the web sites devoted to the acetone idea, just out of curiosity. The theory seems to be that acetone changes the surface tension of the fuel and makes it vaporize better. I don't know how you expect to vaporize fuel any better than shooting it out of a fuel injector directly into a hot intake port. This whole thing smells a lot like the old "vaporizing carburetor" legend. Modern fuel injection put a stake through the heart of that fable, so someone came up with the acetone theory.

Acetone dissolves gasoline gum about as well as anything, so it is good for cleaning stubborn places on carburetors. Fuel mileage increase- I don't believe it. It will for sure ruin most of the "rubber" parts of the fuel system.

Somebody check a can of 'Gumout' and see if it's a listed ingredient. Maybe check other cans of fuel cleaner- Sea Foam, Gunk, whatever.

It works but not at those percentages, at least I didnt see it. I added some in a gallon of diesel then poured it in my tank and saw only a slight increase, but my truck ran a tad bit quieter on it.

Actually... there are some people using it, and they are claiming real benefits, but the ratio is 3 to 4 oz.per 10 gal.and it won't give a 30% improvement.
now before you all start jumpin on me,lol , these are regular folks with regular driving, and having done nothing else but add the acetone, SOME have had a noticible difference, and SOME have had no improvement. Apparantly it depends on the type of engine,vehicle, gas blend, and who knows what other factors.The best results were about 2-4 mpg increase, which was confirmed by stop adding the acetone, then starting again for repeatable results.
There is a web site that is supposed to explain the chemistry, but you'd have to do a search to find it.
All I can say is these are real people that I have contact with, at a forum like this.I guess you won't know, unless you try it yourselves. Now, let the scoffing begin,lol

You find that on the BS of the day board?
I frequently use acetone as a surface cleaning solvent before top coating difficult alloys. I'd say a tablespoon of acetone likely wouldn't make it down the filler tube into the gas before evaporating.

Nonsense. Energy is, well energy. That teaspoon of acetone would have to be nuclear to increase mileage or lower fuel consumption 20-30%.

$4.50 a quart at ACE. The chemical additive that it's supposed to nutruelize, is a EPA required additive, begins with the letter "M", can't think of it, but is also a known carcinogen, and kills fuel economy.

As I understand it, works well in premium grades (no ethonol), not very well in midgrades, not at all in regular grades. Provides a more even and thorough burn through the combustion chamber. Understand is more like 2.5 ounces per 10 gallons, and the percentage gain in HP and fuel economy savings more than offsets the 20 cents more per gallon.

Rusty's right. Too many people start doing it, acetone will go to $10 per quart, or become illegal. Funny thing, folks can't afford gas to heat their homes, so turning to wood burners. Wonder how long before huggers will stop that too? If it's helpful, must be portrayed as evil and be banned, or become so cost prohibitive, may as well be banned.
