you know what....I have a neighbor I don't like very much......

I think I'm going to try it on his car and see if he gets good gas mileage....without any problems.....

:lol: :lol: :lol:

I'd be a little weary of adding something to my gas like that. I know it's a highly volitule liquid, but I'm a little skeptical.

Sounds like snake oil to me. I think it's possible that the acetone may function as a fuel system cleaner by dissolving contaminants. That, along with a nice placebo effect, probably does something.

Edit: Never take advice from a Wiki that describes acetone as a "colorless, volatile liquid with a sweet odor."

Or from people who claim that "ounces per gallon" is not a ratio.

 

Waaa gas is $3 a gallon... Just suck it up and pay. Local news here is always talkng about wacky things to improve milage. Either get a smaller car or dont drive at all.

 

Yes, it raises your octane level also, BUT they forgot to mention that acetone also DISSOLVES rubber products.

Now, let me know if you want to put it into your car and also let me know when I should send a tow truck to pick you up.

Good luck

Hey if its a trick that works, like mixing xylene or toluene and marvel mystery oil into gas when racing fuel isn't available (also has the same concerns but people have been doing that successfully)... Just throwing it out there to see if anyone actually had experience be it positive, negative, or that it simply doesn't work. From what I've been reading, the results are pretty positive (which is an interesting discussion about WHY that works regardless... any PEs in here?), but the safety of the fuel system is a concern obviously. I wouldn't try it myself either unless there was someone with my specific vehicle that has been doing it for at least 15months +.

Thank you for this gem of a contribution...

 

Im pretty skeptical of this doing anything, sounds like that stupid "tornado fuel saver" idea that really doesnt do anything

even if it does help, I wouldn't put it in my car

 

Guess I am bringing this topic back form the dead. A matter of fact I have been using acetone in my tank for over 2 years in all my cars. I usually mix an ounces or 2 for a fill up. I get my acetone from a local beauty saloon, just make sure it is 100% acetone. It does increase fuel economy, but don't expect 50mpg.. maybe +5mpg or something like that.

 

It also increases your fuel octane. For me I'll just use Torco. Good luck

Torco? I thought they make oil only?

 

Here's some info on the wonder of acetone..

Most octane booster contain acetone.

 

I don't understand why people think acetone will damage the engine... you are not suppose to pour the entire bottle at one go.. I add an ounce or 2 when I plan on traveling long distance. no problem what so ever... damn Oil company is BSing every one so no one uses it.

 

I coulda sworn on myth busters they said it was a flop. I see it as this, if it gave a decent enough mpg boost then all gas stations would have it blended with their gas and market the heck out of it.

Ive seen people try hypermiles with alot better success than a fuel boost. A friend of mine got 55 mpg in his 94 civic on the highway by driving at 50mph the whole way. Itll boost rating on all vehicles but staying under 2k rpms can get boring fast. Cars today its all about how the fuel you have is spent rather whats in the fuel to boost mpg.

Depends on the vehicle...

Acetone does act as a surfactant just as most proponents claim. It can help increase milage in carburated cars too because of that property.

Problem with modern fuel injection is that the injector still squirts the same amount of fuel based on the ECU. Now that fuel that has been injected will be in a somewhat finer spray and will have somewhat more complete combustion, but it's till the same amount of fuel that the injector would inject without the acetone.

 

If you get more energy out of each squirt though, economy should go up, which is why economy drops slightly on E85 since the ethanol has less energy than gasoline.

And I believe those ultra-fine mist fuel injectors have come out now to also assist in improving fuel economy, and at the very least I know that dirty injectors that don't spray a fine mist do make worse power and hence worse fuel economy.

Not saying I buy this stuff though... cuz while water has really high surface tension, I don't think gasoline is nearly as bad. When I get home, I'll try pouring some in a small cap and see how much of a bow I can get the gasoline to make compared to water when its filled to the top.

 

You pay next to nothing for fuel in the states anyhow. Try living in the UK and getting stung for the best part of $2.00 per litre

o2 sensor?


If combustion is more complete wouldn't the ECU reduce the amount of fuel injected based on readings from the o2 sensor?

 

Acetone is not a miracle additive that will increase 50% fuel eco. I drive from Windsor to Toronto alot (3.5 hours drive), so before any trip out to TO I put a bit of acetone in it. I cruise all they way out, and the different of having and not having acetone is noticeable. (with today gas price $1.10/L, I probably save like 6-8$ per trip?)

I am not so sure about city driving, but hwy driving I can speak from experience that it does help.

Good point. Though it might try to inject more fuel in an attempt to "fix" a "lean" condition. :dunno:

I've never tried it myself... maybe I should.

 

Well, I may get scolded for this, but here goes.

Ive tried this before, well because I like to experiment and I go into any experiment fully prepared that it may cost me, but I get compelled to try sometimes and this was one of them.

Acetone in the quanities that they suggest (start out at 3oz/10 gallons) is not sufficient to cause any damage to any rubber components in the fuel system. Nearly everyones experience with acetone is in its full strength form and this isnt. There was even a product on the shelf at one time that was sold as a fuel system cleaner and fuel economy improver. I cannot remember which one it was but all it was was acetone. I'll have to see if I can find that again but the name escapes me now.

Anyway, I tried this in my Grand Prix GTP with an 17.5 gallon tank. I worked out how much to add based on 3oz/10gal and did that for two tanks and never noticed anything. I keep meticulous records of my fuel mileage. I have every receipt for every drop of gas I have put in that car and on each reciept is the trip odometer and main odometer readings and the reciept gives me the gallons used. I then enter that into an automotive maintenance program on my PC that among other things, tracks mileage.

Anyway, I tried 3oz/10gal for a couple tanks, 4oz/10gal for a couple tanks and 5oz/10gal for a couple tanks and I never saw any mileage increases. I came to the conclusion that either A.) it doesnt work or B.) because I have to run premium fuel due to the supercharger that it would take more acetone than I had tried and I was just kinda put off by it at that time. Higher octane fuels burn slower and because of that would probably take more acetone. You normally will see a drop in fuel economy with higher octane gas, but it is good at helping control knock. Lower octane fuels usually exhibit higher fuel economy, burn faster but can induce knock because of that characteristic. Im also running pig rich at the track so that may have played a part in it too. I have a tuner for the computer, I just havent had the time to get it all done yet.

So at least in my testing, I didnt see any benefit. But if I ever get a car again that doesnt need higher octane fuel, I'll try it again and see if my theory holds true.

I will tell you something that does work and Ive have used this on both the Focus and Grand Prix. That is sidegapped spark plugs. Pure copper core (no platinum, irridium or any other exotic metal) plugs. Think Im crazy on that one, I can show you some high end, money making racers that use this technique.

 

What program do you use to track your maintenance?

I too have tried the Acetone, saw no benefit to it over 3 tanks, stopped using it.

 

sounds like the old moth balls in the tank trick.

I've never really felt that cheap prices would justify not wanting better fuel economy.

 

sounds like the old moth balls in the tank trick.

I used to blend/package fuel additives for a fuel additive company here locally almost 10 years ago. The 2 main ingredients in their product, that supposedly cleaned injectors and increased mileage, is a white flaky powder that reeked of moth balls, and mineral spirits.

The product was eventually contracted by X1-R, bottled and packaged by us then sold nation wide. It was crap. :lol:


And please, don't ask how I know what moth balls smell like.
