This site claims that adding a small amount of acetone to your fuel can increase mileage and performance. Has anyone tried it?

Do a search on this topic. You will find that this may NOT be a good addition to the gas you put in your truck. The article sounds very convincing, but comes with a disclaimer if you decide to do the experiment. I'd be interested to see the results you get if you decide to try it.

 

I know a guy who put acetone is his tanks for better mpg, think he did 6 -8 tanks. He said his truck actually ran a little better, but he didnt get any better mpg and on a couple tanks he got 1mpg less.

Just something to think about.

 

Sometimes I go see Willie Nelson and help him make biodiseal for his Mercedes cars. It's always nice riding around in Uncle Willie's Benz smoking out with him. Or maybe that was just a dream.

 

As a chemist, I do NOT recommend this at all. Octane is a fairly heavy organic compared to acetone (polish remover). It is also partially oxygenated with a greater potential to burn at lower temperature and pressure. I would think that it would cause your engine to knock a little due to pre-ignition (compression). Well, I guess that it depends on how much you add too. The additives that "dry" or remove moisture from your gas tank are just organics that have the ability to dissolve in organic (gas) and aqueous (water) to allow the extra moisture to be moved on into the combustion chamber. My point being that these engines are designed to run on octane and are not muti-fuel engines. Adding ligher organics is not a wise decision.

 

Aren't there different percentages of acetone? I think it has to be pure 100% acetone to work.

 

Acetone is 100% acetone. Percentages are what you buy as in polish remover.

 

Hence why I asked. acetone(polish remover) isn't 100% acetone.

 

I guess if one whats to try it use only 100% on the label. So, yes, there are percentages of acetone mixed with various other solvents, but only 100% should be used.

Some will work better than others in the presence of acetone which is strictly a vaporization tool, rather than a fuel additive that alters combustion. The car computer still thinks it is running straight gasoline. None of your settings are altered. None of your engine parts are affected.

This was taken out of the reference above. This is not all true. Anything that is flamable will change the combustion characteristics since a mixture of fuels will behave differently than a single one alone. Yes, the acetone will help evaporate the fuel in general, but I don't think that this really helps. The octane evaporates well below the operating temperature of the engine, and in the presence of a slight vacuum. Adding something that evaporates more gas? Just does not make sense. Besides, if this were really true, I think it would have been well accepted years ago.

 

When I was a kid and could not find gas for my atv, I would pour dads paint thiner in the tank and use it. It ran fine...smelled a little funny. Then I would get spanked for using 25.00 a gallon paint thiner

 

 

i discussed wtih a former for engineer, he listed the materials used for seals and gaskets along the fuel lines, and what they could hold up and what they were succeptable to. acetone CAN and WILL damage a good number of seals along the fuel line, DONT DO IT, at least not for a prolonged period

 

I have tried this experiment (from the same site Johnk) with my 1993 Nissan Pathfinder and got 1 to 2 mpg improvement. I have ran 6 - 8 tank fulls with a mixture of 75 ml per 10 gallons of gas. This SUV has 112,00 miles and just passed Delaware emission inspection with flying colors. The inspector who did the sniffer test inquired (with a puzzled look) what year and how many miles. After my response his comment was that many of the new vehicles don't do as well as this one. Is it possible that running this mixture has cleaned the combustion chamber and is the reason for the results? My 2004 FX4 runs on Sunoco pump gas only.

 

Good to know. I feel that running a very diluted amount of acetone through and around seals in the fuel system will not cause any damage, but anything over about 10% would. Acetone is a fairly agressive solvent on many plastics and rubber materials. As for this above quote, maybe I am wrong. A little bit of anything probably will not hurt, but I am still skeptical. I am guessing that a little fuel system treatment with about 100K would give you the same result. I also find that adding a little bit of acetone to the tank at each fillup is a little bit a hassle. Anyway, do what ya want, but I think that a little more R&D is needed.
