Water Carrying Properties of Alcohol Compared to Acetone

Adjunct to Directory:Acetone as a Fuel Additive page.


The water carrying properties of alcohol and acetone are essentially the same. One drop of water in many gallons of either alcohol or acetone will completely dissolve. Similarly one drop of acetone or alcohol in many gallons of water will completely dissolve. Neither can be seperated again without major effort.

Obviously the amount of damage to fuel system injectors, etc. is porportional to the amount of water, right on up to pumping pure water through them.

3.5 ozs acetone per 10 gallons gasoline is about a 0.3 percent concentration. ethanol gas contains up to 10 percent of alcohol.

NO damage to fuel injected engines is cause by 10% ethanol else it would be forbidden on the market.

Therefore the same will apply to acetone concentrations up to 10%.

There is no difference in combustion products from acetone compared to alcohol. Both are made up of carbon, hydrogen, and oxygen.

Therefore, the water damage done from 10% ethanol in gas will be 50 times worse than that from .3% acetone, as is plainly obvious, and BOTH will depend on how much water you have in your tank from contamination. The alcohol will carry away tank water 50 times faster than the acetone in the concentrations usually used. In the usual trace amounts of water, the ethanol gas will corrode things 50 times faster than acetone use. NEITHER CAUSE ANY PROBLEM, for ethanol gas is used everywhere, and no problems are known to the government or it would prohibit sale of ethanol gas.

As for diesel, without getting into the 57 reported mixtures of disel used in USA, you can be sure some diesels have water carriers similar to acetone or ethanol in them, with NO trouble reported or the mixes would be outlawed. Thus any worry about diesel is trival, and about gasoline is zero.

Therefore I would ignore worries that using acetone in gasoline would cause injector or pump damage. The numbers simply nullify that worry.
