Yes you can. You can also put water in your gas tank but it isn't a good idea. Really the question I think you are asking is whether acetone improves gas mileage. Whether it has any long term effects is still debatable.
Acetone molecules evaporate when you add heat to a beaker of liquid acetone.
add gas or it may be a faulty gas tank.
Acetone is usually a liquid.
no
your gas tank
no
You add it after filling your tank. Just open n pour into where you usually fill the gas.
Acetone in the gaseous form (when liquid acetone evaporates).
Add isopropyl alchol
No, because when you add acetone to acetone, all you are doing is adding more of the volume of acetone to acetone. You are just changing the amount of acetone, not anything chemically happening.
take off the gas tank and then find a small chain, put the chain inside the gas tank add some gas and shake it for about 2 minutes, drain the gas and repeat if gas was orange or until u get it clean.
add 2 ounces of acetone per 10 gallons fuel in gas engines. add 1 ounce acetone in diesels per 10 gallons. you should see 10-20% better mileage with just this simple additive. you can also add on a hydrogen generator.
