Alcohol is alcohol.  When you buy rubbing alcohol at a drug store, it is
usually a mixture, and is so stated on the label.  Alcohol will mix with
water, and stay in solution (won't separate like oil and water).  Yes,
there are different kinds of alcohol, like methanol, ethanol, and
isopropyl alcohol, but they are all available straight or as a mixture
with water.

Fuel dryer is alcohol.  Water will condense in your fuel tank and a
small amount will collect under the gasoline, where it cannot evaporate.
If you dump a pint of alcohol in your gas tank every so often, it will
absorb the water and allow it to be burned off.
