 Yes they do. It is called Alcohol. It is Sold Commercialy in the
Coldere Climates as "Dry GAs" and under several other brand names.
 Since Alcohol likes top absorb water it does in the gas tank. In
the case of the Cold Climates of course it is to prevent the water form
freezing and blocking the gas lines.             
It would work for what you want also. But don't put more then 10%
alcohol in the tank. First that would be gross overkill. And more then
that will upset the Fuel to Air ratio and the running of the engine.
 Typical in the Cold climates you put a pint in 10 gallons of gas or so.
