I've read a few articles recently about winterizing. They actually suggest keeping your tank about 75-90% full. The reason being, It keeps condensation from entering your tank.

I've heard the age old myth that ethanol draws moisture. The fact is that moisture BONDS to ethanol molecules. So, the less moisture and condensation that is allowed in the tank, the less chance there is of phase seperation, and moisture related problems.

Another benefit is that there is rust and oxidation inhibitors in fuel. An old 'bolt has a steel fuel tank. So what happens to bare steel? It rusts. An empty tank left open to condesation is just an invitation to rust.

BTW- The main ingredient in Stabil IS Alchohol.
