    A partially filled tank breathes air when the temperature changes outside, and every time it does, a bit of water condenses inside.

      That’s true for diesel. First gen bio-diesel was hydrophilic to make that even worse. Absolutely fill up the tank before leaving it over winter.

      Gasoline keeps evaporating and essentially only breathes out until the tank is empty.

        Only if its hot out. The vapor pressure of gasoline below 20c is less than 1 bar
