Fuel oxidizes for sure and the rule has always been to winterize fuel to keep it fresh for the spring start but your fule will actually go tramp faster in the summer. I think one of the things that makes fuel sour in the winter is the condensation that can occur unless its really really cold. In garages there is a nice temp swing and if the air is moist you will get dew. The fuel Stabyl is a smart bet - its cheap and it won't hurt any more than the booze gas we have to use.
