How nice would high octane gas be?

O.K...if it had water problems the fuel has sat too long and has gone bad.I have read it should be used within 45 days or even less where it is humid.

Correct, however this is a added property, as it is an inerrant property of ethanol, to both separate from petroleum based gasoline, as well as draw moisture from the air. Pure gasoline can sit significantly longer with little or no effect.
