Gas goes "bad" after a few months. Small discplacement high compression engines are more prone to be affected by it. If you run a tank a month, that's not a problem, but if you go beyond that I would buy a bottle of "Stabil" (fuel stabilier) and also buy a bottle of gasline antifreeze to remove any water that may condense in the tank.

Both water in the fuel and stale gas will affect your car negatively.. the stale gas over time will damage your fuel system and the seals associated with it.

take the advice or not... ask any motorcyclist and they'll tell you the same.
