Gas doesn't go bad as fast as people pretend. Yes it has lost a bit of octane rating sitting around, but unless you are driving a 30+ year old performance engine with high compression your car isn't going to notice the loss of a few octane points. Anything within the last 15 years measures and adjusts for fuel octane rating automatically and won't care, and anything non-performance that is older was designed expecting fuel octane to be lower than what it is sold as. Also these days most places add 10% ethanol to all pump gas which has a higher octane than gasoline and is replacing some of the old high-octane components of fuel that evaporated and caused gas to go bad sooner.
