Gasoline does seem to last longer in a gas can or car gas tank then it does in a lawn mower or motorcycle gas tank, I suspect part of it is the more stable temperature and better seals.
I have "fixed" countless motorcycles, mopeds, lawn mowers and snow blowers by replacing the "year old" gas.
In motorcycle owners manuals they always say to store the motorcycle with either a full or an empty gas tank, never half way or worse 1/8 full because you have a lot of surface area for moisture to condense and a lot of air space for vapors to form and escape.
A friend of mine who owns a motorcycle shop once said that fuel injection will kill his business because the sealed fuel systems nearly eliminate fuel related issues.
