if the color changes or not. but i would get some out and look at it. it will under some circumstances get gummy. of course it will probably not smell like gasoline should either. i dont really know what i would be looking for, but if it came out good and liquidy then i would think draining it and adding more would be ok. if it were really gummy then i would prob take the tank off and get it cleaned. if it were, say, 1/3 full and good and liquidy and didnt seem too smelly i might just add gas and go for it.

good luck
