I've never yet been able to find anyone who will take bad gas. I sometimes end up with a gallon or two of old 2-stroke mixed gas after a season, and I'd rather get rid of it than take a chance of plugging up my carb in the spring. Ethanol just makes this problem worse. I live in a city where I can't just burn it off, and the whole area is now no burn anyway. What do you do to get rid of bad or old gas?
