On a somewhat related question, what do you do with "old" gas? I have some chain saw and outboard motor fuel from years ago. I have looked for recycling stations, which do take oil, but they won't take old fuel. I have heard some say to just pour it into a metal pan, like an oil drain pan, and burn it up, a little at a time, in the driveway or open area. Maybe with a large fire extinguisher present, but I don't know. A neighbor said he puts it in his truck when the truck's tank is nearly full, so the gunk and shellac is diluted enough and it can burn in the engine. Sounds like a way to plug a fuel filter and lines to me, but I might try that for a few ounces at a time. Other suggestions? Thanks.
