Re: What to do with bad gas?
I think his main question is "How do you "throw it out""? Can't just dump it in your sink, or put in glass jars and put in the garbage.
If it is really "old" or if you are unsure how old it is, find your local recycling facility, and ask who takes "hazardous chemical wastes" and when.
If 2 or 3 years old, I would mix with fresh gas and run through a lawn mower. not an expensive mower, but that hold hunk a junk out behind my garage. So I am only out $50 if it goes "KAPUT!"
If in doubt, though, play it safe, and find a recycler or hazardous waste disposal site.
