sneak it into your old engine drain oil a qt or two at a time.
old used gas is a hard thing to get rid of.

let it evaporate slowly in pans.  ...polluting though.
burn a cup at a time of it in an older car, mixed in with fresh gas.

not something you want to get stuck with, really old gas in large amounts.
