I would siphon the fuel out into my truck or genny, etc. Hell I havnt bought fuel for my genny in 8 months. Once I found 2 5 gallon boat tanks full of gas. stunk to high heaven from sitting. So I dumped some stabil in it, let it sit for a day, and been running it ever since. Thats a safe legal way to dispose oif fuel. If running it into a fuel injected vehicle, I would recommend filtering it as some of the gunk cvan clog the injectors. Personally I dump the fuel in my truck and use lucas fuel stabilizer every 5k miles and no issues. And my Dodge is a oddball, no inline fuel filter from the factory. Only filter is built into the fuel pum,p assembly which is a 200 part. KInda f up idea from Dodge if ya ask me.

Yes I was a mechanic for years and years and I wouldnt give bad advice....
