I'd burn it in a clunker. Water will settle so pour carefully into tank, and maybe dispose the last third or gallon even properly as hazmat if water is suspected.

Why not just add in ONE gallon each time you fill your tank, and burn it?

It is absolutely bad; I think it absorbs water from air?

Approved gas cans will work. I suspect they will empty them and return them to you.

Ah, so it is. The question is what do I put it in? Old milk jugs?

I've got about 10 gallons of bad gas I need to get rid of. It's in the tank of a car that's been sitting for nearly 6 years, and I'm in the process of getting it back on the road. I can easily drain the tank, but I'm not sure what to do with it once it's out.

I live in DC. I considered DPW's hazardous waste dropoff program, but they don't include gasoline on their accepted items list (they don't seem to prohibit it). Plus, I assume they'd only accept it in approved containers, which means I'd have to buy two 5-gallon gas cans and turn them in.

Any ideas other that lighting it on fire or letting it evaporate slowly?
