When I emptied the old gas out of the tank of my truck when I got it, I hoped it only had a couple gallons in it, but no it had like 12 gallons in it. I only had two 5 gallon cans, so it took me 2 trips to get rid of it. I had to take it about 6 miles across town to a shop that disposes of it by dumping it into their waste oil tank. The fee was only about $5, and I didn't have to deal with the stinky old gas that wouldn't burn anyway.
