I'm about to start working on an old boat of mine that hasn't been used in a couple of years. It has about a 16 or 17 gallon gas tank and is fairly full. I'm going to siphon out the gas into a few 6 gallon containers to take somewhere to dispose of it. I know most automotive places accept used motor oil but I'm not sure where they accept premixed gasoline. Anyone know of businesses that do in North Alabama? Thanks.
