I have a 5 gallon gas can almost full of old gas that has outboard oil mixed in it. Its from a couple of my gas tanks that I cleaned out. I just had to rebuild my carb on my 9.9 so I wanted to start with fresh gas. Where can I get rid of this? I know where to bring my oil after I change my oil in my truck, but never had this much gas to discard. I don't want to put it in my weed eater or chainsaw for fear of clogging them. Any suggestions?
