I have a small amount (less than a gallon) of gasoline that's been in a can for two years. It has oil mixed in for 2-stroke engines.
The can sprung a leak and rainwater leaked inside. Probably only a teaspoon or two, but I can't know for sure.
How to get rid of it? Should I burn it off? Can I just mix it with more gas and use it?
I found a good, unorthodox solution. I stored my gas cans in an unlocked shed in my back yard. Someone came by and stole them! Your mileage may vary :)
