My "Tennessee Linemen" asked if I had any gasoline and I gave them the can I use for the lawn tractor containing about a gallon. When they gave it back to me, they warned my wife "tell your husband not to use it. It'll ruin his engine!". I was in the house at the time. Two questions. 1. What is in there? My guess is two-cycle mixture for the chainsaws they used to free up the power line. 2. How do I get rid of it? By chance, I do have another gas can (metal - very heavy, Army Jerry can) and I suppose I could pour the mixture into that, still leaving me with two problems: Where do I dump that, and more important, how can I clean the plastic gas can to get rid of the residue that I'm sure will gum up my engine and fill the air with oil smoke? Luckily, I don't use that gas in my car with fuel injection. Bye bye injectors. BTW - my landline is still down, buried under fallen trees.
