We had 1 place left in town that did not have ethanol in their fuel, but I havent been by there in a while. I heard that its a federal mandate for gasoline to have ethanol in it now. Is this correct?

Ethanol degrades and pulls the plasticizers in things like diaphragms and the inside of fuel lines, thereby causing them to harden and no longer perform.
