After reviewing Denny's jars of fuel I believe I would side with him. I too have seen "bad gas" in different application but feel that the problem came from contact with other materials to create the issue. Contamination from dirty fuel tanks, water in tank from time or cold storage when tank wasn't put away full, old rubber fuel lines, decomposing old fuel filters or cork gaskets. I still use Sta-bil but not as worried as I use to be.
