But for the most part bad gas was a problem that affected people like farmers and antique car guys who let things sit for a long, long time then tried to take a short cut by not cleaning the old fuel out of the tank or engine before they tried to bring some piece of internal combustion equipment back to life. That was the old days. These days bad gas has become everyone’s problem. The addition of Ethanol to automotive fuel has changed the gasoline game for the worse. Ethanol-enhanced fuel has been causing serious problems in both large and small engines.
