My car's check engine light kept coming on. Finally found a tech that figured it out at the dealer's. He said vehicles are coming in with problems due to more ethanol being added in the gasoline. Ethanol will eventually corrode the engine. He reset the light and said use non ethonal gas for a tank and see if the light comes back on. It's been three tanks full and no light. DH filled up with the gas we usually use and the light came back on. Why is this stuff being pushed as better? Better for the people that make it.
