Has anyone found issues in older gas generators using the current ethanol gas. Ours is a 1999 Onan 5500. I'm wondering if I should have any concerns or look for any telltale signs? Chuck
In 1999, the Government had already stuck us with corn laced fuel. I am sure Onan was well prepared for the damage it does. I think you'll be just fine with the 10%******at the pump.
