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
Hi Chuckbear, I to have a 5500 Onan generator.I do all my own service.I have found that if I ad a bottle of seafoam or stabul to the tank once a year and run the generator at LEAST once a month with the air cond on ,I have not had a problem ever. I even run my gen when going down the road to help cool the inside down,A Generator is made to run.
