Like others have said already, there's so much BS on this subject it's ridiculous. I have run it many times in cars or motorcycles in the last 45 years. It always et's better than pump gas for me. I haven't seen any ill effects. Years ago avgas was better but at Keith Blacks that is what we used on the dyno.
Does this mean it does not hurt valve seats?
I know of a place that sells race gas for 25 years or more now and it's Av gas and always has been and they have a dyno and airplanes and a drag strip too.
