We added lead to the avgas to obtain the octane/anti-knock properties, and I’m not sure how this might affect catalytic converters or generator exhaust systems. And yes, avoid ethanol in small engines with vented fuel tanks.
The avgas I ran in my previous carbureted Honda generator was recycled into my Atv’s as they did not have catalytic converters , and yes thank you for pointing out that Avgas cannot be safely used in autos designed for ethanol.
