The engines don’t require lead, it was just the only high octane fuel available. We do have a 100LL replacement now, and work is being done to get it into service. Lower compression engines run just fine on mogas where it’s available too.

  The engines are fine with ethanol. The problem with ethanol is the issues related to it eating at materials in the fuel system (e.g. fuel lines) that aren't alcohol tolerant.
