Exactly. The idea that you can't make an engine that runs on unleaded is rediculous. Airliners for example don't use leaded. Yes, planes 50 years ago -> maybe

Exactly. The idea that you can't make an engine that runs on unleaded is rediculous. Airliners for example don't use leaded. Yes, planes 50 years ago -> maybe those were designed for leaded. But the idea that we are selling new planes, today, that "only" run on leaded gas is a farce and goes to show how seriously aviation is taking the transition away from leaded gas (which has been delayed as I've said decades). At some point you just lose patience.
