Yeah I believe it’s more of an maintenance deal. The leaded gas causes less wear on the cylinders and pistons, so generally makes the plane safer and less risk of a major malfunction during a flight. There aren’t many alternatives with similar characteristics to leaded gas. We used to use it in cars for the same reason, but decided the maintenance/safety/health trade offs were worth banning it.
