The issue is that while cars only have ~15 year lifetime, small general aviation aircraft have ~50 year lifetimes.

Not particularly relevant to the lead debate though as the engines are replaced after 1,500 - 2,000 hours and retrofit Diesel engines running Jet A are available on lots of aircraft (but people don’t buy them as they’re expensive and heavy)
