You're mostly correct. It was an additive to raise the octane rating and did lubricate. However, it wasn't a gas refinement issue that caused the need. An octane boosting additive has been needed ever since, right up to today. Now the octane booster used is ethanol, mostly.

Race cars and many airplanes still use lead. We're still making people dumber. Just at a lesser scale.

If you want a sad rabbithole, look at the cancer rates around small airports, which are often much closer to where people live.

While it’s no consolation to these current people, they are trying to make the switch to lead-free aviation fuel. It’s partly a regulatory nightmare, and partly a genuine safety challenge; mandating a fuel change in aviation without adequate research and understanding can result in unexpected engine malfunctions.

unexpected engine malfunctions

On the other side of that is the known problems that lead causes. Seems to me that the best solution is to give everyone a cut off point, and say, hey, when we hit this point, you're going to have to retire that engine, and get one that's known to be good with lead-free avgas. Sure, it's a cost, but that's why you give people time to prepare.

They have! 2030.

I’m not sure if it’s a mandate, or a goal, but it’s there.
