Back in the 1970s when we switched to unleaded gas, what did the vehicles that ran on leaded gas do?

Did they have to track down leaded gas? Did they just use unleaded? Did they suffer engine knock?

It's pretty uncommon though. Aviation uses far, far more leaded fuel than classic cars.

Yeah, I knew that some planes still use it. I have had a full year or so now of being horrified by that too.

I wonder if we're still going to be selling PFAS 50 years from now too.

Only small prop planes, and not all those.

Almost all commercial aviation are jets or turboprops, using jet fuel. Jet fuel has no lead.
