Yes, 100LL still has lead in it. And despite what it may seem based on skewed figures from those who want to see local airports closed so they can build more strip malls and condos, there has been a 99.99% reduction of lead pollution from gasoline overall since the phase out of automotive leaded gas. We're working on getting unleaded avgas, you can blame the FAA for it taking so darn long, but it's hardly an environmental emergency. > Turns out most (all?) piston-engine driven airplanes still run on leaded gas Not technically all. There is unleaded avgas although it's not yet common and some piston planes are diesel.
