We're finally able to start reducing that. Just last year, the FAA approved the use of unleaded aviation gasoline in all spark-ignition aircraft designed for 100-Low-Lead.

They've also fairly recently authorized compression-ignition ("diesel") engine swaps in some of the most popular piston-powered GA aircraft, allowing them to burn cheaper, more efficient jet fuel instead of gasoline.
