Tetra ethyl lead was used in gasoline to boost octane back in the day before it was banned as toxic. That spelled the end for high compression muscle cars with 10:1 and 11:1 compression ratios. Since then other octane boosting additives have been used, including ethanol, which is the main one today. Ethanol also satisfied the environmentalist and agriculture lobby groups and farmers were subsidized. But those old muscle car engines also needed the lead additive to lubricate the valve stems, so they needed other additives. Avgas still contains lead because safety and performance trumps environmentalism in the air.
