Preach. TEL is awful and studies have shown elevated lead levels in children near RHV. Where 1x0LL has been banned, the tendency has been to go to UL94 (STC & MoGas). The main barrier to another option, G100UL, that complies with ASTM D910 100LL, is that it hasn't been deployed anywhere, there's no fuel supplier (Chevron or GAMI), and it requires an STC for owners. Honestly, I don't see them ever deploying it. 100LL for the entire west coast is made only by Chevron and only in Richmond, CA. California's legislature may decide to ban TEL's use in fuel manufacturing, which would end LL in the western half of the US. PS: My cousin owns a bunch of helicopters, airports, hangars, heliports, and fuel bunkers.
