Do any fuels presently available for piston-engine general-aviation
aircraft contain tetraethyl lead as an additive (it's an octane booster)?
If so, are there any deadlines with regard to the phase-out of these fuels?

I know you were able to buy "LL-100", meaning low-lead 100 octane, up to a few
years ago.  Does wonders in a car with a knock sensor so it can take advantage
of the extra octane points, but it isn't a good idea if you have a cat.

Don't know about phase-out, if it's happened already, or what.  The AvGas
was pretty expensive, though.
