Got evidence of that? The EPA's position is and has been that leaded aviation
fuel doesn't constitute enough of a hazard for them to target it, and the fuel
experts at the Oshkosh symposiums said that legislation isn't a problem. They
said that what will kill 100LL is the fact that the market is declining and the
manufacturer of lead-tetraethyl will almost certainly find it unprofitable to
make it within the next 8 years.
