The lead in the 100LL fuel will kill you just as miserably. That's why it
can't be transported through the nationwide fuel pipeline system, and why
oil from aircraft that fly on 100LL cannot be recycled like automotive
oil,
for example.

Horsefeathers.

My information comes from Ben Visser, of AeroShell/Shell Oil Products. He
has worked in fuels and lubricants for over 35 years, the last 20 of which
have been specifically in the aviation side of the company. He has chaired
the Committee and authored most of the SAE/Milspecs for aviation oils.

I wrote about this for Aero-News after attending one of his seminars at
Oskkosh. Because avgas has lead, it cannot be transported through normal
fuel pipelines. If that were to happen, the pipes would be contaminated with
lead and could not be used for other fuels. That leaves only two options,
rail or trucks, and both are significantly more expensive. In addition, the
additive used to add the lead content into the fuel is a known carcinogen
(and now only produced at a single plant in Great Britain). As far as oil is
concerned, the EPA has classified it as hazmat because of the lead content.
In 2004 it was estimated the cost of recycling a single gallon of recip
aviation oil was about $4 because of the lead content and its inability to
be mixed with other recip oils for recycling.
