I hope people are AWFULLY careful handling and storing this stuff if they
go this route.  My brother at a Shell Oil refinery tells me that when
people there work on the plumbing carrying tetra-ethyl lead, they wear
head to toe safety suits.  I can't imagine this stuff will be much safer.
It should be kept somewhere where it will not be accidentally spilled or
within reach of children, and safely getting rid of the empty cans or bottles
will be a royal pain.  (Remember, we're not talking about elemental lead, or
inorganic lead compounds such as found in paint.  This is a volatile organic
compound which is readily absorbed through the skin and is not particularly
healthy to breathe the fumes of, either.)

Certainly, anyone who has a "leaded" engine in this situation should give
high consideration to replacing the valves with hardened ones, such as
"Stellite", so that nonleaded fuel may be safely used.

A guy I knew once pointed out that way back when there was no such thing as
catalytic converters and just about the only unleaded fuel available was the
Amoco super unleaded, nobody ever seemed to fuss about valve wear with respect
to the Amoco gas, which enjoyed pretty good sales... I wonder why?
