[net.auto] Lead in Gasoline

Unless Congress intervenes, leaded gasoline will effectively
disappear at the end of the year. 
For those of us running old cars (pre-1974) this is real bad
news as our engines depend on the lead for proper valve seat
lubrication.

Any suggestions (short of engine rebuild) of what to do about
this???

while back.  The majority of articles seem to
indicate that perhaps some lead is needed for
old car valve lubrication but not the amounts
we use.  I also thought that lead is not
disappearing, just being dramatically reduced.

Ten to one you'll have to buy lead additives and add them per
fill.

This is a popular myth.  There is no controlled evidence that indicates
a problem using unleaded gas in older engines (provided the octane
rating is adequate). 

Even if you don't believe me, why would you rebuild your engine at
this time?  Use the unleaded gas and rebuild the engine when your
valves wear out.  

On the political issue:  I am not in favour of banning leaded gasoline.
It would be more than adequate to add a tax sufficient to make it
more expensive than unleaded.  This would remove the incentive for
the vast majority of people who now use leaded gas.

Concerning what can be done for pre-1974 engines after
the lead goes away.  I've heard from a reliable source that
those of us that give serious consideration to the longevity 
of our engines can purchase a lead additive that will supply
the necessary valve lubrication.  This stuff will only have to
be added every three fillups or so.  I will post details as
I come up with them.

Fluke.

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?

Better hurry and stock up before the EPA outlaws it as well.
