Hi Bill,

A question on the unleaded issue.  I DON'T WANT TO IGNITE A UNLEADED/LEADED
FLAME WAR DEBATE!!  You never know, some of the fuel just might ignite and
destroy us all.

I understood when the unleaded fuel was introduced that you needed a
Catalytic Converter on the engine to process the emissions correctly which
was why all the new cars then were so equipped with the cat.  Now I hear
everybody saying that you can run unleaded in leaded engines without
problems.  I know that other countries are doing this because there IS no
leaded fuel any more.  What is the story?

There was a little publicity for a while on the benzene or hydrocarbon
emissions that were coming out of leaded engines running unleaded (don't
know what they really were just that they were supposedly worse for the
human race than what came out of ordinary [well tuned] leaded engines).  I
haven't heard any more on this subject for some considerable time now and
presume that the story has been killed off.  I think at the time it was
coming from the classic car camp.

Any opinion?
