The lead (actually tetraethyllead) in fuel didn't get replaced, just not
added anymore.
Well, partly, as lead was used for two purposes, as valve wear protection
and as antiknock agent.
For the latter purpose alternative additives are used (but I don't think it
is "benzene", whatever that may be in English)

See http://en.wikipedia.org/wiki/Tetraethyllead for details.

Whether there is an NG for discussing this I have no idea.

chemistry or physics I suppose. Try googling tetraethyllead.

the english for "benzene" is "benzene" and it doesn';t sound a good
ant-knock agent. I understand they reduced the amount of branching in
the carbon chains.

Ah. I googled apparently "aromatic" ("has carbon rings") compounds are
used though benzene isn't mentioned.

http://en.wikipedia.org/wiki/Antiknock_agent

then search for a chemistry or environment forum.

Ah, Benzol in German.
