lead additive, setting time



I was actually thinking about this when i read the
post by the fellow who paid $90 for a tank of 100
octane fuel.  I've owned 2 1967's, and neither one of
them had a problem drinking 93 (or 92, when I drove
into Pennsylvania).  Its all a matter of timing.  For
both of my '67's, I drove them for a while with a
distributor clamp wrench in the door compartment, and
if I heard them ping, I would retard the timing a bit.
 Of course, this requires an initial setting that's a
bit advanced, and a little guess and checking.  But
its really the only way to set time on cars of this
vintage.  In fact, I have a '68 volvo who's shop
manual specifically calls this procedure out.  It also
says to drive at about 30-40 mph in top gear up a
moderate hill, accelerate, and listen for pinging
("pinking" they call it...bloody Europeans!)

The only time I run any sort of lead additive is in
this same volvo, and only when I'm rallying
it...Unless anyone here drives their Imperial that
hard, I wouldn't worry about adding anything to the
fuel.
