<VV> gasoline - now no lead

My 62 bought in 66 had 44K miles on it and burnt exhaust valves. Got it
for $400, pulled the heads and did a valve job and all was well. GM had
installed some poor valves, the seats have always been good, however.

That was back in the days of tetraethyllead, long gone, thankfully!

The problem with using a TEL concentrate is a little does a lot for
octane, but a lot more doesn't get you much further up the octane
curve.

But hey, at least there's the lead fouling!

=============================
My badly tuned (by me) turbo started to misfire after relatively few
miles on Sunoco 260 back then.
New plugs would fix it, but not as well as a the Delta Mark 10 CDI.


Amoco sold lead free (super) premium practically from the beginning.

At the time there were some rumors that it caused valve burning.
With the known possibility of valve recession in old engines these
days it seems like there might have been some truth to it.
