Yes, unfortunately the marketers are very good at their craft and can get a
lot of people to buy their snake oil. Unless you were running your engines
at very high power/rpm you didn't need to add lead. It didn't hurt, but you
didn't need it. And now they are selling oil additives that haven't been
tested - which means you are the test case. I have less concern over oil
formulated with high ZDDP but you still do not need it. Remember, your
engine was designed when oil had about the same levels as today.
My personal belief for the failures was that when parts started being made
offshore - US or UK - in India and Sri Lanka they were bad. While many of
the workmen are quite skilled, the metallurgy in the area was and still is
very substandard. This exists even today, look at the problems Royal Enfield
is having, although to their credit they are improving.

Folks,
I am with Barney! So I will go to Canadian Tire and to get a a Teflon
coating and buy asbestos underwear (with double acting, non slip flaps) I
have told this story several times already but here it goes
again............
Shell used my restored Austin Healey BJ8 with rebuilt engine to test wear
using their lead free fuel. They made a special measuring device and took
enormous care to measure the wear due to my driving (reasonably hard but not
auto-cross ertc) the car for a
year. Result - no measurable wear !
