Aha! So the newer engines can tolerate lower ZDDP levels because of the
different materials used. That makes sense. I believe most overhead cam
engines have flat tappets, just as older v-type engines. But there still has to
be a huge number of pre-2000 V-type engines out there that don't know they
should be wiping off cam lobes.

when all this started it was said that the manufacturers were making cams and
lifters from hardened steel rather than iron. that did the fix for new
production.
