What year engines need zinc?

Zinc acts as a friction inhibitor, and research suggests that older engines using “flat tappet” lifters in the engine (pretty much any V6 or V8 older than 1988) need to have zinc present in the engine oil in order to keep the camshaft and lifters from wearing prematurely.

How much zinc does an old engine need?
