Would that not be overkill? If you use a diesel oil that in theory already has sufficient additive for a flat tappet, and then add the external additive wouldn't that result in too much zinc?

When I was looking into this I seem to remember reading that an overabundance of zinc anti wear additive can backfire and actually create wear.

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
