A good review of a very specific topic, relevant to "classic and performance engines with flat tappet cam/follower designs", as it relates to anti wear, less relevant to roller follower designs(which we have).

ZDDP is also a very cost effective anti oxidant as well as an anti wear additive. More is not always better, and it is the job of the formulators to get the compositional balance appropriate to meeting the performance(sometimes conflicting)requirements set out for a given product and application. Often the composition differences only reflect the fact that there may be more than one way to deliver performance. Performance should be of primary importance in lubricant selection.
