Click the "Search" button right above your posting and search on ZDDP
A lot of people posted a lot of disagreement about 18 months ago when an article was published on ZDDP and mechanical-lifter/cam break-in problems. Now, that lack-of-ZDDP-problem from oil used with new cams/solid-lifters is a fairly well-accepted reality.
