If you have a SFT cam that has been nicely broken in, has gentle ramps, reasonable lift and springs that aren't too heavy then you
might be right. The only way you would know for sure is to swap out your healthy ZDDP
oil for the newer zincless
oil and then waited to see if you ate a lobe or not. Remember, the reason ZDDP was removed from oil is that it damages the catalytic converter. If you don't have a CC on your car there is no reason to avoid ZDDP, which is an absolutely wonderful anti-wear agent.
