Synthetic Oil Improvement in /6

ok, so I know you want a certain percentage of zddp in your oil, and it appears mobile one has around 1000 in it, so how much is the right amount of zddp additive? if I am reading this correctly too much causes wear elsewhere in the engine? just looking for some clarification. and thanks for the info and reading material. lol, but now it's all just as clear as mud, or oil.
