My understanding is that, yes, you CAN have too much ZDDP. At higher
levels, zinc and/or the phosphorous in ZDDP can microscopically etch
metal surfaces. I believe ZDDP was initially used for its detergent
properties, before its protective properties were noticed (but can't
prove it). A pretty graph here, and you can always search on 'can there
be too much ZDDP:'
