Not much. To distribute ZDDP in synthetic oils, most compounders use specialized mixing processes that involve the addition of additives specifically to get it mixed in and keep it uniformly distributed in the final mix. One of the reasons synthetic oils have limited shelf life is because these ZDDP distribution additives fail over time and the oil begins to striate. So simply pouring in some expensive ZDDP into your oil is not going to get it uniformly distributed or likely to keep it there.
