ZDDP is a discrete chemical compound and I'm sure neither product is 100% ZDDP so a logical guess would be the difference may be the amount of ZDDP that's formulated into whatever the rest of the product is. What do the labels say? High amounts of ZDDP are proven to be harmful so don't go overboard.
