Can't find the thread now, but I recall someone posting the structure of a typical ZDDP molecule and I think the zinc was something like 10-20% of the total molecular weight. So 30,000 ppm ZDDP would show maybe 5,000 ppm Zn in a VOA.

I think you are pretty close.
Paul the juice has 12-15% ZDDP compound.

Good deal on the "juice" and good deal on the Pro-formula. Hmmmm SLOB must be close to 5% zinc compound with its 4900 ppm zinc.
