Actually, they do show the amounts separately for 10w40 and 20w50. Second

Phosphorus, wt % 0.077 0.108
Zinc, wt % 0.085 0.119
Too bad we aren't chemists. Let's see, we need the atomic weight for zinc
and phosphorus, the actual formula for the ZDDP molecule, and the weight of
a quart of Kendall GT-1 20w50...
