Oil zddp ?

Where do you think the 8 oz. ZDDP could go, that 256 oz. of oil poured in the same opening won't get to it and carry it to the pan?
It takes about 10 seconds it takes to pour it in the oil, or about 10 seconds to pour it in the valve cover. Only 10 seconds it takes to shake it up, I think I'll go ahead and pour it in the oil, ya know, pre-mix? 10 extra seconds... C'mon, man!
