Oil zddp ?

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!

you mean 10 extra seconds don't ya? :D

Mostly I'm playing devil's advocate here :poke: but if you mix the bottle with one quart of oil, then pour the other seven quarts after it, is that really any better than pouring in the bottle first and adding eight quarts?

:lol:
