Personally, I would never try to ad ZDDP to the crankcase.  Too easy to get 
the proportions wrong (too much ZDDP is not a good thing, either), and you 
are introducing a large "blob" of the stuff into one place, and depending on 
the engine's oil circulation system to blend it evenly throughout the entire 
system.  I somehow don't think that is going to happen, and can envision 
pockets of ZDDP lying here and there in random locations throughout the 
system.  Sure, you could pour the oil into a big container, then ad the ZDDP 
& stir it up before putting the oil into he engine.....but why go to all the 
bother when some of the more reputable refiners have already done it for 
you?
As far as knowing that you are getting SJ spec, as opposed to 
SM..........well, there is where the brand name may be relevant.  If Brad 
Penn, Valvoline, Castrol or Shell says it's SJ spec, well, I think I would 
feel quite safe with it.
