did more research and I think i got it. Someone could confirm.
30 cubic cm = 1 oz. So I will use the black container above and pour in 1 oz of pag46 into the IN-port on the drier and quickly hook it up and seal the ac system.
10 cubic cm = .33 oz which is needed for any major tubes if I were to flush the old oil out beforehand.
I could also add oil to the condensor and evaporator if I were to flush those out too.
Since I'm reparing the resistors and my ac system was in good working order beforehand, I could just replace the drier and add oil to it. Not flush out the rest of the system out and not add oil to the rest of the system.
And no need to use the above white can of pag46
