When you replaced the compressor did you flush the complete system?
Okay on a system with rear AC you will need 11 ounces of oil for the complete system and yes you will need t place 2 of them in the new compressor and the rest of the oil through the system. See the link below for where the new oil need to go after the flush.https://dl.dropboxusercontent.com/u/104923897/Oil%20May%2015.pdf
Yes , the old oil will come out when you do the flush.
You can use any brand of Pag oil .
GM calls for GM P/N 12378526 which is Pag 46 synthetic oil.
