97 grand prix A/C compressor oil ?

[Drfloppy]

Hello, I have a 97 grand prix gt that has a bad ac compressor. I purchased a new compressor for the car, but on the box it says must add oil. so what I need to know is what is the oil and how much does it need.. The guy that I am going to have charge it for me does refrigeration for dairy farms and what not. He does have a oil, but I wanted to make sure it is the same stuff, and I have no idea how much to put in it.. so I figured no better place to come than here, because you guys always help me out. thank you so much !!

It is called PAG Oil #12345923 (old part number). The system needs 8 oz after a full evacuation. I am quite sure you can use the stuff available at the auto parts stores as long as it is for R134a systems.
