Which PAG oil for A/C to use

[Firstcorvette]

Hi everyone I am adding oil to my 02 C5 a/c system and im getting conflicting info on the weight of the oil, some places tell me its PAG 46 and another says PAG1 50, I cant find any definitive answers. The local dealer has a GM part number for 8 ounces of it and its $56 no thanks. Can anyone confirm?

Found this , I hope it's a help. Yes , using AI .
For a 2002 C5 Corvette A/C system, the usual compressor oil specification is PAG 150, and a compressor replacement typically takes about 2 ounces of oil in the new compressor, with the total system amount commonly around 6 to 10 ounces depending on what parts were replaced and how much oil was lost .
Practical rule
Compressor only: add about 2 oz of PAG 150 to the new compressor .
If other components were replaced: the total oil charge should be adjusted based on the oil removed/drained from the old parts, not just blindly topped off .
Important note
The exact amount can vary with the repair, so if you’re servicing only one component, it’s best to match the oil quantity to what was lost or drained rather than overfill the system.
