I do have a brand new/unused set of Robinair gauges. The culprit is an 87 Aries wagon system w/A590 compressor. I am replacing A590 compressor with reman. unit and the changing out the drier. I want to use Polyalpha oil. Isn't this oil compatible with either R134a or HC refridgerants? I'm leaning toward HC"s. Any suggestions? Thanks for your reply. -PTT
