Got a Dixie Narco Pepsi mancine that is R-12.
The compressor is bad and I want to replace it and charge it with R-134A.

I want to take a compressor from a used refrigerator from Craigslist or Classifieds and use its compressor. If it uses R-12, I need to drain the Oil from the compressor but what Oil would I use for R-134A?

Would I use PAG or is there a certain kind I have to use for Refrigerators?
