Can universal pag oil be used in any r134a system?

I would not recommend it. You should be using the pag oil that is referenced by your compressor’s manufacturer. These manufacturers test varying types of oil and choose the one that best protects their individual design.

Each compressor and or manufacturer may recommend a different variant of pag oil and by following their instructions you will prolong the life of your compressor and your air conditioning system.
