So just got my brand used ac compressor and looking to install it my self. On the compressor it calls for "sun pag 56 or equivelnt." I can't find any at all. I only find 46 100 and 150. Anything else would be equal to this?

 

I'm assuming you don't have an A/C machine right? So when you get the system charged by a shop, they will be able to inject the oil, I would talk to them and see what they have. Most compressors come with oil in them, but they will probably need to inject some when charging.

 

usually pag100 will be suffice.
