[94 Daily Driven 4.6L]

In regards to compressor oil. I'm going to have to replace the compressor in my Aspire and I've run into a snag on which oil to use.

Per the OEM Manual:

"Motorcraft Refrigerant Oil YN-12b or equivalent meeting Ford specification WSH-MIC231-b" and specifically states "Do not use Motorcraft YN9 or YN12 oil".

If I look up YN-12b it is PAG 46

Per the tag on the new compressor:
Use Synthetic oil #12345923" Which if I look 12345923 up correctly is PAG 150

The compressor is a reman'd Matsu****a SA1150AE4 Compressor.

So who wins, the OEM manufacturer or the tag on the compressor? Or does it matter since I'm only adding a small amount?

I'm no guru but I'd go with the tag on the reman just because I don't know if it was reman'd to Ford spec EXACTLY or not...
