The instruction sheet that was with the compressor said it was SHIPPING LUBE as I stated. And NO mention of how much oil in the way of number of fl. oz was already installed. And said DON'T DRAIN the shipping oil from unit. The shop manual will tell me how much oil to put in a dry unit. The instruction sheet also stated to check the maintenance manual for the proper number of fl. oz required. My real question is. What have others done. The oil level is vary important. Plus the instruction sheet has no phone # to contact. Bob Dunahugh

I have never known anyone to replace an A6 compressor with a new / commercially rebuilt one. So my suggestion is to call whomever you bought it from and ask what type of oil is in it. Whatever you do, do not mix oil types.
If you are worried about too much or too little oil, there is a procedure on how to check the oil level after installation. Again, it is written up in the AC section of the manual that I referred you to in my previous posting.

I recently rebuilt the A/C system in a 73 Gmc. The Compressor was noisy so
I replaced it with a Factory Rebuilt one from Jim K. The hoses were
deteriorated, and leaked, as did the condensor from external damage. So I
replaced the receiver/dryer as well. I flushed the evaparator so the system
was completely empty. After pulling a full vacuum, I let the system set for
two days under vacuum to leak check it. The instructions that I got with
the Compressor say to fill the Compressor with 6 oz. of oil. Because I used
duracool for a refrigerant, I used synthetic lube like you would use for
134a. When you do not scrub the system or replace the Compressor, they say
to drain the Compressor, measure what you drain out, subtract that volume
from 6oz and add the remainder to the Compressor. What I do.
