The limited documentation on the compressor said to leave it in the compressor. I think it shipped with pag150 and ice32, so it would probably be safe to leave it. I need to look at the warrantee to be sure, if i need to leave that oil, it makes sense to drain and measure it, add the correct amount back to the compressor, then add the correct amount if fresh pag150 to the drier, evap and condensor.

I thought the fsm wanted you to drain the new compressor and add fresh oil, but i may have been mistaken.

I want to try to retain the warrantee on the conpressor if at all possible.
