Looking for some guidance. Noticed I have a bit of a leak by the two AC lines going to top of compressor.  Looks like just the O-Rings on those lines gave out. AC still works at this time. 2013 GTS.

I read through the repair manual and am getting hung up on the replacement of compressor oil. Does that oil evacuate with the refrigerant?  Meaning, let’s use an extreme example of a large leak where all pressure is lost in the system. Would all the oil also be missing and need to be added?  Or will you only lose oil by removing/replacing a component like the compressor?
