97GLE. I've replaced all three components, on account of a botched AC job last summer that didn't take. The compressor was very loud and was only cooling so-so. Fast forward 1 year, without driving it much at all (new daily driver). I had a shop discharge the system, had about the right amount of refrigerant. Replaced the compressor, condensor under warranty --(don't ask, yay me! ).
On to the question, the total oil capacity is 6.8oz per the FSM, and all other threads that I can find here. The compressor came with 6.8oz PAG46 pre-installed, with the line ports capped with plastic. Since the condensor and the drier each take their own oil, (2 oz and 0.2 oz, respectively), what do I need to do to the compressor? Drain it and fill it with about 4.6oz? Add two oz to the condensor, 0.2oz to the drier, and call it a day? Total oil system= 6.8oz.

Or will the shop incorporate the oil into the system and I leave the compressor with the installed 6.8oz? Just install the condensor and drier minus the oil?

I haven't even thought about adding back the refrigerant yet, I'll let the shop do that, as I've already paid them.

The old compressor is long gone, I don't know how much oil was in it.

Bottom line, how much oil should I add, and where do I add it to equal the total system capacity 6.8oz PAG46 refrigerant oil?
