AC system oil capacity

I’m replacing my compressor and I need to estimate how much oil to leave in the new compressor.   

Does anyone have the whole system oil capacity?!?

Dug through the entirety of the manual. All references to AC oil besides lubricating O rings here: 

Installing condensor: If condensor was replaced, Add: 40 cc (1.4 fl.oz.) Compressor oil: ND–OIL 8 or equivalent to compressor

Installing cooling unit: If evaporator was replaced, Add: 40 cc (1.4 fl.oz.) Compressor oil: ND–OIL 8 or equivalent to compressor

Thanks for hunting up the numbers!   That gibes with a sheet I found that also shows 1.4 oz for condenser or evap replacement.  

 

It also shows 4.1 oz for compressor replacement.   With your numbers I think I’ll trust the random sheet I found.

This info is coming in quite handy.  I'm in the process of charging my AC system with Freon now (or soon I guess), and the new compressor came with oil already filled, but I'm not sure if I need to add oil for the other components.  I did not change them, but I did change out the filter in the condenser.  So maybe I need to add 1.4oz of PAG oil?  I don't want to add too much, but I don't want there to be too little either.
