Okay I'm working on my 05s ac system replacing compressor expansion valve drier and condenser need help with oil quantity. New compressor came with 5.3 oz. service manual says comp 4.7 evap 2.0 condenser 0.5 suction line0.3 receiver 0.3 which all adds up to 7.8? But then it says the formula is new compressor 4.7oz - old compressor oz = how much oil gets distributed into everything else?
