The system holds 9 ozs of PAG 150 oil and 24 ozs of R134a. When I replaced my compressor, I fill it with about 4ozs. This isnt easy, you have to put a little bit in the suction port and spin the compressor until it sucks the oil it....continue until fresh oil spits out. Then I put another 4 ozs in the new accumulator. Bolted everything up, evacuated, and refilled.
