Refrigerant Oil: Service and Repair

DURING A/C COMPRESSOR REPLACEMENT

1. A new FS-1O service replacement A/C compressor contains refrigerant oil and must be drained into a clean container before any oil is added. If the amount of oil drained from the removed A/C compressor is between 85 and 142 ml (3 oz. to 5 oz.), pour the same amount plus 1 (one) ounce of clean oil into the new A/C compressor. If the amount of oil drained from the old A/C compressor is greater than 142 ml (5 oz.), pour only 142 ml (5 oz.) of clean refrigerant oil into the new A/C compressor. If the amount of refrigerant oil drained from the old A/C compressor is less than 85 ml (3 oz.), pour 85 ml (3 oz.) of clean refrigerant oil into the new compressor.
^ When replacing components of the air-conditioning refrigerant system, add oil to the replacement components.
