Refrigerant Oil: Service and Repair

DURING A/C COMPRESSOR REPLACEMENT
A new FS-10 replacement A/C compressor contains no refrigerant oil. If the amount of oil drained from the removed A/C compressor is between 85 ml to 142 ml (3 oz to 5 oz), pour the same amount, plus 1 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.
