There are different refrigerant oils depending on the manufacturer. Refer to the Parts Information for the part number.
Refrigerant oil strongly attracts moisture. Because of this, refrigerant oil that was stored for long periods of time in an open container is unusable.
-- Close opened containers immediately after use to prevent moisture contamination.
