Handling Compressor Oil
WARNING: This page is about a different car, the 2020 Mazda MX-5 Miata. However, it is still accessible from the selected car via links, so may be relevant.
- Always use the following specified compressor oil (PAG oil) for the vehicle. If compressor oil other than the specified type is used, the refrigerant performance may be lowered or the refrigerant system parts may be damaged.
| Refrigerant type | Specified compressor oil |
| HFC-134a (R-134a) | DH-PR |
| HFO-1234yf (R-1234yf) | YR20 |
- Do not spill compressor oil on the vehicle. A drop of compressor oil on the vehicle surface can eat away at the paint. If compressor oil gets on the vehicle, wipe it off immediately.
- Compressor oil (PAG oil) has a higher moisture absorption efficiency than the previously used mineral oil. If moisture mixes with the compressor oil, the refrigerant system could be damaged. Therefore, install caps immediately after using the compressor oil or removing refrigerant system parts to prevent moisture absorption.
- If the refrigerant gas is completely discharged from the system for reasons such as a malfunction during A/C operation, repair or replace the malfunctioning part, charge the refrigerant to the specified amount and always add 60 ml {60 cc, 2.0 US fl oz} of compressor oil. If the compressor oil is not adequately replenished, the A/C compressor may quickly deteriorate, abnormal noise may develop, cooling performance may be affected or, in the worst case, the A/C compressor may seize.
