The FJC 2491 PAG Oil is a high-quality synthetic Polyalkylene Glycol (PAG) lubricant specifically formulated for use in automotive air conditioning systems. This product is designed to meet OE (Original Equipment) viscosity standards and is recommended by both OE and compressor manufacturers for optimal performance and system longevity.
It is a PAG 150 viscosity oil, suitable for R134a refrigerant systems. The oil contains synthetic refrigerant oil (Polyalkylene Glycol) along with essential additives to ensure proper lubrication and corrosion prevention within the A/C system.

2. ข้อมูลด้านความปลอดภัยที่สำคัญ
- Always wear appropriate personal protective equipment (PPE), including safety glasses and gloves, when handling refrigerants and oils.
- Ensure proper ventilation when working on automotive A/C systems.
- PAG oil is hygroscopic, meaning it absorbs moisture from the air. Keep the container sealed tightly when not in use to prevent moisture contamination.
- Dispose of used oil and refrigerants according to local environmental regulations. Do not pour into drains or dispose of with household waste.

3. การตั้งค่าและการเตรียมการ
Before adding FJC 2491 PAG Oil to an automotive A/C system, ensure the system is properly prepared. This typically involves evacuating the system to remove all existing refrigerant and moisture. Consult your vehicle's service manual or a qualified automotive technician for specific procedures related to your vehicle's A/C system.
3.1 Tools and Materials Required:
- Vacuum pump and manifold gauge set for A/C system evacuation.
- Appropriate A/C system service ports and adapters.
- Safety glasses and chemical-resistant gloves.
- FJC 2491 PAG Oil.
3.2 System Evacuation:
It is crucial to evacuate the A/C system thoroughly before adding new oil or refrigerant. This process removes air and moisture, which can cause system damage and reduce cooling efficiency. Follow standard automotive A/C service procedures for evacuation.
4. Operating Instructions (Adding Oil)
The FJC 2491 PAG Oil is designed to be added to the A/C compressor or directly into the A/C system during service or repair. The exact amount of oil required will vary depending on the vehicle manufacturer's specifications and the extent of the A/C system repair (e.g., compressor replacement, component replacement).
4.1 Adding Oil to a New Compressor:
- Drain any shipping oil from the new compressor.
- Measure the correct amount of FJC 2491 PAG Oil as specified by the vehicle manufacturer or compressor manufacturer.
- Pour the measured oil into the new compressor's suction port or designated oil fill port.
- Install the compressor and proceed with system evacuation and recharging.
4.2 Adding Oil to an Existing System:
- Determine the amount of oil to be added based on the component replaced (e.g., accumulator/drier, condenser, evaporator). Refer to vehicle service data for oil capacity charts.
- Use an appropriate oil injector tool to introduce the FJC 2491 PAG Oil into the low-pressure side of the A/C system after evacuation and before refrigerant charging.
- Ensure the system is under vacuum before injecting oil to draw the oil into the system.
- Once the oil is added, proceed with refrigerant charging according to manufacturer specifications.
บันทึก: Always refer to the vehicle manufacturer's service manual for precise oil capacities and procedures. Using the incorrect type or amount of oil can lead to A/C system damage.
5. การบำรุงรักษา
PAG oil does not typically require routine replacement unless an A/C system component is replaced or a leak occurs. However, regular maintenance of your vehicle's A/C system is crucial for its longevity and efficiency.
5.1 Recommended Practices:
- Have your A/C system inspected annually by a qualified technician.
- Check for refrigerant leaks and address them promptly.
- Replace the accumulator/drier or receiver/drier whenever the A/C system is opened for major repairs, as these components absorb moisture and filter contaminants.
- Ensure the correct type and amount of PAG oil is used if any A/C components are replaced.
6 การแก้ไขปัญหา
Issues related to A/C oil are often symptoms of broader system problems. If you experience A/C performance issues, consider the following:
| อาการ | สาเหตุที่เป็นไปได้ | การกระทำ |
|---|---|---|
| เครื่องปรับอากาศระบายความร้อนไม่ดี | Incorrect oil level (too low or too high), incorrect oil type, moisture in system. | Verify correct oil type and level. Evacuate and recharge system. Consult a professional. |
| เสียงคอมเพรสเซอร์ | Insufficient lubrication due to low oil, incorrect oil viscosity. | Check oil level and type. If noise persists, compressor may be damaged. |
| การรั่วไหลของระบบ | Damaged seals or components, overfilling with oil. | Identify and repair leaks. Ensure proper oil charge. |
For complex A/C system issues, it is highly recommended to seek assistance from a certified automotive A/C technician.
