Nissan air conditioning systems use several different compressor oils depending on compressor design and vehicle application. One of the most commonly discussed AC compressor lubricants is Nissan Type S PAG oil, which is used in many Nissan and Infiniti air conditioning systems equipped with rotary-style compressors.
Using the correct AC compressor oil is extremely important because the wrong oil viscosity or incompatible refrigerant oil can lead to poor cooling performance, compressor wear, internal contamination, and complete compressor failure. Choosing the proper Nissan Type S PAG oil equivalent helps maintain lubrication, improve cooling efficiency, and extend AC system life.
What Is Nissan Type S PAG Oil?
Nissan Type S PAG oil is a specialized air conditioning compressor lubricant used in various Nissan and Infiniti AC systems. It is designed to lubricate internal AC compressor components while remaining compatible with R134a refrigerant systems.
In many applications, Nissan Type S oil is commonly equivalent to PAG 46 oil, especially for rotary-style AC compressors used in Nissan vehicles.
Best Equivalent: Most Nissan Type S compressor oil applications use PAG 46 refrigerant oil or OEM-equivalent AC compressor oil.

How to Add PAG Oil to a Nissan AC Compressor
Common Nissan AC Compressor Problems
Compressor Failure
Using incorrect PAG oil viscosity may cause internal compressor wear and premature compressor failure.
Poor AC Cooling
Incorrect oil amounts or contaminated refrigerant can reduce AC cooling performance significantly.
Compressor Noise
Low oil levels or insufficient lubrication may produce grinding or whining compressor noises.
Internal Contamination
Failed compressors can spread metal particles throughout the AC system and damage additional components.
Signs Your Nissan AC System Needs PAG Oil Service
- Weak AC cooling performance
- Compressor whining or grinding noise
- Warm air from vents
- Compressor clutch cycling rapidly
- Visible AC system leaks
- Compressor seizure
- Metal contamination in refrigerant
- AC system overheating
Maintenance Tips for Nissan AC Systems
- Use only approved PAG oil viscosity
- Replace the receiver dryer during compressor replacement
- Vacuum the AC system properly before recharge
- Never overfill compressor oil
- Check for refrigerant leaks regularly
- Use OEM-quality AC components
- Operate the AC system regularly
- Keep condenser fins clean
