A/C COMPRESSOR OIL - NISSAN
APPLIED MODELS: ALL MODELS
SERVICE INFORMATION:
The recommended refrigerant oil for all Nissan A/C systems is SUNISO 5GS. SUNISO 5GS is now available from SUNISO distributors in one quart
containers. When ordering the oil, specify part number L315, which is the number for a single, one quart container.
Dealers are encouraged to use one quart containers to prevent oil contamination. When left open to the atmosphere, compressor oil will absorb moisture
that renders it unfit for use. To avoid this, order one quart containers, open only one at a time, and keep them tightly sealed when not in use.
Due to the higher operating temperatures of our latest generation of A/C compressors, a 5GS oil is required to ensure optimum compressor performance.
The use of lighter viscosity oil commonly found at auto parts supply stores can cause premature compressor failure.
