Sealant or/and Oil

WARNING: This page is about a different car, the 2009 Nissan Maxima. However, it is still accessible from the selected car via links, so may be relevant.

Never mix HFC-134a refrigerant and oil with CFC-12 (R-12) refrigerant and oil.
Separate and non-interchangeable service equipment must be used for handling each type of refrigerant and oil.
Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles refrigerant and oil) are different between CFC-12 (R-12) and HFC-134a (R-134a). This is to avoid mixed use of the refrigerant and oil.
Never use adapters that convert one size fitting to another, as refrigerant and oil contamination will occur and compressor failure will result.
