Vehicles manufactured before 1994 typically use CFC-12 refrigerant, which requires a specific mineral oil. Most modern vehicles utilize Polyalkylene Glycol (PAG) oil, which is specifically engineered to work with the latest R-134a and R-1234yf refrigerants.
Car AC Oil Benefits for Air Conditioning and System Lubrication
Unusual noises emanating from the front of the engine. The compressor, the heart of this system, requires lubrication to seal its internal components and prevent metal-on-metal contact.
During a compressor replacement, for example, leaving the old oil in the system mixes with the new oil, diluting its lubricating properties. The compatibility of the oil with the refrigerant is the primary factor.
