For R-134a car AC systems, the recommended lubricant oil is typically a synthetic Polyalkylene Glycol (PAG) oil. PAG oils come in different viscosities, such as PAG 46, PAG 100, or PAG 150, and the specific type used can depend on the vehicle manufacturer's specifications. It's important to use the correct viscosity to ensure optimal performance and avoid damage to the AC system.
