The use of PAG oil is essential in this context because it remains stable within the sealed system loop, ensuring that the refrigerant charge remains intact for the lifespan of the vehicle, thus preventing unnecessary venting into the atmosphere. Unlike traditional mineral oils, PAG oil actively absorbs water from the atmosphere, which can lead to acid formation and subsequent corrosion within the sealed system.
