Automobile manufacturers have different specifications for refrigerant oil filling quantities. Before refilling, it is essential to measure the residual oil from the old compressor by pouring it into a graduated cylinder. A reference quantity of 100-150 milliliters is typically recorded. The oil temperature should generally be maintained between 45~60℃, with the maximum not exceeding 70℃, and remain stable. If the oil temperature continuously fluctuates and rises slowly, it indicates a malfunction.
