Why is there no oil change of a circulating engine in foreign countries? Does Mercedes-Benz allow a circulating engine to change oil?

There are two methods for changing gearbox oil, namely gravity change method and cycle oil change method. However, some friends are curious about why there is no oil change of circulating machines in foreign countries, and what are the shortcomings of circulating machines.

There is no oil change for circulating engines in foreign countries because the kilometers of many foreign cars are relatively high compared to domestic ones. At this time, there will be certain risks. Although the cycle machine can indeed increase the rate of oil change, and it can also completely replace the oil and remove impurities, but some impurities will directly block the torque converter, hydraulic valve body, and gearbox filter along with the flow of the pipeline. Nets and other components, resulting in abnormal phenomena such as poor oil flow and stuck solenoid valves.

BenzIs it not allowed to change the oil of the circulating machine?

Mercedes-Benz does not use the cycle engine to change the oil sequentially, because the Mercedes-Benz models are replaced with ATF oil, and the cycle machine cannot control the circulation pressure of the oil well. At this time, it will easily affect the performance of each seal. In severe cases, the valve body and hydraulic control unit will be damaged.Yuan, The maintenance cost at that time is quite high, so be sure to pay attention to it during maintenance.
