The working principle of the automobile oil drain screw is a screw located at the bottom of the engine oil pan through its special structural design. When the engine maintenance needs to change the oil, the old oil can be discharged by unscrewing the screw, and then the screw can be added to the new oil from the filling port above the engine
The main function of the oil release screw is to prevent oil leakage, ensure the tightness of the oil, so as to ensure the lubrication effect of the engine
Protect the engine : oil screw can effectively remove metal particles and impurities in the old oil, reduce engine wear, protect the engine performance
reduces maintenance costs : The traditional method needs to remove the oil release screw every time the oil is changed, which is not only complicated, but also easy to cause screw damage and oil leakage. The design of oil drain screws reduces this need and saves the cost of replacing screws and oil pan
high efficiency and environmental protection : compared with the traditional way, it takes a long time to wait for the oil to cool and flow out naturally, which improves the efficiency and conforms to the modern high efficiency and environmental protection maintenance concept
