Will the 4S shop refuse to change the engine oil?

[MadelynLee]

4S shops generally do not have this situation, and many 4S shops already have monitoring functions. The following is the relevant introduction of engine oil: The role of engine oil: That is, engine lubricating oil, known as the "blood" of the car, can lubricate, clean, cool, seal, reduce wear, prevent rust, and prevent corrosion for the engine. Working temperature of engine oil: The engine is the heart of the car. There are many metal surfaces in the engine that rub against each other. These parts move fast and have a poor environment, and the working temperature can reach 400 to 600 degrees. Under such harsh working conditions, only qualified lubricating oil can reduce the wear of engine parts and extend their service life.
