Try to choose low viscosity oil in winter, but it must be determined according to the local temperature and car grade. The oil of middle and high-grade cars must be selected according to the requirements of manufacturers, and it is not allowed to choose at will.
The viscosity of 5w/40 engine oil at low temperature is lower than that of 15w/40 engine oil, which makes it easier to protect the engine at the moment of cold start. If the viscosity of the selected engine oil is too high, it will make it difficult to start the engine cold. Cold start wear intensifies.
It is recommended that car owners choose original engine oil, because each manufacturer's engine manufacturing process is different, and the engine has different requirements for engine oil. The engine oil specified by the manufacturer was selected after many tests.
