What engine oil should be used for China VI compliant vehicles?

[DiLondon]

China VI compliant vehicles should use 5w30 engine oil. The introduction of 5w30 oil and the classification standards for engine oil are as follows: Introduction to 5w30 oil: 5w30 oil can withstand an external low temperature of -30 degrees Celsius, and its kinematic viscosity standard at 100 degrees Celsius is 30. Classification standards for engine oil: The 'W' stands for Winter, and the smaller the number before W, the better the low-temperature fluidity of the oil, indicating a lower usable environmental temperature and better protection for the engine during cold starts. The number after 'W' represents the viscosity index of the oil at high temperatures. The larger the number, the higher the viscosity, which provides better protection for the engine but also consumes more fuel.
