How many kilometers does a car's engine oil generally need to be changed?

[SanTimothy]

It might be time to change it at 5,000 kilometers. Replacement cycle: It largely depends on the quality of the engine oil and the external driving environment. For example, if the vehicle uses mineral oil and the external driving environment and temperature are not too low, the engine oil can be changed at 5,000 kilometers or within 6 months. Introduction: If the vehicle uses semi-synthetic oil (which is commonly used in the first and subsequent maintenance services for modern vehicles), and the external driving environment is not too harsh, the engine oil can generally be changed within 7,500 kilometers or 6 months without any issues. If the vehicle uses fully synthetic oil and hasn't been driven for a very long distance, the engine oil can be changed at 10,000 kilometers or within 12 months, which is completely feasible.
