How Many Kilometers Should Car Engine Oil Be Replaced?

[TessaFitz]

Fully synthetic oil should be replaced within 10,000 kilometers, semi-synthetic oil should be replaced every 7,500 kilometers, and mineral oil needs to be replaced within 5,000 kilometers. The following introduces the classification of engine oil and the functions of adding engine oil: Classification of Engine Oil: Engine oil is divided into three categories: mineral oil, semi-synthetic oil, and fully synthetic oil. The replacement cycles for these three types of engine oil are also different. Generally, mineral oil should be replaced every six months or 5,000 kilometers, semi-synthetic oil every six months or 7,500 kilometers, and fully synthetic oil every six months or 10,000 kilometers. Functions of Adding Engine Oil: The quality of engine oil has a significant impact on the working environment of the engine. The engine operates in a high-temperature environment, continuously repeating mechanical friction movements. Engine oil plays a role in cooling, lubricating, and cleaning during this process. Over time, the impurities in the engine oil increase, and its performance declines accordingly.
