How Many Kilometers Should You Drive Before Changing the Engine Oil?

[MacJulia]

Generally, the engine oil should be changed every 5,000 kilometers. However, the actual interval for changing the engine oil depends on various factors, including the quality of the oil used, the driving environment in the region, and the age of the vehicle model. Engine oil, also known as motor oil or engine lubricant, is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers. In addition to determining the oil change interval based on mileage, engine oil also has a shelf life. Compared to being stored in an oil container, the shelf life of oil in the harsh high-temperature and high-pressure environment of an engine is significantly shortened, and its performance greatly deteriorates. Over time, it fails to protect the engine effectively. Therefore, even if the vehicle has driven fewer kilometers, it is necessary to change the engine oil regularly.
