Can fully synthetic engine oil be changed every 15,000 kilometers?

[AshleyLynn]

Yes. Fully synthetic engine oil can last up to 15,000 kilometers with a cycle of six months. Here is the relevant information: Engine oil maintenance cycle: The engine oil maintenance cycle refers to how often the engine oil should be changed in a car, and this cycle depends on the type of oil. The maintenance cycle for conventional oil is 5,000 kilometers, for semi-synthetic oil it is 7,500 kilometers, and for fully synthetic oil it is 10,000 kilometers. Precautions: In fact, the engine oil maintenance cycle is closely related to personal driving habits and driving conditions. If you frequently encounter traffic congestion in the city or drive in extremely hot or cold regions, the oil should be changed earlier. If the vehicle often drives on highways with little traffic congestion, the oil change can be delayed. For new cars, it is essential to strictly follow the time and mileage specified in the user manual for oil changes.
