How Many Kilometers Should Truck Engine Oil Be Changed?

[OLilliana]

It depends on factors such as usual driving conditions, personal driving habits, and time intervals. If you frequently encounter traffic jams, drive in sandy areas, or in extremely hot or cold regions, the engine oil should be changed earlier. For conventional oil, it should be changed approximately every 5,000 kilometers. For semi-synthetic oil, change it around 7,500 kilometers. For full-synthetic oil, change it around 10,000 kilometers. Here are some additional details: 1. Vehicles that frequently drive on highways: If the vehicle often drives on highways with little traffic congestion, the oil change interval can be extended. Normally, conventional oil: 5,000 kilometers. Semi-synthetic oil: 7,500-10,000 kilometers. Full-synthetic oil: 10,000-15,000 kilometers. 2. New vehicles: The first and second oil changes must strictly follow the time and mileage specified in the vehicle's user manual. If either the time or mileage is reached, the oil should be changed because the initial oil contains a lot of metal debris, which is very harmful to sealing components, especially for turbocharged models, as it can severely damage the turbo shaft seal. From the third oil change onward, follow the normal mileage interval for oil changes.
