How Often Should You Change the Oil for a China IV Motorcycle?

[DelLyla]

For a new motorcycle, change the oil every 1,000 kilometers initially, and then every 3,000 kilometers thereafter. Below is an introduction to the functions of engine oil: The Lubrication Function of Engine Oil: There is rapid relative sliding between the piston and cylinder, as well as between the main shaft and bearing bush. To prevent excessive wear of parts, an oil film needs to be established between the two sliding surfaces. A sufficiently thick oil film separates the surfaces of the relatively sliding parts, thereby reducing wear. The Auxiliary Cooling Function of Engine Oil: Due to its relatively low specific heat capacity and its location inside the engine, engine oil itself does not have a cooling effect. However, during engine operation, the heat energy generated by fuel combustion can be carried back to the oil tank by the engine oil and then dissipated into the air, assisting the radiator in cooling the engine. The actual cooling effect is provided by the water outside the engine casing.
