How often should the engine oil be changed for a Haojue scooter motorcycle?

[LeBriella]

Generally, the break-in period is 2000 kilometers, and it's even better if it reaches 3000 kilometers. For a new motorcycle, the first oil change is best done at 300 kilometers because during the break-in period, there will be a lot of metal shavings mixed in the oil. If the oil filter screen doesn't filter properly, these shavings can be pumped along with the oil to various friction surfaces, accelerating wear on those surfaces. Here are some details about motorcycle engine oil: Precautions for changing motorcycle engine oil: When changing the engine oil for a motorcycle, it's important to note that during the break-in period, using more expensive oil isn't necessarily better. At this stage, it's recommended to use ordinary mineral oil because fully synthetic oil reduces friction between mechanical parts. The purpose of the break-in period is to allow the new parts inside the engine to properly wear in. Auxiliary cooling: Due to its lower specific heat value and being inside the engine, engine oil itself does not have a cooling effect. However, during engine operation, the heat generated by fuel combustion can be carried back to the oil tank by the engine oil and then dissipated into the air, helping the radiator cool the engine. The real cooling effect comes from the water outside the engine casing.
