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

[Rex]

Newly purchased scooters generally require the first oil change at 350 kilometers. The second oil change should be done between 800 to 1,000 kilometers, and the third at 1,500 kilometers. After that, the oil should be changed every 2,000 to 3,000 kilometers. Functions of engine oil: Engine oil not only lubricates the engine but also cleans, seals, cushions, prevents rust, and dissipates heat. If the oil is not changed for a long time, it will accelerate engine wear. Methods to determine if the oil needs changing: Smell test: Pull out the dipstick and smell it closely. If there is a strong sour odor, the oil has deteriorated and should be changed. Finger rub test: Rub the old oil between your thumb and forefinger repeatedly. If you feel impurities, poor viscosity, or even a gritty sensation, it should be changed. Color test: Place a few drops of old oil on a clean white filter paper. After the oil has seeped in, good-quality oil will leave no powder, feel dry and smooth to the touch, and have a clear yellow infiltration zone. If the oil appears dark brown or has impurities, it should be changed.
