Does an oil change require replacing the oil filter?

[CeciliaDella]

Whether the oil filter needs to be replaced is determined by the mileage driven, and it should be replaced approximately every 5,000 kilometers. However, if the mileage hasn't reached 5,000 kilometers, the oil filter should still be replaced whenever the oil is changed. Below is extended information about the standards an oil filter should meet: 1. Filtration capability: It should have high filtration efficiency to effectively remove impurities from the oil. 2. Mechanical strength: It should possess sufficient mechanical strength to withstand certain pressure differentials. 3. Cost-effectiveness: It should be easy to clean, resistant to corrosion and aging, and affordable. 4. Filtration accuracy: The filtration accuracy of the oil filter must ensure that the filtered particle diameter is smaller than the clearance of moving parts and the thickness of the oil film. Different equipment characteristics require filters with varying filtration accuracies, which is crucial for the proper operation of the lubrication system.
