Can You Change the Oil Without Replacing the Oil Filter?

[LiamRose]

You can choose not to replace the oil filter when changing the oil, but it is generally recommended to replace both the oil and the oil filter simultaneously. The replacement intervals for oil and oil filters are as follows. Oil Replacement Interval: Conventional mineral oil can typically be replaced at 5,000 kilometers, while semi-synthetic oil can be extended to 7,000-8,000 kilometers. Full synthetic oil, being of the highest quality, can be replaced at around 10,000 kilometers. When selecting oil, it is not always necessary to choose full synthetic oil; more emphasis should be placed on the vehicle's manual and professional advice. Oil Filter Replacement Interval: The oil filter is usually replaced at the same time as the oil. Under normal circumstances, lower-quality oil contains more impurities, which increases the pressure on the oil filter during the filtration process, thereby affecting its functionality. Higher-quality oil, with fewer impurities, can extend the lifespan of the oil filter to varying degrees.
