Is It Okay to Change Engine Oil Without Replacing the Oil Filter?

[StDavid]

You can choose not to replace the oil filter when changing the engine oil, but it is generally recommended to replace both the oil and the oil filter simultaneously. The replacement intervals for engine oil and oil filters are as follows. Engine Oil Replacement Interval: Generally, mineral oil can be replaced every 5,000 kilometers, while semi-synthetic oil can be extended to 7,000 to 8,000 kilometers. Full-synthetic oil, being of the highest quality, can be replaced around 10,000 kilometers. When it comes to choosing engine oil, it is not necessary to always opt for full-synthetic oil; more consideration should be given to the vehicle's manual and professional advice. Oil Filter Replacement Interval: The oil filter is usually replaced at the same time as the engine oil. In general, lower-quality oils contain more impurities, which puts greater pressure on the oil filter during the filtration process, thereby affecting its functionality. Higher-quality oils, with fewer impurities, can extend the lifespan of the oil filter to varying degrees.
