The replacement cycle and importance of automotive oil filters

The replacement cycle of a car's oil filter is closely related to the type of engine oil used. Generally speaking, if mineral oil is used, the oil filter should be replaced every 3,000 to 4,000 kilometers or within half a year. If semi-synthetic engine oil is used, the replacement cycle is 5,000 to 6,000 kilometers or half a year. If fully synthetic engine oil is used, the replacement cycle can be extended to 8 months or 8,000 to 10,000 kilometers.

The importance of the oil filter is mainly reflected in the following aspects:

Protecting the engine: The oil filter can effectively prevent impurities from entering the engine, reduce engine wear, and thus extend the engine's service life.

Improving fuel efficiency: The oil filter can keep the engine oil clean, reduce the friction inside the engine, and improve fuel efficiency.

Maintaining the performance of lubricating oil: The oil filter can prevent impurities from affecting the performance of lubricating oil and keep it in good condition.

Reducing environmental pollution: The oil filter can reduce the emission of pollutants caused by engine wear, playing a certain role in environmental protection.

Therefore, regularly replacing the oil filter is crucial for maintaining the normal operation of the car engine and extending its service life. When changing the engine oil, the oil filter is usually also replaced at the same time to ensure the cleanliness and filtering effect of the oil.
