How to judge whether the oil filter needs to ｒｅｐｌａｃｅ the filter element

The methods for judging whether the oil filter needs to be replaced mainly include the following points:

‌Core answer: It can be comprehensively evaluated by checking the oil status, the appearance of the oil filter, the driving experience, and the reference replacement cycle.

‌Check the oil status‌:

Observe the color and texture of the oil. If the oil becomes very black, or there are obvious impurities and sediments, this may be a signal that the filter is not filtering well and the filter needs to be replaced.

Use oil test paper to detect the quality of the oil. Dip the test paper into the oil and compare it with the color card. If the test paper shows that the oil color is black or contains impurities, it indicates that the filtering function of the oil filter may be damaged.

‌Check the appearance of the oil filter‌:

Observe whether there is obvious damage, deformation or dirt on the outside of the oil filter. If a large amount of impurities, sludge or severe wear is attached to the surface of the filter, it means that the filter has lost its filtering effect and needs to be replaced.

‌Evaluate the driving experience‌:

If the vehicle seems weak when accelerating, the engine noise increases, or the fuel consumption increases abnormally, these may be signs of a clogged oil filter and should be checked and replaced in time‌.

‌Reference replacement cycle‌:

Determine the replacement cycle of the oil and oil filter according to the type of oil used (such as mineral oil, semi-synthetic oil or fully synthetic oil) and the recommendations of the vehicle manufacturer. Usually, the replacement cycle of the oil filter is the same as the replacement cycle of the engine oil‌.

‌Other detection methods‌:

Smell the oil. If the oil has a strong sour smell, it may indicate that the oil has deteriorated and the filter needs to be replaced‌.

Use professional detection tools to perform pressure tests or flow tests to test the performance of the oil filter‌.

Through the above methods, it is possible to comprehensively evaluate whether the oil filter needs to be replaced to ensure the normal operation of the equipment and the cleanliness of the oil.
