As a driver needs to have mechanical knowledge, it is necessary to change the oil and oil filter of the car regularly. A quality oil filter must be replaced every time the oil is changed.
After the
oil filter is used for a long time, its filtering efficiency will decrease, and the oil pressure passing through the filter will be greatly reduced. Although the oil pressure is reduced to a certain level, the filter bypass valve will open, and the oil will enter the oil circuit through the bypass to prevent insufficient oil pressure. However, the oil entering the oil circuit at this time is not filtered and will carry impurities into the oil circuit. Increase the wear and tear of parts, and in severe cases, impurities in the oil will even block the oil passages and cause mechanical failures. Therefore, the quality of the oil filter directly affects the effect of oil on engine lubrication.
