If only the replacement of the new oil without changing the oil filter, then the filter of the 25% pollutants around the old will re-enter the oil circulation, not only increases the chance to wear, but also reduces the performance of the new oil.

As a driver, you need to understand the mechanical knowledge, it is necessary to change the engine oil and oil filter periodically. Each time you replace the oil, you must replace the quality of the oil filter, filter after a long period of use, the filter performance will decline, the oil pressure through the filter will be greatly reduced.

Although the pressure decreased to a certain extent, the oil filter bypass valve will open, will enter through the bypass circuit to prevent the oil shortage, but this time to enter the oil oil unfiltered, will carry the impurities into the oil, increase mechanical wear, serious, impurities even plug oil in the oil, resulting in Mechanical failure

Therefore, the quality of the oil filter directly affects the lubrication of engine oil.
