As one of the three filters, the oil filter is an important part of the vehicle and is a consumable. Many friends do not know the function of the oil filter and its replacement cycle. In fact, as a filter device, the oil filter basically needs to be replaced at the same time every time the oil is replaced. Of course, if it is aperiodic Normal oil changes will depend on the situation.
The changed machine filter
Some readers asked, do you need to change the oil filter every time you change the oil? The filter can purify the oil. How much does it matter? We consulted experts on lubricating oil usage. Experts emphasize: the oil filter must be changed when the oil is changed.
Every oil change must be replaced with a full-flow oil filter??a paper filter element. The filtration efficiency of the paper filter element will decrease after a long time of use, and the pressure of the oil passing through the filter will be greatly reduced. Although the oil pressure drops 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, but the oil entering the oil circuit is not filtered at this time, which will cause pollutants to enter the oil circuit , increase the wear of the parts.
Therefore, the filter plays a vital role in purifying the oil. The impurities and pollution particles in the oil will be filtered out by the filter. In this way, the oil entering the oil circuit is very clean, which can effectively prevent the abrasive wear of the engine parts caused by the particulate matter.
If only the new oil is replaced without changing the oil filter, about 1/4 of the pollutants in the old filter will re-circulate into the oil, which not only increases the chance of wear, but also reduces the Performance of new oil.
