The engine oil filter is mainly used to filter impurities in the engine oil, providing clean engine oil lubrication for various components, reducing friction loss, and improving engine work efficiency.
The oil filter is one of the vulnerable parts, and consumers need to replace the oil filter together every time they change the oil. Due to this characteristic of oil filters, there are many inferior products of oil filters in the market. Therefore, it is very important to distinguish the quality of oil filters when selecting them.

Poor quality oil filters can affect the normal oil supply and lubrication of the engine by the oil pump, and some counterfeit oil filters are poorly made, resulting in loose sealing at the interface of the main oil duct, causing oil to jump out at the interface between the oil filter and the cylinder block, leading to engine failure and, in severe cases, cylinder explosion. So when choosing an oil filter, we must carefully choose it.

Genuine engine oil filter:
1) The factory logo font on the surface of the genuine engine oil filter is clearly printed, and the paint used for printing has a good texture.
2) There is a bypass valve inside the oil filter to ensure oil supply.
3) The anti reflux design ensures that there is a certain amount of oil in the oil filter, reducing wear during cold start.
4) The oil filter is equipped with a protective bag before leaving the factory, and there is lubricating grease at the interface. The gasket sealing material is good.

Poor quality oil filter:
1) The font printing on the surface of the oil filter is blurry or not clear enough, and the font printing paint surface is of poor quality and thin.
2) There is no bypass valve inside the oil filter, and once the oil filter is blocked, the engine will not be able to obtain sufficient oil lubrication.
3) After stalling, there is no function to inhibit oil reflux, and engine wear during cold start will be greater.
4) The sealing material of the oil filter gasket is poor, which may cause oil leakage and even fire under high temperature and pressure.
5) The material of the oil filter paper is different, which cannot achieve the expected filtering effect.
6) The metal oil net is rough in workmanship, making it difficult to ensure sufficient oil flow.

The selection of oil filters has a significant impact on both oil and engines. Faced with the chaotic filter market, consumers should be cautious and not purchase non genuine products!
