How to distinguish true and false oil filter?

The oil filter is our common car wear and tear, and it must be replaced with the oil for several thousand kilometers. Regardless of the price of this small part is not expensive, but it plays a decisive role in the normal operation of the engine. If something goes wrong, it will increase fuel consumption and aggravate the wear and tear of the engine; at the worst, it will cause the engine to be scrapped and suffer heavy losses. The factory logo of the real oil filter is clearly printed, and the paint used for printing has good texture and is pure white. There is a bypass valve inside to ensure that there is a sufficient amount of oil supply in any state. Complicated reflux suppression design, the oil necessary for the next start is stored in the filter of the machine, which reduces the wear during cold start. It is equipped with a protective bag before leaving the factory, with lubricating grease at the interface, the gasket is made of good sealing material, and rubber rule.

The filter paper material has a moderate density to ensure the filterability of the oil. However, the font printing on the surface of the fake oil filter is blurred or not clear enough, and the surface of the font printing paint is inferior and thin. Without the bypass valve, once the filter is clogged, the engine will not be able to obtain sufficient oil lubrication. The sealing material of the gasket is poor, and it may cause oil leakage under high temperature and high pressure, and even cause fire. The material of the filter paper is different, it is difficult to achieve the predetermined filtering effect.
