How to Distinguish True and False Car Oil Filter

Ⅰ. Introduction of car oil filter


The car oil filter is located in the engine lubrication system. The role of the car oil filter is to filter out harmful impurities in the oil from the oil pan, and to supply the crankshaft, connecting rod, camshaft, supercharger, piston ring and other motion pairs with clean oil. It plays the role of lubrication, cooling and cleaning, thereby extending the life of these parts.


Ⅱ. How to distinguish the quality of car oil filter


The excellent oil filter manufacturing companies products of car oil filter generally have the following points: 

1. The surface of the car oil filter is clearly printed with the factory logo, and the paint for printing has a good texture and is pure white. 

2. There is a bypass valve inside the car oil filter to ensure that there is a sufficient amount of oil supply in any state. 

3. The complex design of the car oil filter to suppress backflow ensures that the oil necessary for the next start is stored in the filter, and reduces the wear during cold start (all regular filters have this function). 

4. The car oil filter is equipped with a protective bag before leaving the factory. There is lubricating grease at the interface, the sealing material of the gasket is good, and the rubber parts are regular. 

5. The filter paper material of car oil filter is specially developed according to the oil used, and the density is moderate to ensure the filterability of the oil. 

6. The metal oil net form standard in the car oil filter element ensures the oil throughput. If the car oil filter is not selected correctly, the fake car oil filter will not only affect the normal oil supply and lubrication of the engine by the oil pump, but also due to rough manufacturing, the interface of the main oil passage may Insufficient sealing may occur, causing oil to burst from the interface between the engine filter and the cylinder block, resulting in engine oil leakage, poor engine heat dissipation, and other malfunctions. In severe cases, the cylinder may blow out.
