The oil filter, also known as the oil grid, is mainly used to remove impurities such as dust, metal particles, carbon sediments and soot particles in the oil, so as to protect the engine. It is a frequently replaced part in vehicle maintenance and plays a vital role in keeping the lubricating oil clean and the engine running normally.

01 Harm of using inferior oil filter

The inferior oil filter not only affects the normal oil supply lubrication of the oil pump to the engine, but also some fake oil filters are shoddy, the interface of the main oil channel may have a lax seal, resulting in oil leakage in the combination of the oil filter and the cylinder body, resulting in oil leakage, poor engine heat dissipation and other failures, and in serious cases, cylinder explosion will occur. Therefore, when choosing an oil filter, we must choose the right product to ensure safety.

02 The difference between true and false oil filters

01 Features of authentic oil filter

(1) Authentic oil filter surface factory standard font printing is clear, printing paint texture is good.

(2) The internal bypass valve is provided to ensure that there is a sufficient amount of oil supply under any state.

(3) The complex reflux suppression design ensures that the oil filter contains the necessary oil for the next start, reducing wear during cold start (all factory filters have this function)

(4) Before the factory is equipped with a protective bag, lubricating butter at the interface, the sealing material of the gasket is good, and the rubber parts are regular.

(5) The shape standard of the metal oil mesh in the filter paper filter element to ensure the amount of oil passing.

(6) The material is specially developed according to the oil used, and the density is moderate to ensure the oil filterability.

02 Characteristics and hazards of non-genuine oil filters

(1) The font on the surface of the oil filter is fuzzy or not clear enough, and the paint surface of the font printing is inferior and thin.

(2) Without a bypass valve, once the oil filter is blocked, the engine will not be able to get enough oil lubrication.

(3) There is no inhibition of oil return function after extinguishing, and the engine wear will be greater when cold starting.

(4) The density and material of the gasket is poor, which may cause oil leakage under high temperature and pressure, and even lead to fire.

(5) The material of filter paper is different, and it is difficult to achieve the predetermined filtering effect.

(6) The metal oil mesh is rough, and it is difficult to ensure the abundance of oil.

03 The role of oil filter

01 Filter out harmful impurities

The oil filter can effectively filter out harmful impurities in the oil from the oil pan, and protect the various key parts of the engine, such as the crankshaft, connecting rod, camshaft, supercharger and piston ring and other moving accessories, to prevent them from being damaged.

02 Lubrication, cooling, cleaning function

The oil filter can ensure the cleanliness of the oil and provide good lubrication, cooling and cleaning for the engine, thereby extending the service life of these parts.

03 Avoid engine wear

Choosing a poor quality oil filter may cause impurities in the oil to enter the engine compartment, eventually leading to serious engine wear and need to be returned to the factory for overhaul. Therefore, it is very important to choose a high-quality oil filter.
