How To Choose Paper Oil Filter:

Appearance details: Oil filters produced by well-known brands are usually very exquisite in appearance details, with even paint spraying and smooth hand feel. However, inferior or counterfeit products often lack precision in appearance treatment, uneven paint spraying, and rough hand feel.

Filter paper density: The higher the density of filter paper, the better the filtering effect and the relatively better the quality. High quality oil filters typically use filter paper with higher density to ensure better filtration efficiency.

Weight: Good oil filters usually have a moderate weight. If the weight is too light, it may be due to the thin outer shell of the filter element, which is prone to deformation under high pressure and affects the filtration effect.

Sealing gasket: The high-quality sealing gasket for the inlet and outlet of the oil filter is thick and soft, ensuring good sealing performance. Poor quality rubber rings have a harder texture and insufficient elasticity.

Check valve and bypass valve: Check valves can block oil reflux, ensuring that the engine can quickly form oil pressure during cold start. The bypass valve can be opened when the oil filter is clogged to prevent engine dry friction. Checking the presence and function of these components is an important basis for determining the quality of the oil filter
