The type of material used for the filter and the construction of the filter element used depend on the design requirements of the vehicle type for which the filter itself is intended. Not that heavier materials are more suitable for all vehicles. Different types of oil filters have different requirements.
For example, for the same auto oil filter, if you choose a heavier weight filter material, it may greatly increase the flow resistance and reduce the flow rate, thus increasing the energy consumption during vehicle driving, or even unable to achieve the engine oil flow rate. The demand for oil leads to insufficient oil lubrication. Therefore, the auto oil filter is not the heavier, the better.
For example, the sealing performance of a spin-on filter mainly depends on the performance of the sealing ring and the strength of the housing. It's not the heavier, the better. Some people think that the heavier the spin-on filter and the thicker the housing material used, the better the sealing performance. In fact, this statement is not comprehensive.
Each filter has an applicable working pressure range, as long as the pressure bearing capacity of the filter has enough remaining capacity for its working pressure. Choosing a too heavy auto oil filter will increase unnecessary costs, and at the same time will overload the vehicle and increase energy consumption. It is unreasonable from the perspective of environmental protection and cost performance.
In addition, the performance of the sealing ring of the auto oil filter and the strength of the shell depend to a large extent on the selected materials and the structural design of the parts.
