● Filter paper: the oil filter on the filter paper is higher than the air filter, mainly because the oil temperature change from 0 to 300 degrees, in the severe temperature change, the oil concentration will change accordingly, which will affect the filter flow of the oil. The filter paper of a high quality oil filter should be able to filter impurities under drastic temperature changes while ensuring sufficient flow.
● Rubber sealing ring: the filter sealing ring of high quality oil is made of special rubber to ensure 100% oil leakage.
● Backflow control valve: available only in premium oil filters. It prevents the oil filter from drying out when the engine is shut off; When the engine reignites, it immediately exerts pressure to lubricate the engine with oil. (also known as stop return valve)
