Oil filter function
The function of the oil filter is to filter the metal debris in the engine and various impurities in the oil to prevent the deterioration of the oil and avoid the wear of the engine moving part; In addition, when the oil filter is blocked, let the oil flow properly to ensure that the oil pressure is normal.
The oil filter generally requires 5,000 kilometers to be replaced once in order to achieve the best use effect.

Oil filter should have the performance
(1) Quality conditions to maintain performance:
A, high filtration performance (filtration efficiency);
B, low pressure loss rate; C, long life (large capture)

(2) Quality conditions with durability and rationality:
A, pressure resistance, vibration resistance, high durability, will not leak oil;
B, low temperature resistance (-40℃), high temperature resistance (+140℃), high-quality filter paper, adhesive and rubber will not melt, and there will never be leakage of oil;
C, loading and unloading is simple and light.
