When selecting a filter, original parts or a second brand can be used. It should be noted that the selected filter element should be inspected for compliance with its performance indicators.

Buying a car is not easy, so we need to take care of it carefully. During the warranty period of a new car, it is advisable not to use substitutes for filters. Even after the warranty period, filters should be carefully selected. A qualified oil filter must meet the original design requirements for engine cylinder pressure, oil temperature, flow rate, viscosity, and vehicle usage conditions, and consider the comprehensive balance of core quality. The performance of diesel filters is classified according to ISO standards. In addition to conducting performance tests according to SAE standards, the air filter must also undergo bench tests to meet the original intake resistance requirements of the engine's rated intake capacity. The hydraulic oil filter element is labeled with nominal filtration accuracy on the product sample or nameplate of the manufacturer, rather than absolute filtration accuracy. Only after passing the test can it be determined β The value represents the filtering ability of the filter. The hydraulic oil filter should also meet the requirements of pressure loss (the total pressure difference of the high-pressure filter is less than 0.1PMa, and the total pressure difference of the return oil filter is less than 0.05MPa) to ensure the optimization of flow rate and filter life.
