With the growth of the vehicle's service age, the increase of the driving mileage, the long-term operation of the fuel filter, and the reaching of a certain life cycle, will lead to weak acceleration, increased fuel consumption, increased noise, and reduced handling performance.
The recommended replacement cycle of fuel filter shall be different according to its own structure, performance and use, and cannot be generalized.
1. It is recommended to replace the fuel filter every 10000 km, and replace the fuel filter in the fuel tank every 40000~80000 km. Before purchasing goods, please be sure to check your car's model, displacement and other information to ensure that you can buy the correct model of accessories. You can query the car maintenance manual or use the "Self service" function.
2. During major maintenance, the fuel filter is generally replaced together with the engine oil, engine filter and air filter. The disassembly and replacement of the fuel filter is relatively complicated, so do not operate it by yourself easily.
3. High quality fuel filters are selected. Poor fuel filters often lead to poor fuel supply, insufficient power and even flameout. Impurities are not filtered. The oil circuit and fuel injection system will also be corroded and damaged after a long time.
4. When you feel that the vehicle speed is significantly reduced, the engine is not accelerating well, and the vehicle is driving weakly, you should think that the fuel filter may have been blocked, and you need to check and replace it in time.
