The replacement cycle of the fuel filter is 30000~50000 km. Because the role of the fuel filter is to remove the iron oxide, dust and other solid impurities contained in the fuel, prevent the fuel system from blocking, reduce mechanical wear, ensure the stable operation of the engine, and improve reliability. After long-term use, the fouling will seriously affect the filtering effect. If the fuel filter is too dirty or blocked, the engine will be unable to accelerate when accelerating The phenomenon of difficulty in starting requires regular inspection and replacement.

1. It is recommended to replace the fuel filter (combustion filter) every 10000 km, and the fuel filter in the fuel tank every 40000 to 80000 km. The maintenance intervals may vary slightly between different models. Please understand when your car needs to be replaced and serviced through the 'Self Service' function. During major maintenance, the combustion filter is usually replaced at the same time as the engine oil, machine filter, and air filter. The disassembly and replacement of the filter screen is quite complex, and it should not be operated easily by oneself. It needs to be operated and installed by professional personnel in a specialized store.

2. Necessity of replacing fuel filter (combustion filter) fuel filter can be divided into gasoline filter and diesel filter according to different fuels. Domestic cars mainly use gasoline filters, which are divided into internal and external fuel tanks. With the increase of vehicle age and driving mileage, long-term use of the fuel filter will lead to sluggish acceleration, increased fuel consumption, increased noise and reduced handling performance.

3. Precautions for selecting fuel filter (combustion filter)
(1) Before purchasing a product, please be sure to verify the model and displacement of your car to ensure that you can purchase the appropriate type of accessory. You can check the car maintenance manual or use the "self maintenance" function according to the car maintenance worry free website.
(2) During major maintenance, the fuel filter is usually replaced together with the engine oil, engine filter and air filter.
(3) Choose a high-quality fuel filter. Poor fuel filter often leads to poor fuel supply, insufficient power and even flameout. Impurities are not filtered, and over time, the oil circuit and fuel injection system will also be corroded and damaged.
(4) When you feel a significant decrease in vehicle speed, poor engine acceleration, and inability to drive, you should think that the combustion filter may be blocked and need to be checked in a timely manner.
