Effect

The function of the fuel filter is to remove the iron oxide, dust and other solid impurities contained in the fuel to prevent the fuel system from clogging (especially the fuel injector). Reduce mechanical wear, ensure stable engine operation, and improve reliability.

Replacement cycle

1. The fuel filter is recommended to be replaced every 10,000 kilometers, and the built-in fuel filter in the fuel tank is replaced by 40,000 to 80,000 kilometers. There may be slight differences in the maintenance cycle between different models. When your car needs to be replaced and maintained, please use the “Maintenance Inquiry” function to find out.

2. During major maintenance, the fuel filter is generally replaced at the same time as the engine oil, engine filter, and air filter.

3. When you feel that the vehicle speed is significantly reduced, the engine is not accelerating poorly, and the vehicle is running weak, you should think that the fuel filter may be blocked and you need to check and replace it in time.

The need for replacement

Fuel filters can be divided into gasoline filters and diesel filters according to different fuels. The main choice for household vehicles is gasoline filters, and gasoline filters are divided into internal and external fuel tanks. As the age of the vehicle increases, the mileage increases, and the fuel filter works for a long time and reaches a certain life span, which will cause the vehicle to accelerate weakly, increase fuel consumption, increase noise, and reduce control functions.
