When is the gasoline filter changed?
Fuel oil will be mixed with some impurities during production, transportation and refueling. Impurities in the fuel will block the fuel injection nozzle, and impurities will be attached to the inlet, cylinder wall and other parts, resulting in carbon deposition, resulting in poor engine working conditions. The fuel filter element is used to filter impurities in the fuel, and it must be replaced after a period of use to ensure better filtration effect. Different brands of vehicle fuel filter replacement cycle will also be slightly different. In general, the external steam filter can be replaced when the car travels about 20,000 kilometers every time. The built-in steam filter is generally replaced once at 40,000 km.
