Does Replacing the Gasoline Filter Save Fuel?

[VonPaislee]

Replacing the gasoline filter does not save fuel. The primary function of the gasoline filter is to remove impurities from the fuel, preventing clogging of the carburetor or fuel injectors. If not replaced for a long time, excessive impurities can lead to pipe blockage or poor fuel supply, but it does not cause increased fuel consumption. The maintenance methods for the gasoline filter include: 1. Adding fuel cleaner. 2. Using gasoline with the octane rating suitable for the engine. The steps to replace the vehicle's gasoline filter are: 1. Close the inlet valve of the filter, unscrew the end cover bolts, and open the end cover. 2. Open the drain valve to completely drain the dirty oil. 3. Loosen the tightening nut at the top of the filter and remove the old filter vertically upwards. 4. After replacing the filter, close the drain valve and secure the end cover with bolts.
