How many kilometers should a car's fuel filter be replaced?

[DiAaron]

To ensure the effective protective function of the fuel filter, it is generally recommended to replace it every 10,000-20,000 kilometers. Of course, the actual situation should be taken into consideration. When the filter element inside the fuel filter shows obvious blackening, it indicates that replacement is needed promptly. Effects of a dirty fuel filter: 1. Prone to stalling: After the fuel filter is clogged, fuel delivery is affected, leading to insufficient fuel supply to the engine. This results in noticeable jerking during driving or gear shifting, unstable idling, and a tendency to stall. 2. Reduced driving power: Due to poor fuel supply, the engine's power output decreases, causing the vehicle to lack power and reducing speed. For example, a car that could reach speeds above 100 km/h may drop to 70-80 km/h. 3. Increased mechanical wear: Over time, unfiltered impurities can corrode and damage the fuel lines and fuel injection system.
