It should be replaced approximately every 100,000 kilometers. Here is more information about fuel filters: 1. Built-in fuel filter: Only a few cars have this type, which is installed on the fuel pump and immersed in gasoline. This type of fuel filter has a long service life, and if the car is driven infrequently, it can be replaced after many years. However, due to its location, replacement is more complicated, requiring the fuel pump to be removed, and thus the labor cost is relatively high. 2. External fuel filter: The service cycle of an external fuel filter is relatively short, generally needing replacement every 10,000 to 20,000 kilometers. Most vehicles use this type of fuel filter, and its replacement method is also relatively simple.

The recommended replacement interval for the original fuel filter is generally every 30,000 to 40,000 kilometers or every two to three years, depending on vehicle usage. Having driven for over a decade, I find this frequency quite practical. If you frequently drive short distances in the city, fuel impurities tend to accumulate, and you might need to check it every 25,000 kilometers. Last time, I delayed until 35,000 kilometers before replacing it, and the engine struggled with acceleration. The mechanic said the filter was half clogged. Now I make it a habit to check the maintenance manual, which contains the manufacturer's recommendations. Environmental factors also play a significant role—dusty or rainy areas can dirty the fuel system faster, shortening the filter's lifespan. Regular replacement saves hassle and avoids major repairs later, as engine cleanliness is crucial. Proper maintenance can even slightly reduce fuel consumption.

As a car owner who pays close attention to vehicle condition, I always keep the replacement of the original fuel filter on my schedule, with the standard being every 35,000 kilometers or two and a half years. This component acts like a guardian angel for the engine, preventing impurities from clogging the fuel pump. If left unchanged for too long, you might experience sluggish starts or a noticeable drop in power. I neglected it recently and suddenly had difficulty accelerating while driving—after inspection, it turned out to be a filter issue. Replacing it immediately improved performance. I recommend adjusting the replacement interval based on fuel quality; if local gasoline contains more impurities, shorten the interval to 30,000 kilometers. New cars come with maintenance reminder lights, but don’t rely solely on them—manual checks are more reliable. Always use genuine parts for replacements to ensure better longevity and compatibility.

The fuel filter is a key component that filters out impurities in the fuel. The original one is generally durable and needs replacement every 35,000 kilometers. I've learned from automotive knowledge that driving habits have a significant impact. Frequent idling or short trips can accelerate impurity accumulation. If you notice difficulty starting the engine or abnormal increase in fuel consumption, these could be signals to replace it promptly. Choose a reputable repair shop for the operation and don't delay to prevent fuel line blockage and engine damage. Timely maintenance can save on repair costs.
