How many kilometers should the fuel filter of a car be replaced?

Generally, the fuel filter of a car should be replaced every 60,000 kilometers. Here is more information about the fuel filter: 1. Gasoline is made from crude oil through a complex process, then transported to various gas stations through a special route, and finally delivered to the owner's fuel tank. During this process, impurities in the gasoline inevitably enter the fuel tank. 2. As the usage time extends, the impurities will also increase. As a result, the filter used to filter the fuel will become dirty and filled with residue, significantly reducing the filtration effect. 3. It is recommended to replace the filter when the specified mileage is reached. If not replaced or delayed, it will inevitably affect the car's performance, causing issues such as poor fuel flow and weak acceleration, ultimately leading to chronic engine damage or even requiring a major engine overhaul.
I've been driving for over a decade. For small cars, it's generally recommended to replace the gasoline filter every 30,000 to 50,000 kilometers, depending on your vehicle and driving habits. The manufacturer's manual is the most reliable reference. For example, my old car's manual suggested replacement every 40,000 kilometers, and I followed that schedule, maintaining stable performance. However, if you frequently encounter city traffic congestion or the fuel quality at gas stations is poor, impurities can accumulate more quickly, potentially requiring inspection as early as 25,000 kilometers. The filter's role is to trap contaminants in the gasoline, preventing clogged fuel injectors or impaired engine combustion. Delaying replacement can lead to increased fuel consumption, sluggish acceleration, and in severe cases, engine stalling. Therefore, I recommend reminding your mechanic to check the filter's condition during each maintenance service. Don't wait until problems arise, as that can be costly and time-consuming. Typically, replacing a filter is inexpensive, ranging from tens to a hundred yuan, far more economical than major engine repairs. Remember, safe driving starts with these small maintenance tasks.
