Is it necessary to change the fuel filter？ Car owners must watch! Without changing the filter, the performance of the car plummeted by 50%

In automobile maintenance, the fuel filter is often neglected, but its importance to the engine cannot be underestimated. Many car owners wonder: Do you want to replace this seemingly inconspicuous part? Let’s discuss this problem in depth together.

The function of fuel filter is to filter impurities in gasoline and ensure that the fuel entering the engine is clean and pure. With the increase of service time, the filter will be blocked gradually, which will affect the fuel supply and eventually lead to the decline of engine performance. Therefore, it is not only necessary to change the fuel filter regularly, but also very important to maintain the car.

First, the hazards of filter clogging

If the fuel filter is not replaced for a long time, it will lead to insufficient oil supply for the engine and cause many negative effects. First of all, the engine power is obviously reduced, and the acceleration is weak, especially when climbing or overtaking. Secondly, the fuel consumption will increase significantly, and the same journey may consume 10%-20% more fuel. More seriously, the fuel system may be damaged and the repair cost is high.

Some car owners reported that their car failed to change the fuel filter for three years, which led to the engine failure light, and the repair cost exceeded 5,000 yuan. This lesson tells us that a small maintenance negligence may bring huge economic losses.

Second, the replacement cycle and cost

Generally speaking, the replacement period of fuel filter is 30,000-50,000 kilometers or 2-3 years, depending on the vehicle type and the use environment. High-end models may have a longer service life, and in areas with poor air quality, they may need to be replaced more frequently.

The cost of replacing the fuel filter is not high, usually between 100-500 yuan. Compared with the possible engine damage, this investment is insignificant. Some car owners said that after changing the filter regularly, they obviously felt that the car had more power and reduced fuel consumption, saving at least the fuel cost in 100 yuan every month.

Third, self-inspection and maintenance skills

Although it is not recommended to replace the fuel filter by yourself, the owner can judge whether it is necessary to replace it by some simple methods. For example, if the vehicle is found to have weak acceleration, unstable idle speed or sudden increase in fuel consumption, it is likely to be a signal that there is a problem with the filter.

In addition, developing good car habits can also extend the life of filters. Try to refuel at regular gas stations to avoid using inferior fuel. Clean the oil tank regularly to prevent impurities from accumulating. Before long-distance driving, it is best to fill up the fuel tank to reduce the chance of air entering the fuel tank.

Some car owners shared a small coup: every time you refuel, first add a small bottle of fuel additive, which can effectively clean the fuel system and extend the service life of the filter. Although this will increase some costs, in the long run, it can save more maintenance costs.

The fuel filter may seem unremarkable, but it is important to protect the engine. Regular replacement can not only maintain vehicle performance, but also avoid unnecessary losses. As responsible car owners, we should pay attention to every detail and keep our car in the best condition.
