How often should the fuel filter be changed?

I believe many people have such a question, how often is the most appropriate time to replace the fuel filter. According to the owner’s manual, it only needs to be replaced once every 60,000 kilometers, but the Internet suggests that it is best to replace it once every 20,000 kilometers. A very different answer seems to put us in a dilemma again.
Fuel filter is used to filter impurities in automobile fuel. It is one of the “three filters” we often say. According to different fuels, it can be divided into gasoline filter and diesel filter, which are wearing parts. One, it needs to be cleaned and replaced regularly. Generally, the fuel of private cars is mainly gasoline, so the filter is also a gasoline filter.

As we all know, gasoline is refined from crude oil through a complex process, and then transported to various refueling stations through special channels, and finally to the fuel tank of a private car. In this process, the impurities in gasoline will inevitably enter the fuel tank, and the impurities will also increase with the prolongation of use time. In this way, the filter used to filter the fuel will be dirty and full of dregs, so the filtering effect will be greatly reduced. Therefore, it is recommended to replace it when the number of kilometers is reached. If it is not replaced or delayed, it will definitely affect the performance of the car, resulting in poor oil flow, lack of refueling, etc., and eventually lead to chronic damage to the engine, or even overhaul of the engine. This cost can be worth the price of how many fuel filters.

So, what exactly is the replacement cycle of the fuel filter?
In fact, the fuel filter must be replaced every 30,000 kilometers under normal use. If the fuel impurity content is large, the driving distance should be shortened accordingly. But in general, we recommend replacing it every 20,000 kilometers. For the best replacement time, please refer to the instructions in the vehicle manual.
Usually, the replacement of the fuel filter is carried out when the car is undergoing major maintenance, and the air filter and oil filter are replaced at the same time. But in reality, it can be appropriately extended according to the situation of the car engine, because the current gasoline production technology level is relatively high, and the process from production to sales is relatively closed. Kilometers are no problem.

When replacing the filter, do not choose an inferior fuel filter, because the filter element used in the inferior fuel filter is of poor material, which not only has poor filtering effect, but is soaked in oil for a long time. Road, resulting in insufficient fuel pressure, the vehicle can not start. At the same time, it will also cause abnormal pressure in the fuel system, which will directly lead to insufficient engine power or insufficient combustion, damage to valuable components such as three-way catalytic converters and oxygen sensors, and cause huge economic losses.
