For machine filter、Air filter、Air conditioning filter，Everyone may be familiar with it，But the steam filter is often ignored。

Then，What is a steam filter? How often should a steam filter be replaced?

Let me take you to find out~

Steam filter/gasoline filter，Full name gasoline filter，It is a type of fuel filter。Can filter fuel impurities，Provide clean fuel to the engine，Is an important automotive component that protects the engine and fuel supply system。

Gasoline in production、During storage, transportation and use，Certain impurities such as iron oxide will seabet loginbe produced、Dust, etc.，Perhaps the quality of oil at some gas stations is inherently poor，Contains a large amount of impurities。

If these impurities are not filtered，will be brought into the engine and fuel supply system，Eventually damage the cylinder or cause the injector to become clogged。At this time，You need a car filter to filter out impurities，Ensure the normal operation of the vehicle。

Gasoline filter classification

Gasoline filters can be divided into two types: in-line fuel filters and built-in fuel filters。

Among them, the in-line fuel filter is our most common。It is outside the outer tank，Connected to the oil inlet pipe，The main function of the fuel inlet pipe is to transport fuel into the engine。The biggest advantage of the in-line fuel filter is that it is easy to replace。

And built-in fuel filter，Located inside the fuel tank，The replacement operation is more complicated，And the maintenance cost is relatively high，Therefore, it is not recommended for non-professionals to replace it privately，It is recommended that you go to a regular 4S store to find a professional technician for replacement。The biggest advantage of the built-in fuel filter is that the pass rate is very high，And not easy to clog。

How often should the gasoline filter be replaced

The replacement cycle of gasoline filter element is relatively long，Generally replace every 30,000-50,000 kilometers，The specific needs will depend on your maintenance manual or actual usage and gasoline quality。If the fuel impurity content seabet iois large，The probability of the gasoline filter becoming clogged will be greatly increased，The replacement cycle should be shortened appropriately。

Another thing to note is，If the car has the following symptoms，Other causes have been ruled out，It may be because your gasoline filter element is too dirty，Need to be replaced in time。

Fast acceleration and weakness，And the power drops obviously when the car is running under heavy load: the gasoline filter element is slightly clogged，Generally, it will cause poor oil supply to the engine，Resulting in a decrease in engine power。

Engine shaking when idling: gasoline filter is moderately clogged，Not only makes the car power worse，It will also cause the engine to vibrate when the car is idling。

Difficulty in starting or the car cannot start directly: When the gasoline filter is seriously clogged，The car may have difficulty starting or even fail to start，Sometimes it takes 2-5 times to light the fire。

Summary

Inferior quality gasoline filter，Not only the material is poor，And the filtering effect is poor。Soaked in gasoline for a long time，The filter element itself will have a filter layer falling off，Blocked oil line，Causing abnormal pressure in the fuel system，Ultimately causing irreversible damage to the vehicle。So don’t be greedy for cheap，Use inferior gasoline filter element。
