Gasoline filters are carburetor type filters and electric injection type filters. The filter element of the gasoline filter is mostly filter paper, and nylon cloth and polymer materials are also used.

The role of the gasoline filter
The impurities contained in the gasoline will damage the engine's fuel injection nozzle, fuel pump, fuel line and other components, affecting the operation of the fuel system. The gasoline filter mainly acts on the filtration of impurities in the fuel system to protect the normal operation of the engine with clean fuel.

Maintenance cycle of gasoline filter
As one of the vehicle filters, the gasoline filter belongs to the wearing parts. Most engines are equipped with disposable, non-removable, paper filter gasoline filters, which generally need to be replaced every 10,000 kilometers. In the case of high oil products, the filter can also be replaced once for 15000-20000 km. If the filter is not replaced for a long time, it will weaken the filter function and affect the working efficiency of the engine.

Gasoline filter between true and false
In general, the true and false of gasoline filters have several aspects:
Appearance: filter work and filter quality
Inferior gasoline filter, workmanship is relatively rough, the naked eye is easy to distinguish. The weight of the filter is also different, because of the different material of the filter, the inferior gasoline filter is generally lighter than the real filter.

Filter paper: Filter capacity varies
Filter paper, inferior gasoline filters, the filter materials used are generally not qualified. The filter cannot fully filter impurities, and the long-term use of these inferior filters will affect the normal operation of the engine fuel system.

Life: Filter life difference
Poor quality gasoline filters, the use of filter paper material is poor, the filter is easy to premature damage. In addition, the filter paper debris is easy to enter the gasoline, resulting in oil circuit blockage and gasoline pump damage.

The long-term use of inferior gasoline filters in vehicles increases the wear of various engine components, affects the service life of the engine, decreases the engine power, increases the fuel consumption, and increases the emission of harmful substances.
