The service life of fuel filter varies according to different types. Generally, the external type (separate filter) requires replacement every 10000-10000 km, while the integrated type (filter integrated with the oil pump) requires replacement every 60000 km.

The service life of fuel filter varies according to different types. Generally, the external type (separate filter) requires replacement every 10000-10000 km, while the integrated type (filter integrated with the oil pump) requires replacement every 60000 km. If the quality of oil products is stable and guaranteed (such as long-term use in first tier cities), the replacement cycle can be appropriately extended. If the fuel injector is not replaced all the time, the first one affected is the fuel injector. Data shows that more than 90% of the fuel injector failures are caused by the fuel filter. If the fuel is not filtered thoroughly, the impurities and particles in the fuel will exacerbate the wear and tear of the entire fuel injection system (fuel injection pumps and nozzles, now the injection system is becoming more advanced, and the high-pressure oil pump used in the direct injection system produces oil pressure that is even dozens of times higher than that of ordinary electronic injection, requiring higher requirements).

After the fuel filter is blocked, the fuel supply will be insufficient, which will make the engine intermittently cut off fuel and affect the power output, and even the engine will stop or start difficultly. When purchasing filter cartridges, remember to choose high-quality ones and never seek small gains. Nowadays, there are many high quality counterfeit products in daily life. Although they may look similar in appearance, the actual products are not eye-catching. They will not have a filtering effect and will damage the engine. Therefore, when purchasing, it is important to keep your eyes open. The gasoline filter element plays a significant role, and it is necessary to replace the filter element during maintenance, because only by frequently changing the filter element can the working environment of the engine improve and the fuel supply pipe not be blocked.
