How many kilometers should a gasoline filter be replaced?

Gasoline filter replacement depends on fuel quality. If the fuel quality is good, it can be replaced every 60,000 kilometers. The replacement method is as follows: 1. Park the car on a solid surface and reduce the fuel system pressure. The fuel injection system operates under very high pressure, so it is necessary to reduce the pressure. Loosen the valve cover to decrease the fuel system pressure and remove the fuel pump relay or fuse. 2. Start the engine until the gasoline in the pipeline is used up and the engine stops. Locate the gasoline filter, which is usually under the engine or fuel tank. If necessary, use a jack to lift the car and disconnect the fuel line. Note: For older cars with carburetors, the fuel line is a flexible hose with a spring. For newer fuel-injected engines, the fuel line is connected with clips or quick-lock couplings, which require special tools for removal. 3. Remove the installation bolts of the gasoline filter, then the filter can be taken out. Compare the new gasoline filter with the removed one to ensure they are the same model. After confirmation, install the new gasoline filter, paying attention to the direction to ensure it points toward the engine. Once confirmed, install the filter fixing bolts, reconnect the fuel line, and install the fuel pump fuse. Reconnect the battery box, then lower the car. Start the engine and check for fuel leaks. During actual driving, check if the engine is working sluggishly.
I've been paying attention to the replacement of the fuel filter since driving the family's old sedan, usually changing it every 30,000 to 50,000 kilometers. My car is mostly used for commuting, with smooth road conditions and good fuel quality, so I replace it during the 50,000-kilometer check-up and maintenance. However, if you frequently drive long distances or in dusty rural areas, it's best to change it every 30,000 to 40,000 kilometers to prevent impurities from clogging and affecting the fuel pump, which can lead to decreased engine power. Last time I delayed it and didn't change it until over 60,000 kilometers, resulting in severe engine shaking after refueling and costly repairs. In short, replacing the filter regularly saves both hassle and money—don't wait until problems arise to fix it.
