How Often Should the Car Fuel Filter Be Replaced?
2 Answers
Car fuel filters should be replaced every 40,000 kilometers or every two years. The method for replacing a fuel filter is as follows: 1. Close the inlet valve of the filter, unscrew the end cover bolts, and open the end cover; 2. Open the drain valve to completely drain the dirty oil; 3. Loosen the tightening nut at the top of the filter and remove the old filter vertically upwards; 4. After replacing the filter, close the drain valve and secure the end cover with bolts. The function of the fuel filter is to filter impurities in the gasoline, preventing clogging of the fuel injector and wear on the fuel injector components. Maintenance methods for the fuel filter include: 1. Adding fuel cleaner; 2. Using gasoline with the octane rating suitable for the engine requirements.
I've been running an auto repair shop for many years, and I've seen cases where not changing the gasoline filter for too long leads to trouble—the engine won't start or it shakes while running. Generally, I recommend replacing it every 30,000 kilometers or every two years for optimal safety. But this isn't a hard rule—it depends on how dusty your driving environment is. If you frequently drive in polluted urban areas, you might need to replace it as early as 20,000 kilometers. During replacement, check if the fuel system connections are loose to prevent unexpected breakdowns. The key is not to skimp on this small expense—if the filter gets clogged, not only will fuel consumption increase, but it could also damage the fuel injectors, leading to costly repairs. During regular maintenance, always remember to check the filter—proper upkeep extends the engine's lifespan.
