Is Fuel System Maintenance Necessary for Engines?
2 Answers
To avoid increased fuel consumption and ensure normal engine startup and operation, it is essential to maintain the vehicle's fuel system. Reasons for maintenance: After prolonged use, the fuel system can become obstructed or clogged due to dust in the air and impurities in gasoline. Additionally, carbon deposits and gum formed during combustion can adhere to the intake and exhaust valves, intake and exhaust passages, throttle body, and combustion chamber—especially on the fuel injector nozzles. This can lead to clogged or sticky injectors, causing fuel leakage, poor atomization, or even complete failure to spray fuel. As a result, fuel consumption increases, engine power decreases, idle becomes unstable, acceleration performance deteriorates, and starting difficulties arise. Maintenance precautions: Regular fuel system maintenance is necessary, but it should not be neglected nor performed too frequently.
As a veteran driver with over 20 years of experience, I believe engine fuel system maintenance is quite important. My previous old car developed issues like rough idling and poor acceleration before even reaching 100,000 kilometers because I neglected this. The mechanic found caked carbon deposits on both the fuel injectors and intake valves. Now I add a bottle of fuel system cleaner every 20,000 km and do regular fuel line cleaning - my current car's engine still runs smoothly at 150,000 km. Of course it depends on usage - my neighbor who mainly drives on highways rarely needs such maintenance. The key factor is driving conditions: if you frequently deal with city traffic congestion or use gas from small stations, regular maintenance can save you from costly major repairs.
