How Often Should the Car Fuel System Be Cleaned?

[AlessandraFitz]

Cleaning the car fuel system is typically recommended every 30,000 to 40,000 kilometers. Detailed information about fuel system cleaning is as follows: Symptoms indicating the need for cleaning: If symptoms such as unstable engine idle, fluctuating RPM, sluggish driving performance, or increased fuel consumption occur, it may indicate severe engine carbon buildup, and cleaning the car fuel system is advised. Reasons for cleaning: Fuel inherently contains impurities. If the pipelines from the fuel tank to the engine combustion chamber are not cleaned for an extended period, carbon deposits and sediments can clog the injector needle valves and valve orifices, affecting the performance of the precision components in the injection system. This can lead to poor fuel injection, inadequate atomization, or even no injection at all. Consequently, issues such as unstable idle, increased fuel consumption, poor acceleration, and difficulty starting may arise.
