How often should fuel system cleaner be added?
2 Answers
Fuel system cleaner should be added every 5,000 kilometers. More information about fuel system cleaner is as follows: 1. Introduction: Fuel system cleaner is a general term for cleaning agents that remove carbon deposits, gum, and sludge from fuel injectors, intake valves, cylinder walls, piston tops, and intake pipes. Using such products can significantly reduce harmful emissions from vehicle exhaust, help vehicles pass exhaust tests, restore engine power, and improve engine efficiency and fuel economy. 2. Product benefits: Removes gum and dirt from the fuel system; Saves fuel and reduces exhaust emissions; Protects engine components and effectively prevents corrosion and rust.
I've been driving for over a decade and always pay attention to maintenance. As for fuel system cleaners, adding one every 5,000 to 10,000 kilometers is generally sufficient. New cars don't need it for the first couple of years—start using after driving 20,000-30,000 kilometers. Monitoring engine condition is crucial: if you notice slower acceleration, unexplained increased fuel consumption, or obvious idle vibration, it might indicate carbon buildup, and you should add a bottle promptly. I prefer adding it before long trips—the cleaning effect is excellent after highway driving since high engine temperatures help burn off carbon deposits. Always choose reputable brands; avoid random products recommended at gas stations.
