Is it necessary to add fuel system cleaner?

[Muhammad]

It is necessary to add fuel system cleaner when the fuel system is not clean. Additional information: After prolonged use, dust in the air and impurities in gasoline can cause fuel line blockages or poor flow. Carbon deposits on piston tops and cylinder heads can lead to localized overheating in the combustion chamber, gasoline pre-ignition, resulting in engine knocking, increased fuel consumption, reduced engine power, unstable idle, poor acceleration, and starting difficulties. These issues can shorten engine lifespan. Fuel system cleaners are essentially a general term for cleaning agents that remove carbon deposits, gum, and sludge from fuel injectors, intake valves, cylinder walls, piston tops, and intake manifolds. Using these products can significantly reduce harmful emissions, help vehicles pass emission tests, restore engine power, and improve engine efficiency and fuel economy.
