Fuel system cleaners are specialized products designed to remove deposits and contaminants from the fuel system of a vehicle. These deposits can accumulate in various components, such as the fuel injectors, intake valves, and combustion chambers, leading to reduced engine performance and efficiency. By using a fuel system cleaner, drivers can help maintain optimal fuel flow and improve overall engine function. Typically added to the fuel tank, these cleaners work by dissolving carbon buildup and other residues as the engine runs. Regular use of fuel system cleaners can enhance fuel economy, reduce emissions, and prolong the life of the engine, making them a valuable addition to vehicle maintenance.
