A Fuel System Cleaner is a specialized product designed to remove deposits and contaminants from the fuel system of a vehicle. It works by cleaning components such as the fuel injectors, carburetors, and intake valves, helping to improve fuel efficiency and engine performance. Regular use can prevent issues like rough idling and reduced power. These cleaners are typically added to the fuel tank and mixed with gasoline or diesel. They contain detergents and solvents that break down carbon buildup and other residues. Using a Fuel System Cleaner can lead to smoother engine operation and may extend the life of the vehicle's fuel system components.
