Engine cleaners are specially formulated products designed to remove dirt, carbon deposits, and sludge from the internal components of your vehicle's engine. When you add an engine cleaner to your fuel system, it travels through the engine and breaks down harmful deposits using powerful detergents and solvents. These ingredients work by loosening the buildup that accumulates over time, particularly in critical areas such as fuel injectors, valves, and combustion chambers. As the cleaner is burned during the engine's operation, it helps to flush out these contaminants, improving overall engine performance and efficiency. Regular use of engine cleaners can also enhance fuel economy and reduce harmful emissions, keeping your engine running smoothly and extending its lifespan.
