What additive keeps engine clean by?

An additive that helps keep engines clean is a fuel injector cleaner, which typically contains detergents that remove carbon deposits and other impurities from the fuel system. Regular use of these cleaners can prevent buildup in fuel injectors, intake valves, and combustion chambers, promoting better engine performance and efficiency. Additionally, engine oil additives can also help maintain cleanliness by suspending contaminants and preventing sludge formation.
