Does gasoline really need detergents?

Yes! Detergents are added to gasoline so that it can help clean and protect your vehicle’s fuel delivery system, including the carburetor or fuel injectors, intake valves and intake port areas. A gasoline detergent is a lot like a household detergent, helping to prevent any harmful deposit build-up. Gasoline detergents can do such a great job at keeping critical engine components clean that the Environmental Protection Agency (EPA), through the Clean Air Act, has required them to be added to all gasolines since 1995.
