Red Line's SI-1 fuel injector and valve detergent is a concentrated package of the most powerful high-temperature detergents available to clean gasoline fuel injectors or carburetors, intake valves and combustion chambers and can clean injectors to nearly 100% efficiency in one treatment. The cleansing effect on injector deposits can raise fuel economy approximately 12% or even greater, depending on the condition of the injectors.
SI-1 also contains detergents and a synthetic upper cylinder lubricant which will help clean pollution control valves and can reduce octane requirements by two numbers. SI-1 also protects the fuel system from rust.
Use one bottle with a full tank or use in smaller doses for continued maintenance, as SI-1 treats up to 100 gallons. This product is safe for continual use.
