Red Line’s SI-1 Fuel System Cleaner is a concentrated package of the most powerful high-temperature detergents available. Together, these detergents clean gasoline fuel injectors, 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 treats up to 100 gallons, protects the fuel system from rust, and is safe for continual use on all gasoline vehicles.

The Best Performing Fuel System Cleaner currently available. Redline SI-1 is currently the best fuel system cleaner that is readily available. One of the best examples supporting this statement is represented by the condition of my 2003 S2000’s engine. I bought the car new and I’m responsible for essentially every one of the 99,700 miles on the clock. The earlier S2000s (1999-2003 model years – called the AP1) are notorious for oil consumption through the PCV valve (for a number of reasons), and as a consequence the intake manifold and throttle body…
