SI-1's injector and valve detergent is a concentrated package of the most powerful high-temperautre detergents available to clean petroleum fuel injectors, intake valves and combustion chambers. SI-1 Complete Fuel System Cleaner 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. Athough many petroleums advertise injector cleanliness, GM presented a paper to the SAE which indicates that their customers encountered injector plugging with all major brands of petroleum (SAE 861533).

SI-1 also contains detergents and a synthetic upper cylinder lubricant which will help clean the intake valves, pollution control valves, combustion chamber deposits and carbuetors. One bottle of SI-1 to a tank of fuel can reduce octane requirements by two numbers. SI-1 also protects the fuel system from rust. One bottle treats up to 100 gallons. Safe for continual use.

Also available as SI-2, the same formula in a single dose of 118ml bottle - perfect for motorcycles too.
