Red Line SI-1 Complete Fuel System Cleaner – 443ml • 60103

Red Line concentrated petrol fuel-system cleaner for compatible fuel-injected and carburetted petrol engines.

Red Line SI-1 Complete Fuel System Cleaner is designed to remove and control deposits throughout the petrol fuel system. Its detergent formulation targets fuel injectors, carburettors, intake valves and combustion chambers to support fuel-system cleanliness and consistent engine operation.

SI-1 contains high-temperature detergents together with upper-cylinder lubricant. It can be used as a concentrated cleaning treatment or at a lower maintenance concentration, following the dosage instructions printed on the physical container.

Each bottle contains 443ml / 15 US fl oz. Add the appropriate measured quantity directly to the petrol fuel tank. The correct dose depends on the amount of fuel being treated and whether the product is being used for routine maintenance or concentrated cleaning.

Common reasons for use include routine fuel-system maintenance, cleaning deposits from injectors or carburettors, treating deposit-related hesitation or uneven running, and servicing petrol-powered vehicles that have experienced prolonged or inconsistent use. This additive cannot repair failed injectors, damaged fuel pumps, ignition faults, low compression or other mechanical defects.
