Red Line Synthetic Oil SI-1 Fuel System Cleaner is a concentrated fuel-system treatment formulated to clean deposits from fuel injectors, carburetors, valves, and combustion chambers. Its advanced blend of high-temperature and low-temperature detergents helps clean nearly all types of fuel injectors, including gasoline direct injection (GDI) systems, while supporting improved fuel-system performance.
Use one 15 US fl oz bottle per fuel tank for the most effective treatment. SI-1 helps enhance fuel stability and reduce the formation of gum and varnish during operation or storage. It can also reduce the need for higher-octane fuel by up to two octane points, depending on vehicle condition and fuel quality. The formula includes a synthetic upper-cylinder lubricant to help protect and lubricate upper-engine components.
Red Line Synthetic Oil SI-1 is suitable for vehicles equipped with pollution-control valves and is compatible with oxygenated gasoline. It is safe for continual use when applied according to the vehicle and product instructions. This fuel-system cleaner is designed for gasoline-powered cars, trucks, SUVs, and other compatible engines requiring deposit control and fuel-system maintenance.
Fitment: Suitable for most gasoline fuel systems, including carbureted, port-injected, and GDI applications. Confirm compatibility with the vehicle manufacturer’s fuel and maintenance requirements before use.
