Red Line SI-1 Fuel System Cleaner is a concentrated cleaner for injectors, carburetors, valves and combustion chambers that uses high- and low-temperature detergents to restore fuel stability and reduce gum and varnish. One bottle per tank is recommended for most treatments; it cleans GDI and other injector types, reduces octane need by up to two points, supplies synthetic upper-cylinder lubrication and is safe for continual use with oxygenated fuels.
Red Line SI-1 Fuel System Cleaner - 15oz.
