Liqui Moly Pro-Line Diesel System Cleaner is a high-performance additive formulated to remove troublesome deposits from injection nozzles, the entire fuel system and combustion chambers. It prevents nozzle needle sticking and gumming, improves ignition quality and optimises the combustion process to restore the engine’s original performance.
By reducing pollutant emissions and exhaust smoke, it can help optimise smoke opacity prior to an emissions test. Suitable for all diesel and turbocharged diesel engines with or without a diesel particulate filter (DPF). One 500ml can treats up to 70 litres of diesel fuel.
