The Liqui Moly Pro-Line Super Diesel Additive is a high-performance diesel fuel treatment designed to clean, protect, and optimise the entire diesel fuel system. Specially developed for modern low-sulfur diesel fuels, including blends containing biodiesel, this advanced additive improves combustion efficiency, boosts cetane levels, and helps maintain peak engine performance. Its powerful cleaning agents effectively remove and prevent harmful deposits in injectors and fuel system components, while advanced lubricity enhancers help protect injection system parts from wear caused by low-sulfur diesel fuel. The formula also provides exceptional corrosion protection, helping extend the life of fuel system components and reduce the risk of costly repairs. By improving ignition performance and combustion quality, Liqui Moly Pro-Line Super Diesel Additive helps reduce exhaust emissions, improve engine smoothness, and maintain reliable diesel engine operation under demanding conditions.
