Liqui Moly Marine Super Diesel Additive is a premium, high efficiency treatment formulated to clean, protect and enhance the performance of all marine diesel engines. Its advanced blend of agents increases the cetane number, improving ignition quality and ensuring cleaner, more complete combustion. This leads to smoother running, reduced fuel consumption and noticeably stronger engine response under load.
The additive provides robust corrosion protection, shielding the entire fuel system from rust, moisture and the damaging effects of water contamination - an essential advantage for vessels operating in marine environments. Its powerful cleaning action keeps injection nozzles, pumps and internal components free from deposits, preventing injector needle sticking, gumming and premature wear. By maintaining a clean fuel system, it helps prevent the formation of harmful residues, supports long term reliability and extends engine life.
Fully compatible with all marine diesel engines, including common rail and pumped‑jet systems, this additive works seamlessly with conventional diesel, biodiesel blends, HVO and XTL fuels. The 1 Litre bottle treats up to 500 Litres of fuel, while each 25 ml dose is ideal for 12.5 Litres, making accurate dosing simple for both small craft and larger vessels.
Designed to deliver cleaner combustion, improved lubrication and high wear resistance, Marine Super Diesel Additive keeps your engine running at peak efficiency on every voyage.
