The Liqui Moly Marine Fuel Stabiliser is a premium additive formulated to preserve petrol used in marine engines, boats, jet skis, and long-storage fuel systems. Designed to prevent fuel ageing, oxidation, and corrosion, this stabiliser protects the entire fuel system during periods of inactivity or seasonal storage. Its modern, ash-free formulation maintains petrol stability — even fuels containing bio-ethanol — ensuring easy engine startup after storage and preventing costly fuel-related damage. Suitable for all 2-stroke and 4-stroke petrol marine engines, this additive is simple to use, highly effective, and cost-efficient thanks to its precise dosing.
