Wynn's Advanced Dual Fuel Gasoline and Diesel Fuel Cleaner, Treatment, and Moisture Remover from Belgian company Wynn's Wynn’s® Advanced Dual Fuel is a revolutionary formulation that helps remove water accumulated in gasoline and diesel fuel systems and prevents contamination. Gasoline and diesel fuel tanks collect water throughout the year due to humid conditions or contamination of underground storage tanks. Ethanol-blended fuels are highly hygroscopic. This causes fuel to absorb more water. Excess water in fuel can lead to phase separation, which may reduce octane rating and cause engine knocking. This professional formulation stabilizes both gasoline and diesel fuels, dissolving and suspending water for removal through the combustion process. Advanced Dual Fuel protects the metal surfaces of your vehicle from corrosion and helps prevent hesitation and poor acceleration caused by water contamination.
