Cold-weather protection for your diesel fuel system
Opti-Lube Winter Cold Flow Anti-Gel Diesel Fuel Additive helps keep diesel flowing as temperatures drop. Its concentrated, multifunction formula helps prevent fuel gelling while improving lubricity to reduce wear on injectors, fuel pumps, and other fuel system components.
Winter cleans injectors, helps reduce deposits, and protects against rust and corrosion. Its demulsifier improves water separation, while added cetane supports easier cold starts, faster warm-ups, and smoother combustion. The formula also helps improve fuel economy and fuel storage stability.
