Diesel Winter Additive for Cold Weather Anti-Gel and Engine Protection

STA-BIL Diesel Winter is your cold-weather defence against fuel gelling, corrosion, and hard starts in freezing temperatures. Specially formulated for use in harsh winter climates, this diesel additive ensures your fuel flows freely and your engine starts reliably—even in extreme cold. With anti-gel protection down to -40°F (-40°C), it lowers the cold filter plug point by up to 36°F, helping to prevent frozen fuel lines and filters when you need your engine most.

Unlike competing products that disperse water into the fuel, STA-BIL Diesel Winter uses advanced **de-emulsification technology**, effectively separating water from the fuel so it can be properly removed by the fuel water separator. This prevents corrosion and ensures your fuel system functions efficiently. It also contains strong detergents to clean and lubricate injectors and fuel pumps, promoting smooth combustion and extending engine life. Compatible with all diesel fuels, including biodiesel blends, it’s a must-have for winter operation.
