The LSI Chemical TotalArmorW7 is a winter blend diesel fuel aftermarket additive formulated to ensure complete operability in freezing temperatures while also improving other important characteristics of diesel fuel. With cloud point and pour point depressants, detergents, and a lubricity improver, TotalArmorW7 prevents gelling and icing and disperses moisture to ensure full operation even in freezing temperatures. It minimizes the size of wax crystals and prevents paraffin wax precipitation to allow fuel to travel through the fuel filter and remain operable. The fuel additive complies with all federal low sulfur content requirements for use in diesel motor vehicles and non-road engines.
