LSI Chemical’s TotalArmor W7 is a winter blend diesel fuel aftermarket additive. It ensures complete operability in freezing temperatures. Engineered to provide consistent winter operability, this additive also increases cetane up to seven points for improved power, fuel economy, and cold starts. Formulated with cloud point and pour point depressants, anti-settling agents, detergents, and a powerful lubricity improver, TotalArmorW7 prevents gelling and icing by dispersing moisture in freezing temperatures, minimizing the size of wax crystals and preventing paraffin wax precipitation.
