About this item Helps prevent DEF crystallization - NuDEF Extreme Weather is specially formulated to combat the formation of harmful crystals in sub-zero temperatures and under int ense heat. By actively inhibiting the crystallization process, it ensures that your DEF remains fluid and ready to do its job—even when external conditions are at their most challenging. Lowers freezing point of DEF - Unlike ordinary DEF additives, NuDEF Extreme Weather actively reduces the temperature at which DEF begins to freeze. This extra margin of protection helps prevent the DEF tank, lines, and pump from freezing solid on extremely cold days, so your system stays operational without costly downtime or repairs. Protects SCR system, DEF tank, pump & injector from scorching summer heat to bitter winter cold, the sensitive components in your Selective Catalytic Reduction (SCR) system are constantly under stress. NuDEF Extreme Weather forms a protective barrier and lubricating layer that defends the DEF tank, pump, and injector against both temperature-related wear and tear and crystal-induced clogs. Treats up to 25 gallons of DEF- One bottle of NuDEF Extreme Weather goes a long way. Each dose treats 2.5 gallons of DEF, providing up to 25 gallons’ worth of advanced temperature protection in every bottle. This makes it a convenient, cost-effective way to ensure reliable performance—even in the most extreme weather conditions. Show more
