Prestone Command is available in two different formulations:
• Extended Life provides 600,000-mile/12,000-hour CAT EC-1 protection for any diesel-powered heavy-duty engine. Its patented formula protects aluminum and all other engine metals against temperature extremes, rust, corrosion, scale and water-pump failure, and is compatible with any other heavy-duty antifreeze/coolant. A prediluted 50/50 formulation is available for convenient top-off applications.
• Extended Service is SCA pre-charged and provides advanced protection from freezing, overheating, cavitation erosion, corrosion, scale and foaming in any heavy-duty engine with need-release filter technology that is used in normal to severe duty cycles and extreme temperature conditions. A prediluted 50/50 antifreeze/coolant formulation and demineralized water dilution is available for convenient top-off applications.
Prestone Products Corporation is also launching its Prestone Command Diesel Exhaust Fluid (DEF), a liquid reducing agent that has been developed for use in all diesel engines that are equipped with a Selective Catalytic Reduction (SCR) system.
