Prestone Products Corporation announced the availability of its new line of Prestone Command Diesel Exhaust Fluid (DEF) and its new Prestone Command Heavy-Duty Antifreeze/Coolant products.

Prestone Command DEF is a liquid-reducing agent that has been developed for use in all diesel engines that are equipped with a Selective Catalytic Reduction (SCR) system.

Prestone Command DEF is a colorless, odorless, non-toxic and non-flammable liquid solution consisting of 67.5% demineralized water and 32.5% high-quality automotive-grade urea. It meets all API and ISO 2224-1 manufacturing specifications.

DEF will corrode certain metals, such as aluminum, copper and brass, so it must be used and stored with dispensing equipment and tanks that are made of stainless steel or high-density polypropylene. Prestone Command DEF is available in 1- and 2.5-gallon (3.78- and 9.45-liter) containers, as well as 55-gallon (208.2 liter) drums and 330-gallon (1,249.19 liter) totes.

Prestone Products Corporation developed patented Prestone Command as an advanced antifreeze/coolant technology that 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.
