Q: In what formulations is Prestone Command™ Heavy Duty Antifreeze/Coolant available?
A: It is available in two formulations: Prestone Command™ Extended Life Heavy Duty Antifreeze/Coolant (Red) and Prestone Command Extended Service Heavy Duty Antifreeze/Coolant (Purple).
Q: What differentiates Prestone Command™ Heavy Duty Extended Life Antifreeze/Coolant?
A: The Extended Life formulation, which is denoted by its red color and labeling, 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
Q: What differentiates Prestone Command™ Heavy Duty Extended Service Antifreeze/Coolant?
A: The Extended Service Interval formulation, which features purple coloring and labeling, is SCA pre-charged and provides advanced protection from freezing, overheating, cavitation erosion, corrosion, scale and foaming in any heavy duty engine with or without Need-Release® filter technology that is used in normal to severe duty cycles and extreme temperature conditions.
Q: Are Prestone Command™ Heavy Duty Antifreeze/Coolants available in 50/50 Prediluted formulations?
A: Yes. The Extended Life 50/50 Prediluted formulation has a concentrated blend of premium long-lasting inhibitors and is intended for use with any heavy duty antifreeze/coolant in any diesel-powered commercial vehicle or stationary engine with aluminum or other engine metals. The Extended Service Interval 50/50 Prediluted formulation is a blend of antifreeze/coolant and demineralized water designed for use in any heavy duty engines that are used in normal to severe duty cycles and extreme temperature conditions.
Q: Can Prestone Command™ Extended Life and Extended Service Antifreeze/Coolants be mixed?
A: Yes, both are compatible with any other heavy duty antifreeze/coolant.
Q: Why should I use Extended Life antifreeze/coolants?
A: Extended Life antifreeze/coolants are recommended by nearly all heavy duty engine OEMs to help protect the sophisticated coolant systems typical on modern-day heavy duty vehicles. Extended life antifreeze/coolants eliminate routine testing and help keep vehicles in operation longer, all of which help reduce operating costs and maximizes uptime.
Q: Besides CAT EC-1, what other product performance specifications and requirements does Prestone Command™ Extended Life Heavy Duty Antifreeze/Coolant meet or exceed?
A: Prestone Command™ Extended Life Heavy Duty Antifreeze/Coolant meets or exceeds performance requirements of all major engine manufacturers, along with the following specifications: TMC RP-329, ASTM D-6210, ASTM D-4985, ASTM D-3306, SAE 1941.
Q: What performance specifications and requirements does Prestone Command™ Extended Service Heavy Duty Antifreeze/Coolant meet or exceed?
A: It meets or exceeds the performance requirements of all major engine manufacturers, along with the following specifications: TMC RP-329, ASTM D-6210, ASTM D-4985, ASTM D-3306 and SAE 1941.
Q: In what dosage should Prestone Command™ Extended Service Heavy Duty Antifreeze/Coolant be used?
A: For optimum protection against freezing or boil-over, a 50/50 mix of Prestone Command™ Extended Service Heavy Duty Antifreeze/Coolant and tap water should be used. Concentration levels should not fall below 40% or exceed 65% by volume.
Q: What is the shelf life of Prestone Command™ Antifreeze/Coolant?
A: In its original sealed container, Prestone Command™ Antifreeze/Coolants have a shelf life of many years. Even if the product has been opened but not diluted with water, it maintains a shelf life of many years.
Q: What Makes the "Patented" Prestone Command Technology different than other Antifreeze Coolants?
A: The patented technologically advanced technology is based upon a concentrated blend of premium long-lasting inhibitors designed to provide up to 600,000 miles/12,000 hours* of protection against temperature extremes, rust, corrosion, scale and premature water pump failure. When used as directed, Prestone Command™ Heavy Duty ELC may be added to the antifreeze/coolant of any heavy duty commercial or stationary engine. It provides a silicate, phosphate and borate-free technology for long lasting inhibition and corrosion protection and protects aluminum and all other engine metals.

Q: Why Can 1 Million Mile AFC Change Interval Claims Be Harmful To Your Engine?
Despite their eye-catching nature, recent claims of 1 million mile AFC change intervals aren't based on any new science or coolant technology, they just imply that existing coolants now have the ability to offer as much as 67% more miles of engine and coolant-system protection. Therefore, operators of heavy duty vehicles shouldn't take at face value 1 million mile claims that could end up doing nothing more than putting their engines at risk. They should also be aware that while heavy duty engines have become increasingly more sophisticated in recent years, most coolant technologies have remained the same since the days when a 200,000-mile change interval was considered groundbreaking. With all that said, heavy duty vehicle operators must first and foremost realize that reliable engine performance – no matter the number of miles that have been driven – depends on proper maintenance, which includes the use of patented Prestone Command™ Extended Life Coolant.
Q: Why Are Recommended Antifreeze/Coolant Change Intervals Important?
A: Today's heavy duty diesel engines are finely tuned instruments designed to go the extra mile … provided they are properly treated and maintained. Proper maintenance also applies to the sophisticated cooling systems, which require antifreeze/coolants specially designed for heavy duty engines. Therefore, it is imperative that drivers and fleet managers adhere to the engine manufacturer's recommended change intervals to maximize the engine's performance and decrease the chance of failure. It's also important to maintain the correct coolant level by topping off regularly with a compatible coolant to ensure your engine remains at the correct temperature … and is fully protected!
