What is an Organic Acid Technology (OAT) coolant and how is it different than conventional coolants?
Conventional antifreeze is formulated with inhibitors composed of neutralized inorganic acids, such as phosphates and silicates, to protect a cooling system against rust and corrosion. Over time, however, inorganic inhibitors deplete and may no longer provide maximum cooling system protection. This is why it is generally recommended that conventional coolants be changed every 2 years or 24,000 miles. In contrast, OAT coolants are formulated with neutralized organic acids to form a highly effective corrosion inhibitor system that provides maximum cooling system protection. Organic inhibitors do not deplete as quickly as the inorganic inhibitors used in conventional coolants. This is why properly formulated OAT coolants typically provide up to 150,000 miles or 5 years of cooling system protection between service intervals. The superior OAT formula in PEAK Global LifeTime uniquely provides a LifeTime of cooling system protection – for as long as you own your vehicle.
