Important: Millers Oils Extra Cool is a Coolant ADDITIVE and DOES NOT contain any antifreeze.
Millers Oils Extra Cool is a corrosion inhibitor and coolant enhancer concentrate, designed to be added to coolant to help maintain flow and reduce deposit formation in radiators, and reduce coolant temperature by up to 15°C. Provides powerful corrosion protection for all metals found in engines. Can be used in motorsport applications where antifreeze is disallowed.
Dilute with water in the ratio 1 part Extra Cool to 50 parts water [2% solution] for corrosion inhibition of vehicle cooling systems and deposit reduction.
Note: Antifreeze is often based on ethylene or propylene glycol, which are insoluble in oil. Internal coolant leaks may cause damage to highly stressed bearings.
