Red Line has the next-generation of performance coolant that is compatible with factory BMW antifreeze. SuperCool is Nitrate, Phosphate, and Silicate-free and uses a proprietary OAT (Organic Acid Technology) formula for corrosion protection and prevent deposits. Instead of the BMW standard 2-3 year lifetime of factory coolant, Red Line recommends a service life of 5 years/150,000 miles. The advanced formula offers superior protection against cavitation and improve heat transfer compared to standard glycol-based coolant.
SuperCool includes the correct amount of Red Line Water Wetter pre-mixed. Water Wetter is specifically designed to reduce or eliminate bubbles or vapor barrier that form on hot metal surfaces such as the cylinder head. This helps avoid detonation/pinging and improve combustion.
1/2 gallon size (1.89 liters). Perfect for topping up or replacing a BMW expansion tank.
Also available as a Concentrate without the pre-mixed water.
