    For street vehicles requiring freeze protection, add 1 bottle to 50/50 mix. For racing and high performance applications, add 2 bottles to straight water coolant for maximum temperature reduction. One bottle treats 12-20 quarts of a 50/50 water antifreeze mix. Two bottles are required for straight water coolant. For passenger cars, light trucks and SUV’s use every 30,000 miles. For racing applications use every race as needed. 

    With engine off and cool, shake bottle and pour into radiator. Start engine, turn heat on high and run for 10-15 minutes to circulate through entire cooling system. If straight water coolant is used, tap water or softened water is recommended. DO NOT use distilled water unless mixed with 50% antifreeze.
