Not For Use In Cooling Systems That Use Proprietary or Manufacturer Specific Coolants. Lucas Super Coolant has been scientifically formulated to provide the ultimate protection in automotive and racing cooling systems. It protects the entire system from rust, corrosion and electrolysis including aluminum and has been proven to reduce coolant temperatures up to 20 degrees F. Our unique formula prevents deposits that can cause overheating. Lower cylinder head temperatures means advanced ignition time and more horsepower. 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 SUVs use every 30,000 miles. For racing applications use every race as needed.
