Lucas Oil 10640 Details

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.

Our unique coolant additive formula prevents deposits that can cause overheating, and has been proven to reduce coolant temperatures up to 20°F.
Lower cylinder head temperatures means advanced ignition and more horsepower.

  • Lower cylinder head temps
  • Allow advanced ignition, timing and more horsepower
  • Reduce operating temperatures by up to 20°
  • Prevents corrosion, electrolytes and deposits that cause leaks, overheating, and cooling system failures

Learn more about how cooling systems work with proper coolant mixture and additives by reading our tech article.Cooling System Principles.

Application

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.
