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°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 SUV’s use every 30,000 miles. For racing applications use every race as needed.
I bought this for my '92 Mustang with 302 motor, as it tends to run hot during the summer. I switched from 30% antifreeze to straight water plus 2 bottles of Lucas Supercoolant. Wouldn't you knwo it, it ran 18 degrees cooler! So I'm buying 2 more bottles for my truck. Will see what it does. Very pleased with the results. Thanks Lucas for this great new product.
