Stay Frosty Hi-Performance Coolant Gallon We formulate Stay Frosty Hi-Performance engine coolant for high-performance engines, which require additional protection from overheating and minimal freeze protection. To illustrate, our product contains both a specialized blend of heat transfer agents and propylene glycol. For that reason, it improves the coolant s ability to transfer heat away from high-temperature cylinder heads. Furthermore, tests show Stay Frosty Hi-Performance engine coolant lowers operating temperatures of engines by up to 14 degrees Fahrenheit compared to the conventional glycol-based coolant. This both increases the density of the air/fuel mix and allows ignition timing to be safely advanced without the threat of detonation.
