Rislone Hy-per Cool Super Coolant, No. HPC100, has a new, stronger formula that guards against overheating by directly targeting the surface tension of coolant, allowing it to deeply penetrate metal surfaces at critical areas inside the engine and radiator. Independent tests prove that Rislone Hy-per Cool Super Coolant reduces engine temperatures by up to 30 degrees F and lowers cylinder head temperatures up to 75 degrees F to enhance engine efficiency for better fuel economy, power, and performance.
