Engines run cooler by 15°C (30°F) : Improves thermal exchange and engine cooling system efficiency. Cooling system optimal protection against corrosion. Recommended for magnesium, aluminium alloys cases, cast iron, copper, brass and bronze systems. Water pump protection, avoid cavitation Anti-corrosion properties that remain while high temperature and ageing. Low corrosion inhibitors consumption. Seals, rubber pipes, and plastics parts friendly.
