About

Oil cooling is commonly used to cool high-performance motorcycle engines that are not liquid-cooled. Typically, the cylinder barrel remains air-cooled in the traditional motorcycle fashion, but the cylinder head benefits from additional cooling. But if the engine is a racing engine that is always producing huge amounts of heat, water or liquid cooling may be preferable. Oil has a higher boiling point than water, so it can be used to cool items at a temperature of 100 °C or higher. However, pressurised water-cooling may also exceed 100 °C. Cooling water can be corrosive to the engine and must contain a Corrosion inhibitor/rust-inhibitor, whereas oil naturally helps to prevent corrosion.
