Lentokoneöljy

Lentokoneöljy, also known as aviation oil, is a specialized lubricant used in internal combustion engines of aircraft. Unlike automotive oils, lentokoneöljy is designed to meet the stringent demands of aviation, which include extreme temperature variations, high altitudes, and the need for exceptional reliability and safety.

There are two primary types of lentokoneöljy: mineral-based and synthetic. Mineral-based oils are derived from refined crude oil and have been the standard for many years, particularly in piston engines. They are known for their good performance in a wide range of operating conditions. Synthetic oils, on the other hand, are engineered in laboratories to offer superior performance characteristics. These can include better thermal stability, improved viscosity control across a wider temperature range, and enhanced resistance to oxidation and deposit formation. Synthetic oils are often used in more modern or demanding aviation applications.

Key properties of lentokoneöljy include its viscosity, pour point, flash point, and oxidation stability. Viscosity determines the oil's resistance to flow and is critical for maintaining proper lubrication at different temperatures. A low pour point ensures the oil remains fluid at cold start-up temperatures, while a high flash point indicates resistance to ignition. Oxidation stability is vital for preventing oil degradation and sludge formation during prolonged operation.

The choice of lentokoneöljy depends on the specific aircraft engine type, manufacturer recommendations, and operating environment. Regular oil analysis is often performed to monitor the condition of the oil and the engine's internal components, helping to ensure safe and reliable flight operations.
