What is the primary reason for using low volatile synthetic oil in turbine engines?

Using low volatile synthetic oil in turbine engines primarily enhances heat range efficiency and helps prevent evaporation at high altitudes. Synthetic oils are designed to withstand extreme temperatures and have a higher thermal stability compared to conventional oils. This quality allows them to retain their lubricating properties even under the challenging conditions of turbine operation, including the high temperatures and pressures present within the engine.

Additionally, low volatility means that these oils tend to evaporate less readily, which is particularly crucial at higher altitudes where pressure and temperature fluctuations can be more significant. By minimizing evaporation, the oil maintains its lubrication effectiveness, ensuring that engine components receive the necessary protection from wear and tear.

While cost and availability, lubrication in cold conditions, and engine performance are important factors in selecting oil for turbine engines, they do not specifically encapsulate the primary function and advantage of low volatile synthetic oils as effectively as the properties related to heat range efficiency and evaporation prevention do.
