What type of oil is recommended for high-speed and high-temperature applications?

The recommended oil for high-speed and high-temperature applications is synthetic oil. Synthetic oils are specially formulated to withstand extreme conditions, providing excellent thermal stability and lower volatility compared to mineral oils. They tend to maintain their viscosity at higher temperatures, which is crucial in high-performance environments like gas turbines. Synthetic oils also offer superior lubrication properties, reducing wear and tear on mechanical components, which is essential for maintaining operational efficiency and longevity in high-stress conditions.

In contrast, mineral oils may not perform as well under such rigorous conditions due to their lower thermal stability and greater susceptibility to breakdown. Vegetable oils, while biodegradable and sometimes used in specific applications, generally do not handle high temperatures and conditions as well as synthetic oils. Lubricating oils can include a wide range of products and are not indicative of either the thermal resistance or the performance characteristics found in synthetic oils.
