🔍 Key Concepts

• Gas turbine engine (GTE) operating temperatures and how they compare to diesel/steam plants • Differences between petroleum-based and synthetic lubricating oils • Effects of high temperature on oil stability, viscosity, and seals

💭 Think About

• Think about what conditions the lubricating oil experiences inside a gas turbine compared to a slow-speed diesel—especially temperature and speed of rotating parts. • Ask yourself which property of the oil is MOST critical for surviving in a very hot, high‑speed environment: metal compatibility, viscosity, seal compatibility, or thermal stability? • Consider which option describes a fundamental limitation of petroleum oil chemistry, not just a design choice.

✅ Before You Answer

• Verify which option deals with high-temperature stability of the oil itself, rather than just matching specific components. • Check whether viscosity differences alone would completely rule out the use of petroleum oils in GTEs, or if viscosity can be formulated and adjusted. • Make sure you distinguish between problems that can be engineered around (like different seals or metals) and an inherent limit of petroleum oil performance under GTE temperatures.
