Final answer:
Turbine engines typically use a high-quality, synthetic oil known as turbine oil or jet engine oil.
Step-by-step explanation:
The type of oil used in a turbine engine oil system depends on the specific engine and its requirements. Turbine engines typically use a high-quality, synthetic oil known as turbine oil or jet engine oil. These oils are designed to withstand high temperatures and pressures, have excellent lubricating properties, and provide corrosion protection. They are often formulated to meet the specific requirements of turbine engines, such as low volatility to prevent excessive oil consumption and high thermal stability to withstand the extreme temperatures in the engine.
