Final answer:
The correct statement is that turbine oils should contain balanced formulations for superior performance and property retention.
Step-by-step explanation:
The correct answer is A- turbine oils should contain balanced formulations with the right base oils and additives for the desired applications - the key to a superior turbine oil is property retention.
Turbine oils are used in the lubrication of gas and steam turbines. They need to have balanced formulations of base oils and additives to provide the desired performance and protection against wear, corrosion, and foaming. The key to a superior turbine oil is property retention, meaning that the oil should maintain its desired properties over a long period of time, even under high temperature and pressure conditions.
Option B is incorrect because hydroprocessed basestocks actually have higher solvency than conventional turbine stocks, not lower solvency. Hydroprocessed basestocks provide better oxidation stability, response to additives, and color stability in service due to the removal of impurities during the hydroprocessing process.
