What is the consequence of high oil temperature on turbine performance?

High oil temperature can lead to potential damage to oil system components in a turbine engine. Oil serves multiple critical functions, including lubrication and cooling. When the oil temperature exceeds acceptable limits, it can degrade the oil's properties, resulting in reduced lubrication effectiveness. This degradation can cause increased wear and tear on components, leading to potential failures in bearings, seals, and other vital parts of the oil system. Additionally, elevated temperatures can create conditions conducive to the formation of sludge or varnish, which can further impair system performance and integrity.

While other options suggest positive effects, high oil temperatures generally have detrimental consequences that compromise engine integrity and reliability. Therefore, understanding the importance of maintaining oil within specified temperature ranges is crucial for optimal turbine performance and longevity.
