What can be a consequence of over-oiling an aircraft engine?

Oil foaming and potential engine damage
Improved lubrication efficiency
Enhanced engine power
Lower engine temperature

The correct answer is: Oil foaming and potential engine damage

Over-oiling an aircraft engine can lead to oil foaming, which occurs when excessive oil creates air bubbles as it is agitated within the engine. This foaming reduces the oil's ability to lubricate effectively, as the air mixed with the oil can prevent proper contact with engine components. Consequently, the lack of effective lubrication can lead to increased friction and heat, potentially causing severe engine damage, such as worn bearings or even engine failure. In contrast, the other options suggest outcomes that are generally not associated with over-oiling. Improved lubrication efficiency, enhanced engine power, and lower engine temperatures are typically expected outcomes when an engine is properly maintained and oiled within the recommended levels. However, over-oiling disrupts this balance and leads to detrimental effects, underscoring the importance of adhering to the manufacturer's specifications for oil levels in aircraft engines.
