Which answer gives the correct range of the normal operating oil pressure for Cessna 152 in pounds per square inch?

The range of normal operating oil pressure for a Cessna 152 is indeed between 60 and 90 pounds per square inch (psi). This operating range is crucial for maintaining the engine's health and ensuring it operates efficiently. Oil pressure is vital as it lubricates the engine components, reducing friction and wear while also helping to cool the engine.

If the oil pressure falls below the normal operating range, it may indicate insufficient lubrication, which can lead to increased wear and potential engine failure due to overheating or seize. Conversely, oil pressure readings that exceed this range may suggest possible issues such as a clogged oil filter or overheating, which can also damage the engine. Therefore, maintaining the oil pressure within the specified 60 to 90 psi range is essential for safe flight operations and the longevity of the aircraft's engine. Understanding and monitoring these parameters helps ensure pilots can react to potential mechanical issues promptly.
