What is the acceptable oil temperature range during Cessna 152 operations?

The acceptable oil temperature range during Cessna 152 operations is indeed between 100 to 220 degrees Fahrenheit. This range is critical for maintaining engine performance and ensuring the proper lubrication of engine components under various operating conditions.

Operating within this range helps prevent engine overheating, which can lead to severe damage and reduced efficiency. If the oil temperature falls below 100 degrees Fahrenheit, it implies that the oil may not be adequately providing lubrication, potentially leading to increased wear or engine problems. Conversely, temperatures exceeding 220 degrees can cause oil degradation and decrease its effectiveness, resulting in an inability to protect engine components effectively.

The other choices provided represent temperature ranges that are either too low, too high, or not suitable for operational conditions of the Cessna 152. Keeping the oil temperature within the specified limits is vital for the safety and performance of the aircraft, making the range of 100 to 220 degrees Fahrenheit the correct choice.
