What is the threshold for disabling engine oil pressure?

The threshold for disabling engine oil pressure is indeed less than 31 PSI. This value is critical because engine oil pressure is essential for the lubrication and cooling of the engine components. Maintaining adequate oil pressure prevents premature wear and potential catastrophic engine failure. If the oil pressure drops below this threshold, it indicates that the oil may not be circulating effectively throughout the engine, which can lead to overheating and serious damage.

In practice, reaching this threshold prompts operators and engineers to take action to either diagnose the cause of the low pressure or shut down the engine to prevent further damage. Understanding and adhering to this critical pressure limit is vital for the safety and operational integrity of the RB-M 45.
