Ground / Start Oil Pressure
*****Do not advance throttle above idle without positive (>0) indication of oil pressure. During cold weather, oil pressure may exceed limitations. This is normal indication as long as the oil pressure continues to decrease as engine oil warms. Do not exceed (5) minutes in military power with oil pressure above (55) PSI. If a sudden change of (10) PSI of greater in oil pressure indication occurs at any stabilized RPM, follow engine oil system malfunction procedures in Section III of the Dash-1.
