Minimum Oil Pressure is?

• A. 13 psi
• B. 12 psi
• C. 14 psi
• D. 15 psi

Answer: (A)

Oil pressure shows how well the engine is being lubricated. The minimum limit is the lowest pressure at which the engine can operate without risking bearing and moving-part damage. For the P-8A’s engine, that minimum acceptable value is 13 psi. This threshold is set to ensure sufficient lubrication across different speeds and temperatures; oil pressure naturally varies with RPM and oil temperature, but it must not fall below this point. If it does, it signals a potentially unsafe lubrication condition and requires following the abnormal procedures to protect the engine, rather than continuing normal operation. The other numbers aren’t the mandated minimum; they would represent higher thresholds or readings under different circumstances, but 13 psi is the defined minimum you must not exceed downward.
