What is the oil pressure ground start limit?

• A. 182 (95 after 10 min)
• B. 150 (90 after 5 min)
• C. 200 (100 after 10 min)
• D. 165 (85 after 8 min)

Answer: (A)

Oil pressure during a ground start is watched in two stages: a high limit while the engine is being started, and a required minimum level once the engine has had time to warm up. The limit of 182 psi during start prevents over-pressurizing the lubrication system as oil is cold and the pump is working hard. After about 10 minutes of operation, the oil pressure should settle to a normal, steady level—about 95 psi—indicating the system is delivering oil properly at normal operating temperatures. This pairing matches how the oil system behaves: a high initial pressure with a safe ceiling during start, followed by a reliable, lower pressure once warm. The other options propose different maximums or wrong post-start values that don’t align with the established start and warm-up behavior.
