Maximum continuous oil temperature

• A. 140 C
• B. 135 C
• C. 145 C
• D. 150 C

Answer: (A)

Maximum continuous oil temperature is the highest oil temperature you can sustain during normal, ongoing operation without risking engine damage. Oil serves as both lubricant and heat remover; as oil gets hotter, it becomes less viscous and protection can degrade, increasing wear and the chance of oxidation or seal issues. For the P-8A’s engines, the continuous limit is 140 C, meaning you can operate up to that temperature indefinitely with proper cooling and lubrication.

Temperatures above this limit are not suitable for continuous operation and are generally allowed only for brief transients or specific procedures to manage a temporary condition. The other values (lower or higher) either aren’t the sustained limit or exceed it, so they don’t represent the maximum you can hold continuously.
