After motoring for 5 minutes, the recommended rest period is how many minutes?

• A. 10 minutes
• B. 15 minutes
• C. 20 minutes
• D. 5 minutes

Answer: (B)

After you run the engine on the ground, heat builds up in the various components and the lubrication system needs time to stabilize. The fifteen-minute cooldown lets temperatures fall and oil drain back to where it belongs, reducing thermal stress and making the next restart safer and smoother. Shorter cooldowns wouldn’t give enough time for cooling, while a longer break isn’t typically required for normal operations.
