After engine shutdown, how long must you wait before checking the oil level?

• A. 1 Minute
• B. 5 Minutes
• C. 10 Minutes
• D. 15 Minutes

Answer: (B)

Oil level readings after shutdown require time for the oil to settle back into the reservoir. If you check immediately, oil still in the lines and crankcase can make the dipstick read lower than the actual amount. Waiting five minutes lets the oil drain back to the sump so the dipstick shows an accurate level. Then check on level ground with the engine off, and ensure the reading is within the marked range. Five minutes is the prescribed wait time.
