Question 4665
How should the engine oil level be checked?
- With the engine off and cold.
- With the engine running.
- With the engine warm.
Show answer and explanation
Correct answer: With the engine off and cold.
Check the level with the car on level ground and the engine off and cold. This lets the oil drain back into the oil pan so the dipstick shows how much is actually there. With the engine running or just shut off, some oil is still distributed throughout the engine, so the reading is lower. If your car's manufacturer specifies another method, follow it.
