How should you check the engine oil level?
Answer and explanation
Correct answer: A. With the engine off and the car on level ground, using the dipstick
- Step 1: A reading is accurate only once the oil has drained back into the sump. Step 2. Switch off, wait a moment on level ground, then read the dipstick. Answer: With the engine off and the car on level ground, using the dipstick. Why not the others: A running engine, a slope, or a warning light gives no valid level reading.
