Final answer:
To obtain an accurate oil level reading, check oil level within 30 minutes after running while oil is still hot (high marking) or prior to starting while oil is still cold (low marking). If more than 30 minutes has elapsed since running and engine oil is still hot, perform a cold check before checking oil level.
The correct answer to the question is b) 30 minutes, starting, hot, high, running, low, 15 minutes, cold, low.
Step-by-step explanation:
When the engine has been running, it’s important to wait for approximately 30 minutes before checking the oil level. This allows the oil to settle back into the oil pan and provides a more accurate reading. During this time, the oil will still be hot, and the high marking on the dipstick should be used as a reference point.
On the other hand, if the engine has been off and cold, it’s recommended to check the oil level before starting it. In this case, waiting for about 15 minutes allows the oil to settle back into the pan while it’s still cold. The low marking on the dipstick should be used as a reference point in this scenario.
If more than 30 minutes have passed since running and the engine oil is still hot, it’s advisable to perform a cold check before proceeding with checking the oil level. This ensures that an accurate reading is obtained even after an extended period of time since running.
In summary, following these specific timeframes and conditions when checking the oil level ensures that an accurate reading is obtained, allowing for proper maintenance of the vehicle’s engine.
The correct answer to the question is b) 30 minutes, starting, hot, high, running, low, 15 minutes, cold, low.
