Nissan X-Trail 2024 Owners Manual
10.6. Checking engine oil level

Park the vehicle on a level surface and apply the parking brake.
Run the engine until it reaches operating temperature.
Turn off the engine. Wait more than 10 minutes for the oil to drain back into the oil pan.
Remove the dipstick and wipe it clean. Reinsert it all the way.
Remove the dipstick again and check the oil level. It should be within the range (C). If the oil level is below (A), remove the oil filler cap and pour recommended oil through the opening. Do not overfill (B).
Recheck oil level with the dipstick.
It is normal to add some oil between oil maintenance intervals or during the running-in period, depending on the severity of operating conditions.

Oil level should be checked regularly. Operating the engine with an insufficient amount of oil can damage the engine, and such damage is not covered by the warranty.
