These figures assume a standard full-synthetic oil change with a new filter. If you skip replacing the filter, you’ll need less oil.
- 5.6 quarts (5.3 liters) with filter change
- 5.0 quarts (4.7 liters) without changing the filter
For most maintenance sessions, plan for roughly 5.5–5.6 quarts to ensure the level sits within the recommended range after refill.
Recommended oil and filtration
To meet Nissan specifications and maximize engine protection, use a full-synthetic 5W-30 oil that meets API SN or ILSAC GF-5, and install a compatible Nissan-approved oil filter.
Note: The following guidelines help ensure you choose the right oil and filter. Do not rely on a single source; always verify with the owner's manual or a Nissan service advisor.
- Viscosity: 5W-30 (climate and manual guidance may allow alternatives; follow the manual)
- Capacity: 5.6 quarts (5.3 liters) with filter; 5.0 quarts (4.7 liters) without filter
- Filter: OEM Nissan oil filter or equivalent meeting Nissan’s specifications
Always check the exact specification in your owner’s manual, as regional variations may apply and Nissan may update recommendations.

How to ensure accuracy on your refill
After completing the oil change, start the engine and let it run briefly before checking the level on the dipstick. Add oil in small increments if the level is below the recommended mark, and recheck to avoid overfilling. If in doubt, consult a qualified technician.
