The amount of oil depends on which Xterra V6 you have. The 4.0-liter V6 uses about 5.5 quarts with a new oil filter, while the older 3.3-liter V6 takes roughly 4.6–4.8 quarts.
Engine options and official capacities
There were two V6 engines installed in Xterras over the years. Oil capacity figures below come from service manuals and owner guides and reflect typical installations. Actual capacity can vary slightly by model year, oil pan condition, and whether you’re changing the filter.
Below are the typical oil capacities by engine.
- VG33E 3.3L V6 (2000–2004 Xterra): about 4.6–4.8 quarts with a filter.
- VQ40DE 4.0L V6 (2005–2011 Xterra): about 5.4–5.5 quarts with a filter.
Note: The precise capacity can vary slightly with the oil pan volume and whether you are changing the filter. After an oil change, fill to the proper level on the dipstick, and top off as needed to reach the correct mark.
How to confirm which engine you have
To ensure you use the correct oil capacity for maintenance, confirm which V6 is in your Xterra with these checks.
- Check the engine code stamp on the engine block or valve cover. The 3.3L is VG33E, while the 4.0L is VQ40DE.
- Look at the model year and generation: 2000–2004 Xterras used the 3.3L; 2005–2011 used the 4.0L.
- Consult the owner’s manual or a VIN-based parts lookup if in doubt.
Knowing which engine you have will help you apply the correct fill figure and oil type for your vehicle.
Maintenance basics
When performing oil changes, follow standard practice: use the recommended oil viscosity, replace the filter, and verify the level with the dipstick after filling. For most climates, Nissan commonly recommends 5W-30 full-synthetic or synthetic-blend oil, but always confirm the specification for your year and region in the owner’s manual.
Summary
The Nissan Xterra’s oil capacity depends on the V6 engine: about 4.6–4.8 quarts for the 3.3L VG33E, and about 5.4–5.5 quarts for the 4.0L VQ40DE, with a new filter. Always verify with the dipstick and follow the engine-specific manual to ensure the correct fill. Regular oil changes help keep the V6 running smoothly.
