The Infiniti QX80 with the 5.6-liter V8 generally requires about 6 quarts of engine oil for a full change with filter. This is the standard capacity for the VK56-series engines used in the QX80 family.
Oil capacity can vary slightly by model year and engine variant, and it's important to confirm the exact figure from the owner's manual or service data for your specific vehicle. This article outlines the typical capacity, notes on year-by-year differences, and practical guidance for planning an oil change.
Official oil capacity for the QX80
For most QX80s, the engine oil capacity is commonly cited as approximately 6 quarts when performing a complete oil change with a new filter. This figure assumes you replace the filter, which is standard practice during a full oil change.
When planning an oil service, it's prudent to have a little extra on hand in case of spillage or if your vehicle's automatic oil-level system requires more headroom. Always confirm the exact specification for your year and engine variant in the owner's manual or Infiniti service data.
- Typical engine oil capacity (with new filter) for the QX80’s 5.6L V8 is about 6 quarts.
In practice, you should prepare around 6 quarts of oil and a new oil filter for a standard full-change on most QX80s; check your dipstick and the service label to confirm the final volume after draining and filtering.
Engine variants and model-year notes
The QX80 uses the VK56-series 5.6-liter V8. Modern QX80s (and many QX56 predecessors) generally list oil capacity near 6 quarts with filter, but exact figures can vary by year, oil type, and whether you replace the filter.
VK56VD (model years from around 2014 onward)
Most contemporary QX80s with the VK56VD 5.6L engine maintain an oil capacity close to 6 quarts with filter. Always verify the precise specification for your year in the owner's manual or a current service sheet.
VK56DE (earlier QX56/QX80 variants)
Earlier VK56DE-equipped models are generally similar in capacity, typically around 6 quarts with filter; exact numbers should be checked in the service manual for the specific year and engine code.
Practical oil-change notes
When planning an oil change, keep these guidelines in mind to ensure a proper fill and reliable lubrication.
- Have approximately 6 quarts of oil on hand and a new filter ready for a standard full-change.
- Verify the exact capacity and recommended viscosity from your owner’s manual, the label under the hood, or Infiniti’s official service data.
- Consider driving conditions and climate; severe service may affect oil-change intervals and the amount needed if the engine drains more than expected.
In all cases, the goal is to ensure the engine is filled to the proper level after a drain-and-fill, with the dipstick indicating a correct reading and the oil pressure stable upon startup.
Summary
For most Infiniti QX80 models, the engine oil capacity is about 6 quarts with a new filter. While this figure covers the majority of VK56VD and VK56DE-powered QX80s, always verify the exact specification for your year and engine variant in the owner's manual or official Infiniti service data. Plan for around 6 quarts, and adjust if your vehicle requires a different amount due to year or engine code.
