The Armada’s 5.6-liter V8 typically uses 5W-30 full-synthetic engine oil, with an oil capacity around 6.5–7 quarts (approximately 6.2–6.6 liters) including the filter. In very cold climates, 0W-30 is an acceptable alternative if permitted by the model year and manual. Always confirm the exact specification for your vehicle in the owner’s manual or with a Nissan dealer.
Oil type and specifications
For most Armada models, Nissan recommends a 5W-30 full-synthetic engine oil that meets API SP or newer and ILSAC GF-5 or newer. Synthetic or synthetic-blend oils are both acceptable, but full synthetic is preferred for longer change intervals and better protection. Some markets or years may allow 0W-30 in cold climates; always consult your specific year’s manual to confirm the approved viscosity and specification.
Before you choose oil, keep these considerations in mind:
- 5W-30 full synthetic that meets API SP or newer and ILSAC GF-5 or newer
- 0W-30 full synthetic for cold-weather regions, if permitted by your manual
Conclusion: Use a reputable brand that meets the stated specs, and ensure the fill amount matches the engine’s capacity for your year and model. The typical change uses about 6.5–7 quarts with a new filter.
Capacity and service intervals
Oil capacity and recommended service intervals vary with oil type and driving conditions. The following guidelines apply to most 5.6L V8 Armada engines:
- Oil capacity: Approximately 6.5–7 quarts (6.2–6.6 liters) with filter
- Oil change interval with synthetic oil: roughly 7,500–10,000 miles (12,000–16,000 km) under normal conditions; severe-driving conditions may require 3,000–5,000 miles (4,800–8,000 km)
- Always follow the manufacturer’s maintenance schedule for your exact year and climate
Conclusion: Stick to the recommended viscosity and specification, monitor oil level regularly, and perform oil changes on the schedule that matches your driving conditions and warranty requirements.
Summary
In short, the Nissan Armada with a 5.6L V8 generally uses 5W-30 full-synthetic oil (API SP or newer, ILSAC GF-5 or newer), with an approximate capacity of 6.5–7 quarts per change. A 0W-30 option can be appropriate in very cold climates if your manual allows it. Always verify the exact oil specification for your model year and follow the recommended service intervals based on how you drive.
