Here is the standard oil capacity you should plan for when performing a routine oil change on a 2008 QX56.
- 7 quarts (approximately 6.6 liters) of engine oil, including the oil filter.

Context, tips, and best practices
Engine and maintenance context
The VK56DE V8 powering the 2008 QX56 is designed for a relatively generous oil capacity to maintain proper lubrication under heavy use. The 7-quart figure is the standard reference for a full drain and filter replacement, ensuring the engine receives adequate protection between changes.
Oil type and change considerations
For most climates, Infiniti/Nissan typically recommends synthetic 5W-30 full-synthetic oil for the VK56DE, though always follow the exact specification in your owner’s manual. When you change the oil, replace the filter, wipe the drain plug area clean, and reuse a new washer if applicable. After adding oil, wait a few minutes, then check the dipstick and top up as needed to reach the correct level.
Oil-change practical steps
Before performing an oil change, assemble the right tools, materials, and safety precautions. The following steps outline a typical process, with attention to the 7-quart capacity requirement.
- Warm up the engine slightly, then turn off and secure the vehicle. Place it on a level surface and engage the parking brake.
- Drain the old oil completely, remove and replace the oil filter with a new one, and reinstall the drain plug with an appropriate torque.
- Pour in 6 to 7 quarts of the recommended oil, checking the level with the dipstick after a short settling period.
- Replace the oil fill cap, start the engine, and run for a few minutes to circulate oil. Recheck for leaks, then recheck the dipstick and add if necessary.
Following these steps helps ensure you’ve delivered the correct total oil volume and proper lubrication for the engine’s service interval.
Summary
The 2008 Infiniti QX56 typically requires about 7 quarts (roughly 6.6 liters) of engine oil for a full change with a new filter. Always confirm with the owner's manual or service data for your exact vehicle, and use the recommended oil grade (commonly 5W-30) to maintain optimal engine protection. Plan accordingly and monitor the oil level after the change to ensure accurate topping.
