About 6 quarts (roughly 5.7 liters) of engine oil are required for a full oil change on the 2015 GMC Yukon equipped with the 5.3-liter V8.
Here’s a clear explanation of the official specification, the recommended oil, and practical steps to ensure you fill to the correct level.
Official capacity and recommended oil
Oil capacity with and without the filter
The GM service information lists an oil capacity of 6 quarts (5.7 liters) when performing an oil and filter change with a new filter installed. If you drain oil and do not replace the filter, the capacity is about 5 quarts (4.7 liters). For best results, always replace the oil filter during an oil change.
Recommended oil type and grade
Use Dexos1 Gen 2 approved engine oil, typically 5W-30 for most climates. Check the owner’s manual or a GM dealer for your region, as viscosity recommendations can vary with ambient temperature and warranty terms.
Practical guidance for filling and checking
How to fill and verify the level
To fill and check the level: start with about 4–5 quarts, replace the oil filter, then add more in small increments while monitoring the dipstick. After topping up, run the engine briefly to circulate the oil, turn it off, wait a few minutes for the oil to settle, and recheck the level on a level surface. Top up to the full mark if needed, but avoid overfilling.
Summary
The 2015 GMC Yukon with the 5.3L V8 generally requires 6 quarts (5.7 liters) of engine oil for an oil and filter change when using a new filter, with about 5 quarts (4.7 liters) if the filter is not replaced.
