The 2015 GMC Acadia with the 3.6 L V6 typically uses about 6 quarts of engine oil when performing an oil change with a new filter.
In practice, you may be closer to 5 quarts if you don’t replace the oil filter, and the exact amount can vary slightly depending on engine variant and draining efficiency. Always confirm by checking the dipstick after adding oil and follow the owner's manual for the correct oil type and capacity.
