The amount of oil that the 2015 GMC Yukon needs iS8 quarts with a filter. The type that is recommended for the Yukon is 0W-20 Synthetic and the drain plug uses 18 ft/lbs of torque. Oil is used to help keep the engine clean and running smoothly and it will help the engine last longer. Oil is not meant to last forever, it tends to go bad after a while and needs to be changed every so often. In the Yukon it should be changed every 7,500 miles along with the filter. Some other maintenance on the vehicle You can do at the same time is rotating the tires and inspecting the brake pads and the engine air filter.
