Understanding the 2015 GMC Acadia oil capacity is fundamental for maintaining the longevity and performance of this family-oriented three-row SUV. The engine, a reliable 3.6-liter V6, requires the correct volume of lubricant to ensure proper circulation, cooling, and reduction of friction within its moving parts. Adding the precise amount of oil during a change prevents potential damage caused by under-filling and avoids the negative consequences associated with overfilling.
2015 GMC Acadia Engine Specifications
The 2015 model year offered the Acadia with a single engine option, which simplified the maintenance process for owners. This was the 3.6-liter direct-injection V6, producing 310 horsepower and 271 pound-feet of torque. This powerplant was mated to a six-speed automatic transmission and was designed to run on regular unleaded gasoline. Knowing the specific engine type is crucial because oil capacity varies significantly between a four-cylinder and a V6 configuration.
Oil Capacity and Filter Details
For the 3.6-liter V6 engine found in the 2015 GMC Acadia, the total oil capacity is 6.4 quarts. This figure represents the amount of oil required to fill the engine from a cold start after the drain plug has been removed and reinstalled. It is important to distinguish this total capacity from the amount added after an oil change, which is usually lower because the oil filter holds a portion of the total volume. The recommended filter is typically a standard size filter that holds approximately 0.5 quarts, meaning you would add roughly 5.9 quarts of fresh oil into the engine sump before starting the vehicle.
Recommended Oil Type and Viscosity
To ensure optimal performance, GMC specifies the use of 5W-30 or 5W-20 viscosity oil for this engine. The "5W" indicates the oil's cold-flow properties, allowing it to circulate quickly during startup in cold weather, while the "30" or "20" refers to the oil's thickness at operating temperature. General Motors often recommends dexos1™ certification, which guarantees the oil meets stringent GM engine cleanliness and performance standards. Using the correct viscosity protects the hydraulic lash adjusters and maintains the fuel efficiency that the Acadia’s buyers appreciate.
Step-by-Step Oil Change Procedure
When performing an oil change on a 2015 Acadia, having the correct tools and materials ensures a clean and efficient process. You will need a socket wrench set, a new oil filter, a drain pan, and, of course, the 6.4 quarts of fresh oil. The procedure involves lifting the vehicle safely, locating the drain plug underneath the oil pan, and allowing the old oil to drain completely. Once the drain plug is secured, the new filter is applied with a small amount of fresh oil to the gasket, and the fresh oil is poured into the filler cap located under the hood. Always check the dipstick after running the engine to verify the level is within the proper range.
