The 2018 GMC Acadia runs on synthetic oil. The 2.5L 4-cylinder engine takes either SAE 5W-20 or 0W-20. For the FWD model, you need 5 quarts of oil, and for the AWD model, you'll need 6 quarts. The 3.6L V6 engine requires SAE 5W-30 and holds 6 quarts. It is recommended that you change your oil every 7,500 miles or once a year, whichever comes first. Regular oil changes can prolong your engine's life, improve gas mileage, and enhance performance. By sticking to a routine maintenance schedule, you can prevent engine issues caused by particles and sludge buildup. Neglecting oil changes can lead to severe engine problems as the oil becomes thinner, abrasive, and wears down critical engine components over time.
