The 2018 GMC Acadia requires 0w-20 or 5w-20 oil for optimal performance. It's crucial to use top-quality oil to ensure your engine runs smoothly. Neglecting the oil can lead to engine issues, such as knocking sounds, poor gas mileage, and a strong burning smell. It is essential to address these signs promptly to prevent potential engine damage. Regular oil changes, ideally every 5,000 to 10,000 miles, are recommended to maintain the engine's health and prevent any problems from arising in the future.
In 2018, the GMC Acadia comes in different versions with either a 2.5 liter or a 3.6 liter engine. The 2.5 liter models, including the SL, SLT-1, SLE-1, and SLE-2, require 0w-20 or 5w-20 oil. On the other hand, the 3.6 liter engine models - the Acadia SLT-1, SLT-2, and Denali - need 0w-30 or 5w-30 oil.
