Capacity by engine option

Note: Some regions or specific models might have a 3.0L V6 option. Always refer to your owner's manual for the most accurate information.

Oil change interval

The oil change interval for your 2020 GMC Acadia is managed by the vehicle's Oil Life Monitoring (OLM) system. This system takes into account various factors such as engine revolutions, engine temperature, and driving conditions to determine when an oil change is due.

• Normal Duty: Typically, the OLM will recommend an oil change between 7,500 and 10,000 miles (12,000 to 16,000 km) or 12 months, whichever comes first. Always follow the prompts from your OLM system.
• Severe Duty: If your driving conditions involve frequent short trips, extreme temperatures, heavy towing, or extensive idling, the OLM system will likely recommend an oil change sooner, potentially as early as 3,000-5,000 miles (4,800 to 8,000 km). It is crucial not to exceed 12 months between oil changes, regardless of the mileage.

Drain plug torque

• 2.5L I4 Engine: 18 lb-ft (25 Nm)
• 3.6L V6 Engine: 18 lb-ft (25 Nm)

Always use a new drain plug crush washer during every oil change to ensure a proper seal and prevent leaks. The OEM crush washer is typically aluminum or rubber-coated metal.

How to change the oil

1. Gather Supplies: Ensure you have the correct oil, oil filter, drain pan, wrench for the drain plug, oil filter wrench, and a new crush washer.
2. Warm Up Engine (Optional but Recommended): Drive the vehicle for a few minutes to bring the oil to operating temperature, which helps it drain more easily. Be careful, as components will be hot.
3. Lift and Secure Vehicle: Safely lift the front of the vehicle using a jack and secure it with jack stands. Never work under a vehicle supported only by a jack.
4. Locate Drain Plug: Place your drain pan beneath the oil pan and locate the drain plug.
5. Drain Oil: Carefully remove the drain plug, allowing the old oil to drain completely into the pan. This may take several minutes.
6. Replace Drain Plug: Once all oil has drained, install the new crush washer on the drain plug and tighten it to the specified torque.
7. Remove Old Oil Filter: Place the drain pan under the oil filter housing (spin-on or cartridge, depending on engine), and remove the old oil filter using an oil filter wrench. Be prepared for additional oil to drain.
8. Prepare and Install New Filter: Apply a thin layer of new oil to the rubber gasket of the new spin-on filter. If it's a cartridge filter, ensure the new O-rings are installed correctly. Thread the new filter on by hand until snug, then tighten an additional 3/4 to 1 full turn (for spin-on) or to specific torque specifications (for cartridge, consult filter instructions).
9. Add New Oil: Remove the oil fill cap and carefully pour in the recommended amount and type of new engine oil.
10. Check Oil Level: Start the engine and let it run for a minute or two to circulate the oil. Turn off the engine, wait a few minutes, and then check the oil level using the dipstick. Add more oil if necessary until it reaches the "full" mark.
11. Check for Leaks: Inspect the drain plug and oil filter area for any signs of leaks.
12. Reset Oil Life Monitor: Follow the procedure in your owner's manual to reset the Oil Life Monitoring system.

Common issues / tips

• Oil Consumption: Some 2020 Acadia models, particularly with the 2.5L engine, may exhibit higher than average oil consumption. Regularly check your oil level between changes and top off as needed. Ignoring low oil levels can lead to severe engine damage.
• PCV Valve Issues: Problems with the Positive Crankcase Ventilation (PCV) system can contribute to oil consumption or even internal engine issues. If you notice excessive oil burning or smoke, have the PCV system inspected.
• Proper Oil Specification is Crucial: Using oil that does not meet the "dexos1 Gen2" (or newer) specification can lead to premature wear and may void your powertrain warranty. Always ensure the oil bears the official dexos1 logo on the bottle.
• Accessible Oil Filter: The oil filters on both engine options for the 2020 Acadia are relatively easy to access, making DIY oil changes straightforward.
