Approximately 5 quarts (4.7 liters) of engine oil, including a new oil filter, is needed for a full change on the 2019 Acadia with the 3.6 L V6.
In detail, the 2019 Acadia’s 3.6 L V6 requires Dexos1 Gen 2 0W-20 engine oil and uses about 5.0 quarts with a new filter. This specification comes from the vehicle’s owner manual and GM service data. Oil-change intervals are guided by GM’s Oil Life System (OLM), which adjusts recommended service timing based on driving conditions.
Oil Capacity and Specifications
This section summarizes the official capacity and the recommended oil specification for the 3.6 L engine in the 2019 Acadia.
Key figures at a glance
- Engine oil capacity (with filter): 5.0 quarts (4.7 liters).
- Recommended oil type: Dexos1 Gen 2 0W-20 synthetic (or synthetic blend as specified by the manual).
- Note: This capacity assumes a new oil filter is installed; actual quantity may vary slightly if a different filter is used or if the drain is not fully complete.
For a full oil change, plan to have about 5 quarts of oil plus a new filter. After adding oil, recheck the level with the dipstick to ensure it sits within the normal range.
Maintenance and Oil Change Intervals
The Acadia uses GM’s Oil Life System to estimate when an oil change is due. Under normal driving conditions with Dexos1 Gen 2 0W-20, intervals commonly fall in the 7,500–10,000 mile range, but more frequent changes may be advised for severe service, frequent short trips, or extreme climates.
General steps for checking and planning oil changes:
- Park on level ground and let the engine cool for at least 10 minutes before checking the oil level.
- Check the engine oil level with the dipstick; the level should lie between the ADD and FULL marks when the engine is cold.
- If the level is low, add 0W-20 Dexos1 Gen 2 oil in small increments (about 1/4 quart at a time) and recheck to avoid overfilling.
- When performing a full oil change, replace the oil filter with a new one.
- Dispose of used oil and the old filter at an authorized recycling facility or service center.
Conclusion: Rely on the GM Oil Life System and manufacturer recommendations to determine exact intervals, and maintain proper oil levels and filter changes to protect the engine.
Summary
The 2019 GMC Acadia with the 3.6 L engine requires about 5 quarts (4.7 liters) of Dexos1 Gen 2 0W-20 oil when changing the oil with a new filter. Oil-change intervals are guided by GM’s Oil Life System and typically range from roughly 7,500 to 10,000 miles under normal conditions, with more frequent changes possible in severe service. Always refer to the owner’s manual and follow your vehicle’s OLM prompts for precise guidance, and ensure proper disposal of used oil.
