The Acadia generally requires synthetic engine oil that meets GM’s Dexos1 Gen 2 specification, with viscosity chosen for your engine and climate (most commonly 0W-20 or 5W-30).
Because the Acadia has had several engine options across its generations, the exact grade and specification can vary by model year and engine. Always verify the precise oil type in your owner’s manual or with a GM dealer for your specific vehicle.
Dexos Gen 2 and the oil specification
What Dexos Gen 2 means for your Acadia
Dexos1 Gen 2 is GM’s current standard for gasoline engines in modern Cadillacs, Buicks, Chevrolets, and GMCs, including the Acadia. Oil that carries the Dexos1 Gen 2 certification is designed to protect engine tolerances and support warranty requirements.
Before you select oil, note that the required viscosity can differ by engine and climate. The most common grades you’ll see recommended are 0W-20 and 5W-30, but the exact grade for your vehicle should come from the owner’s manual or your dealer.
- Oil must be Dexos1 Gen 2 certified for use in gasoline engines that require GM-approved oil.
- Viscosity is typically 0W-20 or 5W-30, depending on the engine and climate. Confirm the exact grade for your model year and engine.
- Oil type can be synthetic or synthetic blend, as long as it meets Dexos1 Gen 2 specifications.
- Always check the vehicle’s oil fill cap and the owner's manual for the recommended grade and specification.
What to look for in the oil you buy:
Concluding: Using Dexos1 Gen 2-certified oil in the correct viscosity ensures proper lubrication, engine protection, and warranty compliance for your Acadia.
How to confirm the exact oil for your Acadia
To be sure you’re using the right oil, follow these steps before purchasing or changing oil:
- Consult the owner’s manual for the exact Dexos1 Gen 2 specification and viscosity recommended for your engine.

- If in doubt, call or visit a GM dealership or certified service center with your VIN to get the precise requirement for your vehicle’s year and engine.
Concluding: Rely on official sources—owner’s manual, under-hood markings, and dealership guidance—to ensure you use the correct oil for your Acadia.
Summary
In short, most GMC Acadias require synthetic oil that meets Dexos1 Gen 2 specifications, with common viscosities around 0W-20 or 5W-30 depending on the engine and climate. Always verify the exact grade and specification from the owner's manual or a GM dealership for your specific model year and engine configuration. Regular oil changes with the correct oil help maintain engine health and preserve warranty coverage.
