The 2015 Chevy Traverse uses Dexos1 Gen 2-certified motor oil with a viscosity of 5W-30 for most driving conditions. Oils meeting this specification can be synthetic, synthetic-blend, or conventional, but must carry the Dexos1 Gen 2 certification. Always check the owner's manual for climate-specific guidance.
Oil specification and viscosity
Understanding the official requirement helps ensure engine protection and warranty compliance. The 3.6L V6 engines common in the 2015 Traverse call for Dexos1 Gen 2 oil with a viscosity of 5W-30 in typical conditions. This means you should look for a motor oil labeled Dexos1 Gen 2 and rated 5W-30, regardless of brand, and you can choose synthetic, synthetic-blend, or conventional formulations that meet that specification.
Dexos1 Gen 2 certification
Dexos1 Gen 2 is GM’s standard for motor oil compatibility with its engines. Oils that carry this certification are tested to meet GM’s performance and emissions requirements, supporting engine longevity and warranty terms. When shopping, always verify the packaging shows “Dexos1 Gen 2” and the viscosity listed is 5W-30.
To help you shop, note the key criteria you should look for on the oil container:
- Dexos1 Gen 2 certification clearly printed on the label
- Viscosity listed as 5W-30
- Formulation type: synthetic, synthetic-blend, or conventional oil that meets Dexos1 Gen 2
In practice, selecting a reputable brand that explicitly states Dexos1 Gen 2 5W-30 ensures compatibility with the 2015 Traverse and complies with GM guidelines. If you’re ever in doubt, confirm with your owner's manual or a Chevrolet dealer.
Practical guidance for buying and changing oil
Before you buy or perform an oil change, follow these steps to ensure you’re using the correct oil and maintaining the vehicle properly.
