The 2017 Buick Enclave uses 5W-30 synthetic oil that meets GM’s Dexos1 Gen 2 specification.
This specification applies to the 3.6-liter V6 engine used in most Enclave models from that year. Using the correct viscosity and Dexos1 Gen 2 standard helps protect the engine and maintain warranty compliance. Always verify with the owner's manual or a Buick dealer if you are unsure, and follow the recommended maintenance intervals.
Oil Type and Specifications
Key details you should know about the Enclave’s oil requirements before an oil change:
- Viscosity: 5W-30
- Specification: Dexos1 Gen 2 (GM’s standard for gasoline engines)
- Oil type: Full synthetic is recommended; many Dexos1 Gen 2 oils are synthetic or synthetic blends
Adhering to Dexos1 Gen 2 ensures compatibility with the engine and emissions system and supports warranty coverage when using a GM-approved oil.
Maintenance Tips
Practical tips to keep the oil in peak condition and the engine healthy:

Keeping to these practices helps maintain engine performance, fuel efficiency, and longevity over time.
Where to Confirm Details
Always refer to the vehicle’s owner’s manual or consult a Buick dealer if you have any questions about the correct oil specification, especially if your Enclave has an aftermarket engine or unique trim that may have different requirements.
