The 2017 GMC Yukon uses Dexos1 Gen 2 certified engine oil, with 0W-20 as the typical viscosity. If 0W-20 isn’t available, a Dexos1 Gen 2 approved 5W-30 can be used in certain conditions. Always verify the exact spec for your vehicle with the owner's manual or a GM dealer.
The Yukon offered two V8 engines in 2017—the 5.3L and the 6.2L—and both rely on Dexos1 Gen 2 oils. The precise viscosity can depend on engine variant, climate, and towing needs. This article outlines the official specification, acceptable alternatives, and practical steps to confirm the right oil for your Yukon.
Oil specification for the 2017 Yukon
Key facts about the oil your Yukon requires:
- Oil specification: Dexos1 Gen 2 certified engine oil.
- Standard viscosity: 0W-20 is commonly specified for most 2017 Yukons.
- Alternative viscosity: 5W-30 Dexos1 Gen 2 is acceptable if 0W-20 is not available or for certain operating conditions (e.g., towing or hot climates).
- Oil type: Oils labeled Dexos1 Gen 2 may be synthetic or synthetic-blend; ensure the oil you buy meets the Dexos1 Gen 2 spec.
For the exact requirement, check the vehicle’s oil fill cap and the owner's manual, or ask a GM dealer/service center to confirm for your VIN and engine choice.
Engine options in the 2017 Yukon
In 2017, the Yukon offered two V8 engines: the 5.3L V8 and the 6.2L V8. Both engines use Dexos1 Gen 2 oils, with 0W-20 as the typical viscosity and 5W-30 as a viable alternative under certain conditions.
How to confirm the right oil for your vehicle
Use these steps to verify the correct oil for your specific Yukon:
- Look for Dexos1 Gen 2 on the oil cap or in the owner's manual as the required specification.
- Confirm the recommended viscosity for your engine and climate (0W-20 is typically listed, with 5W-30 as an alternative under certain conditions).
- Ensure the oil you purchase is Dexos1 Gen 2 certified; not all oils labeled "Dexos" meet Gen 2 requirements.
- When in doubt, consult a GM dealer or trained technician who can reference your VIN and engine variant.
Following these checks helps you maintain warranty coverage and reliable performance in varied Yukon conditions.
Additional tips on oil choice and maintenance
In addition to the specification, consider these practical notes:
- Most 2017 Yukons use synthetic or synthetic-blend Dexos1 Gen 2 oils; check your manual for any model-specific guidance.
- Oil change intervals typically follow factory recommendations (often roughly every 7,500–10,000 miles under normal conditions or as shown by the vehicle’s oil life monitor).
- Using a high-quality synthetic Dexos1 Gen 2 oil can improve cold-start protection and high-temperature lubrication.
- Pair the oil with a new, compatible oil filter that matches Dexos1 Gen 2 specifications and engine size.
Always adhere to the manufacturer’s guidance and choose a Dexos1 Gen 2 certified oil appropriate for your climate and driving style to protect the engine and maintain warranty coverage.
Summary
The 2017 GMC Yukon typically requires Dexos1 Gen 2 certified engine oil, with 0W-20 as the standard viscosity and 5W-30 as a permitted alternate under certain conditions. Verify the exact spec for your Yukon by checking the owner's manual, the under-hood oil cap, or consulting a GM dealer, and choose a Dexos1 Gen 2 approved oil aligned with your climate and driving needs.
