Dexos1 Gen 2 5W-30 synthetic motor oil.
Oil type and grade
The 2017 Yukon, whether powered by the 5.3L EcoTec3 V8 or the available 6.2L EcoTec3 V8, is designed to run on Dexos1 Gen 2 approved 5W-30 synthetic motor oil. This specification helps with engine protection, fuel efficiency, and emissions system compatibility. Always verify the exact viscosity and specification on the oil fill cap or in the owner's manual, especially in extreme temperatures.
Before you look at a shopping list or changes, here are the key details to keep in mind when selecting oil for your Yukon:
- Dexos1 Gen 2 approval: Use oil that meets GM's Dexos1 Gen 2 specification to ensure compatibility with the engine and warranties.
- Viscosity: 5W-30 is the standard grade for most climates; consult the manual for any climate-specific recommendations.
- Formulation: Fully synthetic motor oil is preferred for these engines; conventional oil is not typically recommended.
- Capacity considerations: Oil capacity varies by engine configuration (roughly around 8 quarts for the 5.3L and more for the 6.2L, depending on filter and setup); verify exact capacity in the manual or under the hood sticker.
In practice, choose a high-quality Dexos1 Gen 2 5W-30 synthetic oil and follow GM’s service intervals as outlined in the owner's manual. This helps ensure optimal lubrication, protection, and performance.
Engine options and capacity considerations
The 2017 Yukon offered two V8 engines. While both use Dexos1 Gen 2 5W-30 synthetic oil, the amount of oil required can vary with engine choice and configuration. Always confirm the exact capacity for your specific model and trim level in the owner's manual or service documentation.
- 5.3L EcoTec3 V8: Typically requires about 8 quarts of oil with a filter when performing a full oil change, using Dexos1 Gen 2 5W-30 synthetic oil.
- 6.2L EcoTec3 V8: Requires a similar Dexos1 Gen 2 5W-30 synthetic oil, with a slightly higher capacity overall depending on the particular configuration and filter used.
If your Yukon is equipped with a different drivetrain or a special edition, always double-check the exact capacity and specification in the owner's manual or on the service label under the hood.
Summary
For the 2017 Yukon, the recommended oil is Dexos1 Gen 2 5W-30 synthetic motor oil. Verify the exact viscosity and capacity for your engine variant in the owner's manual or on the fill cap, and follow GM’s maintenance intervals to ensure optimal engine protection and performance.
