| Engine | Oil capacity (with filter) | Oil type | Specification |
|---|---|---|---|
| 2.7L turbo | 6.0 qt (5.7 L) | 5W-30 | dexos1 |
| 4.3L V6 (2019–2021) | 6.0 qt (5.7 L) | 5W-30 | dexos1 |
| 5.3L V8 | 8.0 qt (7.6 L) | 0W-20 | dexos1 |
| 6.2L V8 | 8.0 qt (7.6 L) | 0W-20 (2019–20, 2025); see oil fill cap (2021–24) | dexos1 |
| 3.0L Duramax diesel | 7.0 qt (6.6 L) | 0W-20 | dexosD |
6.2L Denali and AT4 owners: check the oil fill cap. The 2021–2024 Sierra manuals say to use the viscosity printed on the 6.2L fill cap instead of giving one grade. The 2019–2020 and 2025 manuals list 0W-20.
