Quick answer: the 2021–2025 Chevy Tahoe and Suburban 5.3L and 6.2L V8 take 8.0 qt (7.6 L) of oil with a filter change; the 5.3L uses SAE 0W-20. The 3.0L Duramax diesel takes 7.0 qt (6.6 L) of 0W-20 dexosD.
| Engine | Oil capacity (with filter) | Oil type | Specification |
|---|---|---|---|
| 5.3L V8 | 8.0 qt (7.6 L) | 0W-20 | dexos1 |
| 6.2L V8 | 8.0 qt (7.6 L) | See oil fill cap (2021–2024); 0W-20 (2025) | dexos1 |
| 3.0L Duramax diesel | 7.0 qt (6.6 L) | 0W-20 | dexosD |
6.2L owners: read the oil fill cap. The 2021–2024 manuals do not print one grade for the 6.2L; they say to use the viscosity shown on the engine oil fill cap. The 2025 manual lists SAE 0W-20 for the gas engines.

Recommended oil type
5.3L V8: SAE 0W-20 dexos1.
6.2L V8: the grade on the oil fill cap (2021–2024 manuals); SAE 0W-20 in the 2025 manual.
3.0L Duramax diesel: SAE 0W-20 meeting dexosD, 7.0 qt (6.6 L), per the Duramax 3.0L owner’s manual supplement.
GM requires oils that meet its dexos specification (dexos1 for gasoline engines, dexos2 or dexosD for diesels) and carry the dexos approved logo. ACDelco dexos oil is recommended. Do not add anything to the oil.
How to reset the oil life on the 2021–2025 Chevy Tahoe and Suburban
See also: Oil life reset by brand.
- Display the oil life percentage on the Driver Information Center (DIC).
- Press the thumbwheel on the steering wheel (or the trip odometer reset stem if there are no DIC controls) for several seconds.
- When the confirmation message displays, select YES. The oil life changes to 100%.
Reset only after an oil change; the system will not reset itself.
Oil change tips
- The V8 needs two 5-quart jugs; the diesel needs 7 quarts of dexosD oil.
- Add a little less than the full capacity, run the engine briefly, wait, and check the dipstick before topping up.
