Quick answer: the 2015–2020 Chevy Tahoe and Suburban (5.3L and 6.2L V8) take 8.0 qt (7.6 L) of SAE 0W-20 dexos1 oil with a filter change. The 2014 Tahoe and Suburban, the last of the previous generation, take 6.0 qt (5.7 L) of SAE 5W-30.
| Engine | Oil capacity (with filter) | Oil type | Specification |
|---|---|---|---|
| 5.3L / 6.2L V8 (2015–2020) | 8.0 qt (7.6 L) | 0W-20 | dexos1 |
| V8 (2014, previous generation) | 6.0 qt (5.7 L) | 5W-30 | dexos1 |
2014 and 2015 are different trucks. The redesigned 2015 Tahoe and Suburban switched to 0W-20 and 8.0 qt. The 2014 manual lists 6.0 qt of 5W-30 and warns against 10W-30, 10W-40 or 20W-50. Buy oil for your exact model year.

Recommended oil type
2015–2020: SAE 0W-20 meeting dexos1.
2014: SAE 5W-30 meeting dexos1; SAE 0W-30 may be used below -20°F (-29°C).
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 2014–2020 Chevy Tahoe and Suburban
See also: Oil life reset by brand.
- Display OIL LIFE REMAINING on the Driver Information Center (DIC). On trucks without DIC buttons, the vehicle must be in P (Park).
- Press and hold the select button, or the trip odometer reset stem on trucks without DIC buttons, for several seconds until the oil life changes to 100%.
Alternative from the same manuals: turn the ignition to ON/RUN with the engine off and fully press the accelerator pedal slowly three times within five seconds. Reset only after an oil change; the system will not reset itself.
Oil change tips
- The 2015–2020 V8 needs two 5-quart jugs.
- Add a little less than the full capacity, run the engine briefly, wait, and check the dipstick before topping up.
