Chevrolet Tahoe Oil Capacity & Oil Type
TL;DR
Newer EcoTec3 Tahoes (2015-present, 5.3L/6.2L) generally need 8 US qt (7.6 L) of 0W-20; older 2007-2014 5.3L Vortec models need about 6 US qt (5.7 L) of 5W-30.
Chevrolet Tahoe engine oil capacity by generation
The Tahoe has been built with several distinct V8 families, and oil capacity changed as GM moved from the Vortec engines to the direct-injected EcoTec3 line. Always match the figure to your specific engine code, not just the model year, since more than one engine can appear across overlapping years.
Where to confirm for your exact vehicle
- The engine oil specification sticker on the underside of the hood or near the oil filler cap
- Your owner's manual (Maintenance / Fluids and Lubricants section)
- The driver's door jamb placard (mainly tire pressure and GVWR, but often references the manual section for fluids)
- A GM dealer parts/service lookup by VIN, which ties the build to the exact engine code
Capacity and viscosity by engine
| Engine code / years | Capacity with filter (L / US qt) | Viscosity |
|---|---|---|
| 5.3L Vortec V8 (LC9/LY5/L94 family), 2007-2014 | 5.7 L / 6.0 qt | 5W-30 |
| 5.3L EcoTec3 V8 (L83), 2015-2020 | 7.6 L / 8.0 qt | 0W-20 (dexos1) |
| 6.2L EcoTec3 V8 (L86), 2015-2020 | 7.6 L / 8.0 qt | 0W-20 (dexos1) |
| 5.3L EcoTec3 V8 (L84), 2021-present | 7.6 L / 8.0 qt | 0W-20 (dexos1 Gen 2) |
| 6.2L EcoTec3 V8 (L87), 2021-present | 7.6 L / 8.0 qt | 0W-20 (dexos1 Gen 2) |
Why some references quote a different L83 figure
For the 2015-2020 5.3L L83 engine, a few older references still list 8.5 US qt (8.0 L) with filter. GM revised the service fill down to 8.0 US qt (7.6 L) during the 2014-2015 model years, and that revised figure is what appears in later owner's manuals and in current service information. Use 8.0 US qt (7.6 L) and confirm on the dipstick after the fill.
General guidance
Always add oil gradually and check the dipstick rather than pouring the full rated amount at once, since a new filter, oil cooler, or prior partial drain can change how much the engine actually needs to reach the correct level.

Frequently asked questions
Does the 5.3L Tahoe always take the same amount of oil?
No. The 2007-2014 5.3L Vortec V8 (LC9/LY5/L94 family) takes about 6.0 US qt (5.7 L) of 5W-30, while the redesigned 2015-2020 5.3L EcoTec3 L83 takes 8.0 US qt (7.6 L) of 0W-20, and the 2021-present 5.3L L84 takes 8.0 US qt (7.6 L) of 0W-20. Check your engine code, not just the model year.
What oil viscosity does a modern Tahoe need?
EcoTec3 V8s built from 2015 onward (5.3L L83/L84 and 6.2L L86/L87) specify 0W-20 full synthetic meeting GM dexos1 (Gen 2 on 2021-present models). Older 2007-2014 5.3L Vortec engines specify 5W-30 instead.
How much oil does the 6.2L Tahoe take?
Both the 2015-2020 6.2L L86 and the 2021-present 6.2L L87 use approximately 8.0 US qt (7.6 L) of 0W-20 synthetic oil with a new filter, based on multiple independent service references.
Where is the definitive oil capacity for my specific Tahoe?
The most reliable source is your owner's manual or the underhood oil specification label, cross-checked against your VIN at a GM dealer parts desk, since it identifies the exact engine code (stamped on the engine block and listed in the VIN) rather than relying on the model year alone.
