Chevrolet Tahoe Oil Change Interval & Oil Type
When to change the oil on a 2021-2024 (5.3L / 6.2L V8 / 3.0L Duramax) Chevrolet Tahoe, and what oil it takes.
| Oil change interval | Oil-Life Monitor, ~7,500 mi (diesel has its own monitor) |
|---|---|
| Engine / oil | 5.3L or 6.2L V8 (AFM/DFM) or 3.0L Duramax diesel; dexos1 0W-20; 10-speed auto |
| Oil filter | Replace with every oil change |
Chevrolet Tahoe note: The V8s use AFM/DFM cylinder deactivation — many owners change oil strictly on time (and some delete AFM) to reduce lifter issues. Towing a big SUV means the severe trans interval.
