Does the 2026 Chevrolet Silverado 4WD ZR2 (Sport/Off Road) need premium gas?
Fuel grade varies by trim — see the breakdown below.
| Trim (engine / transmission) | Fuel | MPG | Fuel/yr |
|---|---|---|---|
| 3.0L 6-cyl, Automatic 10-spd, 4WD | DIESEL | 21 | $3,700 |
The EPA records the fuel each version was tested on. Whether premium is strictly required or just recommended is an owner's-manual detail the EPA dataset doesn't include — so we don't guess it.
