Silverado MPG & Mileage
Shopping for a full-size truck around Chickasha usually comes with one big question: what’s this going to cost at the pump? At John Holt Chevrolet, we hear it every week, and Chevy Silverado MPG 2026 numbers are better than many folks expect. Here’s what the Silverado 1500 actually gets, which setups stretch a tank the farthest, and why so many Oklahoma drivers keep coming back to it.
What MPG Does the 2026 Silverado 1500 Get?
The 2026 Chevrolet Silverado 1500 is EPA-rated between 17 and 25 MPG combined. The 3.0L Duramax diesel with 2WD sits at the top, while the gas V8s land around 17 MPG combined. Most standard TurboMax trucks fall within the 19-20 MPG combined range.
Here’s what many shoppers miss: your Chevy Silverado mileage depends more on the engine than the trim badge. There are four engines to choose from: the 2.7L TurboMax four-cylinder makes 310 horsepower and 430 lb-ft of torque. The 5.3L V8 makes 355 horsepower, the 6.2L V8 makes 420 horsepower, and the 3.0L Duramax turbo-diesel pairs 305 horsepower with 495 lb-ft of torque.
Here’s where each setup lands, according to EPA estimates:
| Engine | Drivetrain | City MPG | Highway MPG | Combined MPG |
|---|---|---|---|---|
| 2.7L TurboMax I-4 | 2WD | 18 | 21 | 20 |
| 2.7L TurboMax I-4 | 4WD | 17 | 21 | 19 |
| 5.3L EcoTec3 V8 | 2WD | 16 | 20 | 17 |
| 5.3L EcoTec3 V8 | 4WD | 15 | 19 | 17 |
| 6.2L EcoTec3 V8 | 4WD | 15 | 20 | 17 |
| 3.0L Duramax Turbo-Diesel | 2WD | 23 | 28 | 25 |
| 3.0L Duramax Turbo-Diesel | 4WD | 22 | 25 | 23 |
EPA-estimated figures for the 2026 Silverado 1500. Off-road trims such as Trail Boss and ZR2 carry their own, typically lower ratings. Actual mileage will vary.
How Do Silverado Fuel Economy in the City and on the Highway Compare?
Every Silverado 1500 does better on the highway than around town, and the gap is widest with the Duramax. A 2WD diesel goes from 23 MPG in the city to 28 MPG on the highway, a five-MPG jump.
That matters around here. If your week includes runs up the H.E. Bailey Turnpike toward Oklahoma City or down to Lawton, you’re spending time at steady highway speeds, right where the Silverado is most efficient. Comparing Silverado fuel economy in the city and highway also shows why the diesel appeals to high-mileage commuters.
In town, the Silverado gets help from Automatic Stop/Start. The engine shuts off at a full stop and restarts when you lift off the brake. It’s small at one red light, but it adds up over a month of errands.
What About Silverado FWD vs. AWD Gas Mileage?
The Silverado 1500 isn’t offered with front-wheel or all-wheel drive. It comes as 2WD, which powers the rear wheels, or 4WD, and 2WD is the more efficient of the two.
When people search for Silverado FWD vs. AWD gas mileage, they’re usually comparing 2WD versus 4WD. The difference is modest. With the TurboMax, 4WD costs about one MPG in the city and none on the highway. With the diesel, it’s about two MPG combined, thanks to extra weight and drivetrain hardware. If your truck spends most of its time on pavement, 2WD saves a little fuel. If you deal with muddy lease roads or a slick boat ramp, 4WD is usually worth the trade.
Why Do Drivers Love the Silverado 1500?
Drivers love the Silverado because it doesn’t force a choice between capability and reasonable running costs. The TurboMax gives you strong low-end torque in an efficient package, the V8s deliver the classic big-engine feel, and the Duramax combines serious pulling power with the best mileage in the lineup.

The 3.0L Duramax turbo-diesel with 2WD is the most efficient, with EPA estimates of 23 city, 28 highway, and 25 combined MPG.

Depending on configuration, the 2026 Silverado EV is EPA-rated up to 70 MPGe combined, with up to 493 miles of estimated range.
