For anyone considering a 2024 Chevrolet Silverado equipped with mud-terrain tires, four-wheel drive, and the 3.0L Duramax diesel, 22 MPG combined is likely a low priority. This isn’t a Prius. It’s a work-capable truck built for venturing far beyond the pavement’s edge, so fuel consumption is a consideration.

City and highway performance

The EPA estimates the Silverado’s fuel economy at 21 MPG in the city and 23 MPG on the highway. These numbers reflect the trade-offs of a truck designed for off-road adventures. The mud-terrain tires provide superior grip on loose surfaces, but create more rolling resistance on pavement. Fuel efficiency is therefore reduced, particularly around town, where stop-and-go driving constantly demands torque to get rolling from a standstill. Highway driving is generally more efficient, but still suffers from the aerodynamic challenges of a large truck profile and the added weight of its four-wheel-drive components.

Annual fuel cost

The EPA estimates the annual fuel cost for this specific Silverado configuration at $2,550. This figure is based on driving 15,000 miles per year, with an assumed even split between city and highway driving, and using national average fuel prices. Your fuel costs will vary depending on local fuel prices, driving habits, and the proportion of city versus highway miles driven. Drivers who frequently tow or spend the majority of their time off-road will almost certainly exceed this annual fuel cost estimate.

Real-world expectations

Don’t expect to achieve the EPA numbers. Owners of this particular Silverado configuration are likely more concerned with getting to remote trailheads than maximizing MPG. Fuel economy will dip considerably when actively using four-wheel drive or carrying heavy loads. Towing will further reduce efficiency. A realistic expectation for daily driving is likely a range between 18-22 MPG, depending on driving style and terrain. However, unlike the gasoline V8 options, you can expect consistent fuel efficiency even while towing.

How it compares

Compared with its gas-powered rivals, the Duramax-equipped Silverado has a fuel economy advantage. A comparable Silverado 1500 with the 5.3L V8 engine and four-wheel drive manages around 17 MPG combined. The Ford F-150 with the 3.5L EcoBoost V6 and four-wheel drive lands in a similar range, at approximately 18 MPG combined. The RAM 1500 with the 5.7L HEMI V8 and eTorque mild hybrid system nets around 19 MPG combined. Given the small MPG difference and the torque benefit of the Duramax, buyers prioritizing work capability will find the diesel’s slightly higher upfront cost balanced by its long-term fuel savings.

Tips to maximize efficiency

Proper tire inflation is critical, especially with mud-terrain tires. Regularly check and maintain the recommended tire pressure to reduce rolling resistance and improve fuel economy. Even a few PSI makes a difference.

Avoid aggressive acceleration and hard braking. Gradual acceleration and smooth braking maximize fuel efficiency, especially since this truck is heavier than its 2WD equivalents. Anticipate traffic flow and maintain a steady speed.

Minimize idling. The Duramax diesel, like all diesels, consumes fuel even when stationary. Shut off the engine during extended stops. Modern diesels have quick and easy starting systems, so restarts don’t waste time.

Service the engine frequently. Regular maintenance, including oil changes and filter replacements, ensures the engine operates efficiently. A well-maintained engine consumes less fuel and lasts longer.

Keep the truck bed unloaded. Hauling unnecessary weight decreases fuel efficiency. Remove any cargo that isn’t essential for your daily driving, especially around town.
