24 MPG combined is an impressively high figure for a full-size, four-wheel-drive truck like the 2024 Chevrolet Silverado with the 3.0L Duramax diesel. This isn’t a compact crossover designed for saving gas, it’s a workhorse capable of hauling and towing significant loads. The Silverado configuration achieves mileage figures that rival some midsize SUVs, which shows the efficiency advancements Chevrolet has made. This Silverado appeals to buyers who need the capability of a full-size truck but are also mindful of fuel costs, whether they’re covering long distances for work or using it as a daily driver.

City and highway performance

The EPA estimates the 2024 Chevrolet Silverado 4WD 3.0L diesel at 23 MPG in the city and 27 MPG on the highway. The city rating is particularly noteworthy. Full-size trucks often suffer in stop-and-go traffic, but the Duramax diesel’s low-end torque and the smooth-shifting 10-speed automatic transmission help to reduce fuel consumption. The highway figure is even more appealing, making this Silverado a comfortable and relatively economical choice for long road trips or highway-heavy commutes. The broad torque band means less downshifting and more relaxed cruising, factors that contribute to achieving those impressive highway numbers.

Annual fuel cost

The EPA estimates that the annual fuel cost for the 2024 Chevrolet Silverado 4WD 3.0L diesel will be $2,300. This figure is based on driving 15,000 miles per year and using national average fuel prices. Of course, your actual fuel costs will vary depending on your driving habits, location, and the prevailing price of diesel fuel in your area. However, this $2,300 benchmark provides a good reference point when comparing the Silverado’s fuel expenses against those of other vehicles. This is an important consideration for many truck buyers who are increasingly conscious of the long-term ownership costs associated with larger vehicles.

Real-world expectations

While the EPA estimates offer a standardized comparison, real-world fuel economy can vary. Drivers who frequently tow heavy loads or spend a significant amount of time off-road will likely see lower numbers. Conversely, those who primarily use their Silverado for commuting or highway driving may find that they exceed the EPA’s estimates. Factors such as driving style, tire pressure, and even the use of accessories like roof racks can also influence fuel consumption. The 3.0L Duramax is known for delivering consistently good fuel economy, but realistic expectations are essential to managing fuel costs.

How it compares

Against its competitors, the 2024 Chevrolet Silverado 4WD 3.0L diesel stacks up very favorably in terms of fuel economy. Consider the Ford F-150, while the hybrid version achieves slightly better city MPG numbers, its highway MPG is comparable, and the diesel Silverado offers a blend of efficiency and capability. Comparing to the Ram 1500, its V6 eTorque configuration delivers similar MPG figures, but the Silverado’s inline-six diesel is arguably a more refined and durable engine choice for many users. See SILVERADO MPG across all years. Even considering the Toyota Tundra, which is known for its reliability, it cannot match the Silverado diesel’s fuel efficiency, especially in highway driving. The raw MPG number, and the type of work the truck can perform while delivering it, make it a strong pick in its segment. All Chevrolet fuel economy data can be viewed here.

Tips to maximize efficiency

Gentle acceleration and smooth braking are key to maximizing fuel economy in any vehicle, but especially in a truck. The Duramax diesel produces ample torque at low RPMs, so avoid excessive throttle inputs. Anticipate traffic flow and coast whenever possible to minimize the need for hard braking.

Maintaining proper tire pressure is another simple yet effective way to improve fuel efficiency. Check your tires regularly and inflate them to the recommended pressure level, which can be found on the driver’s side doorjamb or in the owner’s manual. Underinflated tires create more rolling resistance, which reduces fuel economy.

Minimize idling. Idling consumes fuel without covering any distance, so avoid letting the engine run unnecessarily. If you’re stopped for more than a minute, it’s generally more efficient to turn off the engine. The Silverado’s start/stop system can help with this, automatically shutting off the engine at traffic lights and restarting it when you release the brake pedal.

Reduce aerodynamic drag. Removing unnecessary items from the truck bed and avoiding the installation of accessories that increase wind resistance, such as bulky roof racks, can help to improve fuel efficiency, especially at highway speeds. Consider a tonneau cover for the bed to further streamline airflow over the truck.

Consider using cruise control. While it can maintain a consistent speed, it may not always be the most efficient option in hilly terrain. Pay attention to the road ahead and adjust your speed manually to minimize unnecessary downshifting and fuel consumption. Let the engine braking assist on downhill stretches rather than constantly applying the brakes.
