21 MPG combined isn’t going to win any hypermiling awards, but the 2022 Chevrolet Silverado 1500 with mud-terrain tires, four-wheel drive, and the 3.0L Duramax diesel is for a specific buyer. This Silverado configuration appeals to those who prioritize off-road capability and strong towing rather than outright fuel efficiency. These truck owners value the diesel’s torque and the enhanced traction of the mud-terrain tires far more than squeezing every last mile from a gallon of fuel.

City and highway performance

The EPA estimates this particular Silverado configuration achieves 20 MPG in the city and 23 MPG on the highway. These numbers reflect the compromise in choosing a truck with aggressive off-road tires and a drivetrain designed to handle demanding tasks. The mud-terrain tires, while excellent in challenging conditions, introduce significant rolling resistance on paved roads, impacting fuel consumption, especially in stop-and-go city driving. The four-wheel-drive system, though not constantly engaged, adds weight and complexity, further contributing to the MPG figures. The 10-speed automatic transmission helps optimize fuel consumption at various speeds, but it can only do so much against the inherent inefficiencies of this truck’s specific design.

Annual fuel cost

The EPA estimates the annual fuel cost for this 2022 Chevrolet Silverado configuration at $2,650. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s important to remember this is just an estimate; your actual fuel costs may vary depending on your driving habits, the type of driving you do (more city or highway), and local fuel prices. However, the $2,650 figure provides a useful benchmark for understanding the potential cost of ownership.

Real-world expectations

While the EPA provides a standardized estimate, real-world fuel economy can vary significantly. Owners of this Silverado configuration should expect to see figures slightly below the EPA estimates, especially if they frequently engage the four-wheel-drive system or spend a considerable amount of time driving in demanding conditions. Hauling heavy loads or towing will also have a noticeable impact on fuel consumption. Factors such as driving style, tire inflation, and vehicle maintenance will also influence real-world MPG. Knowing the limitations of the vehicle is key.

How it compares

Compared to its competitors, the 2022 Silverado with the 3.0L diesel and mud-terrain tires occupies a specific niche. A comparable Ford F-150 with the 3.5L EcoBoost V6 and four-wheel drive typically achieves around 19 MPG combined, while a Ram 1500 with the 3.0L EcoDiesel and four-wheel drive is rated at around 24 MPG combined. A Toyota Tundra with its standard V6 Turbo engine is lucky to get 20 MPG combined in any configuration. These variations highlight the trade-offs in choosing different powertrains and configurations. The Ram’s slightly better fuel economy might appeal to some, but others might prioritize the Silverado’s styling or specific features.

Tips to maximize efficiency

Despite the Silverado’s inherent limitations, there are steps owners can take to improve fuel economy. Avoid aggressive acceleration and braking, as these habits waste fuel. Gentle and consistent driving will always yield better results.

Regularly check and maintain proper tire inflation. Underinflated tires increase rolling resistance, negatively impacting fuel economy. Refer to the sticker on your driver’s side doorjamb for the recommended tire pressure.

Minimize idling time. If you’re stopped for more than a minute, turn off the engine. Modern vehicles are designed to restart quickly and efficiently, and avoiding prolonged idling can save fuel.

When possible, avoid using four-wheel drive on paved roads. Four-wheel drive increases fuel consumption, so only engage it when necessary in off-road or slippery conditions.
