The EPA estimates the 2022 Chevrolet Silverado Cab Chassis 2WD with the 5.3L V8 gets 17 MPG combined, a figure that’s realistically secondary to the truck’s core mission. This isn’t a lifestyle pickup. It’s a workhorse, purchased primarily by businesses and upfitters who prioritize capability, payload, and a clean slate for customization. Fuel economy, while certainly a factor, is less important than its potential as a tow truck, ambulance, flatbed hauler, or countless other specialized applications.

City and highway performance

The EPA estimates for the 2022 Silverado Cab Chassis 2WD with the 5.3L V8 are 15 MPG in the city and 18 MPG on the highway. These figures reflect the inherent challenges of moving a heavy-duty vehicle, even in its bare-bones cab chassis form. Stop-and-go city driving naturally taxes the engine, while highway speeds, even with the 10-speed automatic transmission working to optimize efficiency, demand a steady stream of fuel to maintain momentum and overcome wind resistance. Remember that these numbers are based on standardized testing procedures and can vary significantly depending on driving style, load, and terrain.

The 10-speed automatic is a definite improvement over older transmissions in this class, offering smoother shifts and more opportunities to keep the engine in its most efficient range.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2022 Chevrolet Silverado Cab Chassis 2WD 5.3L 8-cyl to be $2,600. This calculation is based on driving 15,000 miles per year and using national average fuel prices. This figure provides a standardized benchmark for comparing fuel costs across different vehicles.

Business owners considering this truck should factor in their anticipated mileage and local fuel prices for a more accurate estimate, because commercial vehicles often log far more than the average 15,000 annual miles.

Real-world expectations

While the EPA numbers offer a guideline, real-world MPG for the Silverado Cab Chassis can fluctuate substantially. The final configuration of the truck, whether it’s outfitted as a dump truck, service body, or something else entirely, will dramatically influence its aerodynamics and weight, directly impacting fuel consumption. Payload is another critical factor. Hauling heavy loads, which this truck is designed to do, will inevitably decrease fuel economy.

Aggressive driving habits, such as rapid acceleration and hard braking, will also contribute to lower MPG. Therefore, drivers should anticipate that the actual MPG may fall slightly below the EPA estimates, particularly in demanding work environments.

How it compares

Compared to other heavy-duty work trucks, the 2022 Chevrolet Silverado Cab Chassis 2WD 5.3L V8 occupies a typical spot in its class, where fuel economy is rarely a highlight. A comparable Ford F-350 Chassis Cab with its standard 6.2L V8 is rated at a similar 15 MPG combined. The Ram 3500 Chassis Cab with the 6.4L Hemi V8 also returns comparable numbers in real-world use, although official EPA estimates are not published for heavy-duty chassis cabs. The primary reason these trucks are purchased isn’t for their efficiency, but rather for their reliable construction, payload capacity, and adaptability to various commercial applications.

Tips to maximize efficiency

Regular maintenance is critical for optimizing fuel economy in a work truck like the Silverado Cab Chassis. Ensure that the tires are properly inflated to the recommended pressure, as underinflated tires increase rolling resistance and decrease MPG. Keep the engine properly tuned and replace air filters regularly to ensure optimal combustion and performance. A well-maintained engine operates more efficiently and consumes less fuel.

Driving habits have a significant impact on fuel consumption. Avoid aggressive acceleration and hard braking. Gradual acceleration allows the engine to work more efficiently, and anticipating traffic conditions can minimize the need for sudden stops. Maintaining a steady speed on the highway, rather than constantly speeding up and slowing down, can also improve fuel economy.

Minimize unnecessary weight. The heavier the load, the more fuel the truck will consume. Remove any unnecessary tools or equipment from the truck bed when they are not needed. Even small reductions in weight can contribute to noticeable improvements in fuel economy over time.

Use the truck’s technology features to enhance fuel efficiency. The 10-speed automatic transmission is designed to keep the engine in its optimal operating range. Engage cruise control on the highway to maintain a consistent speed and minimize unnecessary acceleration. Pay attention to the driver information display, which often provides real-time fuel economy data and driving tips.
