15 MPG combined. That’s not great fuel economy. But the 2022 Chevrolet Silverado Cab Chassis 4WD 5.3L V8 isn’t about winning contests. It’s about getting serious work done, hauling heavy loads, and providing a strong foundation for upfits ranging from dump bodies to service beds. The fuel economy is a necessary trade-off for the capability this truck offers, and the people who buy it understand that.

City and highway performance

The EPA estimates place the Silverado Cab Chassis at 13 MPG in the city and 17 MPG on the highway. The city figure reflects the stop-and-go conditions and idling that are common on job sites, while the highway rating shows what’s possible when the truck is running unloaded or lightly loaded on the open road. The 5.3L V8, while a proven and reliable engine, is thirstier than the smaller turbocharged options available in some competitors. When paired with a 10-speed automatic transmission, it delivers smooth power, but it’s moving a heavy vehicle designed for brute force.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,900 for the 2022 Chevrolet Silverado Cab Chassis 4WD 5.3L V8. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices. Businesses using this truck for heavier loads, or in more demanding conditions, may see this figure increase noticeably. Fleet managers and owners should factor this cost into their operating budgets along with maintenance and other expenses.

Real-world expectations

While the EPA estimates provide a baseline, real-world fuel economy will vary depending on several factors like payload, towing, driving style, and terrain. Expect lower MPG when carrying heavy loads or towing trailers. Aggressive driving, such as rapid acceleration and hard braking, will also reduce fuel efficiency. Maintaining proper tire inflation and keeping up with scheduled maintenance are important for achieving the best possible fuel economy for this work truck.

How it compares

Compared to other cab chassis options, the Silverado sits in the middle of the pack. A Ford F-350 chassis cab with the 7.3L gas V8 will likely deliver similar, or perhaps slightly worse, fuel economy, while a Ram 5500 chassis cab with the Cummins diesel will likely achieve better mileage, around 16-18 MPG combined, but at a significant upfront cost increase. Considering all Chevrolet fuel economy data, the Silverado Cab Chassis prioritizes affordability and straightforward reliability over fuel efficiency. If you’re looking for efficiency within the Silverado line, you can review SILVERADO MPG across all years, but remember that those numbers are for consumer trucks, not the heavier-duty cab chassis model.

Tips to maximize efficiency

Minimize idling time whenever possible, especially on job sites where the truck may sit for extended periods. Even a few minutes of idling can significantly impact fuel consumption, so consider shutting the engine off when feasible to conserve fuel and reduce emissions.

Monitor tire pressure regularly. Underinflated tires create increased rolling resistance, which directly reduces fuel economy. Check your tires at least once a week and ensure they are inflated to the recommended pressure specified on the door placard.

Drive smoothly and avoid aggressive acceleration. The 5.3L V8 delivers plenty of power when you need it, but try to avoid rapid acceleration and maintain a steady speed. Anticipate traffic flow and brake gradually to conserve momentum and reduce unnecessary fuel consumption.

Consider the route. Planning your route to avoid congested areas and minimize stop-and-go traffic can improve fuel economy. Using GPS navigation to find the most efficient route can also help save fuel, especially in urban environments.

Reduce unnecessary weight. Carrying around extra weight in the truck bed or cab will decrease fuel economy. Remove any unnecessary tools, equipment, or materials to lighten the load and improve efficiency. Every pound counts when it comes to fuel consumption.
