What is the mpg on a 2013 Chevy Silverado 3500 diesel?
Typically, the Duramax-powered Silverado 3500HD gets roughly 15–16 mpg in city driving and about 21–23 mpg on the highway, with the exact figures depending on drivetrain and body configuration.
For buyers and readers seeking clarity, fuel economy on a 2013 Silverado 3500HD varies by cab style, bed length, drivetrain (2WD vs. 4WD), and wheel setup. Real-world mileage is often lower when towing or carrying heavy payloads, and EPA estimates are a starting point rather than a guarantee.
EPA estimates by configuration
Because the 2013 Silverado 3500HD was offered in several configurations, the official EPA numbers differ. The following ranges cover common setups you might encounter on a used 2013 model:
- 2WD Regular Cab Long Bed: about 16 mpg city / 23 mpg highway; combined around 19 mpg.
- 2WD Crew Cab Short Bed: about 15 mpg city / 22 mpg highway; combined around 18 mpg.
- 4WD Crew Cab Short Bed: about 14–15 mpg city / 20–21 mpg highway; combined around 17–18 mpg.
- 4WD Dual Rear Wheel (Dually) Crew Cab Long Bed: about 14–15 mpg city / 20 mpg highway; combined around 17–18 mpg.
Conclusion: The numbers above reflect EPA estimates and can vary by model year, regional testing, and vehicle condition. Actual mileage will vary with payload, towing, terrain, and driving habits.
Real-world mileage and factors that affect mpg
In everyday use, diesel Silverado 3500s often see lower mileage when towing trailers, hauling heavy payloads, or navigating hilly terrain. Highway cruising at steady speeds can push the mpg toward the upper end of the EPA highway estimates, while city conditions and frequent starts can depress numbers. Owners frequently report real-world ranges roughly between 12 and 18 mpg under typical heavy-duty use, with higher figures possible on unladen highway driving.
Tips for maximizing mpg (brief)
To optimize fuel economy, maintain proper tire pressure, keep the engine well-tuned, reduce aerodynamic drag (remove roof racks when not in use), and plan efficient routes to minimize stop-and-go driving. For heavy towing, consider trailer braking and weight distribution to improve efficiency and safety.
Summary
The 2013 Chevy Silverado 3500 diesel’s fuel economy, as estimated by the EPA, generally falls in the mid-teens in city driving and low-to-mid-20s on the highway, with exact figures depending on cab, bed, drivetrain, and wheel configuration. Real-world mileage varies widely, especially with towing and payload, but understanding the configuration helps set realistic expectations.
