How many miles per gallon does a Chevy 3500 HD get?
The short answer is: fuel economy on the Chevrolet Silverado 3500HD varies by engine and drivetrain. In general, the gasoline 6.6L V8 models deliver in the low-teens mpg combined, while the Duramax 6.6L Turbo-Diesel typically sits in the mid-teens to high-teens combined. Actual mileage depends on cab/bed configuration, axle ratio, payload, and whether the truck is 2WD or 4WD.
In more detail, EPA estimates show a wide range for this heavy-duty truck. The figures below reflect typical configurations used by truck owners for towing, hauling, and everyday use. Always check the exact window sticker or fueleconomy.gov for the precise rating of a specific build and model year.
Engine options and mpg ranges
Gasoline 6.6L V8
The gasoline-powered Silverado 3500HD with the 6.6L V8 generally posts lower mileage than the diesel, with variations driven by drivetrain and payload.
- 2WD (two-wheel drive) configurations: approximately 11–14 mpg combined.
- 4x4 (four-wheel drive) configurations: approximately 10–13 mpg combined.
These ranges reflect typical use cases involving daily driving, light-to-moderate towing, and standard payloads. Real-world results can vary with miles driven, weather, and maintenance.
Duramax 6.6L Turbo-Diesel
The Duramax diesel option offers better fuel efficiency, particularly on highways and when towing, thanks to its higher torque and diesel efficiency characteristics.
- 2WD (two-wheel drive) configurations: approximately 16–19 mpg combined.
- 4x4 (four-wheel drive) configurations: approximately 15–18 mpg combined.
Diesel models often show greater efficiency when carrying heavy loads or towing long distances, but actual results depend on axle ratios, wheel choices, and operating conditions.
What affects MPG on the Silverado 3500HD
Fuel economy on a heavy-duty pickup is influenced by several factors beyond engine choice. Payload, towing volume, driving style, terrain, and accessory equipment (like bed options and auxiliary gear) can all shift real-world mpg. The truck’s axle ratio, transmission tuning, and tire size also play significant roles in efficiency.
Practical considerations for buyers
If you’re shopping for a 3500HD and fuel economy matters, consider the diesel option for higher efficiency on long highway trips or when towing heavy loads. For shorter trips or urban use, the gasoline variant may be adequate, but expect lower mpg. Always verify the EPA ratings for the exact configuration you’re considering and compare them with your typical workload to estimate annual fuel costs.
Summary
In summary, the Chevy Silverado 3500HD’s mpg varies widely by engine and drivetrain. Gasoline 6.6L V8 models typically sit in the low-teens mpg combined, while Duramax 6.6L diesel models commonly range from the mid-teens to high-teens combined. For precise figures, consult the EPA window sticker or fueleconomy.gov for the model year and configuration you’re evaluating, and factor in payload and towing plans to estimate real-world fuel costs.
