How many miles per gallon does a 2007 Chevy 3500 get?
There isn’t a single mpg figure for a 2007 Chevy 3500; mileage varies by engine choice, drivetrain, payload, and driving conditions. In general, gasoline-powered models sit in the low-to-mid teens for combined efficiency, while diesel versions tend to reach the high teens to low twenties on highway drives.
This article breaks down the typical fuel economy you can expect from the 2007 Silverado 3500 family, explains how different configurations affect efficiency, and offers practical guidance for estimating your own mpg based on real-world use.
Engine options in the 2007 Silverado 3500
The 2007 Silverado 3500 offered a range of powertrains, including two gasoline V8 options and a diesel, with mpg largely influenced by payload, transmission, and 4x4 vs. 2WD setup.
Gasoline engines
The gasoline lineup consisted of two V8 options. The mpg ranges below reflect typical EPA estimates across common configurations, though actual numbers can vary with drivetrain and payload.
- 6.0L Vortec V8 (gasoline) — generally about 12–14 mpg combined, with lower figures for 4x4 and heavier payloads (roughly 11–15 mpg depending on configuration).
- 8.1L Vortec V8 (gasoline) — typically around 11–13 mpg combined, with similar caveats about 4x4 and load affecting the actual figure.
Gasoline-powered 3500s in daily use often land in the low-to-mid teens for mixed driving, and payload-heavy or towing scenarios can push mpg downward by a few points.
Diesel engine
The diesel option was the 6.6L Duramax V8, paired with an Allison transmission in most configurations. Duramax-equipped trucks generally deliver superior highway efficiency and strong torque for towing, which translates into better mpg under many conditions. The figures below reflect typical ranges for common setups (2WD/4WD, automatic).
- 6.6L Duramax Diesel — roughly 18–20 mpg combined, with city mpg in the mid-teens and highway mpg around 20+ under light loads. Heavier towing or payload can reduce these numbers.
Diesel-equipped 3500s typically outperform gasoline variants on highway runs, especially when not carrying a heavy load, though real-world mpg varies with tow weight and terrain.
How to determine the exact MPG for your 2007 3500
To get an accurate figure for your specific truck, consult the original EPA window sticker for the exact configuration and keep a log of fill-ups over a few hundred miles. Real-world mileage is influenced by payload, tow capacity, terrain, altitude, tire size, and driving habits.
Summary
The 2007 Chevy Silverado 3500’s fuel economy depends heavily on the chosen powertrain. Gasoline models (6.0L and 8.1L) typically yield about 12–14 mpg combined under typical use, while the 6.6L Duramax diesel commonly achieves roughly 18–20 mpg combined, with better highway efficiency generally. For an exact figure, check the specific vehicle’s EPA label and track your own fuel usage across a representative driving mix.
How many miles per gallon does a 3500 diesel get?
Efficiency leaders: Chevrolet/GMC 2500/3500 Duramax 6.6L, Ford F-250/F-350 6.7L, Ram 2500/3500 6.7L. Unloaded highway runs often deliver 17–20 mpg when geared sensibly.
What year should I have my Chevy Silverado 3500 to avoid?
The 2012 Silverado 3500HD stands out as the worst model year according to CarComplaints.com, with numerous issues reported by owners. A major concern is the dashboard cracking, even in low-mileage vehicles. Some owners experienced this problem with as little as 26,000 miles on the odometer.
What is the gas mileage on a 2007 Chevy 3500?
The price to pay for that impressive towing power is dirty injectors and a clogged air filter. Achieving 13-15 mpg is more in line with what you should expect, and 11 mpg isn't too far off from that. Adjusting how you distribute weight on the truck can also impact towing fuel economy.
What fuel mileage does a 6.6 l Duramax diesel get?
The 6.6L Duramax engine's MPG varies, but typically ranges from 15-18 MPG for mixed driving and 17-20 MPG for unloaded highway driving. Actual mileage depends heavily on factors like driving conditions, towing, and the specific model year. Some newer models achieve higher efficiency, with a 2025 Silverado HD hitting 20.4 MPG on a controlled highway loop.

- Mixed/City: Around 15 MPG or lower, especially with stop-and-go traffic.
- Highway (unloaded): Typically 17-20 MPG, but can vary with speed.
- Towing: Expect significantly lower mileage, often in the 10-14 MPG range depending on the load and terrain.
Factors that influence MPG:
- Towing and load: Hauling heavy loads reduces fuel efficiency.
- Driving conditions: Hilly terrain or stop-and-go city traffic lowers MPG.
- Vehicle age and break-in: Newer trucks may improve after an initial break-in period, with some owners reporting increased mileage after a few thousand miles.
- Other factors: Speed, road conditions, and factors like the truck's emissions system (e.g., temporary DPF regen cycles) can also have an effect.
