How many miles per gallon does a 2007 Chevy Silverado diesel get?
In short, a 2007 Chevy Silverado diesel typically achieves roughly 14–18 miles per gallon in mixed driving, with highway numbers often near 17–20 mpg and city driving lower around 12–15 mpg depending on configuration and load.
What to expect from EPA ratings and real-world mileage
The EPA numbers for the 2007 Duramax-powered Silverado 2500HD varied by drivetrain, cab style and bed length. In general, diesel models offered better highway efficiency than city driving, but real-world results depend heavily on how the truck is used—towing, payload, and driving conditions can all swing mileage significantly.
- City driving: typically 12–15 miles per gallon
- Highway driving: typically 17–20 miles per gallon
- Combined/mixed driving (typical use): roughly 14–18 miles per gallon
In summary, you should expect mid-teens mpg in typical mixed-use scenarios, with highway runs giving the best mileage and City driving pulling it down, especially when towing or carrying heavy loads.
Which configurations affect mpg
Fuel economy for the 2007 Silverado diesel depends on several configuration and usage factors. Below are the main variables that influence mpg on these trucks:
- Drivetrain: two-wheel drive (2WD) versus four-wheel drive (4WD)
- Cab and bed configuration: regular cab, extended cab, crew cab, and bed length impact weight and aerodynamics
- Towing and payload: towing heavy trailers or carrying heavy loads reduces mpg
- Tire size and condition: larger or lower-pressure tires increase rolling resistance and reduce efficiency
- Driving style and terrain: steady cruising at highway speeds improves mpg; stop-and-go city driving lowers it
Ultimately, mileage will vary based on how the truck is used day-to-day, maintenance history, and aftermarket equipment.
Tips to maximize mpg
Even with an older diesel pickup, several best practices can squeeze extra fuel economy out of your Silverado:
- Keep tires inflated to the manufacturer's recommended pressure
- Perform regular maintenance: air filter, fuel system, oil changes, and fuel injector health
- Minimize unnecessary weight and cargo; remove racks or accessories that create wind resistance when not needed
- Avoid prolonged idling; use cruise control on highways when appropriate
- Plan efficient routes to reduce stops, hills, and stop-and-go traffic
Regional conditions, maintenance history, and how the truck is used (especially towing) will largely determine the real-world mpg you experience.
Summary
The 2007 Chevy Silverado diesel delivers usable efficiency for a heavy-duty pickup, with typical mpg landing in the mid-teens for mixed use and higher highway figures around the upper teens to around 20 mpg, depending on drivetrain, configuration, and load. Real-world results will vary, but understanding the key factors can help you set realistic expectations and optimize fuel economy where possible.
