How many miles can a Chevy Suburban go on a full tank of gas?
Across typical configurations, a Chevy Suburban can travel roughly 500 to 750 miles on a full 31-gallon tank, depending on the engine and drivetrain. Diesel variants tend to stretch farther than gasoline ones.
What follows is a concise breakdown of the key factors and estimated ranges for common Suburban setups, based on current model-year specifications and EPA-style fuel-economy figures.
What affects the range
Range depends on the size of the fuel tank, the vehicle’s efficiency (miles per gallon), whether you’re driving in two-wheel drive or four-wheel drive, and real-world conditions such as terrain, payload, and driving style. The Suburban typically uses a 31-gallon tank across its gasoline and diesel variants, with fuel economy varying by engine and drive configuration.
Estimated range by configuration
This list provides rough per-tank mileage estimates using a 31-gallon tank and typical EPA-style combined fuel economy for each configuration. Actual miles will vary with how you drive and under different loads.
- Duramax 3.0L turbo-diesel (2WD or 4WD): about 23 mpg combined, approximately 700–730 miles per tank.
- Gasoline 5.3L V8 (2WD): about 18 mpg combined, roughly 550–560 miles per tank.
- Gasoline 5.3L V8 (4WD): about 17 mpg combined, roughly 510–530 miles per tank.
- Gasoline 6.2L V8 (2WD): around 17–18 mpg combined, roughly 520–560 miles per tank.
- Gasoline 6.2L V8 (4WD): around 16–17 mpg combined, roughly 490–525 miles per tank.
Takeaway: The diesel Suburban offers the best per-tank range, while the larger gasoline V8s burn more fuel, especially with four-wheel drive and heavier loads.
Notes on real-world figures
These numbers reflect commonly configured Suburbans for recent model years. Actual mileage varies with terrain, speed, cargo, climate control use, and maintenance. If you’re planning a long road trip, consult the exact EPA estimates for the specific trim and year you’re considering, and factor in a safety margin for fuel stops.
Summary
In sum, a Chevy Suburban typically delivers about 500–750 miles per full tank, with diesel versions offering the strongest range and gasoline variants showing somewhat lower figures depending on engine and drive configuration. Real-world results will depend on driving conditions and payload.
