How many miles does a Chevy Tahoe get on gas?
Across current Tahoe configurations, you can expect roughly 15 to 25 miles per gallon, depending on engine and drivetrain. Diesel models typically deliver the best efficiency, while larger V8s burn more fuel. This article breaks down mpg estimates by configuration and what to expect in real-world driving.
What determines Tahoe fuel economy
Fuel economy for the Tahoe depends on engine choice, whether you drive 2WD or 4WD, payload, tire size, and driving style. The figures below reflect typical EPA estimates for recent model years and common configurations.
- 5.3L V8 gasoline engine, 2WD: approximately 18–20 mpg combined
- 5.3L V8 gasoline engine, 4WD: approximately 17–19 mpg combined
- 6.2L V8 gasoline engine, 2WD: approximately 17–19 mpg combined
- 6.2L V8 gasoline engine, 4WD: approximately 16–18 mpg combined
- 3.0L Duramax diesel engine, 2WD: approximately 23–25 mpg combined
- 3.0L Duramax diesel engine, 4WD: approximately 22–24 mpg combined
Note that these ranges are approximate and can vary with model year, transmission, tire size, and optional equipment. In real-world driving, individual results may differ from EPA estimates.
Diesel vs gasoline: what to expect
Diesel-powered Tahoes generally deliver higher mpg, especially on long highway trips, due to the higher energy density of diesel and turbocharged efficiency. Gasoline versions offer strong performance, but typically fall short of diesel in efficiency, particularly with the larger 6.2L V8.
Real-world factors that affect mileage
In practice, mpg can be influenced by terrain, load, weather, and driving style. The following factors commonly affect efficiency and how to optimize it.
- Load and payload: heavier loads reduce mpg; remove unnecessary gear when possible.
- Tire choice and pressure: underinflated tires waste fuel and can reduce handling.
- Maintenance: regular oil changes, air filter, spark plugs, and fuel system upkeep help maximize efficiency.
- Driving habits: aggressive acceleration, high speeds, and excessive idling lower mpg; steady speeds and smooth acceleration improve it.
- Terrain and trip type: highway cruising tends to yield better mpg than frequent city stops or steep climbs; cold weather can also lower mpg.
By considering these factors, Tahoe owners can maximize fuel economy without sacrificing capability.
Summary
The Chevy Tahoe’s gas mileage varies widely by configuration. In general, gasoline V8 models run around 17–20 mpg combined, while the diesel-equipped versions typically reach the mid-20s combined. Real-world results depend on load, terrain, and driving style, but with mindful driving and routine maintenance, you can maximize miles per gallon across most Tahoe configurations.
How many miles can a Chevy Tahoe go on a full tank of gas?
A Chevy Tahoe can go between approximately 360 and 672 miles on a full tank, depending on the model year, engine type, and driving conditions. Models with the diesel engine can achieve the highest range, while a typical gas-powered V8 will get a highway range of around 480 miles.
- Gasoline engine: Around 480 miles on the highway for models with the 5.3L or 6.2L V8.
- Diesel engine: Up to 672 miles on the highway for models with the 3.0L turbo diesel engine.
- Factors that influence mileage: Your actual range will vary based on factors like city vs. highway driving, speed, towing, and road conditions.
- Older models: Older models with smaller tank capacities will have a lower range.

The Chevy Tahoe engine size includes a powerful 5.3-liter V8 engine producing 355 horsepower.
Do Tahoes get good gas mileage?
Fuel Economy and Real-World MPG
On our 75-mph highway route, a four-wheel-drive, 6.2-liter Tahoe achieved 20 mpg. The last time we tested a diesel-powered Tahoe on that same route was in 2021, and we observed 27 mpg.
What is the mileage on a Chevy Tahoe?
The standard Chevy Tahoe model gets an EPA-estimated 15/20/17 MPG (City/Highway/Combined),1 but a model with 2WD and the 3.0-liter Duramax Turbo Diesel engine scores a higher EPA-estimated 21/28/24 MPG (City/Highway/Combined).
