How much gas does a Tahoe burn?
Fuel economy depends on the engine and drivetrain you choose. In recent models, a Chevrolet Tahoe typically gets around 15–16 miles per gallon in the city and about 20–23 mpg on the highway, with the 3.0L Duramax diesel offering the best highway efficiency (roughly 28–30 mpg on highway driving).
To understand why these numbers vary, it’s helpful to know how the Tahoe is configured. The SUV’s weight, powertrain, and whether it’s driving with two or four wheels driven all influence how much gas it uses. The following sections break down the main factors and the EPA estimates by configuration.
What affects a Tahoe's fuel economy
Fuel consumption is shaped by several interrelated factors. The key ones include:
- Engine choice: Smaller, naturally aspirated engines tend to sip fuel more slowly than larger V8s, while diesel engines are typically more efficient on sustained highway driving.
- Drivetrain: Two-wheel drive (2WD) generally uses less fuel than four-wheel drive (4WD) due to reduced drivetrain losses and weight.
- Cargo and towing: Heavier loads and towing increase energy demand, lowering mpg.
- Driving conditions: City stop-and-go traffic, hills, and headwinds raise fuel use compared with steady highway cruising.
- Aerodynamics and accessories: Roof racks, cargo carriers, and aerodynamic drag can reduce gas mileage, especially at higher speeds.
- Maintenance and tires: Proper maintenance, tire pressure, and tire type (rolling resistance) affect efficiency.
In practice, a Tahoe’s mpg can swing based on how you use the vehicle, not just what’s under the hood. Regular maintenance, prudent driving habits, and proper tire care can help you get closer to the EPA estimates.
EPA-estimated fuel economy by configuration
Before reading the list, note that EPA numbers vary by model year, trim, and equipment. Use these figures as a general guide and check the window sticker for your exact configuration.
- 5.3L V8, 2WD: approximately 15 mpg city / 20 mpg highway / around 17 mpg combined.
- 5.3L V8, 4WD: approximately 15 mpg city / 20 mpg highway / around 17 mpg combined.
- 6.2L V8, 2WD: approximately 14 mpg city / 20 mpg highway / around 16 mpg combined.
- 6.2L V8, 4WD: approximately 14 mpg city / 19 mpg highway / around 16 mpg combined.
- 3.0L Duramax Diesel, 2WD: approximately 21 mpg city / 28 mpg highway / around 24 mpg combined.
- 3.0L Duramax Diesel, 4WD: approximately 20 mpg city / 27 mpg highway / around 23 mpg combined.
Real-world fuel economy often trails these numbers, sometimes by a few mpg, depending on driving style, terrain, load, and weather. For long highway trips or daily commuting, the diesel option tends to deliver the strongest highway efficiency, while the larger gasoline V8s offer robust towing and power at the expense of mpg.
Tips to maximize fuel economy
Small changes can add up over time. Consider these practices to help squeeze more mpg out of your Tahoe:
- Keep tires properly inflated and aligned to reduce rolling resistance and drag.
- Avoid unnecessary idling and plan routes to minimize stop-and-go driving.
- Limit roof gear and exterior cargo that increase aerodynamic drag at highway speeds.
- Maintain a steady speed on highways and use cruise control where appropriate.
- Schedule regular maintenance, including spark plugs, air filters, and fuel system checks.
By understanding the trade-offs among engine options and drivetrain configurations, you can better estimate running costs and choose the Tahoe that best fits your needs and budget.
Summary
The Chevrolet Tahoe’s gas usage varies mainly with engine choice and drivetrain. Gasoline versions with the 5.3L or 6.2L V8 usually hover in the mid-teens to low 20s mpg, while the 3.0L Duramax diesel delivers higher highway efficiency, often in the low-to-mid 20s combined and around 28–30 mpg on long highway trips. Real-world mileage will depend on how you drive, load, and maintain the vehicle. Planning around these factors helps you predict fuel costs more accurately and optimize performance.

Is the Chevy Tahoe good on gas?
What are the most fuel-efficient years for the Chevy Tahoe? The most fuel-efficient model years for the Chevy Tahoe are typically more recent. For example, the 2024 Chevy Tahoe equipped with 2WD and the 3.0-liter Turbo Diesel engine achieves an impressive 21/28/24 MPG (City/Highway/Combined).
How many miles does a Tahoe get on a full tank?
A Tahoe's range on a full tank depends on the engine and drivetrain, but can be up to 480 miles on the highway for a gasoline model or up to 672 miles for a diesel model. With a 24-gallon tank, a gasoline V8 engine typically gets about 360–480 miles per tank, while the diesel engine can get significantly more range.
Gasoline engine (5.3L V8)
- Highway: Approximately 480 miles (20 mpg highway x 24 gallons)
- City: Approximately 360 miles (15 mpg city x 24 gallons)
Gasoline engine (6.2L V8)
- Highway: Approximately 480 miles (20 mpg highway x 24 gallons)
- City: Approximately 336 miles (14 mpg city x 24 gallons)
Diesel engine (3.0L Duramax)
- Highway: Up to 672 miles (28 mpg highway x 24 gallons)
- City: Up to 504 miles (21 mpg city x 24 gallons)
What is the gas mileage on a 5.3 Tahoe?
A Chevy Tahoe with the 5.3L V8 engine gets an EPA-estimated 15 mpg in the city and 20 mpg on the highway for both 2WD and 4WD models. These estimates can vary slightly based on factors like the specific model year, features, and driving conditions.
