How many miles per gallon does a 6.2 Tahoe get?

The Chevrolet Tahoe with the 6.2-liter V8 typically returns in the mid-teens to the low 20s per gallon, depending on year, drivetrain, and driving conditions. Expect roughly 14–15 mpg in city driving, about 20–23 mpg on the highway, and a combined figure around 17–19 mpg for recent models.

Gas mileage for the Tahoe’s 6.2L V8 is influenced by multiple variables, including whether the SUV is equipped with two-wheel drive (2WD) or four-wheel drive (4WD), how heavily it’s loaded or towing, terrain, weather, and even tire choice. The following breakdown provides a practical guide to current expectations and how they can vary year to year.

What affects the fuel economy of the 6.2L Tahoe

Several factors combine to determine actual mpg. The drivetrain, payload, towing duties, and driving habits all play a role, and EPA estimates can shift a bit from year to year as the model evolves.

Before examining the numbers, it’s useful to understand the main influences on mpg for a large SUV like the Tahoe:



• Drivetrain configuration (2WD vs. 4WD)


• Towing and payload weight


• Driving conditions (city vs. highway, hills, cold weather)


• Tire size and inflation, aerodynamics (roof racks, accessories)


• Maintenance and driving style

These factors explain why the same model year can show different mpg on the window sticker versus real-world driving.

Typical numbers by drivetrain and year

For recent model years, EPA estimates place the 6.2L Tahoe in roughly the following ranges. Note that actual mileage will vary with conditions and equipment; these are typical figures for 2WD and 4WD configurations.

• 2WD (6.2L): City about 14–15 mpg; Highway about 21–23 mpg; Combined roughly 17–19 mpg.


• 4WD (6.2L): City about 14–15 mpg; Highway about 20–22 mpg; Combined roughly 17–19 mpg.

Recent model-year guidance tends to cluster around these ranges, with small variations due to updates in transmission tuning, aero tweaks, or tire choices.

Model-year notes

Across the 2020s, the Tahoe’s 6.2L V8 has remained a performance-oriented option with mpg that lag behind smaller engines and hybrids. Buyers should expect EPA figures in the ranges above and should consider real-world factors like towing or heavy cargo, which can reduce mpg significantly.

How to maximize mpg on a 6.2 Tahoe

To improve efficiency, owners can adopt a few practical strategies. The following list outlines common approaches that can yield incremental gains over time.

• Keep tires inflated to the recommended pressure for better rolling resistance.


• Minimize payload and remove roof racks when not needed to reduce aerodynamic drag.


• Use cruise control on highways to maintain a steady speed.


• Plan trips to combine errands and reduce idling time.


• Perform regular maintenance (air filters, spark plugs, oil changes, alignment) to keep the engine running efficiently.

Even small improvements can add up, especially on longer drives or frequent highway commuting.

Summary

A 6.2-liter Tahoe typically delivers roughly 14–15 mpg in city driving, about 20–23 mpg on the highway, and a combined figure around 17–19 mpg for recent years. Exact numbers depend on model year, whether the vehicle is 2WD or 4WD, towing, payload, and driving conditions. For the most precise figure, check the EPA ratings for the specific year and configuration or review the vehicle’s window sticker.

Is a 5.3 or 6.2 engine better gas mileage?

The 5.3L and 6.2L engines have very similar fuel economy, with official EPA estimates showing the 5.3L at 16 mpg city / 21 mpg highway and the 6.2L at 16 mpg city / 20 mpg highway. Real-world mileage can vary depending on factors like vehicle trim, driving style, and whether premium fuel is used, but the two engines are not significantly different in terms of fuel efficiency.

• City MPG: Both engines are estimated to get around 16 mpg in the city. 
• Highway MPG: The 5.3L is slightly better, with an estimated 21 mpg on the highway compared to the 6.2L's 20 mpg. This difference is considered marginal. 
• Real-world variations: Actual mileage can fluctuate based on factors like the specific vehicle's trim level, wheel and tire size, driving habits, and use of premium fuel (which is recommended for the 6.2L to achieve its best performance and economy).

What is the gas mileage on a 6.2 Tahoe?

A Chevy Tahoe with the 6.2L V8 engine gets approximately 14 mpg in the city and 19-20 mpg on the highway. The exact highway mileage varies slightly by model year and drivetrain, with 2WD models achieving around 20 mpg and 4WD models getting about 18-19 mpg. 
City and highway MPG by drivetrain

• 2WD (Two-Wheel Drive):
  • City: 14 mpg
  • Highway: 20 mpg
• 4WD (Four-Wheel Drive):
  • City: 14 mpg
  • Highway: 18-19 mpg 

Other factors

• Model Year: While the MPG ratings are consistent across recent model years like 2023, 2024, and 2025, there might be minor variations. 
• Real-world vs. EPA: Real-world results can vary. For example, some drivers report slightly higher highway mileage, like 18 mpg, even on 4WD models. 

Which Tahoe gets the best gas mileage?

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).
