16 MPG combined is the reality for the 2022 Chevrolet Tahoe 2WD with the 6.2L V8, and it’s a number most buyers of this configuration have already factored into their ownership costs. This isn’t a vehicle purchased for its fuel sipping nature; it’s bought for its immense towing capacity, comfortable passenger accommodations, and imposing road presence. Fuel economy is secondary, even a tertiary consideration, in the minds of those who specifically seek out this powerful engine in a two-wheel drive Tahoe.

City and highway performance

The EPA estimates this Tahoe variant achieves 14 MPG in the city and 20 MPG on the highway. These figures represent ideal scenarios. Stop-and-go traffic will drag the city MPG down, likely into the single digits if you’re truly aggressive. Maintaining 75-80 MPH on the open highway can easily reduce that 20 MPG figure. The ten-speed automatic transmission tries its best to keep the engine in its most efficient operating range by rapidly upshifting, but the sheer displacement of the 6.2L V8 means it needs a heavy dose of fuel to get all 5,300+ pounds moving.

Annual fuel cost

The EPA estimates an annual fuel cost of $3,600 for this specific Tahoe. This calculation is based on driving 15,000 miles per year and uses the national average fuel price at the time of the EPA’s testing. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use (premium is recommended for the 6.2L), and fuel prices in your area. Expect to spend significantly more than $3,600 if you do a lot of towing, aggressive acceleration and braking, or live in an area with high fuel costs.

Real-world expectations

Owners typically report real-world MPG figures that are in line with, or slightly below, the EPA estimates. A reasonable expectation is somewhere between 12-15 MPG in mixed driving. Towing a trailer will severely reduce your fuel economy, dropping it into the 8-10 MPG range or even lower, depending on the trailer’s weight and how aerodynamic it is. The 6.2L V8 is a powerful engine, but expect to pay for that performance at the pump.

How it compares

Direct competitors to the 2022 Tahoe, such as the Ford Expedition with its 3.5L EcoBoost V6, typically offer slightly better fuel economy, around 17 MPG combined. The GMC Yukon Denali, which also offers a 6.2L V8, will deliver similar numbers to the Tahoe. Compared to the Nissan Armada, even with it’s 5.6L V8, the Tahoe is roughly equivalent. Within the Chevrolet family, opting for the 5.3L V8 or the Duramax diesel in a Tahoe will yield demonstrably better fuel economy, at the expense of the 6.2L’s raw power. The 6.2L is specifically chosen for its power and the sound it makes, an experience that outweighs the slight MPG variations.

Tips to maximize efficiency

Use cruise control whenever possible on the highway. Maintaining a consistent speed will reduce unnecessary acceleration and deceleration, helping to improve fuel economy. Resist the urge to frequently punch the throttle, as the 6.2L V8 is very sensitive to aggressive driving styles. Gentle acceleration and smooth braking will make a noticeable difference over time.

Ensure your tires are properly inflated. Underinflated tires increase rolling resistance, which forces the engine to work harder and burn more fuel. Check your tire pressures regularly and inflate them to the manufacturer’s recommended specifications. The correct pressure is generally listed on a sticker inside the driver’s side door.

Consider using a fuel additive designed to clean fuel injectors. Over time, fuel injectors can become clogged, which can negatively impact engine performance and fuel economy. Cleaning your injectors can help to restore optimal fuel delivery and improve MPG.

Minimize idling time. Letting the engine idle for extended periods wastes fuel. If you’re going to be stopped for more than a minute or two, turn off the engine. Modern engines are designed to start quickly and reliably, so there’s no need to let them run unnecessarily.

When possible, travel lighter. Carrying unnecessary weight in your Tahoe will reduce fuel economy. Remove any items you don’t need from the vehicle, especially heavy items in the cargo area. The less weight the engine has to move, the better your MPG will be.
