What Gas Mileage Does a GMC Yukon Get in Houston Driving?

Most fuel-economy answers stop at the window sticker. In Houston, the city rating decides more of your fill-ups than the highway number, because stop-and-go traffic and short trips fill so much of a local week. The diesel, the 5.3L V8 and the 6.2L V8 each suit a different Houston driver, and the EPA figures show where each one earns its keep. Group 1 Buick GMC North, a 4.4-star Google rated store on FM 1960 in northwest Houston, sells new Yukon and Yukon XL models.

What mpg should you expect from a Yukon on Houston roads?

A 2026 Yukon carries an EPA combined rating of 16 to 23 mpg, depending on drivetrain and engine. On Houston roads the city number matters most, because the EPA builds the combined figure by weighting city at 55% and highway at 45% (U.S. Environmental Protection Agency, 2026).

The diesel leads on city, at 21 in 2WD, against 15 for either gasoline V8. Stop-and-go driving is exactly where that city number starts paying you back.

Which Yukon engine gets the best gas mileage for Houston commuters?

The 3.0L Duramax diesel posts the best EPA combined rating in each drivetrain, at 23 mpg in 2WD and 22 mpg in 4WD. The two V8s split the rest of the decision. In 2WD the 5.3L and the 6.2L both rate 15 city, 20 highway and 17 combined, so the bigger V8 costs no combined mpg there. In 4WD the 5.3L rates 15 city and 17 combined, against 14 city and 16 combined for the 6.2L.

If most of your week is stop-and-go on the freeways and surface streets around FM 1960, the diesel’s 21 city rating is the strongest number on the sheet. If you need a gasoline V8 with 4WD, the 5.3L has the better city and combined figures of the two. If you want the 6.2L, rear-wheel drive is where it rates the same as the 5.3L.

Does 4WD cost you mpg in Houston driving?

Yes. Every Yukon engine rates lower in 4WD than in 2WD on at least one figure. The 5.3L holds 15 city and 17 combined in both drivetrains but gives up one mpg on the highway, 20 in 2WD against 19 in 4WD, while the 6.2L drops a point on city, 15 against 14, and a point on combined, 17 against 16. The diesel moves from 21 city to 20 and from 23 combined to 22.

For Houston, the city column is the one to watch. Choose 4WD when the drive or the road calls for it, and count its cost in the city number, where your miles are.

How much does a week of Houston driving cost in Yukon fuel?

Your weekly fuel cost is your weekly miles divided by the combined mpg of the Yukon you are weighing, then multiplied by what you pay for a gallon. Run the same miles through each rating and the gallon count moves with the engine and drivetrain, not the trim. The 2WD diesel’s 23 combined needs fewer gallons per mile than either gasoline V8’s 17.

The number that matters most is your own weekly mileage, so start with how far you drive in a normal week and check each engine against it.

How does the Yukon XL compare with the Yukon on fuel economy?

The Yukon XL matches the Yukon on the 2WD 5.3L, the 4WD 6.2L and both diesels.

If the longer body is the reason you are looking at the XL, the diesel is the engine that keeps its rating across both bodies.

Frequently asked questions

What is the 2025 GMC Yukon’s EPA fuel economy?

For the 2026 model year, EPA-certified Yukon ratings run from 14 to 21 mpg city, 18 to 26 mpg highway and 16 to 23 mpg combined, depending on drivetrain and engine. The diesel holds the top city rating at 21 in 2WD, and the 4WD 6.2L sits at the low end with 14 city and 16 combined.

Does hot Houston weather lower Yukon gas mileage?

Heat is part of the EPA test. Its five-cycle schedule includes a hot-weather run with air conditioning under a 95°F sun load (U.S. DOE/EPA, fueleconomy.gov, Detailed Test Information, undated). EPA also adjusts lab city and highway figures with a standard 0.7 factor to account for real-world effects such as air conditioning (U.S. EPA, EPA.gov, Fuel Economy and EV Range Testing, 2026).
