The 2015 GMC Yukon K1500 4WD with the 6.2L V8 gets 16 MPG combined, which isn’t amazing, and it shouldn’t be expected. People don’t buy this vehicle for its frugality. It’s bought by people who need serious towing capability, the confidence of four-wheel drive, and the space to haul a family and their gear without compromise. For those buyers, the thirsty V8 is simply the price of admission.

City and highway performance

The EPA estimates of 14 MPG in the city and 21 MPG on the highway give a clearer picture of the Yukon’s fuel consumption. Stop-and-go urban driving emphasizes the vehicle’s weight and power, forcing the engine to work harder to get up to speed. The highway figure is more palatable, demonstrating that the Yukon can achieve relatively respectable efficiency when cruising at a steady speed. Expect those highway numbers to drop significantly when towing, as the big V8 is sure to feel the strain. The 6.2L V8 sends power to the wheels via a 6-speed automatic transmission.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2015 GMC Yukon K1500 4WD 6.2L 8-cyl at $2,750. This figure is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the type of driving you do (city vs. highway), and the price of gasoline in your area. Consider this a benchmark more than a hard-and-fast number.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy can vary. Aggressive driving, carrying heavy loads, and frequently using four-wheel drive will all decrease fuel efficiency. On the other hand, those who drive conservatively and primarily on the highway may find they can match or even slightly exceed the EPA’s estimates.

Consider your own driving patterns to estimate what you will achieve. Keeping up on maintenance of your Yukon is also key. Maintaining proper tire inflation and air filter cleanliness will help maximize fuel economy.

How it compares

Compared to other large SUVs, the 2015 Yukon’s fuel economy is predictable. A similarly equipped 2015 Chevrolet Tahoe 4WD, the same vehicle under a different badge, achieves the same 16 MPG combined.

The 2015 Ford Expedition gets 18 MPG combined with its 3.5L EcoBoost engine, which does mean sacrificing the powerful sound and feel of a large V8. Looking at all GMC fuel economy data will also help provide perspective.

Tips to maximize efficiency

Because this Yukon is equipped with a large displacement V8, smooth throttle inputs are key. Pressing hard on the accelerator will immediately trigger a downshift and a surge of fuel consumption. Instead, try to anticipate traffic and maintain momentum, allowing the engine to operate in its most efficient range.

Tire pressure matters. Ensure that your tires are inflated to the recommended pressure, which can be found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, forcing the engine to work harder. Check tire pressures monthly for optimal results.

Minimize idling time. The 6.2L V8 consumes a significant amount of fuel even when stationary. If you’re going to be stopped for more than a minute or two, turn off the engine. Modern vehicles are designed to restart quickly and efficiently, making this a simple way to save fuel over time.

Consider the grade of gasoline you are using. While the Yukon’s 6.2L V8 may not REQUIRE premium fuel, using a higher octane fuel could potentially improve performance and efficiency, especially when towing or carrying heavy loads. Experiment to see if it makes a noticeable difference in your driving experience.

Regular maintenance can make a difference. Keep up with scheduled oil changes, air filter replacements, and tune-ups. A well-maintained engine runs more efficiently and delivers better fuel economy. See more YUKON MPG across all years for more data.
