17 MPG combined isn’t going to win any awards, but it’s the reality for drivers who need the capabilities of the 2019 GMC Yukon K1500 4WD with the 5.3L V8. These buyers aren’t prioritizing efficiency; they’re prioritizing space, towing capacity, and the peace of mind that comes with a strong, body-on-frame SUV. They have boats to haul, families to transport, and challenging weather conditions to conquer, and the Yukon delivers.

City and highway performance

The EPA estimates paint a clear picture: 15 MPG in the city and 21 MPG on the highway. The city figure reflects the demands placed on a large SUV in stop-and-go traffic. Frequent acceleration and braking take their toll.

The 21 MPG highway rating is more achievable in steady-state cruising, though even then, aerodynamic limitations and the weight of the vehicle keep it from being truly thrifty. The 6-speed automatic transmission, while generally smooth and reliable, isn’t as efficient as the 8- or 10-speed units found in some competitors, which also contributes to slightly lower fuel economy.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,600 for the 2019 GMC Yukon K1500 4WD, based on driving 15,000 miles per year and using national average fuel prices. This figure provides a benchmark for understanding the ongoing expense of owning a vehicle like the Yukon.

Keep in mind that your individual fuel costs will vary based on your driving habits, the type of fuel you purchase, and local fuel prices. If you drive more aggressively or spend a significant amount of time idling, your fuel costs will likely exceed the EPA estimate.

Real-world expectations

While the EPA provides a standardized test, real-world fuel economy often deviates from the official numbers. Drivers report slightly lower MPG than the EPA estimates, particularly in mixed driving conditions.

Towing, especially heavy loads, will dramatically reduce fuel economy, often dropping into the single digits. Factors such as tire pressure, vehicle maintenance, and ambient temperature can also influence real-world MPG. It’s essential to temper expectations and understand that the Yukon prioritizes capability over ultimate fuel efficiency. You can review YUKON MPG across all years.

How it compares

The 2019 Yukon’s fuel economy places it in the expected range for large, body-on-frame SUVs with V8 engines. A Ford Expedition with its turbocharged 3.5L EcoBoost V6 typically achieves slightly better fuel economy, around 17 MPG city and 23 MPG highway in 4×4 configuration. The Toyota Sequoia, with its reliable 5.7L V8, comes in lower, around 13 MPG city and 17 MPG highway. The Chevrolet Tahoe, mechanically similar to the Yukon, posts nearly identical MPG figures.

For buyers prioritizing less gas, the Expedition offers an alternative, but the Yukon caters to those who prefer the proven reliability and sound of a naturally aspirated V8. Be sure to view all Gmc fuel economy data.

Tips to maximize efficiency

Avoid aggressive acceleration and braking. The Yukon is a heavy vehicle, and rapid changes in speed require a significant amount of energy. Maintaining a steady speed and anticipating traffic conditions will help conserve fuel.

Ensure proper tire inflation. Underinflated tires increase rolling resistance, which forces the engine to work harder and consume more fuel. Check your tires regularly and inflate them to the recommended pressure listed on the doorjamb.

Minimize idling. Idling burns fuel without traveling any distance. If you anticipate being stopped for more than a minute or two, turn off the engine. Restarting the engine consumes less fuel than prolonged idling.

Reduce unnecessary weight. Carrying excessive cargo adds weight to the vehicle, which reduces fuel economy. Remove any unnecessary items from the Yukon to minimize the load on the engine.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which can improve fuel economy on long highway drives. However, avoid using cruise control in hilly terrain, as it can cause the transmission to shift frequently, negating some of the fuel savings.
