19 MPG combined is the reality if you own a 2017 GMC Yukon C1500 XL 2WD with the 5.3L V8. It’s a number that almost seems old-fashioned, but it’s the price you pay for serious passenger and cargo capacity, combined with the proven reliability of a traditional American V8 drivetrain. This isn’t a vehicle bought to save on gas; it’s bought for hauling kids, gear, and occasionally a trailer, and doing so with the confidence that it will handle the job without complaint for years to come.

City and highway performance

The EPA estimates suggest 16 MPG in the city and 23 MPG on the highway. The city figure reflects the inherent inefficiency of a large, heavy vehicle navigating stop-and-go traffic. The 5.3L V8 requires a significant amount of fuel to get its mass moving from a standstill. The highway number of 23 MPG is more achievable during steady-state cruising.

The six-speed automatic transmission helps here, allowing the engine to settle into a relatively low RPM at highway speeds. Still, the Yukon XL is not aerodynamic, and wind resistance plays a major role in highway fuel consumption. Buyers should understand they are driving a large box pushing through the air.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 GMC Yukon C1500 XL 2WD at $2,300. This figure is based on driving 15,000 miles per year, with 55% of those miles driven in the city and 45% on the highway, using national average fuel prices.

While individual costs will vary based on driving habits and local fuel prices, this provides a benchmark for understanding the ongoing expense of owning a vehicle of this size and capability. It’s a significant cost, and one that potential buyers must factor into their budget. Changes in fuel prices could impact your fuel costs, so keeping an eye on those changes can help you plan better.

Real-world expectations

While the EPA estimates provide a baseline, real-world MPG can vary significantly. Aggressive driving, frequent short trips, and carrying heavy loads will all negatively impact fuel economy. Gentle acceleration, consistent highway speeds, and diligent maintenance can help you approach the EPA figures.

Keep in mind the long wheelbase Yukon XL is often fully loaded with passengers or equipment, and the buyer is often sacrificing some mileage to actually do the work they are designed to do.

How it compares

Compared to other full-size SUVs of its era, the 2017 Yukon XL’s fuel economy is within the expected range. A 2017 Ford Expedition 2WD with its 3.5L EcoBoost V6 is rated at 17 MPG city and 23 MPG highway, making for 19 MPG combined, matching the Yukon almost identically. The Nissan Armada from the same year, with its 5.6L V8, achieves around 14 MPG city and 19 MPG highway for 16 MPG combined, making it slightly less efficient than the Yukon.

All Gmc fuel economy data can be found online, and your mileage results with this specific year of Yukon may vary against the YUKON MPG across all years. These comparisons are key for buyers cross-shopping in the full-size SUV segment who may wonder if there is a more efficient option within the same class. Some buyers consider larger minivans, like the Honda Odyssey (19/28 MPG), but sacrifice towing capability and truck toughness for better mileage.

Tips to maximize efficiency

Gentle acceleration is crucial. The 5.3L V8 has plenty of torque, so there’s no need to mash the accelerator pedal. Smooth, gradual acceleration uses less fuel and reduces wear and tear on the engine and drivetrain. Avoid sudden bursts of speed and try to maintain a steady pace.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, which reduces fuel economy. Check your tire pressure regularly and inflate them to the recommended PSI (pounds per square inch) found on the driver’s side doorjamb. Ensure that your tires are in good condition and replace them them when they start to wear.

Limit idling time. Letting your Yukon XL 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 vehicles are designed to restart quickly and efficiently, so you won’t damage anything by turning it off and on.

Use cruise control on the highway. Maintaining a consistent speed on the highway can significantly improve fuel economy. Cruise control helps you avoid unnecessary acceleration and deceleration, which wastes fuel. Don’t depend 100% on cruise control in bad weather, but you should otherwise embrace this feature that the designers added.

Keep up with regular maintenance. A well-maintained engine runs more efficiently. Follow the manufacturer’s recommended maintenance schedule for oil changes, air filter replacements, and tune-ups. A clean air filter and fresh spark plugs can make a noticeable difference in fuel economy.
