18 MPG combined isn’t going to win any fuel-sipping contests, but for the 2017 GMC Yukon K1500 4WD with the 5.3L V8, it’s what you get for being in a very specific club. This truck isn’t about maximizing every last drop of fuel; it’s about confidently hauling a boat to the lake, ferrying a large family across state lines, and projecting capability. Fuel economy is a secondary concern for most buyers of this Yukon, utility and comfort are important.

City and highway performance

The EPA estimates for the 2017 Yukon K1500 4WD are 16 MPG in the city and 22 MPG on the highway. The city number reflects stop-and-go traffic and the SUV’s weight. The 22 MPG highway is respectable, showcasing the engine’s ability to cruise efficiently once up to speed, aided by the 6-speed automatic transmission. However, expect the highway number to drop when towing or carrying a heavy load.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2017 GMC Yukon K1500 4WD with the 5.3L V8 is $2,450. This 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, location, and current gasoline prices. Driving more aggressively or spending more time in city traffic will increase this annual expense. If you’re cross-shopping this model against the heavier 6.2L trims, or other full-sized SUVs, it provides a reasonable comparison.

Real-world expectations

The EPA numbers provide a baseline, however Yukon owners will likely experience figures slightly below those ratings in everyday driving. Factors such as wind resistance, tire pressure, and the vehicle’s condition can impact fuel economy. Owners who frequently use the four-wheel-drive system, especially off-road, should expect a further dip in MPG. Check owner forums and online resources for more information from drivers in similar conditions. You can also view YUKON MPG across all years to see how this model year compares to others.

How it compares

Compared to other full-size SUVs of its time, the 2017 Yukon’s fuel economy is standard for its class and drivetrain. For example, the Ford Expedition 4×4 with its 3.5L EcoBoost V6 was rated at 17 MPG combined. Chevrolet’s Tahoe 4WD, sharing a platform with the Yukon, has nearly identical fuel economy ratings with its 5.3L V8. The Toyota Sequoia, known for its reliability but not its efficiency, lagged behind at 15 MPG combined with its 5.7L V8. These comparisons are important for buyers who want size and capability while making an informed decision about fuel costs.

Tips to maximize efficiency

Gentle acceleration and smooth braking are key to improving fuel economy in any vehicle, especially in a large SUV like the Yukon. Avoid aggressive starts and anticipate traffic flow to minimize hard braking. The 5.3L V8 is powerful, so controlled power will save you money at the pump.

Properly inflated tires reduce rolling resistance and can improve fuel economy. Check your tire pressure regularly, especially during temperature changes, and maintain the recommended pressure listed on the driver’s side door jamb. This is often overlooked, but it makes a difference.

Reduce unnecessary weight inside the vehicle. Extra cargo adds strain to the engine and decreases fuel efficiency. Remove any items you don’t need for your daily driving. The Yukon has plenty of cargo space, organize it and remove excess clutter.

Consider using cruise control on the highway to maintain a consistent speed and avoid unintentional acceleration. This can help you achieve the best possible fuel economy during long trips. Remember to disengage it when driving in challenging weather conditions.
