16 MPG combined isn’t going to win any awards, but for the 2022 GMC Yukon XL 4WD with the 5.3L V8, it’s a figure that most buyers accept as the price of admission. This isn’t a vehicle purchased for its lower fuel costs. It’s bought by families who need serious space for passengers and cargo, often coupled with the ability to tow a boat or camper. They prioritize capability and comfort over using less gas, understanding that compromises have to be made.

City and highway performance

The EPA estimates for the Yukon XL 4WD 5.3L V8 break down to 14 MPG in the city and 19 MPG on the highway. The lower city figure reflects the stop-and-go driving conditions and the engine’s need to work harder to move this large SUV from a standstill. The highway number, while still not stellar, benefits from the 10-speed automatic transmission, which allows the engine to cruise at lower RPMs, improving efficiency on longer journeys. However, even on the highway, aerodynamics work against the Yukon XL, reminding drivers of its substantial size and imposing presence.

Annual fuel cost

The EPA estimates an annual fuel cost of $2,750 for this particular Yukon XL configuration. This figure is calculated based on driving 15,000 miles per year, using the EPA’s combined MPG rating, and assuming national average fuel prices. Individual fuel costs can vary significantly based on local fuel prices, driving habits, and the amount of time spent driving in the city versus on the highway. It’s important to remember that $2,750 is just an estimate; your real-world expenses could easily be higher, particularly if you frequently use the Yukon XL for towing or spend the majority of your miles in congested areas.

Real-world expectations

While the EPA provides a baseline, real-world fuel economy often differs. Yukon XL owners report numbers slightly below the EPA estimates, especially those who live in hilly areas or frequently tow. Aggressive driving habits, such as rapid acceleration and hard braking, will further reduce fuel economy.

The weight of passengers and cargo also impacts efficiency, so fully loaded vehicles will see a drop in MPG. Considering this vehicle’s role as a family hauler and occasional tow rig, it’s safe to assume that many owners will experience fuel economy below the official figures.

How it compares

Compared to other large SUVs, the 2022 GMC Yukon XL 4WD 5.3L V8’s fuel economy is generally in line with its competitors. For example, the Ford Expedition Max with its 3.5L EcoBoost V6 is rated at 17 MPG combined with 4WD, making it slightly more efficient. The Chevrolet Suburban, mechanically similar to the Yukon XL, shares the same EPA ratings. The Nissan Armada, with its 5.6L V8, achieves a combined 15 MPG with 4WD. These differences, while present, are unlikely to be a deciding factor for most buyers in this segment. They’re looking for space, capability, and features, and are willing to accept the fuel consumption trade-off.

For drivers considering other options, such as the two-wheel drive models or diesel powered models, be sure to check all Gmc fuel economy data. You can also view YUKON MPG across all years.

Tips to maximize efficiency

Gentle acceleration and braking are critical for maximizing fuel economy in the Yukon XL. Avoid aggressive driving habits, such as rapid acceleration from stoplights or abrupt braking maneuvers. These actions waste fuel and can significantly reduce your MPG. This is amplified due to the sheer mass of the vehicle.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Check your tire pressure regularly and inflate them to the recommended levels, which can be found on the sticker inside the driver’s side doorjamb.

Reduce unnecessary weight. Carrying excessive weight in the vehicle puts additional strain on the engine, diminishing fuel efficiency. Remove any unnecessary items from the cargo area and passenger compartment to lighten the load. This can be a major factor considering how much the XL can carry.

Consider using cruise control on the highway. Cruise control helps maintain a consistent speed, minimizing unnecessary acceleration and deceleration. This can improve fuel economy, especially on long highway drives. However, avoid using cruise control in hilly terrain, where it can cause the transmission to shift frequently, negating some of the benefits.

Minimize idling. Idling consumes fuel without moving the vehicle. If you’re stopped for more than a minute, turn off the engine. Modern engines are designed to restart quickly and efficiently, so you won’t waste excessive fuel by turning the engine off and on.
