17 MPG combined is what you get for the 2023 GMC Yukon XL 2WD with the 5.3L V8. Nobody buys this Yukon expecting Prius-like efficiency. This extended-length SUV is about moving families, hauling serious cargo, and projecting a certain image. Fuel economy is a secondary concern, but understanding the costs involved is important.

City and highway performance

The EPA estimates that the Yukon XL 2WD 5.3L achieves 15 MPG in the city and 20 MPG on the highway. These figures reflect the realities of moving a vehicle of this size and weight. Around town, the constant stop-and-go driving forces the engine to work harder, hence the lower MPG number. On the open road, the 10-speed automatic transmission allows the engine to settle into a more efficient cruising RPM, resulting in the slightly better 20 MPG rating. Drivers should note that aggressive acceleration will significantly impact these figures, and that towing will drastically reduce fuel economy on both city streets and the highway.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2023 GMC Yukon XL 2WD 5.3L is $2,600. This figure is based on driving 15,000 miles per year and using national average fuel prices. Remember that this is just an estimate. Your actual fuel costs will vary depending on your driving habits, the type of fuel you use, and, most importantly, local fuel prices. If you primarily drive in the city or have a heavy foot, expect to exceed this $2,600 estimate. Current fuel prices are always in flux, so the annual cost can easily be higher or lower depending on how much the market fluctuates.

Real-world expectations

While the EPA provides a standardized benchmark, real-world MPG often differs. Yukon XL owners often report fuel economy figures slightly below the EPA estimates, especially in mixed driving conditions. Factors like traffic congestion, weather, and the use of accessories like air conditioning can all negatively impact fuel consumption. It’s not uncommon to see combined MPG figures closer to 15 or 16 MPG in everyday use. Careful drivers may be able to achieve the EPA numbers, but realistically, most owners should anticipate slightly lower efficiency.

How it compares

The Yukon XL’s fuel economy is generally in line with other full-size, extended-length SUVs with similar powertrains. The Chevrolet Suburban, essentially the Yukon XL’s corporate cousin, delivers comparable MPG figures with its 5.3L V8. The Ford Expedition Max with its 3.5L EcoBoost V6 offers slightly better combined fuel economy, often hovering around 19 MPG, primarily due to Ford’s turbocharging technology. However, even the Expedition Max struggles to break the 20 MPG barrier in real-world mixed driving. The Nissan Armada, with its naturally aspirated 5.6L V8, typically lags behind the Yukon XL in fuel efficiency. These MPG differences matter to some buyers, but purchase decisions are heavily influenced by brand loyalty, features, and overall capability.

Tips to maximize efficiency

Gentle acceleration and braking are critical. The Yukon XL is a heavy vehicle, and rapid acceleration burns significantly more fuel. Anticipate traffic flow and avoid abrupt stops whenever possible. Smooth, gradual transitions will minimize fuel consumption.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder to maintain speed. Check your tire pressure regularly and inflate them to the manufacturer’s recommended specifications, typically found on a sticker inside the driver’s side doorjamb.

Minimize idling. Letting the engine idle for extended periods wastes fuel. If you’re stopped for more than a minute, it’s generally more fuel-efficient to turn off the engine. Modern engine start/stop systems can help with this, but the Yukon XL 5.3L does not offer automatic stop-start, so manual intervention is required.

Use cruise control on the highway. Cruise control helps maintain a consistent speed, which optimizes fuel efficiency. By avoiding fluctuations in speed, you can reduce unnecessary fuel consumption, achieving efficiency closer to the EPA’s highway estimate.

Reduce unnecessary weight. Carrying excessive cargo adds weight to the vehicle, which increases fuel consumption. Remove any unnecessary items from the vehicle to improve fuel economy. Even small amounts of weight can add up and make a noticeable difference over time.

The Yukon XL 2WD 5.3L fulfills a specific need: large-capacity transport with traditional V8 power. Its owners prioritize space, towing ability, and ride comfort over better fuel efficiency. They understand and accept the trade-offs.
