18 MPG combined doesn’t sound impressive, but for the 2019 GMC Yukon C1500 XL 2WD with the 5.3L V8, it’s what you get for needing serious passenger and cargo space, along with truck-like towing capability in a reasonably comfortable package. This isn’t a fuel-sipping vehicle, and it’s not trying to be. It’s a tool, and its fuel economy shows that.

City and highway performance

The EPA estimates 15 MPG in the city and 22 MPG on the highway. The city figure shows what happens when moving a large, heavy vehicle through stop-and-go traffic. The 5.3L V8 has to work hard, especially from a standstill. Expect the Active Fuel Management system (cylinder deactivation) to kick in when cruising, but don’t expect it regularly within urban driving. The highway number, on the other hand, is more attainable. Long stretches of consistent speed allow the engine to settle into a more efficient rhythm, maximizing the benefits of cylinder deactivation and the 6-speed automatic transmission’s high overdrive gears.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 GMC Yukon C1500 XL 2WD 5.3L 8-cyl at $2,450. This is based on driving 15,000 miles per year and using national average fuel prices. Your fuel costs will vary depending on your driving habits, the type of driving you do (city vs. highway), and gasoline prices in your area. However, the $2,450 figure gives you a baseline for comparing the Yukon’s costs to other vehicles. It also shows the fuel needs of a large, V8-powered SUV.

Real-world expectations

While the EPA estimates give you a standardized benchmark, actual mileage can change, sometimes a lot. Things like fast acceleration, frequent towing, and even tire pressure can affect fuel consumption. Owners of the 2019 Yukon XL should monitor their fuel economy to get a good idea of their vehicle’s consumption. Don’t be surprised if you see numbers a little below the EPA estimates, especially if you drive mostly in the city or tow often. However, on long highway trips with a light load, getting or even going slightly above the EPA’s 22 MPG rating is possible.

How it compares

The Yukon XL’s fuel economy is similar to other large, body-on-frame SUVs. For example, the 2019 Chevrolet Suburban, like the Yukon XL, has the same 15 city / 22 highway MPG rating with the 5.3L engine. The Ford Expedition Max, with its turbocharged 3.5L EcoBoost V6, gets slightly better official fuel economy (17 city / 23 highway), but the real-world difference is often less. When looking at alternatives, understand the trade-offs. Smaller SUVs or crossovers will get better fuel economy, but they don’t have the Yukon XL’s space and towing. A vehicle like the Honda Pilot gets about 27 MPG on the highway, for example, but cannot offer similar utility. Those who want less gas may need to look at a different type of vehicle or browse YUKON MPG across all years. The decision comes down to balancing fuel costs with what you need the vehicle to do.

Tips to maximize efficiency

Avoid fast acceleration and braking. The Yukon XL is heavy, so changes in speed take a lot of energy. Smooth acceleration and watching traffic can improve your MPG.

Keep the tires properly inflated. Underinflated tires increase rolling resistance, making the engine work harder. Check your tire pressure regularly (look at the sticker on the driver’s side doorjamb) and inflate them properly.

Use cruise control on the highway. Keeping a consistent speed reduces acceleration and deceleration, which can improve fuel economy on long trips. Watch the terrain and adjust your speed; cruise control isn’t always best on hilly roads.

Don’t carry extra weight. Too much cargo adds to the vehicle’s weight, hurting fuel efficiency. Remove anything you don’t need regularly. A lighter vehicle burns less fuel.

Think about using premium fuel when towing. While the 5.3L engine can use regular gasoline, premium fuel when towing heavy loads can improve fuel economy and performance by reducing engine knock. Consider the cost before switching.
