The 2022 GMC Yukon XL 4WD with the 3.0L Duramax diesel achieves a combined EPA fuel economy rating of 22 MPG. That’s a surprisingly respectable figure, especially when you consider that this is a truly enormous SUV, one that prioritizes passenger and cargo space over outright efficiency. This isn’t a vehicle for solo commutes, it’s designed to haul families, their gear, and potentially a trailer, all while providing a comfortable and capable driving experience.

City and highway performance

The EPA breaks down the 22 MPG combined rating into 20 MPG in the city and 26 MPG on the highway. While 20 MPG in city driving is acceptable for a vehicle of this size and weight, it’s the 26 MPG highway figure that really stands out. This relatively high number makes the diesel Yukon XL a good choice for families who frequently embark on long road trips. The combination of comfortable cruising and fewer fuel stops compared to its gasoline-powered counterparts adds real-world value.

Annual fuel cost

According to the EPA, the estimated annual fuel cost for the 2022 GMC Yukon XL 4WD 3.0L diesel is $2,550. This calculation assumes 15,000 miles of driving per year and uses the national average fuel price. Actual fuel costs will vary depending on individual driving habits, local fuel prices, and the percentage of city versus highway driving. While it may seem high at first glance, consider the size and capability of this vehicle, plus the fact that its gasoline counterparts can easily exceed this figure. and understanding all Gmc fuel economy data can help assess the overall efficiency of the brand’s lineup.

Real-world expectations

While the EPA estimates provide a useful baseline, real-world fuel economy can vary. Drivers who frequently tow trailers or consistently drive aggressively can expect figures to be lower than the official ratings. But those who prioritize smooth acceleration and maintain consistent highway speeds may see numbers closer to or even slightly above the EPA’s estimates. The onboard fuel economy display can provide immediate feedback on driving habits and help drivers optimize their fuel efficiency. Individual results always vary for YUKON MPG across all years.

How it compares

The GMC Yukon XL’s diesel fuel economy sets it apart from many of its competitors. The gasoline-powered Yukon XL with the 5.3L V8, for example, manages just 16 MPG combined with 4WD. Even the smaller Cadillac Escalade, sharing the same platform, lags behind with the base 6.2L V8, coming in at 16 MPG combined on 4WD models. The Ford Expedition Max, equipped with its EcoBoost V6, comes closest, achieving an EPA-estimated 19 MPG combined with 4WD. However, it sacrifices some of the Yukon XL’s cargo space and towing capability. For buyers prioritizing fuel efficiency in a large SUV, the Yukon XL diesel presents an advantage, particularly compared to the thirsty V8s often found in this segment. It also offers more space and towing compared to the Ford Expedition Max.

Tips to maximize efficiency

One of the easiest ways to improve fuel economy in the Yukon XL diesel is to drive smoothly. Avoid abrupt acceleration and braking, as these actions consume more fuel. Anticipate traffic flow and maintain a steady speed whenever possible. Using cruise control on the highway can help maintain a consistent pace and minimize fuel consumption.

Keep your tires properly inflated to the recommended pressure, which is typically found on a sticker inside the driver’s side doorjamb. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel economy. Regularly check tire pressure, especially during periods of temperature fluctuations.

Reduce unnecessary weight in the vehicle. Excess cargo adds to the overall weight of the SUV, which negatively impacts fuel efficiency. Remove any items that are not essential for your journey, such as sporting equipment or tools that are rarely used. Even seemingly small items can add up and affect fuel consumption.

Consider using the Yukon XL’s drive mode selector to optimize fuel efficiency. The “Normal” or “Auto” mode is typically the most efficient for everyday driving. Avoid using the “Sport” mode unless necessary, as it prioritizes performance over fuel economy. Depending on the configuration, the Yukon XL may have a specific “Eco” mode designed to maximize fuel efficiency.

Proper maintenance is important to maintain optimal fuel economy. Ensure that the engine air filter is clean, as a dirty filter restricts airflow and reduces engine efficiency. Follow the manufacturer’s recommended service schedule for oil changes, tune-ups, and other maintenance tasks. A well-maintained engine will run more efficiently and consume less fuel.
