The 2024 GMC Yukon 2WD equipped with the 3.0L Duramax diesel gets a combined 23 MPG, which isn’t going to win any hypermiling awards. However, it’s a good choice for buyers who need passenger and cargo capacity without completely sacrificing fuel efficiency. This Yukon configuration is good for families who regularly haul kids, pets, and gear, those who want a comfortable ride on long road trips, and individuals who like the Yukon’s bold styling. Those buyers will find the Duramax offers respectable MPG for a large SUV.

City and highway performance

The EPA estimates the 2024 GMC Yukon 2WD 3.0L achieves 21 MPG in the city and 27 MPG on the highway. The city rating is respectable, reflecting the diesel engine’s efficiency at lower speeds and the 10-speed automatic transmission’s ability to keep the engine in its sweet spot. The highway figure is where this Yukon shines, allowing for extended cruising range between fill-ups; this is a major benefit for cross-country family adventures. The 27 MPG figure is achievable in real-world driving if you resist the urge to accelerate quickly. The combination of these two figures results in a solid combined MPG rating.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2024 GMC Yukon 2WD 3.0L diesel at exactly $2,400. This figure is based on driving 15,000 miles per year and using national average fuel prices. Remember that this is just an estimate, and your actual fuel costs may vary depending on your driving habits, the type of driving you do (city versus highway), and local diesel prices. Still, $2,400 provides a useful benchmark for comparing the Yukon’s fuel expenses against other large SUVs under consideration.

Real-world expectations

EPA estimates provide a good baseline, but real-world fuel economy will always vary. Factors such as driving style, terrain, weather conditions, and cargo weight can all impact how many miles you get per gallon. Drivers who accelerate quickly or who frequently tow will likely see lower numbers than the EPA estimates.

However, those who prioritize smooth acceleration, maintain a steady speed on the highway, and avoid unnecessary idling may exceed the EPA figures. Owners report that highway trips taken at legal speeds often yield MPG figures at or slightly above the EPA rating, making the diesel a good choice for trips.

How it compares

The 2024 GMC Yukon 2WD 3.0L Duramax offers good fuel economy when compared to its competitors. The Chevrolet Tahoe, mechanically similar, also achieves 23 MPG combined with its Duramax diesel in 2WD configuration. Comparing it to others shows its fuel-sipping benefits in this class. For example, the Ford Expedition with its EcoBoost V6 typically lands in the 17-19 MPG combined range. Even the Toyota Sequoia, despite its hybrid powertrain, often struggles to match the Yukon’s highway MPG. For those who need a large SUV, understanding all Gmc fuel economy data is important. The four-wheel-drive version of the Yukon 3.0L Duramax, while offering better capability, typically sees a slight decrease in MPG, making the 2WD version the better choice for those wanting efficiency. It is also crucial to explore YUKON MPG across all years to get a view of its long-term economy.

Tips to maximize efficiency

The 3.0L Duramax diesel responds well to a careful driving style. Avoid accelerating quickly and braking hard, as these actions consume extra fuel. Anticipate traffic flow and maintain a steady speed when possible. Every time you accelerate harshly, you’re effectively dumping fuel into the engine, reducing your overall MPG.

Correct tire inflation is important for fuel economy. Check your tire pressure regularly and make sure it matches the recommended level listed on the driver’s side doorjamb. Underinflated tires create more rolling resistance, forcing the engine to work harder and burn more fuel.

Minimize idling when possible. If you’re stopped for more than a minute, turn off the engine. Modern diesel engines are designed to restart quickly and efficiently, and the fuel saved from avoiding extended idling can add up over time.

Reduce aerodynamic drag by removing unnecessary items from the roof rack or cargo carrier. These accessories create wind resistance, impacting fuel efficiency, particularly at higher speeds. If you don’t need it up there, take it down.

While the temptation to upgrade wheels and tires is strong, remember that larger, heavier wheels and tires can negatively impact fuel economy. Sticking with the factory-specified wheel and tire size will help maintain optimal MPG. Also, consider low-rolling resistance tires when it’s time for a replacement set.
