18 MPG combined won’t excite hybrid car fans. But if you need the large passenger and cargo space of the 2015 Chevrolet Suburban C1500 2WD with the 5.3L V8, it’s an acceptable tradeoff. This isn’t a fuel-efficient vehicle. It’s bought for its hauling capability and durability, which are important to large families, construction crews, and those who regularly tow heavy loads.
City and highway performance
The EPA estimates of 16 MPG in the city and 23 MPG on the highway show where this Suburban performs best. Stop-and-go city driving, with its constant acceleration and braking, reduces fuel economy because of the vehicle’s weight. On the open road, the engine settles into a more efficient cruising speed, and the 23 MPG figure is more attainable. This reflects the Suburban’s design: powerful and capable, but not optimized for cities. The 6-speed automatic transmission helps in both situations, with gears that balance acceleration with fuel efficiency.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2015 Chevrolet Suburban C1500 2WD 5.3L V8 at $2,450. This is based on driving 15,000 miles per year, with mixed city and highway driving, and using the national average fuel price. Fuel prices change, but this $2,450 is a useful benchmark for understanding the potential cost of ownership. This figure is important to consider, especially if you plan to drive the Suburban a lot.
Real-world expectations
Consider the EPA estimates guidelines, not guarantees. Real-world fuel economy changes based on driving habits, traffic, and how you drive the Suburban. For example, regular towing reduces fuel economy significantly, potentially below the EPA figures. Aggressive driving or long idling also negatively impacts MPG. Careful driving and consistent highway miles can sometimes bring you closer to the EPA’s highway estimate.
How it compares
Compared to other large SUVs from the same time, the 2015 Suburban’s fuel economy is typical. The Ford Expedition with its 3.5L EcoBoost V6, for example, had similar fuel economy numbers, around 16 MPG city and 22 MPG highway. A similarly equipped GMC Yukon, which is related to the Suburban, had nearly identical figures. The Nissan Armada, with its larger 5.6L V8, delivered slightly worse fuel economy, around 13 MPG city and 19 MPG highway. These comparisons are important for potential buyers: if they need the space and capability these vehicles offer, they must accept the fuel economy. Owners accept this trade off because of the vehicle’s utility — the ability to tow heavy loads, easily transport large families, and handle a wide variety of tasks.

Tips to maximize efficiency
Gentle acceleration and braking are key to saving fuel in a large SUV like the Suburban. Avoid aggressive starts and hard stops. Anticipate traffic to maintain a steady speed. The 5.3L V8 delivers ample power, but using that power excessively wastes fuel.
Proper tire inflation is often overlooked, but maintaining the correct pressure can improve fuel economy. Check your tires regularly and inflate them to the pressure recommended on the doorjamb label. Underinflated tires create more rolling resistance, increasing fuel consumption.
Minimize idling, especially in city driving. The Suburban’s large engine consumes a lot of fuel even when stationary. If you expect to be stopped for more than a minute, turn off the engine. Restarting consumes less fuel than prolonged idling.
Reduce the weight you carry. Hauling unnecessary cargo adds to the vehicle’s load and decreases fuel economy. Remove any items from the vehicle that are not essential for your daily driving. A lighter vehicle requires less energy to move.
Consider using cruise control on the highway to maintain a consistent speed. This can help optimize fuel efficiency by preventing unintentional speed fluctuations. Aim to keep your speed steady and within the legal limits for optimal results.
