The 2015 Chevrolet Silverado K15 4WD with the 6.2L V8 gets 17 MPG combined. This figure isn’t going to win any awards for saving gas, but buyers of this configuration usually prioritize strong power and capability. This truck is for those who want towing capacity, quick acceleration, and the confidence of four-wheel drive over saving on fuel. It’s a tool, not a fuel sipper.

City and highway performance

The EPA estimates the Silverado 6.2L 4WD gets 15 MPG in the city and 21 MPG on the highway. These figures show a truck that’s less efficient in stop-and-go traffic, where the large engine and four-wheel-drive work harder. However, on the open road, fuel economy improves as the engine cruises more efficiently. The 8-speed automatic transmission helps optimize engine speed for both power and fuel economy, but the Silverado’s size and weight, along with the demands of the V8, mean that fuel efficiency is a lower priority.

Annual fuel cost

The EPA estimates the annual fuel cost for this Silverado at $2,600. This is based on driving 15,000 miles per year, with 45% in the city and 55% on the highway, using national average fuel prices. It’s a large cost, reflecting the truck’s thirst for gasoline. Buyers should consider this expense as part of their overall ownership costs. This is something to consider when building a budget.

Real-world expectations

While the EPA provides a standard, real-world fuel economy can change based on driving, terrain, and load. Drivers who often tow heavy loads or drive off-road can expect lower MPG than the EPA estimates. On the other hand, those who mainly commute on relatively flat highways may get slightly better fuel economy. Hard acceleration and high speeds will also hurt fuel efficiency. The 17 MPG combined figure is a best-case scenario under controlled conditions. Your mileage will vary.

How it compares

Compared to other full-size trucks in 2015, the Silverado’s 6.2L 4WD fuel economy is similar to expectations for its performance. The Ford F-150 with the 3.5L EcoBoost V6 (also a popular choice) got around 17 MPG combined in 4×4 configuration, though some models were slightly better. The Ram 1500 with the 5.7L Hemi V8 and 4×4 also got around 17 MPG combined, meaning all three were about the same. However, a Silverado with the 5.3L V8 can provide better MPG. Buyers weighing raw power against running costs may choose a less powerful V8 engine for a slightly better MPG. You can view all Chevrolet fuel economy data on our site.

Tips to Maximize Efficiency

Lighten the load. The Silverado 6.2L is built to haul, but carrying extra weight cuts fuel economy. Remove any tools, equipment, or other items from the bed when not needed. Extra weight can change MPG, especially in city driving where the engine works harder to accelerate.

Drive smoothly. Avoid rapid acceleration and hard braking. The 6.2L V8 is responsive, but unnecessary power will quickly deplete fuel. Anticipate traffic and keep a steady speed when you can. Using cruise control on the highway can maintain a consistent pace and optimize fuel efficiency.

Maintain proper tire pressure. Underinflated tires increase rolling resistance, forcing the engine to work harder. Check your tires regularly and inflate them to the recommended pressure on the door. Proper tire inflation can improve fuel economy by as much as 3%, a small improvement over time.

Keep the engine well-maintained. Regular oil changes, air filter replacements, and spark plug maintenance ensure the engine runs well. A neglected engine is more likely to have performance issues that hurt fuel economy. Sticking to the maintenance schedule is a good way to keep your Silverado running smoothly. Check SILVERADO MPG across all years to see if different model years can offer you improvements to your fuel economy.
