18 MPG combined. That’s the EPA’s fuel economy estimate for the 2025 Chevrolet Silverado 4WD equipped with the 2.7L turbocharged four-cylinder engine. It’s a number that most Silverado buyers will accept: these buyers prioritize capability, a usable bed, and the confidence of four-wheel drive over saving on gas. They’re willing to make compromises for truck functionality, but that doesn’t mean they don’t care about efficiency.

City and highway performance

The EPA estimates the Silverado’s fuel economy at 17 MPG in the city and 20 MPG on the highway. The small difference highlights the engine’s tuning for consistent power across various driving conditions. The 2.7L turbo is less sensitive to stop-and-go traffic than larger engines. While 20 MPG on the highway is achievable, keeping it there requires a light foot and consistent speeds. Frequent acceleration and aggressive passing will quickly diminish fuel economy.

Annual fuel cost

The EPA estimates the annual fuel cost for this Silverado configuration is $2,450. This figure is based on driving 15,000 miles per year and using national average fuel prices. It’s a useful benchmark, but individual fuel costs will vary depending on driving habits, local fuel prices, and the type of gasoline used. The engine runs best on regular unleaded, but consistent towing or heavy hauling might be better with premium fuel, changing the annual fuel bill. The $2,450 is an estimate, and your real-world expenses will likely differ.

Real-world expectations

Official numbers provide a baseline, but real-world fuel economy changes. Expect to see figures slightly below the EPA estimates, particularly if you regularly use the Silverado as intended. Towing significantly impacts fuel consumption, often dropping mileage to the low teens. Hauling heavy loads in the bed also decreases efficiency. Even daily commutes with frequent traffic jams will likely result in lower MPG than the official city estimate. The Silverado’s weight and aerodynamics will always affect numbers, even with an efficient engine.

How it compares

The Silverado’s fuel economy must be considered against its competitors. A comparable Ford F-150 4×4 with the 2.7L EcoBoost V6 earns an EPA-estimated 20 MPG combined. Ram’s 1500 4×4 with the 3.6L eTorque V6 achieves around 19 MPG. These figures show that the Silverado’s 2.7L turbo-four isn’t a class leader in fuel economy, but it remains competitive among half-ton, four-wheel-drive trucks. The Silverado’s advantage is the engine’s strong low-end torque and proven reliability give it a distinct appeal. Buyers often trade a small fuel economy difference for the perceived confidence of Chevy’s powertrain engineering. Potential buyers can review SILVERADO MPG across all years for additional perspective.

Buyers cross-shopping the GMC Sierra 1500 4×4 (the mechanically similar sibling to the Silverado) will see nearly identical fuel economy figures with the 2.7L turbo engine. But opting for the larger 5.3L V8 in either truck will drop the combined fuel economy to 16-17 MPG, making the turbo-four a good choice for buyers who do not need V8 power.

Tips to maximize efficiency

Consistent maintenance is important. Ensure that the Silverado’s tires are properly inflated. Underinflated tires increase rolling resistance, which reduces fuel economy. Regularly service the engine according to Chevrolet’s recommended maintenance schedule, including oil changes and air filter replacements. A well-maintained engine operates more efficiently.

Smooth acceleration and braking techniques are important. Avoid aggressive throttle inputs and hard braking. Anticipate traffic flow and maintain a consistent speed whenever possible. The 8-speed automatic transmission is programmed for efficiency, but it relies on the driver’s behavior to achieve the best results.

Reduce unnecessary weight. Remove any cargo or equipment that isn’t essential. Extra weight increases the engine’s workload, decreasing fuel economy. This is especially true when driving in the city where frequent stops and starts magnify the effect of added weight.

Consider the impact of aftermarket modifications. Lift kits, oversized tires, and roof racks can all negatively influence fuel economy. These modifications increase aerodynamic drag and rolling resistance. While they enhance the Silverado’s appearance and off-road capability, they reduce efficiency. Remove your roof rack when not in use to save fuel.

Use cruise control carefully. On flat, open highways, cruise control can maintain a consistent speed, improving fuel economy. But, in hilly terrain, it can sometimes lead to unnecessary downshifts and increased fuel consumption. Monitor your instantaneous MPG display and adjust your speed accordingly.
