26 MPG combined is a significant achievement for a full-size, two-wheel-drive truck. The 2025 Chevrolet Silverado 2WD with the 3.0L Duramax diesel is ideal for buyers who need a truck bed and reasonable running costs, offering a blend of capability and efficiency. Contractors hauling lighter loads, weekenders towing small boats, or anyone who appreciates the Silverado’s reliable build quality and passenger space but doesn’t need four-wheel drive will appreciate this particular configuration.

City and highway performance

The EPA estimates the Silverado 2WD 3.0L achieves 23 MPG in the city and 29 MPG on the highway. The city figure reflects urban driving, where the truck’s mass and the engine’s inertia affect mileage. However, the highway number is excellent. Here, the Duramax diesel and the 10-speed automatic transmission work together, allowing the engine to cruise at lower RPMs, maximizing fuel efficiency. The high MPG also indicates the Silverado’s excellent aerodynamics, which are class-leading.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2025 Chevrolet Silverado 2WD 3.0L is $2,150. This is based on driving 15,000 miles per year and using national average fuel prices. Your actual fuel costs will vary depending on your driving habits, the type of driving you do, and local fuel prices. $2,150 provides a useful benchmark for comparing the Silverado’s running costs with those of other vehicles. Diesel prices tend to fluctuate more than gasoline, so monitor fuel costs in your area to accurately project expenses.

Real-world expectations

While EPA estimates provide a standardized benchmark, real-world fuel economy can differ. Expect mileage close to the EPA figures if you practice smooth acceleration and consistent highway speeds. Towing, hauling heavy loads, or frequent aggressive driving will significantly reduce fuel economy. The Silverado’s trip computer may not always line up perfectly with hand-calculated figures, so tracking your fuel consumption manually over several tankfuls offers the most accurate picture of your personal mileage.

How it compares

Compared to other full-size trucks, the Silverado 2WD 3.0L performs remarkably well. For instance, a Ford F-150 2WD with the 2.7L EcoBoost V6 is rated at 22 MPG combined, and the RAM 1500 2WD with the 3.6L eTorque V6 achieves 23 MPG combined. Even the lighter Toyota Tundra manages only 21 MPG combined, see SILVERADO MPG across all years to see how this compares. These figures highlight the Silverado’s diesel advantage for those prioritizing fuel efficiency. The trade-off is the higher initial cost of the diesel engine and potentially higher maintenance costs. The Silverado’s efficiency is relevant for buyers considering long-term ownership or those who rack up high mileage. Smart buyers will want to compare all Chevrolet fuel economy data when making a decision.

Tips to maximize efficiency

Gentle acceleration is best. The Duramax is a torque monster, so ease onto the throttle from a stop and let the engine’s inherent pulling power do its work. Avoid aggressive starts and stops, which waste fuel and put unnecessary strain on the drivetrain. The 10-speed automatic shifts smoothly through its gears.

Maintain proper tire inflation. Underinflated tires increase rolling resistance, forcing the engine to work harder and reducing fuel economy. Check your tire pressures regularly, at least once a month, and inflate them to the pressures specified on the door jamb sticker. This is especially important when towing or hauling, as tire pressure requirements may change.

Reduce unnecessary weight. The less weight the Silverado carries, the less fuel it will consume. Remove any unnecessary items from the bed and cabin, such as tools, equipment, or cargo that isn’t needed for the current trip. Even small amounts of weight can add up over time, especially in city driving.

Use cruise control on the highway. Cruise control maintains a consistent speed, which helps to optimize fuel economy. Avoid frequent changes in speed, which can trigger the engine to downshift and consume more fuel. Anticipate traffic conditions and adjust your speed gradually to maintain a quiet and efficient driving style.

Consider using the Silverado’s drive mode selector (if equipped) to prioritize fuel efficiency. Some models offer an “Eco” or “Tow/Haul” mode (when towing) that optimizes engine and transmission settings for improved mileage. Consult your owner’s manual for specific details on how to use these modes effectively.
