How many miles per gallon does a 2024 2500HD Duramax get?
Typically, the 2024 Silverado 2500HD with the Duramax diesel delivers roughly 16–17 mpg combined, with 2WD models usually near 17 mpg and 4x4 models around 16 mpg, depending on cab/bed configuration and tires.
The question is influenced by how EPA tests diesel-heavy heavy-duty pickups and by how owners use them. Because this vehicle is built for towing and payload, MPG can swing widely based on load, terrain, and driving style. This article breaks down official EPA estimates by setup, explains what you can expect in the real world, and offers practical tips to improve efficiency.
EPA estimates for the 2024 Silverado 2500HD Duramax
EPA estimates vary by drivetrain and body style. The following figures reflect common setups as published by the EPA.
- 2WD Duramax: 15 mpg city / 20 mpg highway / 17 mpg combined
- 4x4 Duramax: 14 mpg city / 19 mpg highway / 16 mpg combined
Note that exact figures depend on cab style, bed length and axle ratio. Real-world mileage typically falls within a point or two of these numbers, and can be lower during heavy towing or when the truck is fully loaded.
Real-world mileage and factors that influence it
Beyond the EPA labels, several variables influence on-road efficiency. Here are the primary factors that can push mileage above or below the EPA estimates.
- Payload and towing: Heavier loads increase engine work and reduce mpg, especially on climbs or in hot weather.
- Terrain and driving conditions: Stop-and-go city driving reduces mpg; steady highway speeds improve mpg.
- Tire size and inflation: Underinflated or oversized tires raise rolling resistance and lower mpg.
- Drivetrain and gearing: Four-wheel drive adds weight and friction, typically lowering mpg by a small margin compared with 2WD.
- Maintenance and fuel quality: A clogged air filter, dirty injectors, or poor-quality fuel can reduce efficiency.
- Driving style: Aggressive acceleration and high speeds cut mpg; smoother, gradual acceleration helps.
- Weather and altitude: Cold weather and higher altitude can decrease mpg.
In real-world use, many drivers report mpg in the mid-teens to upper-teens, with lower numbers when towing or hauling and higher numbers in light-duty, highway-only scenarios.
Tips to maximize fuel economy
To improve efficiency when using the 2024 Silverado 2500HD Duramax for daily driving or work, consider these practical steps.
- Limit payload and avoid unnecessary heavy hauling when possible.
- Drive smoothly: accelerate gradually, anticipate traffic, and use cruise control on highways.
- Keep tires properly inflated to the manufacturer’s recommended pressure; rotate and align as needed.
- Maintain the truck: replace air filters, keep the engine tuned, and use the recommended fuel quality.
- Plan trips to minimize idling and choose routes with steadier speeds when feasible.
- Use efficient towing practices and weight distribution to reduce drag when pulling a trailer or heavy load.
Even with a capable diesel, mindful loading, maintenance, and driving habits can help you approach the EPA estimates more consistently.
Summary
The 2024 Silverado 2500HD Duramax typically delivers about 16–17 mpg combined, with 2WD configurations closer to 17 mpg and 4x4 configurations around 16 mpg. EPA estimates vary by cab/bed setup and axle choices, and real-world mileage is highly influenced by payload, towing, terrain, and driving style. By maintaining the vehicle and adopting efficient driving habits, you can maximize fuel economy within the truck’s heavy-duty design limits.
