Is the Chevy 2500HD gas or diesel?
The Silverado 2500HD is available with both gasoline and diesel powertrains.
Engine options for the Silverado 2500HD
The Silverado 2500HD can be equipped with two core powertrains. Each option targets different towing and payload needs, and exact outputs can vary by model year and configuration.
Two primary engine choices power the 2500HD. The following options summarize the main traits and outputs you can expect in recent model years.
- Gasoline 6.6L V8 (L8T): Approximately 401 horsepower and 464 lb-ft of torque. This engine is generally smoother, widely available, and typically has a lower upfront cost.
- Duramax 6.6L Turbo-Diesel V8 (L5P): Approximately 445 horsepower and 910 lb-ft of torque. It provides strong low-end torque for heavy towing and hauling, but at a higher initial price and with diesel fueling considerations.
Note: exact figures vary by model year, cab configuration, drivetrain, and 4x4 versus 4x2. Always check the window sticker for your specific build.
Gasoline engine details
The gas option (6.6L V8) is commonly chosen for lighter-duty use, everyday driving, and lower upfront costs. It delivers solid performance for a heavy-duty pickup without the complexity of diesel fueling and DEF systems.
Diesel engine details
The Duramax diesel offers exceptional torque and towing capability, making it the preferred choice for frequent heavy towing, long pulls, or high payloads. Diesel fuel, DEF usage, and specific maintenance considerations apply, and fuel economy can be advantageous under heavy load conditions.
Choosing between gas and diesel
Usage patterns drive the decision. If you tow very heavy trailers or haul large payloads regularly, the diesel is typically the better option due to its higher torque and sustained pulling power. If your duties are lighter, you drive mainly for daily commuting, and you want potentially lower upfront costs and simpler fueling, the gasoline engine may be more economical.
Also consider total cost of ownership, including fuel prices in your area, maintenance intervals, resale value, and potential incentives or regulations that affect diesel use.
Maintenance and fueling considerations
Diesel engines require different fueling and maintenance routines than gasoline engines. Diesel fuel availability, DEF (diesel exhaust fluid) management, and turbo system maintenance are important factors. Gasoline engines do not require DEF and typically have broader fuel station access in many regions. Always follow the owner's manual for recommended service intervals and fluids.
Summary: The Chevy Silverado 2500HD is offered with two engine options: a gasoline 6.6L V8 and a 6.6L Duramax turbo-diesel. The diesel engine provides significantly higher torque for heavy towing and payload, while the gasoline option offers simpler fueling and potentially lower upfront costs for lighter-duty use. Verify the exact engine option on your specific model year and configuration.

Are all Chevy 2500HD diesel?
No, not all Chevy 2500 models are diesel; they come with a standard 6.6L V8 gas engine, with the 6.6L Duramax turbo-diesel V8 as an available option on all trims. Customers can choose between the two powerful engines to suit their needs.
Engine options
- Gas: The standard engine is a 6.6L V8 that produces 401 horsepower and 464 pound-feet of torque.
- Diesel: The available upgrade is a 6.6L Duramax turbo-diesel V8 that generates 470 horsepower and 975 pound-feet of torque.
Is the 2025 Silverado 2500HD gas or diesel?
The 2025 Silverado 2500 diesel engine is built for higher fuel efficiency and greater torque, particularly on long trips or while towing. Diesel engines typically achieve 20 to 25 miles per gallon in the Silverado 2500, providing 30% to 35% better fuel efficiency than the gas variant.
Is the Chevy 6.0 gas or diesel?
The Chevy 6.0L V8 is a gasoline engine, not a diesel. It is a reliable, heavy-duty engine often found in Chevy Silverado trucks and other utility vehicles. While it can also run on E85 flex fuel, its fundamental design is for gasoline.
