How many miles per gallon does a 2022 Silverado 2500 HD get?

The 2022 Chevrolet Silverado 2500 HD, a heavy-duty pickup truck, has an average fuel economy of 16 miles per gallon (mpg) in combined city and highway driving. This figure is based on the Environmental Protection Agency's (EPA) estimates for the Silverado 2500 HD with the standard 6.6-liter V8 gasoline engine and rear-wheel drive configuration.

Fuel Economy Breakdown

The EPA estimates the 2022 Silverado 2500 HD with the 6.6-liter V8 gasoline engine and rear-wheel drive to have the following fuel economy ratings:

• City: 15 mpg


• Highway: 18 mpg


• Combined: 16 mpg

It's important to note that actual fuel economy may vary depending on driving conditions, driving habits, and other factors.

Factors Affecting Fuel Economy

The fuel economy of the Silverado 2500 HD can be influenced by several factors, including:

• Engine and Drivetrain Configuration: The Silverado 2500 HD is available with a 6.6-liter V8 gasoline engine or a 6.6-liter V8 Duramax diesel engine, both of which have different fuel economy ratings. The choice of rear-wheel drive or four-wheel drive can also impact fuel efficiency.


• Payload and Towing Capacity: As a heavy-duty pickup, the Silverado 2500 HD is designed to haul heavy loads and tow large trailers. The weight of the payload and the trailer being towed can significantly affect the vehicle's fuel economy.


• Driving Conditions: Factors such as terrain, weather, and traffic can all influence the Silverado 2500 HD's fuel efficiency. For example, driving in stop-and-go city traffic or on steep inclines can reduce fuel economy compared to highway driving.


• Driving Habits: The way the driver operates the vehicle, such as aggressive acceleration, high-speed driving, and frequent braking, can also impact the Silverado 2500 HD's fuel economy.

It's important to keep these factors in mind when evaluating the fuel economy of the 2022 Silverado 2500 HD and to adjust your driving style and expectations accordingly.

How many miles per gallon does a 6.7 F-250 diesel get?

A Ford F-250 with the 6.7L diesel engine typically gets 18-20 mpg on the highway and 15-18 mpg in mixed city/highway driving when unloaded. Fuel economy drops significantly when towing, with estimates ranging from 8.9 to 12-15 mpg depending on the load. Real-world mileage is affected by driving style, speed, terrain, and other factors. 
Unloaded driving

• Highway: Expect around 18-20 mpg on the highway under optimal conditions. Some drivers report getting as high as 24 mpg on highways, particularly with the high-output (HO) engine and gentle driving. 
• Mixed/City: You can expect a combined average of 15-18 mpg. 
• Factors: Driving speed has a significant impact. Driving at 80 mph can reduce fuel economy compared to driving at 60-65 mph, where you might see higher mileage.

Towing

• Towing MPG: When towing, fuel economy can drop to 12-15 mpg. 
• Heavier loads: With very heavy loads (e.g., a 17,000 lb 5th wheel), mileage can drop to under 9 mpg.

Other considerations

• High-output (HO) engine: The high-output version of the 6.7L engine offers more power with little to no difference in fuel consumption compared to the standard engine under normal conditions. 
• Engine break-in: New engines may have lower fuel economy until they are broken in. 
• DPF delete: Aftermarket modifications like a DPF delete may increase MPG, but this is not recommended for street use. 

How many miles per gallon does a Chevy Silverado 2500 HD get?

The Silverado 2500 HD's MPG varies by model year and engine, with recent models averaging 13-14 mpg in the city and 17-18 mpg on the highway for the gas engine. The Duramax diesel engine typically gets around 17 mpg in the city and 23 mpg on the highway in the 2025 model year. For both, towing significantly reduces fuel economy.

Estimated MPG by engine and model year 

• 2025 Duramax Diesel:
  • City: Approximately 17 mpg 
  • Highway: Approximately 23 mpg 
• 2024 & 2025 Gas Engine (general estimates):
  • City: 13-14 mpg 
  • Highway: 17-18 mpg 

Factors that affect MPG

• Engine: Diesel engines are generally more fuel-efficient than gasoline engines. 
• Trim Level: Higher trims like LTZ and High Country may have slightly lower MPG compared to base models like Work Truck or Custom. 
• Towing and Hauling: Towing a load, especially heavy loads, will substantially decrease fuel economy, potentially bringing it down to 9-12 mpg. 
• Driving Conditions: Your specific driving habits, terrain, and how much cargo you carry will impact your real-world MPG. 

How many miles per gallon does a 2022 Chevy Silverado 2500 HD get?

The 2022 Chevy 2500HD with the 6.6L gas engine gets approximately 12 mpg city / 14 mpg highway, though real-world mileage varies depending on driving conditions. Factors like driving style, towing, and terrain can affect these numbers, with some owners reporting higher or lower averages. 

• Official EPA estimates: There are no official EPA estimates for the Silverado 2500HD, so ratings are based on independent tests. 
• Real-world city: Around 12 mpg, but can drop lower when carrying tools or towing. 
• Real-world highway: Around 14 mpg, but can fluctuate. 
• Factors influencing mileage: Fuel economy is heavily dependent on driving habits, whether the truck is towing or hauling, and the terrain. Some drivers report figures like 15-18 mpg on the highway or around 15 mpg combined for the gas engine. 

What fuel mileage does a 6.6 l Duramax diesel get?

The 6.6L Duramax engine's MPG varies, but typically ranges from 15-18 MPG for mixed driving and 17-20 MPG for unloaded highway driving. Actual mileage depends heavily on factors like driving conditions, towing, and the specific model year. Some newer models achieve higher efficiency, with a 2025 Silverado HD hitting 20.4 MPG on a controlled highway loop.

• Mixed/City: Around 15 MPG or lower, especially with stop-and-go traffic. 
• Highway (unloaded): Typically 17-20 MPG, but can vary with speed. 
• Towing: Expect significantly lower mileage, often in the 10-14 MPG range depending on the load and terrain. 

Factors that influence MPG:

• Towing and load: Hauling heavy loads reduces fuel efficiency. 
• Driving conditions: Hilly terrain or stop-and-go city traffic lowers MPG. 
• Vehicle age and break-in: Newer trucks may improve after an initial break-in period, with some owners reporting increased mileage after a few thousand miles. 
• Other factors: Speed, road conditions, and factors like the truck's emissions system (e.g., temporary DPF regen cycles) can also have an effect.
