How many miles per gallon does a 2014 Chevy 2500hd get?

The 2014 Silverado 2500HD’s fuel economy varies by engine and drivetrain. Gasoline models with the 6.0L V8 typically average about 11–13 mpg combined, while the 6.6L Duramax diesel generally delivers around 18–20 mpg combined. Four-wheel drive and towing reduce those numbers further, and real-world mileage depends on payload, terrain, and driving style.


Understanding these numbers helps buyers and current owners gauge operating costs, but exact figures depend on the specific configuration, including cab style, bed length, and axle ratio. Below is a breakdown of typical EPA estimates and factors that influence actual mileage.


EPA estimates by engine and drivetrain


Note: EPA numbers vary with cab style, bed length, axle ratios, and whether the truck is 2WD or 4WD. The following figures reflect common configurations for the 2014 Silverado 2500HD.



  • Gasoline 6.0L V8, 2WD: approximately 11–13 mpg combined (roughly 9–11 mpg city / 14–16 mpg highway).

  • Gasoline 6.0L V8, 4WD: approximately 10–12 mpg combined (roughly 9–11 mpg city / 14–16 mpg highway).

  • Duramax 6.6L Diesel, 2WD: approximately 18–20 mpg combined (roughly 15–16 mpg city / 21–23 mpg highway).

  • Duramax 6.6L Diesel, 4WD: approximately 17–19 mpg combined (roughly 15 mpg city / 20–22 mpg highway).


Concluding: these numbers provide a general framework for expected efficiency across common configurations. Real-world mileage will vary with payload, towing, and driving conditions.


Practical considerations that affect mpg


Payload, towing weight, terrain, and driving behavior significantly influence real-world fuel economy. Highway cruising with steady speeds and proper tire inflation tends to boost efficiency, while frequent idling, aggressive acceleration, or heavy loads can sharply reduce mpg. Regular maintenance and using the recommended fuel also impact performance over time.


What to know for buyers and owners


When evaluating a 2014 2500HD, check the original EPA window sticker for the exact configuration, or use the EPA’s Fuel Economy website with the vehicle’s VIN to obtain specific estimates. Keep in mind that trucks used for towing or with heavy payloads will typically fall below the posted numbers, sometimes by several miles per gallon.


Summary: For the 2014 Chevy Silverado 2500HD, mpg depends on engine and drivetrain—gasoline 6.0L V8 around 11–13 mpg combined; Duramax diesel around 18–20 mpg combined—with 4x4 and towing typically lowering figures further. Verify configuration-specific ratings and expect real-world mileage to vary based on usage and conditions.

What year to stay away from a Chevy 2500?


Years to generally stay away from a Chevy 2500 include 2003-2006 due to electrical issues and rust, 2014-2017 for transmission, suspension, and HVAC problems, and specific models like the 2007 and 2012 for engine and brake issues, according to sources like CarGurus, MotorBiscuit, and Camera Source. The specific problems vary by model year, but common complaints across these years include transmission failures, electrical gremlins, and rust.
 
Years to avoid

  • 2003-2006: These models are frequently cited for electrical problems, build quality issues, rust, and transmission troubles. 
  • 2007: This model year is often noted for engine and transmission issues, as well as excessive oil consumption. 
  • 2012: Reported to have issues with the engine and transmission, leading to high ownership costs. 
  • 2014-2015: These early years of a new generation are known for having numerous recalls and complaints about the transmission, air conditioning, and other electrical systems. 
  • 2017: This model year is frequently singled out for significant transmission problems, including rough shifting and poor performance. 



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.
