How many miles per gallon does a Chevy Express 2500 get?

Gasoline-powered Chevy Express 2500 vans typically achieve mid-teens in combined miles per gallon, while the available 2.8L Duramax diesel can push into the low- to mid-20s on average. Exact figures depend on engine, drivetrain, payload, and driving conditions.


Gasoline engines


The Express 2500 offers several gasoline options. EPA ratings vary by year, engine, and configuration, but the following ranges reflect common setups for 2WD models with automatic transmissions and typical cargo loads.



  • 4.3L V6 gasoline: generally about 12–14 mpg city and 17–20 mpg highway, roughly 14–17 mpg combined.

  • 5.3L V8 gasoline: typically around 12–15 mpg city and 18–20 mpg highway, about 15–18 mpg combined.

  • 6.0L V8 gasoline: usually near 10–13 mpg city and 15–18 mpg highway, roughly 12–15 mpg combined.


Concluding this section, gasoline-powered Express 2500s deliver lower overall fuel economy compared with diesel, with wide variation based on payload, driving style, and terrain.


Diesel option


The 2.8L Duramax diesel offers a different efficiency profile, especially on longer highway runs or when pulling loads. The following ranges cover typical 2WD configurations with automatic transmissions.



  • 2.8L Duramax diesel: about 18–23 mpg city and 25–28 mpg highway, roughly 21–25 mpg combined.


Concluding this section, the diesel option tends to improve highway fuel economy substantially, though real-world results depend on payload, aerodynamics, and maintenance.


Factors that affect mpg


Several variables can shift actual fuel economy for a Chevy Express 2500, including payload weight, driving conditions, climate, tire pressure, and driving behavior. Heavier loads and stop-and-go city driving typically reduce mpg, while steady highway cruising with proper maintenance helps conserve fuel.


How to verify exact numbers for your vehicle


For precise figures tailored to a specific year, engine, and axle ratio, consult fueleconomy.gov or your vehicle’s window sticker. Real-world tests and owner reviews can also provide practical benchmarks beyond official estimates.


Ways to maximize mpg


Tips to improve efficiency include maintaining proper tire inflation, performing routine maintenance, reducing unnecessary weight, using the most economical drive mode if available, and planning routes to minimize idling and congestion.


Summary


The Chevy Express 2500’s fuel economy depends heavily on the chosen powertrain. Gasoline options commonly yield roughly 12–15 mpg city and 17–20 mpg highway (about 14–18 mpg combined), while the 2.8L Duramax diesel generally provides higher efficiency, with combined figures in the low-to-mid 20s and highway numbers near 25–28 mpg. Always refer to EPA estimates for your exact year and configuration and consider real-world factors such as payload and driving habits when evaluating mpg expectations.

How many miles per gallon does a 6.0 Express get?


The Chevy Express with a 6.0L V8 engine gets approximately 13 mpg combined, with EPA estimates of around 11 mpg in the city and 16 mpg on the highway. Real-world mileage can vary, with some owners reporting around 12 mpg combined, especially when the vehicle is loaded, while others achieve closer to 14–17 mpg on the highway. 
Estimated vs. real-world MPG

  • EPA Combined: 13 mpg
  • EPA City: 11 mpg
  • EPA Highway: 16 mpg
  • Real-world (loaded): ~11-12 mpg
  • Real-world (unloaded highway): ~14-17 mpg 



How many miles per gallon does a 2003 Chevy Express 2500 6.0 get?


The van gets about 12 mpg around town and 16-17 on trips going 70 mph. It ha the 6.0 liter V-8.



How many MPG does a Chevy 2500 gas get?


A Chevy 2500's MPG varies, but a gasoline engine typically gets about 14-15 mpg city and 17-19 mpg highway. The Duramax diesel engine is more efficient, getting around 17 mpg city and 23 mpg highway. Actual fuel economy depends on factors like driving style, towing, and vehicle load, with real-world results for the gas engine often around 15.5 mpg combined, while towing can lower mileage significantly.
 
Gas engine

  • City: Approximately 14–15 mpg
  • Highway: Approximately 17–19 mpg
  • Combined: Around 15 mpg 

Duramax diesel engine
  • City: Approximately 17 mpg
  • Highway: Approximately 23 mpg 

Factors affecting MPG
  • Load and towing: Hauling or towing significantly decreases fuel economy. 
  • Driving habits: Aggressive acceleration and high speeds will lower MPG. 
  • Vehicle weight: The weight of the truck and its contents influences fuel consumption. 
  • Aerodynamics: Larger accessories or modifications can affect efficiency. 



How many miles per gallon does a Chevy Express van 2500 get?


The Express Cargo 2500 engines both offer standard work van gas mileage. The V6 engine gives you approximately 14 miles per gallon combined highway and city driving, and the V8 will give you around 13. You can get up to 20 miles per gallon if you choose the diesel.
