How many miles per gallon does a 2015 Chevy Express get?

In brief, the 2015 Chevy Express typically gets about 12–18 miles per gallon overall, with higher efficiency from the 4.3-liter V6 and lower mileage from the larger V8 options. Real-world results vary widely based on payload, driving conditions, and configuration.


What follows is a breakdown of fuel economy for 2015 Express vans, organized by engine and model setup. The Express line offered several powertrains and cargo/passenger configurations that influence mpg figures.


Fuel economy by engine and configuration


The following EPA estimates reflect typical values for 2015 Express models. Actual mileage will vary with load, tire size, driving style, and maintenance.



  • 4.3-liter V6: approximately 15 mpg city / 22 mpg highway; combined around 18–19 mpg.

  • 5.3-liter V8: roughly 14 mpg city / 19–20 mpg highway; combined around 16–18 mpg.

  • 6.0-liter V8: about 11–12 mpg city / 17–18 mpg highway; combined around 14–15 mpg.


Conclusion: For the best overall efficiency, the 4.3L V6 variant tends to offer the strongest mpg, especially on highway driving. The larger 5.3L and 6.0L V8 options trade lower fuel economy for greater towing and payload capabilities. Real-world results will be lower with heavy cargo or frequent stop-and-go driving.


Factors that influence fuel economy


Several elements can swing the Express’s miles-per-gallon beyond the base figures above. Vehicle weight from payload, tire type and inflation, aerodynamic drag, driving style, and maintenance all play major roles in actual fuel economy.



  • Payload and GVWR: Heavier loads reduce efficiency, particularly in city driving.

  • Tire condition and size: Worn or oversized tires increase rolling resistance and lower mpg.

  • Driving behavior: Frequent acceleration, high speeds, and idling hurt fuel economy.

  • Maintenance: Regular service, clean air filters, and proper oil changes help preserve mpg.


Summary: The 2015 Chevy Express offers a range of mpg depending on engine choice and usage. Expect higher highway efficiency from the 4.3L V6 and progressively lower mpg with the 5.3L and especially the 6.0L V8, with real-world results significantly affected by payload and driving conditions.


Summary


Engine choice drives the main mpg difference: 4.3L V6 around 18–19 mpg combined, 5.3L V8 around 16–18 mpg combined, and 6.0L V8 roughly 14–15 mpg combined. Real-world mileage will vary, but payload, road conditions, and maintenance have large impacts on final fuel economy.
