How big is the gas tank on a 2012 Chevy Express?
The 2012 Chevy Express cargo van uses a 31-gallon fuel tank (about 117 liters).
This capacity is standard across the Express lineup, including the 1500, 2500, and 3500 chassis. Engine options for that year — such as the 4.3-liter V6 and the 5.3- and 6.0-liter V8s — do not change the overall tank size.
How the capacity applies to different configurations
All regular cargo variants share the same 31-gallon tank, regardless of wheelbase or roof height. Some specialty or passenger configurations can have different fuel-system arrangements, but for typical cargo models the capacity is 31 gallons.
Practical considerations
With a 31-gallon tank, the driving range depends on load, terrain, and driving style. Real-world range will be lower in city driving and higher on highway trips, but the tank capacity itself remains constant across the 2012 Express cargo lineup.
Summary
The 2012 Chevy Express ships with a 31-gallon (approximately 117-liter) fuel tank, a standard specification shared across its cargo-van configurations.
