How big is the gas tank on a 2025 Chevy Trailblazer?

The gas tank on the 2025 Chevy Trailblazer is about 12.2 gallons (46 liters).


Chevrolet lists this capacity as the baseline for most trims, with only minor variation by drivetrain and packaging. Here's what that means for range and how to verify the exact figure for your specific vehicle.


Tank size at a glance


The 12.2-gallon figure is the standard specification cited by Chevrolet for the 2025 Trailblazer. In practice, most owners will see the same capacity, while a small variation may occur depending on whether the model is front-wheel drive or all-wheel drive, as well as any regional packaging differences.



  • Standard capacity: 12.2 gallons (46 liters) in the majority of trims.

  • Drivetrain variation: Any differences between FWD and AWD are typically minor and not a full gallon apart.


The takeaway is that you should expect roughly a 12.2-gallon tank, which translates to a practical driving range that depends on your EPA fuel economy and driving style.


How to verify the exact capacity for your Trailblazer


To confirm the precise tank size for your specific 2025 Trailblazer, use these steps:



  1. Check the fuel-filler door label on your vehicle; the capacity is listed there along with other specs.

  2. Consult the owner's manual's specifications page for the fuel-tank capacity.

  3. View Chevrolet's official 2025 Trailblazer brochure or product page for your trim level; the PDF or spec sheet usually lists the tank size.

  4. Ask a Chevrolet dealer or use a VIN-based build sheet to confirm any model-year or regional variations.


With these steps, you can determine the exact capacity for your build and understand any minor discrepancies you might observe in marketing materials versus your own vehicle.


Summary


The 2025 Chevy Trailblazer uses a 12.2-gallon fuel tank as the standard specification. While the capacity can vary slightly due to drivetrain and regional packaging, 12.2 gallons is the baseline.
