How much gas does a Chevy Trailblazer hold?

The Trailblazer’s fuel tank capacity is roughly 14.3 gallons (about 54 liters).


Across most 2021–2024 models, Chevrolet lists the tank at 14.3 gallons. This capacity supports the subcompact SUV’s balance between usable cargo space and range. The exact figure can vary slightly by drivetrain or model year, but 14.3 gallons remains the standard specification cited by Chevrolet in official materials.


Fuel Tank Capacity Across Model Years


Here is the official capacity reported for the Trailblazer across common configurations.



  • Official capacity: 14.3 gallons (54 liters) for most 2021–2024 Trailblazer models.


What this means for drivers is that you can expect a similar amount of fuel to fill the tank regardless of trim, with variation being minimal and usually within a tenth of a gallon.


Notes on variability


While Chevrolet lists 14.3 gallons as the standard capacity for most models, a small number of regional specs or production runs may show slight differences. Always check the door placard or your owner’s manual for the exact figure for your VIN.


Estimating Range Based on Capacity


To understand how far you can go on a full tank, multiply the fuel economy by the tank size. Here is how to think about it.



  1. Find the EPA-rated combined mpg for your Trailblazer’s engine and drivetrain (for example, front-wheel drive or all-wheel drive).

  2. Multiply that mpg figure by 14.3 gallons to estimate the approximate driving range on a full tank.

  3. Note that real-world range will vary with speed, terrain, cargo, and driving style.


With typical modern small SUVs, the estimate usually lands in the 350–450 mile range for a full tank, depending on engine choice and driving conditions.


Why the Capacity Matters for Daily Use


Fuel tank size affects fueling frequency, road-trip planning, and resale value perceptions. A 14.3-gallon tank gives a practical balance: enough range for daily commutes and weekend trips, without requiring frequent refuels on city streets or highways.


Summary


The Chevy Trailblazer typically holds about 14.3 gallons (54 liters) of gasoline. This standard capacity translates into a practical driving range that varies with engine choice and driving conditions. For planning, use your vehicle’s EPA mpg rating and multiply by 14.3 gallons to approximate how far you can travel on a full tank.

How many miles is $20 of gas?


The number of miles you can drive on $20 of gas depends on the current price per gallon and your vehicle's miles per gallon (MPG). To calculate, divide $20 by the price per gallon to find out how many gallons you can buy, then multiply that number by your car's MPG. For example, with gas at $3.50 per gallon and your car getting 25 MPG, you could drive approximately 142 miles ($20 / $3.50 per gallon ≈ 5.71 gallons; 5.71 gallons * 25 MPG ≈ 142 miles). 
Here is a step-by-step guide:

  • Find the price per gallon: Check local gas prices, as they vary by location. 
  • Calculate the number of gallons: Divide $20 by the price per gallon. For example, if gas is $3.50/gallon, you get about 5.71 gallons ($20 / $3.50 = 5.71). 
  • Determine your car's MPG: This is your vehicle's fuel efficiency, which can be found in your owner's manual or on a sticker inside the car. 
  • Calculate the total miles: Multiply the number of gallons you can buy by your car's MPG. In the example above, 5.715.715.71 gallons ×cross× 252525 MPG ≈is approximately equal to≈ 142142142 miles. 

Factors that affect your actual mileage include driving style, city vs. highway driving, and vehicle maintenance.



How many miles can a Trailblazer go on a full tank of gas?


A Chevrolet Trailblazer can go approximately 350 to 420 miles on a full tank, depending on the model year, engine, and whether it's front-wheel drive (FWD) or all-wheel drive (AWD). For example, a 2025 FWD model can travel around 400-420 miles on the highway, while an AWD version might get closer to 350 miles. 

  • FWD (Front-Wheel Drive): Expect a range of approximately 382 to 420 miles, especially in highway driving conditions. 
  • AWD (All-Wheel Drive): The range is typically lower, around 350 to 409 miles, due to the slight fuel economy difference. 



Are Chevy Trailblazers good on gas?


Yes, Chevy Trailblazers are generally considered good on gas, especially for an SUV, with the most efficient front-wheel-drive (FWD) models getting up to 31 mpg combined. The exact fuel economy varies by engine and drivetrain, with all-wheel-drive (AWD) models being slightly less efficient.
 
2024-2025 Trailblazer MPG by configuration

  • 1.2L Turbo (FWD): 29 mpg city / 31 mpg highway / 30 mpg combined 
  • 1.3L Turbo (FWD): 29 mpg city / 33 mpg highway / 31 mpg combined 
  • 1.3L Turbo (AWD): 26 mpg city / 29 mpg highway / 27 mpg combined 



How many gallons of gas does a Chevy Trailblazer hold?
