How much gas does a Chevy Suburban hold?
The Suburban typically carries about 31 gallons of gasoline, or roughly 117 liters, in its tank.
This capacity is the baseline for many modern Suburban models, but exact numbers can vary by year, drivetrain, and trim. When planning trips or estimating range, it’s helpful to verify the specific figure for your exact vehicle.
Standard capacity for recent Suburbans
For contemporary Suburban configurations, the official specification is commonly listed as 31 gallons. This applies across most two-wheel-drive and four-wheel-drive versions and across the common engine options.
- Common capacity: 31 gallons (about 117 liters) for most current Suburban models.
With a 31-gallon tank, driving range depends on fuel economy and driving conditions. Rough estimates place typical range on the order of 450–700 miles per tank, varying with engine choice, payload, terrain, and speed.
Variations by year and trim
While 31 gallons is standard for most recent generations, some older configurations or special editions can show minor differences. To be certain, check the exact specification for your model year and trim.
- Most recent generations: 31 gallons (117 L) in both 2WD and 4WD versions.
- Older or special configurations: consult the specific brochure or owner's manual for your year to confirm any deviation.
If you’re planning a long trip or comparing vehicles, confirming the precise tank size for your exact Suburban is worthwhile, since even small differences can affect range calculations.
How to verify the capacity for your exact vehicle
Because tank sizes can differ slightly by year and trim, use these steps to confirm the capacity for your Suburban:
- Refer to the owner's manual or the official spec sheet for your model year, which lists the tank capacity.
- Check the fuel-filler door label or the door jamb sticker on your vehicle for a capacity figure.
- Provide your VIN to a Chevrolet dealer or GM customer service to retrieve the exact tank capacity for your build.
Armed with the exact figure, you can more accurately estimate range and plan fuel stops based on your typical driving conditions.
Estimating range per full tank
Using a rough mpg range for a Suburban (which varies by engine and drivetrain), a 31-gallon tank can yield commonly cited ranges from roughly 450 miles (city-heavy driving) to over 700 miles (highway-heavy driving). Real-world results depend on the specific engine, payload, terrain, and driving habits.
Summary
The Chevy Suburban’s fuel tank is generally 31 gallons (about 117 liters) for most modern models, offering substantial driving range. Always verify the exact capacity for your specific year and trim to ensure accurate planning, especially for long trips or when comparing different Suburban configurations.
