How many gallons of fuel does a Suburban take?

A Chevrolet Suburban typically has a fuel tank capacity of 24 to 31 gallons, depending on the model year and configuration. The exact fuel tank size can vary, but most Suburban models have a sizable gas tank to accommodate their large size and power needs.


Fuel Tank Capacity of the Chevrolet Suburban


The Chevrolet Suburban is a full-size SUV known for its spacious interior, powerful engine options, and impressive towing capacity. Given its large size and weight, the Suburban requires a substantial fuel tank to provide adequate range and performance.



  • Most Suburban models have a fuel tank capacity ranging from 24 to 31 gallons.

  • The exact fuel tank size can vary depending on the model year, engine, and drivetrain configuration.

  • Older Suburban models (pre-2015) typically had a 26-gallon fuel tank, while newer models may have a 28- or 31-gallon tank.

  • The Suburban's fuel tank size is larger than many other full-size SUVs, which often have 20-25 gallon tanks.


The larger fuel tank capacity allows the Suburban to have a longer driving range between fill-ups, which is important for a vehicle of its size and weight. This is especially beneficial for those who use the Suburban for towing, hauling, or long-distance travel, as the extra fuel capacity can help reduce the number of stops required.


Factors Affecting Fuel Consumption


While the Suburban's fuel tank capacity is substantial, its actual fuel consumption can vary depending on several factors:



  • Driving Conditions: Fuel economy is typically lower when towing heavy loads, driving in stop-and-go traffic, or operating in extreme temperatures.

  • Engine and Drivetrain: Suburban models with larger engines, four-wheel drive, or heavy-duty towing packages may have lower fuel efficiency.

  • Driving Habits: Aggressive acceleration, high-speed driving, and frequent idling can all contribute to increased fuel consumption.


Owners of the Chevrolet Suburban should be mindful of these factors and adjust their driving habits accordingly to maximize their vehicle's fuel efficiency and range.
