How many gallons is a Ford F250 gas tank?

Most Ford F-250s equipped with a gasoline engine use a 34-gallon fuel tank. The exact capacity can vary by year, engine option, and body configuration.


In this article, we explain why tank size varies, which engines typically share the capacity, and how you can verify the precise figure for your specific truck.


What determines the tank size?


Tank capacity is not identical across every F-250; it depends on engine choice and cab/bed setup. Here are the main factors that influence the number you’ll see on papers and stickers.



  • 6.2L V8 gasoline engine: typically 34 gallons

  • 7.3L V8 gasoline engine: typically 34 gallons


In practice, gasoline F-250s in common configurations use a 34-gallon tank, but always confirm with your vehicle’s official documentation for the exact figure.


How to verify the exact capacity for your truck


To confirm the precise fuel tank size for your specific F-250, check these sources in order.



  1. Window sticker (Monroney label) from the dealer or original sale, which lists tank capacity

  2. Owner’s manual or the official Ford spec sheet for your model year

  3. Driver’s door jamb sticker or the vehicle build sheet, which may show fuel capacity


Having the exact capacity on hand helps with fuel planning, especially when towing, carrying payload, or calculating range.


Practical range considerations


With a typical 34‑gallon tank and engine options that deliver roughly 15–20 miles per gallon in mixed driving, most F-250 gasoline models can cover on the order of 500–700 miles per tank, depending on load, terrain and driving style. Always use EPA estimates for your specific configuration when planning long trips.


Summary


The standard gasoline Ford F-250 tank is 34 gallons, though exact capacity can vary by year, engine and configuration. For the most accurate figure, consult the window sticker, owner’s manual, or Ford’s official specifications for your truck. Understanding the tank size helps with planning range and fuel stops, especially when towing or carrying heavy loads.
