How many gallons of gas can a Ram 1500 hold?

The Ram 1500 typically comes with a 23-gallon fuel tank, but certain configurations offer a larger 33-gallon tank for extended range. Exact capacity varies by model year, cab and bed size, and whether an optional larger tank is installed.


Understanding how tank size varies by configuration


Fuel-tank capacity on the Ram 1500 is not a single fixed number. It changes with factors such as the cab style (Regular, Quad, or Crew), bed length, engine choice, and the presence of an optional larger tank package. For buyers and owners, knowing the exact figure for a given build requires checking the vehicle’s door jamb sticker or the official window sticker from the dealership, or consulting the owner’s manual for that specific model year and configuration.


Common capacities you might encounter


Before listing the capacities, note that the range below reflects configurations commonly documented by manufacturers for the Ram 1500. Actual figures can vary by year and trim.



  • Standard tank size: 23 gallons (typical on many base and mid-range gasoline configurations).

  • Optional larger tank: 33 gallons (available on select long-bed and crew-cab configurations to extend driving range).


For the most precise figure for a specific Ram 1500 (by year, trim, and cab/bed configuration), refer to the owner’s manual or the original window sticker, or contact a Ram dealer directly.


Why the capacity matters and how to confirm it


Fuel-tank size influences how far you can drive between fills, fuel economy expectations, and planning for long trips. If you’re considering a used Ram 1500 or evaluating a new purchase, verify the exact tank capacity on the specific build you’re interested in, since options can differ even within the same model year.


Summary


In short, the Ram 1500 commonly features a 23-gallon fuel tank, with a larger 33-gallon option available on certain configurations. Always confirm the exact capacity for your particular truck by checking the door sticker, window sticker, or owner’s manual, as capacity can vary by year, cab/bed combination, and optional equipment.
