How many gallons is a 1500 Silverado tank?

The Silverado 1500 commonly uses a 24-gallon fuel tank. Exact capacity can vary by engine, cab/bed configuration, and model year.


Chevrolet’s official specifications traditionally list 24 gallons (about 90.8 liters) as the standard tank size for the 1500 lineup. Because configurations differ, it’s best to verify the exact number for your specific truck using the door jamb sticker or the owner’s manual.


Overview of tank size across typical configurations


Before looking at specifics, note that most 1500 models share the same general fuel-tank footprint, but there are nuances depending on the drivetrain and body style.



  • Gasoline engines (including 2.7L turbo, 5.3L V8, and 6.2L V8) with crew or extended cabs and various bed lengths: 24 gallons.

  • Duramax 3.0L diesel: 24 gallons.


In practice, the vast majority of Silverado 1500 configurations use a 24‑gallon tank. Always confirm the exact figure for your specific build through official documentation or the vehicle’s labeling.


How to confirm your exact capacity


To determine the precise tank size for your Silverado 1500, check the doorjamb sticker on the driver’s door, consult the owner’s manual, or review the vehicle’s build sheet (MSRP/Option Package reference). These sources list the exact fuel-tank capacity for your model and configuration.


What to consider beyond the number


Tank size is just one factor in overall range. Real-world range depends on engine choice, transmission, drivetrain, payload, and driving conditions. If you’re weighing fuel economy versus capacity, the 24-gallon standard generally balances well with typical highway and city driving for this truck line.


Summary


For most Chevrolet Silverado 1500 models, the fuel tank size is 24 gallons. While this covers the majority of configurations, the exact capacity can vary by engine, cab/bed setup, and model year. Always verify with your vehicle’s documentation or labeling for precise figures.
