What size gas tank does a 1500 truck have?
Gas tank capacity for a 1500-class pickup varies widely by make, model year, engine, cab and bed configuration. There is no single size that applies to every 1500; this piece outlines typical ranges and how to determine the exact figure for your truck.
Typical tank sizes across popular 1500 pickups
Manufacturers offer several tank sizes within the 1500 lineup, tailored to balance range, payload, and towing. The figures below reflect common configurations in recent years; exact capacity depends on engine choice, cab/bed configuration, and any optional fuel tank packages.
- Ford F-150: Roughly 23 gallons in standard configurations, with some trims offering larger extended-range tanks in the mid- to upper-20s gallons and up to around 34 gallons in certain setups.
- Ram 1500: Typically about 23 to 32 gallons, with 26- and 32-gallon tanks being common depending on the configuration.
- Chevrolet Silverado 1500: Generally in the 24 to 34 gallon range, depending on cab, bed, and trim.
- GMC Sierra 1500: Similar to the Silverado, commonly 24 to 34 gallons depending on configuration.
Because fuel-tank options differ by model, trim, and production year, the exact capacity for a given truck should be checked in the official specs or owner's manual.
Factors that influence a 1500’s fuel-tank size
Several design choices determine how large a pickup’s gas tank is, affecting range and weight distribution.
- Engine and performance targets, including towing capacity
- Cab and bed configuration (e.g., Crew Cab with longer bed may drive a larger tank)
- Availability of extended-range or auxiliary fuel tanks
- Market-specific or trim-specific options and packages
Understanding these factors helps explain why two 1500 pickups from the same brand can have different driving ranges.
How to find the exact tank size for your vehicle
To know the precise fuel capacity of a specific 1500 pickup, check the vehicle’s official specifications for the exact year, make, model, trim, engine and bed configuration. This information is usually listed in the owner's manual, the manufacturer’s site, or the window sticker. If you share your exact model-year and trim, I can help pinpoint the precise tank size.
Summary
Gas-tank capacity for 1500 pickups varies widely, typically ranging from the low 20s to the mid-30s gallons depending on configuration. Always verify for your exact truck to know your expected driving range.
