How big is a Dodge Ram 1500 gas tank?
The Ram 1500’s gasoline tank size is not the same for every truck. Most models use a 26-gallon tank (about 98.4 liters), but select regular-cab/short-bed configurations can have a 23-gallon tank. The exact capacity depends on engine, cab style, bed length, and model year.
Tank sizes by configuration
The following describes the most common tank sizes you’ll encounter on today’s Ram 1500 lineup. Sizes vary by engine and body style, so always verify the exact capacity for your specific vehicle using the window sticker or official Ram specifications for your VIN.
- 26 gallons (98.4 liters): The majority of Ram 1500 models, including crew-cab and quad-cab configurations with gas engines (such as the 5.7L Hemi or the 3.6L Pentastar) and versions equipped with the EcoDiesel, use a 26-gallon tank.
- 23 gallons (87.1 liters): Some regular-cab, short-bed configurations may use a 23-gallon tank. Always check the exact spec for your truck.
In practice, the 26-gallon tank is by far the most common configuration in recent model years, providing a longer driving range between fills. The 23-gallon variant appears primarily in select regular-cab/short-bed builds where a smaller tank was chosen for packaging or cost considerations.
How to confirm the exact capacity
To be certain of your Ram 1500’s tank size, consult the owner’s manual, review the Monroney (window) sticker on a new vehicle, or check the official Ram specifications for your model year and VIN. A dealership can pull the precise spec for a given VIN.
Practical implications for range
Fuel range depends on engine choice and driving conditions. Generally, a 26-gallon tank offers a longer range than a 23-gallon tank. For example, with a hypothetical 18 miles per gallon combined rating, a 26-gallon tank could provide about 468 miles of range, while a 23-gallon tank might offer around 414 miles. Actual figures vary with equipment, drivetrain, and driving style.
Summary
Overall, the Ram 1500’s tank size is most commonly 26 gallons, with 23 gallons used in some regular-cab/short-bed configurations. Always verify the exact capacity for your vehicle via the window sticker or VIN-specific Ram specifications to avoid assumptions.
