How big is a Dodge Magnum gas tank?
The Dodge Magnum typically carries about 20.5 gallons (roughly 77.6 liters) of fuel in most configurations, with the Hemi-powered versions edging up toward about 23 gallons (around 87 liters). The exact size can vary by engine and model year.
Typical capacity across the range
Below are the most commonly cited tank sizes for Dodge Magnum configurations. These figures reflect engine types found in the late-2000s Magnum lineup and align with the LX platform family, though exact capacity can differ by production revision.
Engines
- 2.7-liter V6: ~20.5 gallons (77.6 L)
- 3.5-liter V6: ~20.5 gallons (77.6 L)
- 5.7-liter Hemi V8: ~23.0 gallons (87.0 L)
In practice, most non-Hemi Magnum models hover around 20.5 gallons, while the V8 Hemi variants tend toward a larger tank closer to 23 gallons, depending on specific production revisions.
How capacity varies by year and trim
Vehicle tank size is not updated every year, but there can be small differences due to packaging, emissions equipment, or manufacturing tolerances. The information below summarizes typical expectations for the 2005–2008 Magnum range and notes where deviations might occur.
Model-year considerations
- 2005–2008 Magnum models generally show a standard capacity around 20.5 gallons for the base and mid-range trims.
- Hemi-equipped variants tend to use a slightly larger tank, commonly cited near 23 gallons, though exact figures can vary by build date and regional specs.
If you need the precise tank size for a specific vehicle, check the owner’s manual, the original window sticker, or VIN-based factory data, as these sources reflect the exact configuration for that car.
How to verify your exact capacity
To confirm the exact fuel-tank size for your Dodge Magnum, use a few reliable verification methods. These steps help you get an accurate figure for your specific car, rather than relying on general ranges.
- Consult the owner’s manual or the vehicle’s service manual for the official specification.
- Check the Monroney (window) sticker or any original documentation that might list fuel capacity.
- Look for a VIN-based build sheet or factory data sheet from a Chrysler/Jeep dealer or archive; you can request this from the manufacturer using your VIN.
- If official documents aren’t available, you can perform a practical check by filling the tank from empty to full and noting the volume (in gallons) displayed by the pump, keeping in mind safety and accuracy of the pump measurement.
Bottom line: A combination of official documentation and, if needed, a careful fill-to-full measurement will give you the exact capacity for your particular Dodge Magnum.
Summary
The Dodge Magnum’s fuel tank is typically around 20.5 gallons, with Hemi models often nearer to 23 gallons. Exact capacity depends on engine and production specifics, so consult the manual or VIN-based data for your exact figure. For most owners, planning on roughly 21 to 23 gallons depending on configuration provides a practical guide for range calculations and fuel budgeting.
