How big is the fuel tank on a 2007 Subaru Legacy?

The 2007 Subaru Legacy uses a 16.9-gallon (64-liter) fuel tank, a capacity that applies across the main trims. In practice, that means a full tank can take you several hundred miles depending on engine and driving conditions.



Fuel Tank Capacity Across the 2007 Legacy lineup


Before listing the typical capacity by trim, note that the tank size is the same across the main trims, providing consistency for planning and resale.



  • 2.5i (including 2.5i Limited): 16.9 gallons (64 liters)

  • 3.0R Limited: 16.9 gallons (64 liters)


Across these trims, Subaru used the same fuel tank capacity, so the practical effect on range is determined primarily by engine efficiency rather than tank size.


Practical implications for range and driving


With a 16.9-gallon tank, drivers estimate range by multiplying the tank volume by the vehicle's fuel economy. The four-cylinder models typically achieve mid-20s miles per gallon combined, yielding a practical driving range in the hundreds of miles per full tank, while the 3.0L H6 consumes more fuel, reducing range. Real-world mileage varies with driving style, terrain, and cargo load.


Tips for planning


Consider your typical routes and fuel availability on longer trips, and aim to refuel before the gauge nears the empty mark to avoid getting stuck in sparse areas.


Summary


The 2007 Subaru Legacy uses a uniform 16.9-gallon (64-liter) fuel tank across its main trims, simplifying planning and fuel budgeting. Range will depend on engine choice and driving conditions, but the tank size provides a reliable basis for estimating how far you can go on a fill.
