How many gallons of gas can a Subaru Legacy hold?
Most Subaru Legacy models sold in the United States in recent years have a fuel tank capacity of about 16.9 gallons (64 liters). The exact figure can vary slightly by year and trim, with some older generations listed around 16.6–16.9 gallons.
This article explains the typical tank size, how it varies across generations, and how to confirm the precise capacity for your vehicle. It also explains what the size means for driving range and refueling behavior.
Tank capacity by generation and market
Capacity is similar across generations but can differ by model year and market. The following values reflect commonly reported figures for U.S.-market Legacy sedans.
- Most recent generations (roughly 2015–present): about 16.9 gallons (64 liters).
- Earlier generations (late 2000s to early 2010s): commonly around 16.6 to 16.9 gallons, depending on trim and region.
Note: Always check your owner's manual or the Tire and Loading Information label on the door jamb for the exact usable capacity of your specific vehicle.
Impact on driving range and fueling
Tank size directly affects how far you can go between fills, especially when paired with the car's official fuel economy ratings.
- Estimated range varies with MPG; multiply the tank capacity by the combined or highway MPG rating to estimate miles per tank.
- Reserve fuel and fuel gauge accuracy can differ; the official capacity represents usable fuel up to the full mark on the gauge, not always the absolute physical tank volume.
Practical implication: understanding capacity helps with planning trips and budgeting fuel stops, but actual range depends on driving conditions, speed, and maintenance.
How to verify the exact capacity for your Legacy
Because exact capacity can vary by model year and market, verify using these reliable sources.
- Check the door jamb label on the driver's side, which lists the fuel tank capacity and other important specifications.
- Consult the owner's manual for the specific figure for your vehicle's year and trim.
- Visit Subaru's official site or contact a dealer with your VIN to pull the exact specification.
- Look up the vehicle's spec sheet on trusted automotive databases or brochures for your country.
Knowing the precise capacity ensures you have the correct figure for maintenance planning and trip calculations.
Summary
Across modern Subaru Legacy models, the fuel tank capacity typically sits around 16.9 gallons (64 liters), with minor year-to-year variations. Always verify the exact figure for your vehicle using the door jamb label or official documentation.
