How many gallons of gas does a 2024 Subaru Outback hold?
The 2024 Subaru Outback holds 18.5 gallons of fuel in its tank (about 70 liters).
This capacity is standard across the 2024 lineup, including both the base 2.5-liter engine and the available 2.4-liter turbo, and it generally does not vary by trim in most markets. Real-world range depends on the chosen engine, drivetrain, and driving conditions.
Fuel capacity and practical implications
The 18.5-gallon tank provides a substantial cruising distance between fills. Because the two available engines have different fuel economies, the actual range will vary with configuration and driving style. For precise numbers, refer to the EPA ratings for your specific engine and drivetrain on Subaru’s official site or the EPA fuel economy database.
Engines and how they relate to efficiency
Outback configurations include a 2.5-liter four-cylinder engine and a 2.4-liter turbocharged option. Both share the same 18.5-gallon fuel tank, so capacity is not a deciding factor between these powertrains; instead, fuel economy—and thus potential range—differs between them.
Additional context
Fuel tank capacity is a key element for planning trips, fueling stops, and overall ownership costs. Subaru’s official specification pages confirm the 18.5-gallon figure, which translates into a practical range that depends on EPA fuel economy estimates and real-world conditions.
Summary: The 2024 Subaru Outback uses an 18.5-gallon fuel tank, consistent across trims and engines. Your actual range will depend on engine choice, drivetrain, and driving conditions. For precise planning, consult the EPA figures for your specific configuration.
