How big is the gas tank on a 2025 Subaru Forester?
The 2025 Subaru Forester uses a 16.9-gallon (64-liter) fuel tank, a capacity that remains consistent with recent model years.
Official fuel capacity
Here is the core specification that affects how far you can travel between fill-ups and how often you’ll need to stop for gas.
- 16.9 gallons (64 liters) total capacity.
The 16.9-gallon tank provides a practical balance between cargo space, weight, and range, and Subaru stores this capacity across all 2025 Forester trims.
Estimated range and fuel economy
Fuel economy and driving habits influence how far the Forester can go on a full tank. For the 2025 model with the standard 2.5-liter engine and all-wheel drive, EPA estimates and typical real-world use place range in the mid-to-upper 400s miles per tank on average, with highway driving delivering higher miles per gallon than city driving.
- Typical combined range on a full tank is about 480–510 miles (roughly 770–820 kilometers) when the vehicle achieves around 29–30 mpg combined.
- On steady highway runs that approach ~33 mpg highway, the range can extend toward about 550–560 miles per tank, depending on conditions.
Note: These figures are approximate and depend on exact trim, tire size, driving style, weather, and terrain. For precise, up-to-date numbers, consult Subaru’s official specifications and EPA ratings for the specific build.
Trim-wide consistency
In practice, the gas tank size is advertised as the same across Forester trims for the 2025 model year. This uniformity helps buyers estimate their range regardless of whether they choose base or higher trims.
Summary
The 2025 Subaru Forester is equipped with a 16.9-gallon (64-liter) fuel tank, offering an estimated driving range roughly in the 480–560 mile band depending on driving conditions and efficiency. This consistency across trims makes planning refueling stops straightforward for most buyers.
