How far can a Subaru Outback go on a full tank?
Most Subaru Outback models can travel roughly 500 to 600 miles on a full tank, depending on engine choice and driving conditions. This article breaks down the numbers and factors to help you estimate range for your vehicle.
Tank capacity and range by engine
Below is a quick breakdown of range estimates based on the two main engines in the current Outback lineup. These figures assume a full 18.5-gallon tank and typical mixed driving.
Two common engine configurations
- 2.5-liter engine (non-turbo) with all-wheel drive: approximately 26–29 mpg combined, equating to about 480–540 miles on a full tank in mixed driving. Highway efficiency can push toward the higher end of this range.
- 2.4-liter turbo engine: approximately 24–26 mpg combined, equating to about 440–480 miles on a full tank in mixed driving. On sustained highway cruising with favorable conditions, you might see higher efficiency, near 28–30 mpg, expanding range toward 520–555 miles.
Note: Actual range varies with speed, terrain, payload, weather, and tire condition. EPA estimates can also differ by model year and drivetrain.
Tips to maximize fuel range
Even with official numbers, real-world range depends on how you drive and maintain the vehicle. The following tips help you squeeze more miles out of a tank.
- Drive at steady, moderate speeds. Rapid acceleration and heavy braking waste fuel.
- Use cruise control on highways when appropriate to maintain a constant speed.
- Keep tires properly inflated to the recommended pressure.
- Reduce aero drag by removing roof racks or cargo carriers when not in use.
- Avoid excessive weight and roof cargo to minimize rolling resistance.
These practices can noticeably improve mileage, though individual results will vary with conditions and the specific engine configuration.
Summary
On the current Subaru Outback lineup, you can expect roughly 480–540 miles per tank with the 2.5L engine and about 440–480 miles with the 2.4L turbo in typical mixed driving. Tank capacity is 18.5 gallons for recent models. For highway trips or favorable conditions, ranges can stretch toward the upper ends of these estimates. Real-world range will vary with weather, terrain, and driving style.
