Does the Subaru Outback get good gas mileage?
Yes. For a midsize, all‑wheel‑drive wagon, the Outback delivers competitive fuel economy. In typical configurations, the base 2.5-liter engine aims for around 29 mpg combined, while the stronger 2.4-liter turbo aims lower—roughly in the mid‑20s combined—reflecting the trade‑off between efficiency and power.
Engine options and official fuel economy
Overview
The Outback has two main U.S. powertrains that affect mpg: a 2.5-liter flat-four (base) and a 2.4-liter turbocharged flat-four (available on higher trims). Both engines are paired with a CVT and come standard with all-wheel drive in the United States. EPA estimates can vary slightly by model year and wheel/tire setup.
Before examining the official numbers, note that the following summary reflects typical EPA estimates for current U.S. models.
- 2.5-liter base engine (AWD, CVT): approximately 26 mpg city / 33 mpg highway / 29 mpg combined.
- 2.4-liter turbo engine (AWD, CVT): approximately 23 mpg city / 30 mpg highway / 26–27 mpg combined.
Bottom line: the base engine is generally the most fuel-efficient option, while the turbo delivers stronger acceleration with a modest mpg penalty.
Real‑world performance and how to maximize fuel economy
Actual mileage can differ from EPA estimates depending on driving conditions, cargo, tire size, and terrain. Highway cruising at moderate speeds and light loads will typically yield closer to the higher end of the mpg range, while aggressive driving or frequent elevation changes can lower it.
To help maximize efficiency, consider these practical strategies:
- Keep tires inflated to the recommended pressure and ensure proper wheel alignment; underinflated tires reduce efficiency and handling.
- Maintain the engine with scheduled service, including timely oil changes and air filter replacements; a clean intake and proper lubrication improve efficiency.
- Avoid excess weight and roof-mounted cargo when not needed; roof racks and heavy loads increase aerodynamic drag and reduce mpg, especially at highway speeds.
- Practice smooth driving: gradual throttle application, steady speeds, and using cruise control on highways can improve fuel economy.
- Plan trips to minimize stop-and-go driving and take advantage of highway segments when possible.
Concluding paragraph: With mindful driving and routine maintenance, Outback owners typically see mpg in the high 20s in mixed use, and higher-on long highway trips, aligning with expectations for a capable all-wheel-drive wagon in its class.
Summary
The Subaru Outback offers solid fuel economy for its segment, particularly with the base 2.5-liter engine. If you prioritize efficiency over performance, the base engine is the better choice; if you want stronger towing or acceleration, the 2.4-liter turbo is an option with a modest hit to mpg. Real-world results vary, but careful driving and maintenance can help you stay near the EPA estimates.
Why is my Subaru Outback getting bad gas mileage?
It's likely just due to being in the break-in period and you might have been doing more city driving than you realized. I recently reset the trip computer on our outback after a fill-up and was doing mostly city/suburban driving getting about 17 mpg. Just complete the break-in period and it will likely get better.
Is the Subaru Outback fuel-efficient?
With an EPA-estimated gas mileage of up to 32 miles per gallon, the Subaru Outback ensures seamless travels around Flushing.
What is a common problem with a Subaru Outback?
Common problems for the Subaru Outback include weak windshields, excessive oil consumption, and issues with the cooling system and CVT transmission, especially in specific model years. Other frequent complaints involve airbag defects, electrical problems like battery drain, and vibration during acceleration.

Engine and powertrain
- Excessive oil consumption: Many models, particularly older 2.5L engines, may burn oil between oil changes due to leaks from seals.
- Cooling system failures: Overheating can lead to blown head gaskets, and the cooling system itself is a common point of failure.
- CVT transmission problems: Some model years are more susceptible to issues like rough shifting or failure.
- Vibration during acceleration: Some owners report a shudder or vibration when accelerating.
- Older head gasket issues: The EJ-series engines (roughly 1997–2012) had an inherent head gasket failure problem, though this was mostly resolved in later models.
Body and electrical
- Weak windshields: The glass is prone to cracking from stress or minor impacts.
- Airbag defects: Some models have a history of airbag problems, leading to recalls.
- Electrical issues: Problems can include unexpected battery drain and issues with the ABS control module.
Other common issues
- Oxygen sensor failure: The front O2 sensor can fail, sometimes leading to a recall.
- Premature brake wear: Some models experience faster-than-average brake wear.
- Suspension wear and tear: Like many vehicles, suspension components will eventually wear out.
Are Subaru Outbacks good for long distance driving?
No matter what your travel plans look like, maybe you're heading to the mountains, visiting friends and family across the state, or taking your kids to the beach, the Subaru Outback can be considered the perfect road trip vehicle. Why? Because it is built to handle just about any challenge you throw at it.
