22 MPG combined is the fuel economy to expect from a 2017 Subaru Outback with the 3.6-liter six-cylinder engine. It’s not a stellar figure. But to focus solely on this number misses the benefit of this Outback. This isn’t a Prius chasing hypermile records. It’s a reliable, capable, all-wheel-drive wagon designed for adventure, hauling gear, and tackling challenging conditions that would leave most family SUVs spinning their wheels. For the Outback 3.6R buyer, fuel economy is a secondary consideration after performance and year-round usability.
City and highway performance
The EPA estimates suggest 20 MPG in the city and 27 MPG on the highway. The city figure is arguably the more relevant of the two for this particular engine choice. While the Outback’s 2.5-liter four-cylinder provides adequate power for everyday commuting, the 3.6-liter is specifically chosen for its superior passing power and effortless acceleration. That extra power comes at a cost, and stop-and-go city driving will impact your fuel budget.
On the open road, the Outback 3.6R settles into a more efficient cruise, and achieving the 27 MPG highway rating is possible with a light foot. Just don’t expect miracles when overtaking slower traffic; the temptation to tap into that readily available power is often too strong to resist.
Annual fuel cost
The EPA estimates the annual fuel cost for the 2017 Subaru Outback 3.6R at $2,000. This assumes 15,000 miles driven per year, with a mix of city and highway driving that reflects typical use. The calculation also relies on prevailing national average fuel prices. Of course, your actual expenses will vary based on your driving habits and local fuel costs, but $2,000 provides a useful benchmark against which to compare other vehicles.
Consider this figure within the context of your overall vehicle budget and how it compares to the benefits the Outback 3.6R offers.
Real-world expectations
While the EPA’s numbers provide a baseline, real-world fuel economy often differs. Expect to see figures close to the EPA estimates if you drive conservatively and prioritize fuel efficiency. However, if you frequently use the Outback’s full performance capabilities or spend a significant amount of time in heavy traffic, your mileage will likely fall below the official ratings.
Many owners average around 18-23 MPG in mixed driving conditions. Off-road driving, especially in demanding terrain, will further impact fuel consumption. The Outback’s symmetrical all-wheel drive is a valuable asset in tough weather and on rough roads, constantly engages all four wheels, contributing to the lower fuel economy compared to front-wheel-drive competitors.
How it compares
Compared to other wagons and SUVs in its class, the 2017 Outback 3.6R’s fuel economy is mid-pack. A front-wheel drive Toyota Venza from the same year, for example, manages around 22 city and 29 highway. Even the all-wheel-drive Venza still achieves slightly better numbers. A comparable all-wheel-drive Ford Edge with a V6 comes in around 17 city and 25 highway. The difference highlights the compromise: The Outback’s standard all-wheel-drive system gives it superior traction and handling in adverse conditions, but it also adds weight and complexity, impacting fuel efficiency.
If fuel economy is your top priority, consult all Subaru fuel economy data and consider the Outback 2.5i, which offers better MPG at the expense of some horsepower. Or consider models like the smaller Subaru Crosstrek. But for those who need the extra power and capability of the 3.6R, the fuel economy trade-off is often a price worth paying.

Tips to maximize efficiency
Gentle acceleration and braking are critical to squeezing every last mile out of a gallon of fuel. Avoid aggressive driving habits and maintain a steady speed whenever possible. The Outback’s automatic transmission is programmed to shift smoothly and efficiently; allow it to do its job without heavy acceleration.
Regular tire pressure checks are another way to improve fuel economy. Underinflated tires increase rolling resistance, forcing the engine to work harder and consume more fuel. Consult the sticker on your driver’s side doorjamb for the recommended tire pressure, and use a reliable gauge to ensure accurate readings.
Minimize unnecessary weight. The more you carry in your Outback, the more fuel it will consume. Remove any unnecessary items from the cargo area and passenger compartment to reduce the load on the engine. Every extra pound adds up over time.
Proper maintenance is essential for fuel efficiency. Ensure your Outback receives regular oil changes, air filter replacements, and other scheduled maintenance services. A well-maintained engine runs more efficiently, and a clean air filter allows for better airflow and combustion.
Plan your routes carefully to avoid heavy traffic and congested areas. Stop-and-go traffic hurts fuel economy, and time spent idling can impact your overall mileage. Use navigation apps to identify the most efficient routes and avoid potential delays.
