22 MPG combined isn’t going to win any fuel economy awards, but for the 2019 Subaru Outback AWD 3.6L 6-cyl, it represents a calculated compromise. This isn’t a vehicle purchased for its frugality; it’s for those who prioritize reliable, go-anywhere capability and the smooth power delivery of a naturally aspirated six-cylinder engine.

City and highway performance

The EPA estimates paint a straightforward picture: 20 MPG in the city and 27 MPG on the highway. The city figure reflects the reality of hauling around an all-wheel-drive vehicle in stop-and-go traffic, where the engine works harder and the automatic transmission cycles frequently. The highway number, however, is respectable, showcasing the benefit of the Outback’s aerodynamics and relatively relaxed cruising RPMs. While some might find 27 MPG highway adequate, remember this isn’t a hybrid or even a turbocharged four-cylinder designed with maximizing fuel efficiency as its primary goal.

Annual fuel cost

The EPA estimates the annual fuel cost for the 2019 Subaru Outback AWD 3.6L at exactly $2,000. This figure is based on driving 15,000 miles per year and using the national average fuel prices at the time of calculation. Naturally, your individual fuel costs will vary depending on your driving habits, the type of roads you frequent, and fluctuations in gasoline prices. However, it provides a standardized benchmark for comparing the Outback’s running costs to those of other vehicles.

Real-world expectations

While EPA numbers provide a baseline, real-world fuel economy often differs. Owners of the 2019 Outback 3.6L frequently report numbers close to the EPA estimates, but aggressive driving, frequent short trips, or consistently carrying heavy loads can lower the average. Conversely, those who prioritize smooth acceleration, maintain consistent highway speeds, and diligently adhere to recommended maintenance schedules may see slightly better fuel economy. Potential buyers should understand that all Subaru fuel economy data includes a trade-off for its legendary off-road capability.

How it compares

Compared to other vehicles in its class, the 2019 Outback 3.6L’s fuel economy lands somewhere in the middle. A comparable Toyota RAV4 AWD, typically equipped with a four-cylinder engine, achieves around 28 MPG combined. The Honda CR-V AWD manages a similar figure. However, these vehicles lack the smooth power and towing capacity offered by the Outback’s six-cylinder engine. Stepping up to larger SUVs like the Jeep Grand Cherokee with a V6 will likely result in even lower fuel economy, often hovering around 21 MPG combined. Buyers choosing the 3.6L are explicitly prioritizing power and refinement over outright fuel savings, a trade-off carefully considered for the OUTBACK MPG across all years.

Tips to maximize efficiency

Though outright fuel efficiency might not be the primary concern for Outback 3.6L owners, there are still several strategies to minimize fuel consumption. Ensuring your tires are properly inflated to the pressure listed on the door jamb reduces rolling resistance and improves gas mileage. Check tire pressure regularly, especially with seasonal temperature changes.

Gentle acceleration and consistent speeds are key to maximizing fuel economy in any vehicle, but especially in one with a larger engine. Avoid aggressive starts and hard braking, anticipate traffic flow, and maintain a steady pace on the highway. The Subaru’s automatic transmission will operate more efficiently if it’s not constantly shifting due to erratic throttle inputs.

Regular maintenance, including oil changes and air filter replacements, can significantly impact fuel economy. A clean air filter ensures optimal airflow to the engine, while fresh oil reduces friction and improves overall efficiency. Adhering to the manufacturer’s recommended maintenance schedule is critical for long-term performance and fuel economy.

Minimize unnecessary weight in the vehicle. Carrying extra cargo reduces fuel economy, as the engine has to work harder to accelerate and maintain speed. Remove any items from the cargo area or roof rack that you don’t need for your current trip, as excess weight, even in small amounts, adds up over time.

Consider using cruise control on long highway drives. Cruise control helps maintain a consistent speed, which can improve fuel economy. However, avoid using cruise control in hilly terrain, as the transmission may downshift frequently, negating some of the fuel savings. Judicious use of cruise control in relatively flat regions will offer the greatest benefit.
