How much gas does a 2016 Subaru Outback hold?

The 2016 Subaru Outback is equipped with an 18.5-gallon fuel tank (about 70 liters).


Capacity and engine options


The fuel tank capacity remains 18.5 gallons across the 2016 Outback’s US market engine choices, including the 2.5-liter four-cylinder and the optional 3.6-liter six-cylinder.


Two engine choices in 2016


In 2016, the Outback offered a 2.5L i4 as the standard engine and an optional 3.6L H6. Both configurations use the same 18.5-gallon tank, meaning the cargo for fuel capacity is consistent regardless of engine choice.


Estimated driving range on a full tank


Using EPA fuel economy figures for the 2016 model year, the following estimates reflect typical ranges on a full 18.5-gallon tank. These are approximate and depend on driving conditions and vehicle maintenance.



  • 2.5-liter engine: City about 463 miles; Highway about 611 miles; Combined about 518 miles.

  • 3.6-liter engine: City about 370 miles; Highway about 500 miles; Combined about 426 miles.


In practice, your actual range will vary with terrain, load, driving style, climate control usage, and other factors.


Practical considerations


Fuel capacity affects how far you can travel between fills, but real-world range often differs from EPA estimates. If you routinely drive long highway trips, the 2.5L model will typically achieve a higher highway range per tank than the 3.6L variant due to better efficiency, while city driving will favor the smaller engine for its efficiency advantage.


Summary


The 2016 Subaru Outback holds 18.5 gallons (about 70 liters) of gas, a capacity shared by its two main US engines. Estimated ranges on a full tank vary from roughly 370–611 miles depending on engine and driving conditions, with typical combined-range figures around the mid-400s to high-500s miles. Always consider real-world factors when planning fuel stops.

Can I put 87 gas in my Subaru Outback?


Regular fuel: Models such as the Forester, Outback, and Crosstrek run efficiently on regular unleaded or 87-octane fuel. Using higher-octane fuel in these vehicles won't harm the engine, but it doesn't offer any benefit in terms of performance.

Safety and mechanical
  • Brake pedal: A recall was issued for concerns with the brake pedal. 
  • Steering column: A steering column recall was issued for vehicles manufactured between February 29, 2016, and May 6, 2016, due to improperly machined parts that could cause steering issues. 
  • Airbag: Some models had a recall related to the airbag inflator. 
  • Muffler baffles: Baffles inside the muffler may come loose. 
  • Windshield: Some owners report weak windshields prone to cracking. 

Key takeaways
  • Check for recalls: Verify that any vehicle you are considering has had all applicable recalls addressed, especially those related to the steering column and airbags. 
  • Consider battery life: Be aware of the potential for the 12V battery to drain quickly and budget for a possible replacement or upgrade. 
  • Inspect electronics: Look for signs of issues with the infotainment system and blower motor. 
  • Plan for maintenance: Regular fluid changes are crucial for the CVT transmission, and routine inspections can help identify potential oil leaks early.
