Subaru Outback Oil Capacity & Oil Type
TL;DR
Capacity depends heavily on engine code and generation, not just the model name - always confirm your exact engine before topping off.
Subaru Outback engine oil capacity by engine code
The Outback has used several distinct engine families over the years, and each one takes a different amount of oil. Going by model year alone can mislead you, since Subaru switched engine codes more than once while keeping the same body style on sale. Always match the figures below to the engine code stamped on your car, not just the model year.
Naturally aspirated 2.5L engines (EJ25 and FB25)
The older EJ25 (used through 2009) and the newer FB25 (2010-present) share a displacement but are different engines with different capacities. The FB25 also changed slightly across its own production run, so a 2012 and a 2023 Outback with the same badge do not necessarily take the same amount of oil.
Turbocharged and six-cylinder engines
The 2.4L turbo FA24 (2020-present) and the older 3.6L six-cylinder EZ36 (3.6R trim) both take more oil than the four-cylinder naturally aspirated engines, reflecting their larger displacement and different filter housings.
| Engine code / years | Capacity with filter (L / US qt) | Viscosity |
|---|---|---|
| EJ25, naturally aspirated (approx. 2000-2009) | 4.0-4.2 L / 4.2-4.4 US qt | 5W-30 |
| FB25, naturally aspirated (2010-2014) | 4.2-5.2 L / 4.4-5.5 US qt (sources vary by sub-year) | 0W-20 |
| FB25, naturally aspirated (2015-2019) | 4.8 L / 5.1 US qt | 0W-20 |
| FB25, naturally aspirated (2020-present) | 4.2 L / 4.4 US qt | 0W-20 |
| FA24, turbocharged 2.4L (2020-present) | 4.5 L / 4.8 US qt | 0W-20 |
| EZ36, 3.6L 6-cylinder, 3.6R trim (approx. 2010-2014) | 6.5 L / 6.9 US qt | 5W-30 |
Where to confirm your exact figure
Because capacity varies within the same engine family, the safest confirmation is always your own vehicle. Check the oil filler cap or the underhood emissions/specifications sticker, and cross-reference with your owner's manual (glovebox document or Subaru STARLINK digital manual). A dealership service advisor can also pull the exact figure from Subaru's service data using your VIN.
Why the FB25 numbers vary by sub-year
The FB25 has been revised across three Outback generations (BR, BS, and the current model). Oil pan design, filter type (cartridge vs spin-on) and a running switch toward thinner 0W-20 oil all affected the stated capacity, which is why service sources do not fully agree on the 2010-2014 figures - treat that row as a range rather than a single number until you check your own placard.

Frequently asked questions
Does the Outback take synthetic oil or conventional oil?
Newer Outbacks (FB25 from roughly 2010 onward and the FA24 turbo) are factory-filled with 0W-20 synthetic oil. Older EJ25 and EZ36-powered Outbacks specified 5W-30, which was commonly conventional but synthetic 5W-30 is also acceptable and often recommended today.
Is the oil capacity the same for the turbo and non-turbo 2.5L Outback?
No. The 2.4L turbo FA24 (2020-present) takes roughly 4.5 L / 4.8 US qt with a filter change, while the naturally aspirated 2.5L FB25 of the same generation takes about 4.2 L / 4.4 US qt. Do not assume the two share a capacity just because they were sold in the same model years.
Why do different sources give different oil capacity numbers for my Outback?
Because the Outback has used at least four distinct oil pan and filter combinations since 2000 (EJ25, FB25 across three sub-generations, FA24, and EZ36), and some listings only specify model year without engine code. When in doubt, use the oil filler cap sticker or the owner's manual, then verify with the dipstick after refilling and running the engine.
How much oil does a 3.6R Outback take?
The 3.6L six-cylinder EZ36 used in the 3.6R trim takes about 6.5 L / 6.9 US qt of 5W-30 with a filter change, noticeably more than the four-cylinder engines due to its larger displacement.
