PRODUCT DETAILS
Which Motor Oil for the Subaru Outback?
The Subaru FB boxer requires a fully synthetic 0W20 from the factory; however, if the car consumes oil, a thicker 5W50 (film strength) brings a clear benefit, and if it does not, 5W30 offers balanced protection. Both are offered in the kit as Brava Extreme 9000 fully synthetic.
Subaru Outback Oil Capacity
- Engine: 2.5 Boxer (FB25) — crossover/estate
- Oil capacity: ~4.8 L (with filter; may vary by engine code)
- Factory viscosity: 0W20 · 5W30/5W50 when consuming oil
- Kit: 5 L Extreme 9000 + A980 NanoComplex 300 ml
Subaru Outback Oil Burning and Oil Consumption Problem
The 2.5 Boxer (FB25) engine of the Subaru Outback (2013-2014, crossover/estate) is known for the excessive oil consumption familiar from Subaru's FB series boxer engines. The cause is early wear/sticking of the oil control rings: oil escapes into the combustion chamber and burns. Subaru officially acknowledged this problem and replaced rings/short blocks on affected 2011-2014 models. In the flat boxer layout the rings are exposed to more oil under gravity, so consumption becomes more pronounced. The correct viscosity + additive is critical in bringing consumption under control.
Oil Burning Prevention Kit for the Subaru Outback
- Subaru Outback that consumes oil → 5 L Brava Extreme 9000 5W50 + A980 NanoComplex — a thicker film that noticeably reduces oil escaping past the boxer rings and cuts consumption.
- No consumption / protection → 5 L Brava Extreme 9000 5W30 + A980 NanoComplex.
The kit contains 5 litres (capacity ~4.8 L, with a reserve). Note: Subaru recommends 0W20 from the factory; when a car consumes oil, a thicker 5W30/5W50 noticeably reduces consumption.
How Does A980 NanoComplex Reduce Oil Consumption?
It strengthens the oil film and reduces oil escaping past worn/stuck oil control rings, cuts oil passage into the combustion chamber and noticeably reduces consumption. It protects the cylinders in both banks of the boxer engine.
Other Common Problems of the Subaru Outback
- Oil control ring wear (the root cause): On the FB boxer the rings wear or stick early. The permanent fix is renewing the rings/short block, which is a job for an authorised service centre; the correct oil + A980 noticeably reduces consumption and slows its progress.
- Head gasket (especially the older EJ boxer): Gasket leaks are classic on boxer engines — coolant/oil leaks should be checked (authorised service).
- PCV / crankcase ventilation: A faulty PCV increases consumption; it is a relatively affordable repair.
- Timing chain: The FB is chain-driven — do not neglect maintenance; clean oil maintains chain tension.
Note: This kit targets the oil side of the Subaru Outback (consumption control + protection); mechanical repair of rings or gaskets is a job for an authorised service centre.
Subaru Outback Oil Burning Symptoms
- Low oil level warning light (usually 1 L low)
- A visible oil level drop every 1,500-2,000 km
- Slight blue smoke from the exhaust
- A smell of oil / oil-fouled spark plugs

Frequently Asked Questions
Why does the Subaru Outback burn oil?
On FB series boxer engines, early wear/sticking of the oil control rings lets oil into the combustion chamber; Subaru acknowledged the problem and carried out repairs on 2011-2014 models.
Which oil does the Subaru Outback use?
Factory fill 0W20; when a car consumes oil, 5W30/5W50 is more helpful. The kit contains Brava Extreme 9000 (5W50/5W30) + A980.
What is the oil capacity of the Subaru Outback?
Approximately 4.8 litres (with filter; varies by engine code); the kit contains 5 litres (with a reserve).
What did Subaru do about oil burning on the Subaru Outback?
On affected series, Subaru replaced the oil control rings (in some cases the short block). Before that, consumption can be managed with the correct oil + A980.
Will this kit completely end oil burning on the Subaru Outback?
Unless there is severe ring damage it reduces consumption substantially; with advanced damage, service intervention is required.
