Subaru Legacy / Outback, BN, BS (USA / CAN)

Additional Notes

• Across all listed configurations of the Subaru Legacy / Outback BN/BS, brake fluid capacity is expressed as a reservoir level range rather than a fixed volume, meaning the specification calls for fluid to sit between the minimum and maximum marks on the reservoir rather than a measured fill quantity.
• Under normal use conditions, the hydraulic brake system across all listed 2.5i and 3.6R configurations carries a change interval of 30,000 miles or 30 months, whichever comes first.
• Under severe use conditions, the same hydraulic brake system interval is halved to 15,000 miles or 15 months across every listed configuration, reflecting the accelerated fluid degradation associated with more demanding operating conditions.
• The 2.5i and 3.6R engine variants share identical brake fluid service intervals under both normal and severe use conditions, indicating no differentiation in brake system maintenance schedules between the four-cylinder and six-cylinder powertrains.
• The 2.5i configurations span three overlapping year groupings — 2014-2015, 2015-2017, and 2017-2019 — each carrying the same interval structure, meaning the 30,000-mile/30-month and 15,000-mile/15-month intervals apply consistently across the full 2014-2019 range for that engine.
• The 3.6R configurations are grouped into two year ranges, 2014-2015 and 2015-2019, both of which carry the same normal and severe interval values as the 2.5i, confirming uniform brake fluid service timing across the six-cylinder lineup within the covered years.
