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

Additional Notes

• The front differential coupled to the CVT carries a 1.2-liter capacity across all 2.5i configurations from 2014-2019, while the same location on the 3.6R holds 1.4 liters for both the 2014-2015 and 2015-2019 model groups, reflecting the greater fluid volume associated with the six-cylinder drivetrain layout.
• The rear differential capacity is rated at 0.8 liters across every configuration in the Subaru Legacy / Outback BN/BS range covered here, regardless of engine displacement or model year grouping.
• Under normal use conditions, both the front CVT-sourced differential and the rear differential across the 2.5i lineup from 2014-2019 are subject to a check interval of 30,000 miles or 30 months, rather than a fluid change requirement.
• Under severe use conditions, the same 2.5i front and rear differentials shift from a check schedule to an active fluid change at 15,000 miles or 15 months, cutting the service interval in half compared to normal use.
• The 3.6R from 2014-2015 follows the same interval structure as the 2.5i, with a 30,000-mile or 30-month check under normal conditions and a 15,000-mile or 15-month change under severe conditions, applied to both the front CVT differential and the rear differential.
• For the 3.6R covering 2015-2019, the front CVT-sourced differential entry lists only a 1.4-liter capacity under normal use, with no interval value recorded in the specifications for that position.
• The rear differential on the 3.6R from 2015-2019 retains the same interval structure seen in earlier configurations, with a check at 30,000 miles or 30 months under normal use and a change at 15,000 miles or 15 months under severe use.
