Subaru Forester, SK (EU)

Differential fluid capacity & service interval

Subaru Forester, SK (EU) differential fluid capacity ranges from 0,8 to 1,37 liters. Service intervals include checks every 30000 km or 24 months and changes every 60000 km or 48 months. The data covers 6 configurations.

Additional Notes

  • Across all three engine variants of the Subaru Forester SK (EU), the rear differential carries a uniform fluid capacity of 0.8 liter, indicating a consistent housing size regardless of powertrain configuration.
  • The front differential, fed directly from the CVT, shows capacity variation by engine type. The 2.5i carries 1.2-1.3 liters, the 2.0i carries 1.21-1.31 liters, and the 2.0i e-Boxer carries the largest range at 1.27-1.37 liters.
  • Capacity figures expressed as ranges rather than fixed values reflect the practical reality of a drain-and-refill service, where residual fluid retained in passages and seals means the exact refill volume falls within a band rather than at a single point.
  • The front differential on the 2.0i e-Boxer sits at a slightly higher capacity range compared to the standard 2.0i, a difference attributable to the hybrid drivetrain's modified CVT and associated differential housing geometry.
  • All six configurations share identical service intervals under normal use conditions: a fluid level check at 30,000 km or 24 months, and a full fluid change at 60,000 km or 48 months.
  • The dual-trigger interval structure, combining a distance threshold with a time threshold, means whichever limit is reached first governs the service event, accommodating both high-mileage and low-mileage usage patterns within the same schedule.
  • The check interval at 30,000 km or 24 months falls at exactly the midpoint of the change interval, meaning one inspection occurs between each successive fluid change across all listed configurations.
  • All specifications are designated for normal use conditions, meaning the stated intervals apply to standard operating environments rather than severe-duty cycles such as frequent towing, off-road use, or extreme temperature exposure.
