Subaru Legacy / Outback, BE, BH, BT (EU)

Differential fluid capacity & service interval

Subaru Legacy / Outback, BE, BH, BT (EU) differential fluid capacity ranges from 0,8 to 1,2 liters. Service intervals occur every 50000 km or 24 months. The data covers 5 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The front differential sourced from the automatic transmission carries a 1.2-liter capacity across the 2.0 and 2.5 engine variants in the Subaru Legacy / Outback BE/BH/BT (EU) range for 1998-2004.
  • The rear differential on 4WD configurations holds 0.8 liter, which is a notably smaller volume than the 1.2-liter front differential fill on the same drivetrain.
  • Both the 2.0 4WD and 2.5 4WD variants share identical rear differential capacity at 0.8 liter, with no variation between the two engine displacements.
  • The 2.0 non-4WD variant lists only a front differential entry at 1.2 liter, with no rear differential specification present for that configuration.
  • All differential service intervals across the 1998-2004 range are set at 50,000 km or 24 months, whichever comes first, under normal use conditions.
  • The 24-month time-based interval running alongside the 50,000 km mileage threshold means a vehicle covering low annual distances would still require a fluid change within two years under normal use.
  • The front differential fluid in all listed configurations originates from the automatic transmission unit, meaning the fluid fill point and service procedure are tied to that assembly rather than a standalone differential housing.
