Additional Notes

  • The Subaru Legacy / Outback BE, BH, BT (EU) 2.0 front-wheel-drive configuration carries an automatic transmission fluid capacity of 7.9 liters, which represents the total system fill volume for the transmission alone.
  • The 2.0 4WD variant shares the same 7.9-liter capacity as the front-wheel-drive 2.0, though the specification note for the 4WD covers both the automatic transmission and the transfer box as a combined figure.
  • The 2.5 4WD variant carries a notably higher capacity of 9.5 liters, also covering the automatic transmission and transfer box together, reflecting the additional fluid volume associated with the larger 2.5-liter drivetrain configuration.
  • Across all three configurations spanning 1998-2004, the service interval is set at 50,000 km or 24 months under normal use conditions, whichever comes first.
  • The 24-month time-based interval alongside the 50,000 km mileage threshold means that lower-mileage vehicles still reach a service point within two years, regardless of distance traveled.
  • All three rows are specified under normal use conditions, meaning the 50,000 km / 24-month interval applies to standard operating circumstances rather than a reduced severe-duty schedule.
