Additional Notes

  • The front-wheel-drive Subaru Legacy / Outback 2.0 (BE/BH/BT, EU) carries a manual transaxle fluid capacity of 3.3 liters, which reflects a standard single-unit transaxle fill without an integrated transfer mechanism.
  • Both the 2.0 4WD and 2.5 4WD variants share a higher capacity of 3.5 liters, accounting for the combined transaxle and transfer box volume serviced as a single fill.
  • The 0.2-liter difference between the front-wheel-drive 2.0 and the 4WD configurations is directly attributable to the transfer box component noted in the 4WD specifications.
  • All three configurations across the 1998-2004 model range share an identical service interval of 50,000 km or 24 months under normal use conditions, whichever comes first.
  • The 24-month time limit alongside the 50,000 km distance interval means fluid age is treated as an independent service trigger, not solely mileage accumulation.
  • The 2.0 and 2.5 4WD variants carry the same 3.5-liter capacity, indicating the transaxle and transfer box assembly volume is consistent regardless of engine displacement in the 4WD lineup.
