Additional Notes

  • The Subaru Legacy / Outback 2.2 4WD (BD, BG, BK EU) carries the largest manual transmission fluid capacity in the lineup at 4 liters, reflecting the combined volume of the transaxle and transferbox assembly.
  • Two-wheel-drive variants of the 2.0 and 2.2 engines fill the transaxle only, while all 4WD variants cover both the transaxle and transferbox under a single combined capacity figure.
  • The 2.0 4WD and 2.5 4WD share an identical combined transaxle and transferbox capacity of 3.5 liters, matching the 2.2 two-wheel-drive figure despite the additional transferbox volume in the 4WD units.
  • The 2.0 two-wheel-drive transaxle holds 3.3 liters, which is the lowest capacity value across all five configurations.
  • All five configurations share a uniform fluid change interval of 50,000 km or 24 months under normal use conditions, regardless of drivetrain layout or engine displacement.
  • The 2.2-liter configurations, both two-wheel-drive and 4WD, carry an additional fluid level check interval of 25,000 km or 12 months under normal use conditions, a requirement not present in the 2.0 or 2.5 specifications.
  • The 2.5 4WD variant covers model years 1996-1999, a narrower production window than the 1994-1999 range of the 2.0 configurations and the 1994-1998 range of the 2.2 configurations.
