Additional Notes

  • The Subaru Impreza GE/GH (EU) 1.5R AWD variant lists a transaxle and transferbox combined capacity range of 3.5–4 liters. A capacity expressed as a range rather than a fixed value typically reflects variation between the individual transaxle and transferbox fill levels when measured separately or together.
  • The 1.5R FWD variant, covering 2008-2012, carries a fixed transaxle-only capacity of 3.3 liters. The absence of a transferbox on the front-wheel-drive configuration accounts for the lower figure compared to the AWD 1.5R, which lists 3.5–4 liters.
  • The 2.0 D diesel variant, spanning 2008-2012, holds the highest single listed capacity among the AWD configurations at 3.7 liters for the transaxle and transferbox combined. A fixed value here, rather than a range, suggests a more consistent fill specification across that drivetrain.
  • The 2.0R AWD shares the same 3.5–4 liter capacity range and identical service intervals as the 1.5R AWD, despite the difference in engine displacement. Both cover 2007-2012 and carry the same transaxle and transferbox note.
  • The 2.5T WRX and 2.5T WRX STI, both spanning 2007-2011, each list two separate capacity entries: 3.5 liters and 4.1 liters. These two figures represent different transaxle unit variants fitted to the same model, as both rows carry the same transaxle-only note without a transferbox reference.
  • The 4.1-liter capacity listed for both the WRX and WRX STI is the largest fixed capacity value across all configurations in the range. Transaxles with higher fluid volumes generally correspond to units with greater internal component mass or additional gear sets.
  • All eight rows share a uniform service schedule: 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-unit intervals mean the time-based trigger applies when the distance threshold has not been reached, which is relevant in lower-mileage usage patterns.
  • All entries are designated for normal use conditions. No severe-use intervals are listed for any configuration within the 2007-2012 Impreza GE/GH EU manual transmission fluid specifications.
