Additional Notes

  • The Impreza 1.5R with all-wheel drive carries a combined automatic transmission and transfer box fluid capacity of 8.4 liters, while the front-wheel-drive 1.5R variant uses a transaxle-only fill of 8.0 liters, reflecting the absence of a transfer box in the drivetrain.
  • The Subaru Impreza GE/GH 2.5T WRX holds the largest automatic transmission fluid capacity across the range at 9.3 liters, consistent with the higher torque demands placed on the unit by the turbocharged engine.
  • All four configurations share the same fluid check interval of 30,000 km or 24 months under normal use conditions, regardless of engine size or drivetrain layout.
  • The 1.5R variants, both AWD and FWD, carry a change interval of 105,000 km or 84 months under normal use, which is notably longer than the intervals specified for the 2.0R and 2.5T WRX configurations.
  • The Impreza 2.0R and 2.5T WRX share a change interval of 60,000 km or 48 months under normal use, placing the fluid renewal cycle at roughly half the mileage threshold applied to the 1.5R variants.
  • The 2.5T WRX specification covers model years 2007-2011, a narrower production window than the three other configurations, all of which span 2007-2012 or 2008-2012.
  • The AWD 1.5R and FWD 1.5R share the same 105,000 km change interval despite differing in drivetrain layout and total fluid capacity, indicating the interval is tied to the engine and transmission type rather than the presence of a transfer box.
