Subaru Impreza, GE, GH (EU)

Differential fluid capacity & service interval

Subaru Impreza, GE, GH (EU) models utilize differential fluid with a capacity range of 0,8 to 1,2 liters. Service intervals include checking every 30000 km or 24 months, and changing every 50000 to 60000 km or 24 to 48 months. The data covers 9 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The front differential (sourced from the automatic transmission unit) holds 1.2 liters across the Subaru Impreza GE/GH 1.5R, 2.0R, and 2.5T WRX variants, a capacity consistent with an integrated differential housing rather than a standalone unit.
  • The rear differential capacity on the 1.5R and 2.0R is 0.8 liters, while the 2.5T WRX STI rear differential holds a notably larger 1.0 liter, reflecting the STI's heavier-duty rear differential assembly designed for higher torque loads.
  • The 1.5R and 2.0 D rear differential shares the same 0.8-liter capacity and identical service intervals, with checks at 30,000 km or 24 months and fluid changes at 60,000 km or 48 months under normal use conditions.
  • The 1.5R front differential (from automatic) follows the same 30,000 km/24-month check interval and 60,000 km/48-month change interval, aligning with the rear differential schedule for that variant.
  • The Impreza 1.5R FWD (2008-2012) retains the 1.2-liter front differential capacity and the same 60,000 km/48-month change interval as the all-wheel-drive 1.5R, despite the absence of a rear differential in the FWD configuration.
  • The 2.0R and 2.5T WRX differential service intervals differ from the 1.5R and 2.0 D: both front and rear differentials on those variants are scheduled for fluid changes at 50,000 km or 24 months, with no separate inspection interval listed.
  • The 2.5T WRX STI rear differential change interval of 50,000 km or 24 months matches the standard 2.5T WRX rear differential schedule, despite the STI unit holding 25% more fluid at 1.0 liter versus 0.8 liters.
  • All specifications across the 1.5R, 2.0 D, 2.0R, 2.5T WRX, and 2.5T WRX STI rows are designated for normal use conditions, meaning the listed intervals apply to standard driving rather than severe or demanding operating environments.
