Subaru WRX, GR, GV (EU)

Manual transmission fluid capacity & service interval

Subaru WRX, GR, GV (EU) manual transmission fluid capacity ranges from 3,5 to 4,1 liters. Service intervals include checks every 30000 km or 24 months and changes every 60000 km or 48 months. The data covers 2 configurations.

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

Additional Notes

  • The Subaru WRX (EU) Impreza 2.5T WRX STI carries a manual transaxle fluid capacity of 4.1 liters, which is notably larger than the 3.5-liter capacity specified for the standard Impreza 2.5T WRX, reflecting the STI's heavier-duty gearbox construction.
  • Both the 2.5T WRX and 2.5T WRX STI share identical service interval structures across the 2011-2014 model years, with a fluid check interval of 30,000 km or 24 months and a full fluid change interval of 60,000 km or 48 months under normal use conditions.
  • The check interval of 30,000 km or 24 months represents a mid-cycle inspection point, occurring at exactly half the distance and time of the full change interval, meaning two check cycles align with one complete fluid change cycle for both configurations.
  • Both transaxle specifications are designated for normal use conditions, meaning the 60,000 km or 48-month change interval applies to standard operating environments rather than demanding or high-stress driving scenarios.
  • The 0.6-liter difference in fluid capacity between the standard WRX and the WRX STI transaxles indicates a physically distinct gearbox unit in the STI, as fluid volume in a manual transaxle is directly tied to the internal volume of the housing and gear assembly.
