Subaru WRX, GR, GV (EU)

Power steering fluid capacity & service interval

Subaru WRX, GR, GV (EU) models require power steering fluid with a capacity of 0,7 liter. Service intervals consist of checks every 24 months or 30000 km and every 15000 km or 12 months. The data covers 4 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 and Impreza 2.5T WRX STI both share an identical power steering fluid capacity of 0.7 liter across the 2011-2014 model years, indicating no volumetric difference between the standard and STI variants for this system.
  • A 0.7 liter capacity is a relatively modest figure for a hydraulic power steering reservoir, consistent with a service-level top-up or inspection fill rather than a full system overhaul volume.
  • Under normal use conditions, the power steering fluid check interval for the Impreza 2.5T WRX is set at 24 months or 30,000 km, whichever comes first.
  • Under severe use conditions, the same Impreza 2.5T WRX requires a power steering fluid check at a significantly shorter interval of 15,000 km or 12 months, reflecting the increased stress placed on hydraulic systems under demanding driving conditions.
  • The Impreza 2.5T WRX STI follows the same interval structure as the standard WRX, with a 24-month or 30,000 km check under normal use and a 15,000 km or 12-month check under severe use, despite the STI's higher-performance character.
