Subaru Impreza, GE, GH (EU)

Brake fluid capacity & service interval

Subaru Impreza, GE, GH (EU) models utilize brake fluid with a capacity range between min and max. Service intervals include 15000 km/12 months, 25000 km/12 months, 30000 km/24 months, and 50000 km/24 months. The data covers 9 configurations.

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

Additional Notes

  • Across all Subaru Impreza GE/GH (EU) variants in the 2007-2012 range, the brake fluid fill level is specified as "between min and max" rather than a fixed volume. This approach is standard for hydraulic brake system servicing, where the reservoir is topped to the marked range rather than filled to a precise measured quantity.
  • The 1.5R and 1.5R FWD variants share identical interval structures: 30,000 km or 24 months under normal use conditions, and 15,000 km or 12 months under severe use conditions. The halving of both the distance and time thresholds under severe conditions reflects the accelerated fluid degradation associated with more demanding operating environments.
  • The 2.0R carries a notably longer normal-use interval of 50,000 km or 24 months, compared to the 30,000 km or 24 months specified for the 1.5R. While the time component remains the same at 24 months, the distance threshold is considerably higher, meaning the calendar limit will govern more frequently in lower-mileage use.
  • Under severe use conditions, the 2.0R interval is specified at 25,000 km or 12 months, which maintains the same halving ratio seen in the 1.5R severe-use reduction, cutting both the distance and time thresholds by half relative to the normal-use figures.
  • The 1.5R FWD, introduced in 2008, carries the same interval specifications as the all-wheel-drive 1.5R across both normal and severe use conditions, indicating no differentiation in brake fluid service requirements between the two drivetrain configurations at this engine displacement.
  • The Impreza 2.0 D (2008-2012), 2.5T WRX (2007-2011), and 2.5T WRX STI (2007-2011) each list only the fill level specification with no change interval recorded. No severe-use rows are present for any of these three variants.
  • The 2.5T WRX and 2.5T WRX STI share the same single normal-use row structure, with no distinction in brake fluid specifications between the standard WRX and the higher-performance STI variant within the 2007-2011 period.
