Subaru Impreza, GJ, GP (EU)

Brake fluid capacity & service interval

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

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

Additional Notes

  • Across all configurations of the Subaru Impreza GJ/GP (EU), brake fluid level is specified as "between min and max" rather than as a fixed volume. This phrasing is standard for hydraulic brake systems, where the reservoir is topped to a marked range rather than filled to a precise measured capacity.
  • Under normal use conditions, the brake fluid change interval is set at 30,000 km or 24 months, whichever comes first. The time-based component reflects the hygroscopic nature of brake fluid, which absorbs moisture from the atmosphere over time regardless of mileage accumulated.
  • Under severe use conditions, the change interval is halved to 15,000 km or 12 months. Severe use typically involves more frequent or intense braking cycles, which accelerates fluid degradation through heat exposure and increases the rate at which moisture contamination affects braking performance.
  • The 1.6i and 1.6i FWD variants for 2013-2014 and 2015-2016 share identical brake fluid intervals under both normal and severe conditions, indicating no differentiation in hydraulic system service requirements between the all-wheel-drive and front-wheel-drive drivetrains at this engine displacement.
  • The 2.0i variants covering 2012-2014 and 2015-2016 carry the same 30,000 km/24-month normal interval and 15,000 km/12-month severe interval as the 1.6i configurations, showing consistency in brake fluid service scheduling across both engine displacements within the GJ/GP generation.
  • The year groupings of 2013-2014 and 2015-2016 for the 1.6i variants, compared to 2012-2014 for the 2.0i, reflect differences in when each engine variant entered the EU market lineup rather than any change in the underlying brake fluid service specifications.
