Subaru Crosstrek, GU (USA / CAN)

Brake fluid capacity & service interval

Subaru Crosstrek, GU (USA / CAN) models utilize brake fluid with a capacity range between min and max. Service intervals include changes at 15000 miles/ 15 months and 30000 miles/ 30 months. The data covers 2 configurations.

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

TypeSpecifications
Crosstrek 2.0i (2023- )
  • Use: Normal
  • Between min and max.
  • Change 30000 miles/ 30 months
Crosstrek 2.0i (2023- )
  • Use: Severe
  • Between min and max.
  • Change 15000 miles/ 15 months

Additional Notes

  • The Subaru Crosstrek GU 2.0i brake fluid fill level is specified as between the minimum and maximum marks on the reservoir, rather than as a fixed volume, which is standard for hydraulic brake system servicing where fluid is not drained and refilled in measured quantities.
  • Under normal use conditions, the 2.0i hydraulic brake system carries a change interval of 30,000 miles or 30 months, whichever comes first.
  • Under severe use conditions, the same 2.0i hydraulic brake system requires a change interval of 15,000 miles or 15 months, exactly half the normal-use interval in both distance and time.
  • The alignment between the mileage and month figures across both use conditions follows a consistent ratio of 1,000 miles per month, meaning time and distance triggers are proportionally matched rather than weighted toward one or the other.
