Subaru WRX, VB (USA / CAN)

Clutch fluid capacity & service interval

Subaru WRX, VB (USA / CAN) clutch fluid capacity is between min and max. Service intervals include 30000 miles/ 30 months and 15000 miles/ 15 months. The data covers 2 configurations.

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

TypeSpecifications
WRX 2.4T (2021- )
  • Use: Normal
  • Between min and max.
  • Change 30000 miles/ 30 months
WRX 2.4T (2021- )
  • Use: Severe
  • Between min and max.
  • Change 15000 miles/ 15 months

Additional Notes

  • The Subaru WRX VB (2021- ) uses a hydraulic clutch system, meaning clutch fluid is stored in a dedicated reservoir and must be maintained between the marked minimum and maximum levels rather than filled to a fixed volume.
  • Because the reservoir fill level is defined by min and max markers rather than a precise capacity figure, the service specification does not express a discrete fluid volume in quarts or milliliters.
  • Under normal use conditions, the clutch fluid change interval is set at 30,000 miles or 30 months, whichever comes first.
  • Under severe use conditions, the clutch fluid change interval is reduced to 15,000 miles or 15 months, exactly half the normal-use interval in both distance and time.
  • The parallel halving of both the mileage and time thresholds between normal and severe conditions reflects a consistent ratio across the two interval dimensions, keeping the distance-to-time relationship identical at 1,000 miles per month in each case.
