Subaru Crosstrek, GU (USA / CAN)

Differential fluid capacity & service interval

Subaru Crosstrek, GU (USA / CAN) differential fluid capacity ranges from 0,8 to 1,3 liters. Service intervals include checking every 30000 miles or 30 months and changing every 15000 miles or 15 months. The data covers 4 configurations.

Additional Notes

  • The front differential on the Subaru Crosstrek GU 2.0i, sourced from the CVT unit, holds 1.3 liters of fluid, a capacity figure associated with an integrated transaxle-style differential rather than a standalone housing.
  • The rear differential on the 2.0i carries 0.8 liters, which is roughly 38 percent less fluid volume than the front CVT-sourced differential, reflecting the smaller, dedicated rear drive unit typical of all-wheel-drive crossovers.
  • Under normal use conditions, both the front CVT-sourced differential and the rear differential share the same inspection interval of 30,000 miles or 30 months, whichever comes first, with no fluid change specified at that point.
  • Under severe use conditions, both differentials require a fluid change at 15,000 miles or 15 months, exactly half the distance and time of the normal-use inspection interval, indicating a significantly accelerated service schedule when operating demands are higher.
  • The distinction between a check interval under normal use and a change interval under severe use means the fluid is not necessarily replaced on a fixed schedule in everyday driving, only inspected, whereas severe conditions trigger mandatory replacement at the shorter interval.
