Subaru XT Coupé (EU)

Differential fluid capacity & service interval

Subaru XT Coupé (EU) differential fluid capacity ranges from 0,8 to 1,3 liters. Service intervals include checks at 25000 km or 12 months and changes at 50000 km or 24 months. The data covers 4 configurations.

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

Additional Notes

  • The Subaru XT Coupé (EU) differential fluid specifications cover two distinct drivetrain configurations across the 1985-1993 model range: the standard 1.8 Turbo with a single differential sourced from the automatic transmission, and the 1.8 Turbo 4WD, which carries up to three separate differential fluid service points.
  • The front differential on both the 1.8 Turbo and the 1.8 Turbo 4WD is shared with the automatic transmission housing, holding 1.3 liters of fluid under normal use conditions. A capacity at this level is typical of a transaxle-integrated differential rather than a standalone unit.
  • The rear differential on the 4WD variant holds 0.8 liters, which is a notably smaller volume and reflects the compact, dedicated nature of a rear axle differential as opposed to a combined transaxle assembly.
  • The 4WD model lists a separate rear limited-slip differential entry, also rated at 0.8 liters under normal use conditions. A limited-slip differential requires fluid specifically formulated to interact correctly with its clutch packs or friction surfaces, making the capacity figure relevant to fluid type selection as well as volume.
  • All four rows share an identical check interval of 25,000 km or 12 months under normal use conditions, regardless of differential type or drivetrain layout.
  • The change interval across all listed configurations is 50,000 km or 24 months under normal use conditions, meaning the fluid replacement cycle is set at exactly double the inspection interval in both distance and time terms.
