Subaru E, Libero, Sumo (EU)
Differential fluid capacity & service interval
Subaru E, Libero, and Sumo (EU) models require 0,8 liter of differential fluid. Service intervals include checks every 25000 km or 12 months and changes every 50000 km or 24 months. The data covers 2 configurations.

Additional Notes
- The front differential fluid capacity across both the 1.0 and 1.2 engine variants of the Subaru E, Libero, and Sumo 4WD models is 0.8 liter, a figure consistent with the compact differential housings typical of small-displacement 4WD drivetrains from this era.
- Under normal use conditions, the front differential fluid change interval is set at 50,000 km or 24 months, whichever comes first, applying equally to both the E10/Libero 1.0/Sumo 1.0 and E12/Libero 1.2/Sumo 1.2 4WD configurations across the 1986-2000 model years.
- A separate check interval of 25,000 km or 12 months is specified for the front differential fluid level, placing an inspection point at roughly the halfway mark between each full fluid change service.
- The 0.8 liter capacity figure represents a service fill volume, meaning the amount of fluid required when servicing the differential in a standard maintenance context rather than a complete overhaul or rebuild scenario.
- The 1.0-liter and 1.2-liter 4WD variants share identical front differential fluid capacity and service interval specifications, indicating no differentiation in differential design or servicing requirements between the two engine displacements within the 1986-2000 production span.
