Subaru Forester, SF (EU)

Manual transmission fluid capacity & service interval

Subaru Forester, SF (EU) manual transmission fluid capacity ranges from 3,5 to 4 liters. Service intervals include checks every 25000 km or 12 months and changes every 50000 km or 24 months. The data covers 3 configurations.

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

Additional Notes

  • The Subaru Forester SF (EU) 2.0 naturally aspirated variant from 1997-1998 carries a 4-liter manual transaxle and transfer box fluid capacity, and I note the specification labels the assembly as a transaxle rather than a standalone transmission unit.
  • For the 1997-1998 2.0, a fluid level check interval of every 25,000 km or 12 months is specified alongside the change interval, making it the only configuration in the SF range to carry a dedicated check interval within these specifications.
  • The change interval across all three SF configurations is uniform at 50,000 km or 24 months under normal use conditions, meaning none of the variants call for more frequent replacement under standard driving circumstances.
  • The 1999-2002 naturally aspirated 2.0 retains the 4-liter capacity of the earlier 1997-1998 variant, though the assembly is reclassified in the specifications from a transaxle to a transmission and transfer box.
  • The turbocharged Forester 2.0 T from 1999-2002 carries a reduced manual transmission and transfer box fluid capacity of 3.5 liters, which is 0.5 liters less than the naturally aspirated 2.0 of the same model years.
  • The capacity difference between the 2.0 and 2.0 T variants sharing the 1999-2002 production window indicates the two configurations use mechanically distinct transmission assemblies despite sharing the same change interval and use condition.
