Additional Notes

  • The BMW 3 Series E30 (USA) 325iX transfer case fluid capacity is specified at 0.45 liter, a figure consistent with a compact transfer case unit rather than a larger drivetrain assembly.
  • The 0.45 liter figure represents a service fill quantity, reflecting the amount of fluid used in a routine drain-and-refill procedure where some residual fluid remains in the unit.
  • The specification carries a normal use condition designation, meaning the listed capacity applies to standard driving circumstances rather than severe use cycles such as frequent towing or extreme temperature operation.
  • No variation in the 0.45 liter capacity is recorded across the 1987-1991 model year span covered by the specifications.
