Additional Notes

  • The Z4 sDrive28i carries an automatic transmission fluid capacity of 8.5 liters across the 2011-2017 model years, a figure consistent with a full service fill rather than a partial top-up.
  • The Z4 sDrive30i (2008-2011) holds 8.9 liters of automatic transmission fluid, which is 0.4 liters more than the sDrive28i specification.
  • The BMW Z4 Roadster E89 sDrive30i automatic transmission is designated as filled for life under normal use conditions, meaning no scheduled drain-and-refill interval is specified for that configuration.
  • The sDrive28i automatic transmission fluid specification is listed under normal use conditions for all three of its year ranges, 2011-2013, 2013-2015, and 2015-2017, each carrying the same 8.5-liter capacity figure.
  • The capacity difference between the sDrive30i at 8.9 liters and the sDrive28i at 8.5 liters reflects a distinction between two separate transmission units rather than a variation in service procedure for the same unit.
