Additional Notes
- The BMW Z4 Coupé E86 (USA) 3.0si carries an automatic transmission fluid capacity of 9 to 9.5 liters under normal use conditions, placing it in the upper range typical of six-speed automatic units found in rear-wheel-drive sport configurations of that era.
- The 0.5-liter spread between the lower and upper capacity figures for the 3.0si reflects the standard variance encountered during a service fill, where residual fluid retained in the torque converter and valve body accounts for the difference between a dry overhaul fill and a routine drain-and-refill procedure.
- The normal use condition tied to the 9 to 9.5-liter specification applies to the full 2005-2008 model year span of the Z4 3.0si, with no separate interval or capacity figure listed for severe use conditions.
