Additional Notes

  • The BMW Z1 manual transmission holds 1.25 liters of fluid, a figure consistent with the compact gearbox units found in small-displacement rear-wheel-drive sports cars of the late 1980s and early 1990s.
  • A 1.25-liter capacity represents a service fill volume, meaning the amount required when draining and refilling the transmission during routine maintenance rather than a full overhaul, which would typically account for additional fluid retained in passages and components.
  • Under normal use conditions, the Z1 manual transmission fluid is specified for a check interval of 24,000 km, allowing for verification of fluid level and condition at the halfway point before a full change is due.
  • The change interval for the Z1 manual transmission fluid under normal use is set at 48,000 km, exactly double the check interval, reflecting a structured two-stage service approach across the maintenance cycle.
