Differential fluid capacity & service interval

BMW Z1 and Z1 (EU) models require 1,7 liters of differential fluid. Service intervals include checks at 24000 km and changes at 48000 km. The data covers 1 configuration.

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

TypeSpecifications

  • Rear
  • Use: Normal
  • Capacity 1,7 liter
  • Check 24000 km
  • Change 48000 km

Additional Notes

  • The rear differential on the BMW Z1 holds 1.7 liters of fluid, a figure consistent with a service fill rather than a full overhaul capacity, meaning the housing retains residual fluid during a drain and refill procedure.
  • Under normal use conditions, the Z1 (1988-1992) rear differential is specified for a fluid check interval of 24,000 km, placing the inspection at roughly the halfway point between change intervals.
  • The fluid change interval for the rear differential is set at 48,000 km under normal use conditions, which is exactly double the check interval, reflecting a structured two-stage maintenance cycle within a single service period.
