Additional Notes
- All six 4x4 configurations of the Opel Calibra C89 share an identical rear differential fluid capacity of 0.8 liter, a relatively modest figure consistent with a compact rear differential unit rather than a larger axle assembly.
- The 0.8 liter capacity figure represents a service fill level, meaning the quantity of fluid required during a standard drain-and-refill procedure under normal operating conditions.
- A check interval of every 15,000 km or 12 months under normal use applies uniformly across all listed configurations, meaning fluid level and condition are to be inspected annually or at each major service visit, whichever comes first.
- The change interval of 45,000 km or 36 months under normal use means the rear differential fluid is renewed every three years or three standard service cycles, whichever milestone is reached first.
- The 2.0i 16V Turbo 4x4 variant, available from 1992, carries the same 0.8 liter rear differential capacity and identical check and change intervals as the naturally aspirated 4x4 variants, indicating no differentiation in rear differential servicing requirements between the turbocharged and non-turbocharged drivetrains.
- Across the 1990-1994 and 1994-1998 production periods, the rear differential specifications remain unchanged for each respective variant, meaning no revision to capacity or service intervals occurred at the 1994 model year transition.
