Additional Notes
- The Opel Senator B, V88 rear differential fluid capacity falls into one of two values across all listed engine variants: 1.2 liters for the 2.5i and 3.0i, and 1.1 liters for the 2.6i and 3.0i 24V.
- The 1.2-liter capacity figure applies to the Senator 2.5i (1987-1993) and Senator 3.0i (1987-1993), both sharing an identical rear differential fill volume under normal use conditions.
- The Senator 2.6i (1990-1993) and Senator 3.0i 24V (1989-1993) each carry a 1.1-liter rear differential capacity, a value that holds regardless of whether the unit is a standard differential or a limited-slip variant.
- The limited-slip differential configurations listed for the 2.6i and 3.0i 24V share the same 1.1-liter capacity as the standard rear differential in those same engine variants, meaning the limited-slip designation does not alter the fluid volume specification.
- All six configurations across the Senator B, V88 range share a uniform service interval of 15,000 km or 12 months, whichever comes first, applied under normal use conditions.
- The service action specified at the 15,000 km or 12-month interval is a fluid level check rather than a full fluid change, which is a maintenance distinction relevant to service planning for all listed variants.
- The 3.0i 24V variant, introduced in 1989-1993, uses a 1.1-liter rear differential capacity, while the earlier 3.0i from 1987-1993 requires 1.2 liters, representing a capacity difference between two variants sharing the same displacement figure.
