Additional Notes

  • The Vauxhall Senator B, V88 rear differential capacity falls into one of two values across all listed configurations: 1.2 liters or 1.1 liters, depending on the engine variant.
  • The Senator 2.5i (1987-1993) and Senator 3.0i (1987-1993) share the larger 1.2-liter rear differential capacity, placing them in the higher fill group among the listed variants.
  • The Senator 2.6i (1990-1993), Senator 3.0i 24V (1989-1993), and their respective limited slip differential versions all carry a 1.1-liter capacity, which is 0.1 liters less than the 2.5i and 3.0i standard units.
  • A capacity figure in a differential service context typically represents a service fill level, meaning the amount of fluid required when draining and refilling during routine maintenance rather than a full overhaul or bearing replacement procedure.
  • All six configurations share an identical service interval: a fluid level check every 15,000 km or 12 months under normal use conditions, whichever comes first.
  • The 15,000 km or 12-month check interval applies specifically to normal use conditions across every listed configuration, meaning no separate interval is specified for any variant under differing operating conditions.
  • The Senator 2.6i (1990-1993) appears in two separate entries: one for a standard rear differential and one for a rear limited slip differential. Both share the same 1.1-liter capacity and the same 15,000 km or 12-month check interval.
  • The Senator 3.0i 24V (1989-1993) similarly has two entries covering the standard rear differential and the limited slip variant, with both specifying 1.1 liters and the same check interval as the 2.6i counterparts.
  • The presence of limited slip differential entries for the 2.6i and 3.0i 24V variants, but not for the 2.5i or standard 3.0i, reflects a distinction in available differential configurations across the Senator B engine lineup.
