Additional Notes

  • The Vauxhall Cavalier III (J89) rear differential fluid capacity is 0.8 liter across all four 4WD configurations listed, which is a relatively small volume consistent with a compact rear differential unit rather than a larger axle assembly requiring a full overhaul fill.
  • The 1.8S 4WD, 2.0i 4WD, and 2.0i-16V 4WD variants share an identical rear differential check interval of 15,000 km or 12 months under normal use conditions, whichever comes first.
  • The 2.0i-16V Turbo 4WD, covering 1992-1995, carries a notably extended rear differential check interval of 30,000 km or 24 months under normal use conditions, doubling the distance and time thresholds applied to the other three 4WD variants.
  • The divergence in check intervals between the turbocharged and non-turbocharged 4WD variants is not accompanied by any difference in fluid capacity, as all four configurations retain the same 0.8 liter fill.
  • The 2.0i-16V Turbo 4WD is the only configuration with a production window starting in 1992, while the remaining three 4WD variants span the full 1988-1995 period covered by the specifications.
  • A check interval, as opposed to a drain-and-refill interval, means the service action involves inspecting the fluid level and condition rather than a mandatory full fluid replacement at that mileage or time point.
