Additional Notes

  • The Vauxhall VX4/90 rear differential fluid capacity across all four generations falls within a relatively narrow band, ranging from 1.4 liters in the FB and FC series up to 2.27 liters in the FD series, with the FE series sitting at 1.42 liters.
  • The FB (1961-1964) and FC (1964-1967) generations share an identical rear differential fluid capacity of 1.4 liters, along with the same check interval of 9,000 km or every 6 months, whichever comes first.
  • A notable shift occurs with the FD generation (1967-1972), where the rear differential fluid capacity rises to 2.27 liters — the largest figure across all four series — representing a substantial increase over the 1.4-liter figure of the preceding FB and FC generations.
  • The FD generation also marks a change in the check interval, moving from 9,000 km to 20,000 km alongside the 6-month time-based condition, a pattern that carries forward into the FE generation as well.
  • The FE series (1972-1976) rear differential capacity of 1.42 liters is closely aligned with the 1.4-liter figure of the FB and FC generations, despite the FE sharing the longer 20,000 km check interval introduced with the FD.
  • All four generations carry a normal use condition for the rear differential service intervals, meaning the specified check intervals of 9,000 km or 20,000 km apply under standard operating conditions rather than severe or demanding service environments.
  • The dual-condition check interval structure — expressed as both a distance figure and a 6-month time limit — indicates that whichever threshold is reached first would trigger a fluid level inspection, regardless of how the vehicle was used within that period.
