Additional Notes

  • The Jaguar XJS, XJ27 (EU) rear differential holds 1.3 liters of fluid across all listed configurations, a figure consistent with a service fill rather than a full overhaul capacity.
  • The 1.3-liter capacity applies equally to the 4.0-liter inline-six and the 6.0 V12 variants, meaning the rear differential housing size does not differ between the two engine families in the 1991-1994 model years.
  • The same 1.3-liter capacity and 12,000 km / 6-month check interval carry forward without change into the 1995-1997 model years for both the 4.0 and 6.0 V12 variants.
  • The service interval is expressed as a dual condition, 12,000 km or 6 months, whichever comes first under normal use, meaning low-mileage operation does not extend the time-based check beyond six months.
  • All four configurations are rated under normal use conditions, and the 12,000 km / 6-month check interval is tied directly to that classification across the full 1991-1997 span.
