Additional Notes

  • The Jaguar XJ (X350, X358) rear differential holds 1.25 liters of fluid across all four configurations covered in the specifications: the XJ6 3.0, XJ8 3.5, XJ8 4.2, and XJR 4.2 SC.
  • A 1.25-liter capacity is consistent with a service fill figure, meaning the amount required when topping up or refilling a unit that remains installed in the vehicle, rather than a full overhaul or bench-fill quantity.
  • The check interval for all four configurations is set at 16,000 km or 12 months, whichever comes first, under normal use conditions.
  • A 16,000 km or 12-month check interval for rear differential fluid under normal use reflects a relatively routine inspection schedule, intended to verify fluid level and condition rather than necessarily mandate a full fluid exchange at each interval.
  • The XJR 4.2 SC, which carries a supercharged engine, shares the same 1.25-liter rear differential capacity and 16,000 km / 12-month check interval as the naturally aspirated XJ6 3.0, XJ8 3.5, and XJ8 4.2 variants across the 2003-2006 model years.
