Jaguar XK, X100 (USA)

Power steering fluid capacity & service interval

Jaguar XK, X100 (USA) models require power steering fluid with a capacity of 1 liter. Service intervals include checking every 10000 miles or 12 months, or every 6 months. The data covers 11 configurations.

Additional Notes

  • The Jaguar XK X100 power steering system holds a uniform 1 liter capacity across all listed configurations, spanning the XK8 and XKR variants from 1996-2006. A 1-liter figure is typical of a hydraulic power steering reservoir service fill, representing the fluid volume held in the reservoir and circuit rather than a full system overhaul quantity.
  • Under normal use conditions, all listed XK8 and XKR configurations share a check interval of 10,000 miles or 12 months, whichever comes first. The dual-trigger format means the interval resets on whichever threshold is reached earliest, accommodating both high-mileage and low-mileage driving patterns within a calendar year.
  • Under severe use conditions, the check interval shortens to every 6 months, with no mileage figure attached. A time-only interval without a mileage component is common when operating conditions place stress on fluid quality independent of distance traveled, such as frequent short trips, extreme temperatures, or sustained low-speed operation.
  • The XK8 4.0 V8 rated at 216 kW spans three distinct model year groupings in the specifications: 1996-1997, 1998-2000, and 2001-2002. Despite the separate groupings, the power steering capacity and check intervals remain identical across all three periods, indicating no service specification change accompanied the production year divisions.
  • The XK8 transitions from the 4.0 V8 to a 4.2 V8 rated at 224 kW for the 2003-2006 period. The power steering capacity remains at 1 liter, and the normal-use check interval of 10,000 miles or 12 months is unchanged from the earlier 4.0 engine variants.
  • The XKR 4.0 V8 produces 276 kW compared to the XK8 4.0 V8 at 216 kW, a difference attributable to supercharging on the XKR. Despite the higher output, the power steering fluid capacity and service intervals are identical to the naturally aspirated XK8 across equivalent model years.
  • No severe-use interval is listed for the XK8 4.2 V8 (2003-2006), whereas severe-use entries appear for the XK8 4.0 V8 across all three of its year groupings and for the XKR 4.0 V8 in both of its year groupings.
