Jaguar XK, X150 (EU)

Brake fluid capacity & service interval

Jaguar XK, X150 (EU) models require brake fluid with a capacity range between min and max. Service intervals include a check every 24000 km or 12 months and a change every 24 months. The data covers 6 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • All six configurations of the Jaguar XK X150 (EU) covered here share identical brake fluid service intervals: a check every 24,000 km or 12 months, whichever comes first, and a full fluid change every 24 months.
  • The 24-month change interval is time-based rather than mileage-based. Brake fluid absorbs moisture over time, which lowers its boiling point, so calendar time is the governing factor for replacement regardless of distance driven.
  • All specifications apply under normal use conditions, meaning the intervals listed are not adjusted for high-stress driving scenarios such as track use or repeated heavy braking.
  • The fluid level specification of "between min and max" applies to the brake fluid reservoir rather than a fixed fill volume. Reservoir-based level checks are standard for hydraulic brake systems with ABS, where the fluid level naturally drops slightly as brake pads wear.
  • Every variant listed, spanning the naturally aspirated XK 5.0 V8 and the supercharged XKR 5.0 V8 SC and XKR-S 5.0 V8 SC, carries the same check and change schedule, indicating no differentiation in brake fluid servicing across engine output levels within the X150 range.
  • The XKR-S 5.0 V8 SC specifications begin with the 2012-2013 model years, while the XK and XKR variants have entries starting from 2009-2013, reflecting the later introduction of the XKR-S within the X150 generation.
  • All configurations are noted as covering a hydraulic brake system with ABS. ABS systems use the same fluid circuit as the primary hydraulic brakes, so a single reservoir and change interval governs both functions.
