Additional Notes

  • The rear differential fluid capacity across all Jaguar XJ X308 variants — the XJ8 3.2, XJ8 4.0, and XJR — is uniformly 1.9 liters throughout the 1997-2003 model range. A capacity in this range is typical of a rear differential service fill, representing the working fluid volume held within the differential housing under normal operating conditions.
  • Under normal use conditions, the rear differential fluid check interval is set at 16,000 km or 12 months, whichever comes first. The dual-trigger format means the interval is governed by both distance and elapsed time, so low-mileage vehicles still require a check on an annual basis.
  • Under severe use conditions, the time-based check interval is reduced to every 6 months across all X308 variants and both production sub-periods. No distance figure is specified for severe use, making the interval purely time-driven rather than mileage-driven.
  • The 1.9-liter capacity figure remains unchanged between the earlier 1997-2001 production period and the later 2001-2003 period for all three variants. The continuity in capacity across both sub-periods indicates no mechanical revision to the rear differential housing or fill volume specification occurred at the 2001 production changeover.
  • The XJR shares the same 1.9-liter rear differential capacity and identical check intervals as the XJ8 3.2 and XJ8 4.0, despite the XJR being a supercharged performance variant. The differential fluid service schedule does not reflect any differentiation based on engine output or drivetrain loading in these specifications.
  • The split of the model range into 1997-2001 and 2001-2003 sub-periods applies consistently across all three variants. Both sub-periods carry the same capacity and interval values, meaning the year-range division in the specifications represents a production classification rather than a change in service requirements.
