Additional Notes

  • The Porsche Boxster 987 (EU) differential fluid capacity is 0.8 liter across all four configurations covered, applying specifically to the differential sourced from the automatic transmission.
  • A capacity of 0.8 liter is a relatively small fill volume, consistent with a compact integrated differential unit rather than a standalone axle housing, which would typically require a larger quantity of fluid.
  • All four configurations share an identical service interval of 180,000 km or 144 months, whichever comes first, under normal use conditions.
  • 144 months translates to 12 years, making the time-based interval notably long and reflecting the low-stress operating environment of a differential fluid in normal driving conditions.
  • The Boxster and Boxster S variants follow the same 0.8 liter capacity and 180,000 km / 144-month interval, indicating no differentiation in differential fluid service requirements between the two trim levels despite their differing engine displacements.
  • Coverage spans two overlapping production sub-ranges, 2005-2006 and 2006-2009, for both the Boxster and Boxster S, with 2006 appearing in both ranges as a transitional model year.
