Porsche Cayman, 987 (EU)

Differential fluid capacity & service interval

Porsche Cayman, 987 (EU) differential fluid capacity is 0,8 liter. Service intervals are 180000 km or 144 months. The data covers 2 configurations.

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

TypeSpecifications
  • Cayman (2005-2009)
  • From automatic
  • Use: Normal
  • Capacity 0,8 liter
  • Change 180000 km/ 144 months
  • Cayman S (2005-2009)
  • From automatic
  • Use: Normal
  • Capacity 0,8 liter
  • Change 180000 km/ 144 months

Additional Notes

  • Both the Cayman and Cayman S carry a differential fluid capacity of 0.8 liter, which is a relatively modest fill volume consistent with a compact rear differential unit rather than a full transaxle overhaul quantity.
  • The 0.8 liter figure applies specifically to the differential sourced from the automatic transmission assembly, as noted in the specifications for both variants across the 2005-2009 model years.
  • Under normal use conditions, the Porsche Cayman 987 (EU) differential fluid change interval is set at 180,000 km or 144 months, whichever comes first, reflecting a long-life service schedule.
  • 144 months translates to 12 years, meaning the time-based interval is quite extended and would be the governing limit for lower-mileage vehicles that do not reach the 180,000 km threshold within that period.
  • The Cayman and Cayman S share identical differential fluid capacity and service interval values across the full 2005-2009 span, indicating no differentiation in differential service requirements between the base and S variants despite their differing engine outputs.
