Porsche Cayman, 987 (EU)

Additional Notes

• The Porsche Cayman 987 (EU) manual transaxle specifications list two distinct capacity figures for the 2005-2009 Cayman: a dry fill of 3.2 liters and a service fill of 2.25 liters. A dry fill applies when the unit is completely empty, such as after a full rebuild or replacement, while a service fill reflects the smaller volume needed when residual fluid remains in the housing during a routine drain.
• A second 2005-2009 Cayman row lists a single capacity of 2.8 liters without a dry/service fill distinction, indicating a different transaxle variant within the same model year range that carries a unified fill volume.
• The 2009-2012 Cayman manual transaxle specifies a capacity of 3.0 liters, which sits between the 2.8-liter figure of one earlier Cayman variant and the 3.2-liter figure associated with the Cayman S and Cayman R of overlapping or later years.
• The Cayman S transitions from a 2.8-liter transaxle capacity in the 2005-2009 period to 3.2 liters in the 2009-2012 period, representing a notable increase of 0.4 liters across the generation change.
• The Cayman R (2011-2012) shares the 3.2-liter manual transaxle capacity with the 2009-2012 Cayman S, placing both variants at the upper end of the capacity range seen across all 987 configurations listed.
• All six rows across every Cayman 987 variant and model year share an identical service interval of 180,000 km or 144 months under normal use conditions, meaning the change schedule is uniform regardless of capacity differences between configurations.
• The 144-month time limit on the fluid change interval equals 12 years, which means the time-based threshold can become the governing factor for lower-mileage vehicles before the 180,000 km distance limit is reached.
