Additional Notes

  • The Porsche Boxster 981 (EU) manual transaxle fluid capacity splits into two distinct values across the lineup: the base Boxster (2012-2016) holds 3 liters, while the Boxster S (2012-2016) and Boxster GTS (2015-2016) each hold 3.2 liters.
  • The Boxster Spyder (2015-2016) carries a capacity range of 3.2-3.3 liters for the manual transaxle, which is the only variable fill figure across the entire 981 EU manual transmission lineup.
  • A transaxle layout, as noted across all four configurations, places the transmission and differential in a single combined unit at the rear axle, which is why the fluid capacity is treated as one service fill rather than separate gearbox and differential volumes.
  • All four configurations share an identical service interval of 180,000 km or 144 months (12 years), whichever comes first, under normal use conditions.
  • The 144-month time limit means that even low-mileage vehicles driven well under 180,000 km are subject to a fluid change once 12 years have elapsed under normal use conditions.
  • All interval and capacity specifications across the 981 EU manual transmission apply exclusively to normal use conditions, with no separate severe-use interval listed for any configuration.
  • The Boxster GTS and Boxster Spyder variants both appear only within the 2015-2016 portion of the 981 generation, while the base Boxster and Boxster S span the full 2012-2016 range.
