Additional Notes

  • The Porsche 912 (EU) carries a manual transaxle fluid capacity of 2.5 liters, which reflects a combined gearbox and differential housing typical of rear-engine Porsche transaxle designs from the 1960s, where a single shared sump serves both functions.
  • The specified change interval for the manual transaxle fluid is 10,000 km, applied under normal use conditions across the full 1965-1969 model range.
  • A 2.5-liter capacity in a transaxle of this era is consistent with a service fill volume, meaning the amount required when draining and refilling during a routine fluid change rather than a full overhaul with complete disassembly.
