Additional Notes

  • The front differential on the Porsche 911 Carrera 4, 964 holds 1.2 liters of fluid, a figure that reflects a service fill capacity for a compact front differential unit integrated into the all-wheel-drive system.
  • The check interval for the front differential fluid is set at 20,000 km or 12 months, whichever comes first under normal use conditions.
  • A full fluid change is specified at 80,000 km or 48 months under normal use conditions, meaning the change interval is four times longer than the check interval on a mileage basis.
  • The 12-month check cycle and 48-month change cycle run in parallel with the mileage thresholds, so whichever limit is reached first would apply in real-world service scheduling.
