Additional Notes

  • The Opel Combo E automatic transaxle carries a dry fill capacity of 7 liters across all listed configurations, which represents the total fluid volume required when filling a completely drained or newly assembled unit.
  • The service fill capacity for the 1.5 Diesel (96 kW) is a fixed 3 liters, reflecting the amount of fluid exchanged during a routine drain-and-refill procedure rather than a full overhaul.
  • The 1.2 Turbo (96 kW) has a service fill range of 2.5-3.5 liters, which is a wider tolerance compared to the fixed 3-liter figure specified for the 1.5 Diesel, indicating some variability in the amount of residual fluid retained in the transaxle between services.
  • Despite the difference in engine type between the 1.2 Turbo and the 1.5 Diesel, both share the same 7-liter dry fill capacity, pointing to the use of the same automatic transaxle unit across those two powertrains.
  • The 1.5 Diesel (96 kW) appears under two separate specification entries, one covering 2018-2021 and one starting from 2021, both under normal use conditions and both with identical dry and service fill capacities of 7 liters and 3 liters respectively.
  • All three rows are designated for normal use conditions, meaning the listed capacities apply to standard operating environments rather than severe-duty cycles such as frequent towing or extreme temperature exposure.
