Additional Notes

  • The Citroën C1 II manual transaxle fluid capacity for the 1.0 VTi 68 CFB engine holds at 1.7 liters across both the 2014-2017 and 2017-2019 production periods, with no variation between the two spans.
  • The 1.0 VTi 72 CFB variant, covering 2018-2021, shares the same 1.7-liter transaxle capacity as the 1.0 VTi 68 CFB, indicating a common gearbox unit across the 1.0-liter engine family in the C1 II.
  • The 1.2 PureTech 82 HMZ engine, produced from 2014-2019, is paired with a manual transaxle specifying two distinct capacity values: a dry fill of 2.1 liters and a service fill of 1.9 liters.
  • A dry fill capacity of 2.1 liters applies when the transaxle is completely empty, as would be the case during a full overhaul or component replacement, while the service fill of 1.9 liters reflects the amount needed when residual fluid remains after a standard drain procedure.
  • The 0.2-liter difference between the dry and service fill figures on the 1.2 PureTech 82 HMZ transaxle is a practical acknowledgment that a routine drain does not evacuate all fluid from internal passages and cavities.
  • All four configurations across the C1 II lineup carry a normal use condition designation, meaning the specified capacities apply under standard operating circumstances rather than severe or first-change-only scenarios.
  • The 1.0-liter VTi engine variants use a notably smaller transaxle capacity of 1.7 liters compared to the 1.9-liter service fill on the 1.2 PureTech 82, reflecting a difference in gearbox size between the two engine families.
