Additional Notes

  • The Vauxhall Astra L manual transaxle fluid capacity varies by engine, with the 1.2 Turbo variants specifying 1.7-1.8 liters and the 1.5 Diesel specifying a fixed 1.9 liters.
  • The 1.2 Turbo 81 kW (HNP) and 96 kW (HNS) variants share an identical capacity range of 1.7-1.8 liters for their manual transaxle, indicating the same gearbox unit is used across both power outputs.
  • A capacity expressed as a range, such as the 1.7-1.8 liters listed for both 1.2 Turbo variants, typically reflects a service fill tolerance rather than a precise overhaul measurement, allowing for minor variation during a drain-and-refill procedure.
  • The 1.5 Diesel (YHZ) manual transaxle capacity of 1.9 liters is a single fixed value, which is more characteristic of a precise fill specification and is notably higher than the range listed for the petrol variants.
  • All three configurations carry a normal use condition, meaning the listed capacities apply to standard operating circumstances rather than severe-duty or first-change-only scenarios.
  • All three entries are classified as transaxle units, meaning the gearbox and final drive share a common fluid reservoir, which accounts for the relatively modest total fluid volumes listed across all variants.
