Additional Notes

  • The Opel Astra H TwinTop 1.6 16V carries a transaxle fluid capacity of 1.6 liters across all listed model year entries, a figure consistent with the compact semi-automatic transaxle units found in this engine family.
  • The 1.8-liter variant uses a conventional automatic transaxle with a notably higher service fill capacity of 4 liters, reflecting the larger fluid volume required by a fully automatic unit compared to the semi-automatic 1.6 16V transaxle.
  • For the 1.6 16V semi-automatic transaxle covering the 2006-2010 and 2010 model year entries, the specified service action is a fluid check rather than a change, scheduled at 12 months or 30,000 km under normal use conditions.
  • The 1.6 16V entry covering only 2006-2007 carries no interval specification, listing only the 1.6-liter capacity under normal use conditions.
  • The 1.8-liter automatic transaxle entries for both the 2006-2010 and 2010 model year rows specify a fluid change at 60,000 km or 48 months under normal use conditions, representing a longer interval cycle than the check-based schedule applied to the 1.6 16V.
  • The distinction between a fluid check interval on the 1.6 16V semi-automatic and a fluid change interval on the 1.8 automatic reflects a fundamental difference in service philosophy between the two transaxle types present in the Astra H TwinTop lineup.
