Kia Opirus / Amanti, GH (EU)

Automatic transmission fluid capacity & service interval

Kia Opirus / Amanti, GH (EU) requires automatic transmission fluid with a capacity of 10,9 liters. Service intervals include checking every 15000 km or 12 months, and changing every 45000 km or 36 months up to 90000 km or 72 months. The data covers 4 configurations.

Additional Notes

  • The Kia Opirus / Amanti automatic transaxle capacity is listed at 10.9 liters across both the 3.5 V6 and 3.8 V6 engine variants, a figure that reflects a full fluid fill rather than a partial service drain-and-refill quantity.
  • A 10.9-liter transaxle capacity is notably large for a front-wheel-drive automatic unit, which is consistent with a multi-speed transmission housing an integrated differential and torque converter fluid volume.
  • The 3.5 V6, covering model years 2003-2008, shares an identical 10.9-liter capacity with the later 3.8 V6 (2006-2010), indicating both engines were paired with the same transaxle assembly or one of equivalent fluid volume.
  • Under normal use conditions, the fluid change interval for both engine variants is set at 90,000 km or 72 months, whichever comes first, placing the service cycle at a relatively extended interval for an automatic transaxle.
  • Under severe use conditions, the change interval is halved to 45,000 km or 36 months for both the 3.5 V6 and 3.8 V6 configurations, reflecting the accelerated fluid degradation associated with more demanding operating environments such as frequent towing, stop-and-go traffic, or extreme temperatures.
  • Regardless of use condition, the fluid check interval remains consistent at 15,000 km or 12 months across all four listed configurations, separating the inspection schedule from the more variable change schedule.
  • The overlap period of 2006-2008 saw both the 3.5 V6 and 3.8 V6 available simultaneously, yet the automatic transaxle fluid specifications remained uniform between the two, with no differentiation in capacity or service intervals during those shared model years.
