Hyundai XG (EU)

Automatic transmission fluid capacity & service interval

Hyundai XG (EU) automatic transmission fluid capacity ranges from 7,8 to 8,5 liters. Service intervals require checks every 15000 km or 12 months. The data covers 3 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The Hyundai XG (EU) automatic transaxle fluid capacity varies by engine displacement, with the 2.5i V6 and 3.0i V6 sharing a 7.8-liter fill and the 3.5i V6 requiring a notably larger 8.5-liter fill.
  • A 7.8-liter automatic transaxle capacity, as specified for the 2.5i and 3.0i V6 variants, is consistent with a full service fill that accounts for fluid retained within the torque converter and valve body, not just the pan.
  • The 3.5i V6 transaxle capacity of 8.5 liters represents a 0.7-liter increase over the smaller-displacement variants, a difference that reflects the larger transaxle assembly paired with the higher-displacement engine.
  • All three engine variants across the 1999-2005 model range share an identical fluid check interval of 15,000 km or 12 months under normal use conditions.
  • The 15,000 km or 12-month check interval applies specifically to normal use conditions, meaning the interval is tied to standard operating environments rather than demanding or high-stress driving cycles.
  • All three configurations are noted as transaxle, automatic, indicating a transversely mounted transmission integrated with the final drive, which is the standard layout for front-wheel-drive vehicles and directly informs the total fluid capacity figures.
