Additional Notes

  • The Hyundai Sonata NF (EU) automatic transaxle fluid capacities range from 7.1 liters on the 2.0-liter petrol engine up to 8.6 liters on the 3.3i V6, reflecting the differing internal volumes of the transmission units fitted to each engine variant.
  • The 2.0-liter petrol variant's 7.1-liter capacity figure applies under severe use conditions, paired with a 90,000 km change interval specific to that service classification.
  • The 2.0 CRDi diesel variant carries an 8.5-liter transaxle fluid capacity under normal use conditions, which is notably higher than the 7.1-liter figure listed for the 2.0-liter petrol engine despite both sharing the same body generation.
  • The 3.3i V6 holds the largest automatic transaxle fluid capacity in the lineup at 8.6 liters, which is consistent with the greater mechanical demands and physical size associated with a six-cylinder drivetrain configuration.
  • Both the 2.4i 16V and the 3.3i V6 share identical service intervals under normal use conditions: a fluid level check every 15,000 km or 12 months, and a full fluid change every 90,000 km or 72 months, whichever comes first.
  • The 72-month time-based change interval on the 2.4i 16V and 3.3i V6 means that even low-mileage vehicles would reach a fluid change point after six years of operation regardless of distance traveled.
  • The 2.4i 16V transaxle capacity of 7.8 liters sits between the 7.1-liter petrol 2.0 and the 8.5-liter diesel 2.0 CRDi figures, placing the four-cylinder petrol variants in a distinct capacity tier from the diesel and V6 configurations.
