Additional Notes

  • The manual transaxle fluid capacity for the Kia Optima TF 2.4 GDI is 1.8 liters across all three listed configurations, covering both the Canadian and U.S. market variants for 2010-2013.
  • A 1.8-liter figure for a manual transaxle represents a service fill volume, meaning the amount of fluid required when refilling a unit already installed in the vehicle, rather than a full overhaul or bench-fill quantity.
  • The Canadian 2.4 GDI specification carries a fluid check interval of 12 months or 15,000 miles, while the U.S. 2.4 GDI specification sets the check interval at 30 months or 37,500 miles, a notably longer period between inspections.
  • Under normal use conditions, the Canadian market specification includes a fluid change interval of 48 months or 60,000 miles, a drain-and-refill schedule absent from the U.S. normal-use row.
  • The U.S. severe-use configuration for the 2.4 GDI introduces a fluid change interval of 75,000 miles, which applies on top of the same 37,500-mile or 30-month check interval shared with the normal-use U.S. row.
  • The presence of a severe-use row exclusively in the U.S. market data reflects a market-specific service structure where operating conditions are formally categorized to determine whether a fluid change is required at all.
