Additional Notes

  • The 1.6 T-GDI engine in the Kia Soul SK3 pairs with a semi-automatic transaxle rather than a conventional fully automatic unit, which accounts for the relatively modest fluid capacity of 1.9 to 2 liters across both use conditions.
  • A capacity in the 1.9 to 2 liter range is consistent with a service fill specification, reflecting the volume needed during a routine fluid top-up or partial drain rather than a complete overhaul refill.
  • Under normal use conditions, the specification calls for a fluid check at 37,500 miles or 30 months, with no change interval listed for that condition.
  • Under severe use conditions, the same 37,500-mile or 30-month check interval applies, and a fluid change is additionally specified at 75,000 miles.
  • The 75,000-mile change interval under severe conditions represents double the check interval, meaning a fluid inspection is due at the midpoint before a full change is required.
  • The capacity figure of 1.9 to 2 liters is identical across both the normal and severe use rows, indicating that use condition affects service timing but not the volume of fluid involved in a service event.
