Additional Notes

  • The Kia K900 3.3 T-GDI rear differential holds between 1.35 and 1.45 liters of fluid, a capacity range that accounts for normal fill variation during a service procedure rather than representing two distinct fill levels.
  • The front differential on the AWD variant carries a noticeably smaller fluid volume, with a capacity of 0.65 to 0.75 liters, roughly half the rear differential's capacity across the same 2019-2020 model years.
  • Under normal use conditions, both the rear differential on the non-AWD configuration and all differentials on the AWD configuration share an identical check interval of 36,000 miles or 72 months, with no fluid change interval specified for normal use.
  • Under severe use conditions, a fluid change interval of 72,000 miles is added on top of the 36,000-mile or 72-month check interval, applying equally to both the front and rear differentials on the AWD variant and to the rear differential on the non-AWD variant.
  • The rear differential capacity of 1.35 to 1.45 liters is identical between the standard rear-wheel-drive 3.3 T-GDI and the AWD variant, indicating the same rear differential unit is used across both drivetrain configurations for the 2019-2020 K900.
