Additional Notes

  • The rear differential fluid capacity across all Kia K900 configurations listed — covering both the 3.8 V6 and 5.0 V8 engines, and spanning 2014-2018 — is uniformly 1.4 liters. A capacity in this range is typical of a rear differential service fill, representing the working fluid volume held within the differential housing under normal operating conditions.
  • Under normal use conditions, the 3.8 V6 and 5.0 V8 configurations share an identical service schedule: a fluid check at 40,000 miles or 48 months, whichever comes first. No fluid change interval is specified for normal use, meaning inspection alone satisfies the maintenance requirement under those conditions.
  • Under severe use conditions, the same 40,000-mile or 48-month check interval applies, but an additional fluid change at 80,000 miles is also required. Severe use typically encompasses operating conditions such as frequent towing, trailer hauling, repeated short trips, or driving in extreme temperatures — all of which accelerate fluid degradation in a rear differential.
  • The 80,000-mile change interval under severe conditions applies equally to the 3.8 V6 and 5.0 V8 variants across all listed model years and market designations, with no variation between engine types in the drain-and-refill schedule.
  • The 3.8 V6 engine appears across three distinct configuration entries: an initial 2014-2015 entry without a market designation, a CAN-specific entry covering 2015-2017, a CAN-specific entry covering 2017-2018, and a USA-specific entry covering 2015-2018. Despite the separate regional and year-range designations, the rear differential fluid capacity and service intervals remain identical across all of them.
  • The 5.0 V8 engine is listed under two separate year-range entries: 2014-2015 and 2015-2018. Both share the same 1.4-liter capacity, the same 40,000-mile or 48-month check interval, and the same 80,000-mile change interval under severe conditions, with no specification differences between the two periods.
