Additional Notes

  • The transfer case fluid capacity across all listed Cadillac CT6 (EU) configurations is 0.8 liter, a figure consistent with the compact transfer units typically found in luxury AWD sedans of this class.
  • The 0.8 liter figure applies to both the 2016-2017 and 2017-2019 CT6 3.0 AWD Twin Turbo variants, indicating no change in transfer case fluid volume between the two production spans.
  • Under severe use conditions, the CT6 3.0 AWD Twin Turbo carries a transfer case fluid change interval of 72,000 km for both the 2016-2017 and 2017-2019 model ranges.
  • Severe use conditions, when tied to the 72,000 km interval specified here, represent a more demanding service schedule than normal use, reflecting the additional stress placed on transfer case fluid under harder operating circumstances such as frequent towing, off-road driving, or extreme temperatures.
  • No fluid change interval is listed under normal use conditions for either the 2016-2017 or 2017-2019 CT6 3.0 AWD Twin Turbo, while the severe use rows carry the explicit 72,000 km change figure.
