Additional Notes

  • The Lexus RC F transfer case fluid capacity is 0.7 liter across all listed model years and both market regions, from 2014 through 2021. A capacity in this range is typical of a compact transfer box unit, as opposed to larger truck-based transfer cases that commonly hold 2 liters or more.
  • All rows specify a transferbox with automatic operation, meaning fluid circulation and engagement are managed without a manual selector, which places greater reliance on fluid condition for maintaining proper lubrication across the unit's internal components.
  • Canadian-market RC F units from 2014-2015 carry a check interval of 16000 km with no time-based component attached. Starting with the 2016-2017 range, the Canadian specification adds a 12-month time limit alongside the 16000 km distance, introducing a dual-condition interval where whichever threshold is reached first would apply.
  • The US-market RC F specifies a check interval of 15000 miles or 18 months across all listed year ranges from 2014 onward. The 18-month time component is notably longer than the 12-month figure used in the Canadian specification, reflecting a market-specific calibration of the service schedule.
  • Converting the Canadian 16000 km interval to miles yields approximately 9940 miles, which is meaningfully shorter than the US-market 15000-mile interval. Despite covering the same vehicle in the same model years, the two markets operate on distinct distance thresholds for transfer case fluid checks.
  • The 2017 model year appears in both the 2016-2017 and 2017-2021 row groupings across both markets. This overlap indicates that 2017 falls within two consecutive specification periods, though the fluid capacity and check interval values remain identical across both groupings in each respective market.
