Additional Notes

  • The transfer case fluid capacity is 1 liter across all INFINITI QX70 S51 engine variants, covering the 3.0d V6, 3.7 V6, and 5.0 V8. A 1-liter figure is characteristic of a compact transfer case unit, reflecting a service fill volume rather than a full overhaul or dry fill quantity.
  • The 3.0d V6 carries a check interval of 20,000 km or 12 months under normal use conditions, which is the longest distance-based interval among the engine variants listed for the QX70 S51.
  • The 3.7 V6 and 5.0 V8 variants share a shorter check interval of 15,000 km or 12 months under normal use conditions, placing them on a more frequent distance-based service schedule than the diesel variant.
  • All six configurations share the same 12-month time-based check interval regardless of engine type or model year range, meaning the calendar-based threshold is consistent across the entire QX70 S51 transfer case service schedule.
  • The 3.0d V6 specifications span two consecutive model year ranges, 2013-2015 and 2015-2017, both with identical capacity and interval values, indicating no change to transfer case service requirements across those years for the diesel engine.
  • The 3.7 V6 and 5.0 V8 specifications similarly appear in two consecutive model year ranges each, with the later ranges extending to 2019, and both retain the same 1-liter capacity and 15,000 km check interval throughout.
