Additional Notes

  • The INFINITI QX80 Z62 transfer case holds 1.5 liters of fluid across all AWD configurations from 2013 onward. A capacity at this level is typical of a service fill, meaning the unit is topped to its operating level rather than fully drained and refilled as in a complete overhaul procedure.
  • For the 2013-2016 AWD configurations under normal use conditions, the service schedule calls for a fluid check every 10,000 miles or 12 months, with no fluid change interval specified. Under severe use conditions for the same years, a fluid change is added at 20,000 miles or 24 months, alongside the same 10,000-mile or 12-month check interval.
  • Severe use conditions generally refer to operation involving frequent towing, off-road driving, extreme temperatures, or repeated short trips. For the 2013-2016 AWD configurations, severe use triggers a mandatory fluid change at 20,000 miles or 24 months, a requirement absent from the normal use schedule.
  • The 2017 AWD configuration appears in two separate row groupings: one covering only the 2017 model year and another spanning 2017-2019. Both share the same normal use check interval of 10,000 miles or 12 months and the same 1.5-liter capacity, but the severe use interval differs. The 2017-only grouping specifies a fluid change at 20,000 miles or 24 months under severe conditions, while the 2017-2019 grouping replaces the change interval with a check at 5,000 miles or 6 months.
  • Starting with the 2019-2021 AWD configuration, the normal use check interval shifts to 7,500 miles or 6 months, a departure from the 10,000-mile or 12-month interval used in earlier model years. The severe use check for the same period is set at 5,000 miles or 6 months, matching the severe interval introduced in the 2017-2019 grouping.
  • The 2021 AWD configuration under normal use carries the longest check interval in the dataset at 15,000 miles or 12 months. Under severe use, a fluid change is specified at 20,000 miles or 24 months, with no separate check interval listed for that condition.
