Additional Notes

  • The rear differential on the INFINITI QX50 J55 2.0 AWD holds 0.55 liter of fluid, a figure consistent with a compact rear differential unit rather than a larger axle assembly requiring a full service fill volume.
  • Under normal use conditions, the rear differential fluid change interval is set at 20,000 miles or 24 months, whichever comes first.
  • A separate check interval of 7,500 miles or 12 months is specified alongside the change interval, meaning the fluid level and condition are inspected well before a full drain and refill is due.
  • The 2018-2022 and 2022-onward AWD configurations share identical rear differential capacity and service interval figures, with 0.55 liter capacity, a 7,500-mile or 12-month check, and a 20,000-mile or 24-month change interval applying across both entries.
