Additional Notes

  • The Lexus SC 430 (Z40, EU) carries a rear differential fluid capacity of 1.35 liters across all model years from 2001 through 2010, a figure consistent with a service fill rather than a full overhaul volume.
  • The change interval for rear differential fluid is set at 30,000 km or 48 months, whichever comes first, and applies under normal use conditions throughout the entire production span covered by these specifications.
  • For the 2004-2005 and 2005-2010 SC 430 model years, a normal (alternative) fluid option is listed alongside the primary normal specification, both sharing the same 1.35-liter capacity and the same 30,000 km / 48-month change interval.
  • The presence of an alternative fluid designation for the 2004-2005 and 2005-2010 ranges indicates that more than one fluid type was approved for normal use, without any adjustment to the service fill volume or the change schedule.
  • No alternative fluid entry appears for the 2001-2002 or 2003 SC 430 model years, where only a single normal-use specification is recorded at 1.35 liters and 30,000 km / 48 months.
  • The 48-month time limit on the change interval means that even low-mileage vehicles are subject to a fluid replacement cycle based on elapsed time alone, independent of distance traveled.
