Additional Notes

  • The Lexus IS 250 (2005-2010) carries a dry fill capacity of 7.2 liters, which represents the total fluid volume required when filling a fully drained or rebuilt transmission from empty. The service fill for the same unit is 1.5 liters, reflecting only the partial volume displaced during a routine fluid exchange without a complete drain.
  • From the 2010-2011 model year onward, the IS 250 dry fill capacity increased to 7.5 liters and the service fill rose to 1.8 liters, values that remain consistent through the 2011-2013 range. The 0.3-liter increase in service fill relative to the earlier variant suggests a difference in the transmission unit used across those production periods.
  • The IS F carries a dry fill capacity of 10.5 liters across all listed model year ranges from 2008-2013, substantially higher than the IS 250 figures. A service fill of 3.7 liters accompanies all IS F entries, a volume consistent with the larger transmission assembly paired to the high-output V8 engine in that variant.
  • Under normal use conditions, the IS 250 (2005-2010) specifies a fluid check interval of 48 months or 60,000 km with no change interval listed, indicating the fluid is treated as a lifetime fill under those conditions. The severe use schedule for the same period adds a fluid change at 90,000 km or 72 months, alongside an earlier check at 45,000 km or 36 months.
  • The IS 250 (2010-2011) and (2011-2013) entries carry identical interval structures to the 2005-2010 severe use schedule, with checks at 45,000 km or 36 months and changes at 90,000 km or 72 months under severe conditions. Under normal use, the check interval remains at 48 months or 60,000 km with no change requirement listed.
  • The IS F check interval under normal use is listed solely as 36 months across all model year ranges from 2008-2013, with no distance-based figure accompanying the time interval. Under severe use, a fluid change at 72 months is added to the same 36-month check interval, doubling the time threshold before a change is required.
  • The IS F severe use schedule specifies only time-based intervals, with no kilometer figures present for either the check or change intervals. In contrast, the IS 250 severe use schedule combines both time and distance thresholds, applying whichever is reached first as the service trigger.
