Additional Notes

  • The front differential capacity across all INFINITI FX S51 variants and model year ranges is 0.65 liter. This figure applies uniformly to the FX30d, FX37, and FX50, regardless of fluid type classification (preferred or alternative) or use condition.
  • The rear differential holds a noticeably larger volume than the front. The FX30d and FX50 rear differential capacity is 1.75 liters, while the FX37 rear differential capacity is 1.4 liters across both its 2008-2011 and 2011-2013 year ranges.
  • Under normal and preferred use conditions, the front differential on the FX37 and FX50 (2008-2011) carries a check interval of 15000 km or 12 months. No fluid change interval is specified for those conditions, meaning routine service at those intervals involves inspection only.
  • The FX30d in its 2010-2013 range received a revised check interval for the front differential under preferred and alternative use conditions, moving from 15000 km to 20000 km while retaining the 12-month time limit. The 2009-2010 FX30d retained the shorter 15000 km check interval under the same conditions.
  • The rear differential on the FX30d 2010-2013 also reflects the same interval revision, with the normal-use check interval extending to 20000 km or 12 months, compared to 15000 km or 12 months on the 2009-2010 version.
  • Severe use conditions across all variants and both differentials introduce a mandatory fluid change at 30000 km or 24 months, in addition to the check interval. Under normal or preferred conditions without a severe designation, no change interval appears in the specifications.
  • The severe-use check interval for the front differential on the FX30d 2010-2013 is 15000 km, which is shorter than the 20000 km check interval assigned under preferred and alternative conditions for the same year range. Severe use therefore results in more frequent inspection regardless of the fluid type used.
  • Both preferred and alternative fluid classifications share identical capacity and interval values within each variant and year range. The distinction between preferred and alternative relates to fluid type suitability rather than any difference in service frequency or fill volume.
