Additional Notes

  • Across all INFINITI FX S51 (EU) variants, the power steering fluid capacity specification is expressed as a level range rather than a fixed volume, meaning the reservoir must be filled to fall between the minimum and maximum marks on the reservoir rather than to a precise measured quantity.
  • The FX30d S51 produced in 2009-2010 carries a check interval of 15,000 km or 12 months under normal use conditions, whichever comes first.
  • The FX30d S51 covering the 2010-2013 period has a longer check interval of 20,000 km or 12 months under normal use conditions, making the distance threshold notably higher than the earlier FX30d specification while the time limit remains the same.
  • The 20,000 km distance interval on the later FX30d S51 is the longest among all variants listed, distinguishing the diesel-engined model in the later production window from the petrol-engined FX37 and FX50 counterparts.
  • The FX37 S51 carries a 15,000 km or 12-month check interval under normal use conditions across both the 2008-2011 and 2011-2013 production periods, with no change in the service interval between the two date ranges.
  • The FX50 S51 also specifies a 15,000 km or 12-month check interval under normal use conditions for both the 2008-2011 and 2011-2013 periods, consistent with the FX37 across all listed years.
  • All six rows carry a normal use condition designation, meaning none of the listed specifications account for a separate severe-use interval for power steering fluid on the FX S51 range.
