Additional Notes
- All three configurations covered in the specifications share the same service fill guidance: the power steering fluid level is maintained between the minimum and maximum marks on the reservoir.
- The INFINITI FX S51 generation spans the 2008-2013 model years for both the FX35 and FX35 AWD configurations, while the FX50 S51 coverage begins in 2009 and runs through 2013.
- The minimum-to-maximum range specification is a service fill indicator rather than a measured capacity value, meaning no discrete fluid volume in quarts or liters is assigned to power steering service for any of the listed configurations.
- All three rows carry a normal use condition, which in the context of these specifications ties directly to the between-min-and-max fill guidance rather than a separate severe-use interval or volume.
- The FX35 and FX35 AWD are listed as distinct configurations under the S51 body designation, yet both share identical power steering fluid level specifications across the full 2008-2013 span.
