Power steering fluid capacity & service interval

INFINITI QX70, S51 (USA) models utilize power steering fluid with a capacity of 1 liter. Service intervals consist of checks every 10000 miles or 12 months. The data covers 4 configurations.

The configuration chart below lists fill volumes and service intervals for each engine and trim variant.

Additional Notes

  • The INFINITI QX70 S51 power steering system holds 1 liter of fluid across all listed configurations, covering both the 3.7 and 5.0 engine variants in standard and AWD drivetrains.
  • A 1-liter capacity is characteristic of a hydraulic power steering reservoir fill, representing the fluid volume held within the system rather than a full hydraulic pump or rack overhaul quantity.
  • The 3.7-liter configurations, spanning 2013-2017 in both standard and AWD drivetrains, carry a specified check interval of every 10,000 miles or 12 months under normal use conditions.
  • The 5.0-liter configurations, covering 2013-2014 in both standard and AWD drivetrains, share the same 1-liter capacity as the 3.7 but do not carry a listed check interval in the specifications.
  • The 3.7 AWD and 3.7 non-AWD variants are identical in both capacity and check interval, indicating no differentiation in power steering fluid service requirements between the two drivetrain configurations for that engine.
  • The same pattern applies to the 5.0 variants, where AWD and non-AWD configurations share an identical 1-liter capacity with no divergence between the two drivetrains.
  • The 10,000-mile or 12-month check interval on the 3.7 configurations reflects a time-or-distance threshold, meaning whichever limit is reached first would apply under normal operating conditions.
