INFINITI QX70, S51 (EU)

Power steering fluid capacity & service interval

INFINITI QX70, S51 (EU) models utilize power steering fluid with a capacity defined between min and max levels. Service intervals include checks at 20000 km/12 months or 15000 km/12 months. The data covers 6 configurations.

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

Additional Notes

  • All INFINITI QX70 S51 power steering fluid specifications express capacity as a reservoir level range rather than a fixed volume, meaning the fluid level is maintained between the minimum and maximum marks on the reservoir rather than filled to a precise measured quantity.
  • The 3.0d V6 engine variants carry a check interval of 20,000 km or 12 months under normal use conditions, which is the longest distance-based interval among the QX70 S51 power steering specifications.
  • The 3.7 V6 and 5.0 V8 engine variants share a check interval of 15,000 km or 12 months under normal use conditions, placing them on a more frequent distance-based schedule than the 3.0d V6.
  • All six configurations share the same 12-month time-based check interval regardless of engine type, meaning the calendar-based service frequency is uniform across the entire QX70 S51 power steering specification range.
  • The 3.0d V6 spans two consecutive specification periods, 2013-2015 and 2015-2017, both carrying identical check intervals, indicating no change in power steering service requirements across those model year boundaries.
  • The 3.7 V6 also appears across two periods, 2013-2015 and 2015-2019, with consistent 15,000 km or 12-month check intervals in both, reflecting no revision to the service schedule between the earlier and later production spans.
  • The 5.0 V8 similarly spans 2013-2015 and 2015-2019 with unchanged check intervals across both periods, aligning with the 3.7 V6 on both the distance and time-based service frequency.
