INFINITI QX70, S51 (USA)

Brake fluid capacity & service interval

INFINITI QX70, S51 (USA) models require brake fluid. Service intervals include checks at 10000 miles or 12 months, and changes at 10000 to 20000 miles or 12 to 24 months. The data covers 8 configurations.

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

Additional Notes

  • The INFINITI QX70 S51 brake fluid capacity is expressed as a fill range between the reservoir's minimum and maximum marks rather than a fixed volume, which is standard practice for hydraulic brake systems where the fluid level reflects pad wear rather than a measurable service quantity.
  • Under normal use conditions, the 3.7 AWD and 3.7 (RWD) configurations share identical brake fluid service intervals: a check at 10,000 miles or 12 months, followed by a change at 20,000 miles or 24 months, whichever comes first.
  • The 3.7 AWD and 3.7 configurations specify a fluid check interval at 10,000 miles or 12 months under normal use, a step not present in the 5.0 AWD and 5.0 specifications, where the normal-use schedule moves directly to a change interval.
  • Under severe use conditions, all four configurations — 3.7 AWD, 3.7, 5.0 AWD, and 5.0 — converge on the same change interval of 10,000 miles or 12 months, cutting the normal-use change interval in half.
  • The 5.0 AWD and 5.0 configurations cover model years 2013-2014, while the 3.7 AWD and 3.7 configurations span 2013-2017, meaning the longer production run applies exclusively to the 3.7 engine variants within the S51 generation.
  • For the 5.0 AWD and 5.0 configurations under normal use, the change interval is set at 20,000 miles or 24 months, aligning with the 3.7 variants on the same change threshold despite the absence of an intermediate check step in the 5.0 schedule.
