QX70 3.7 AWD, S51 (2013-2017)	Use: Normal Capacity 9,2 liter Code: RE7R01A 7/1
QX70 5.0, S51 (2013-2014)	Use: Normal Capacity 11,3 liter Code: RE7R01B 7/1
QX70 5.0 AWD, S51 (2013-2014)	Use: Normal Capacity 11,3 liter Code: RE7R01B 7/1

The INFINITI QX70 S51 automatic transmission fluid capacity differs between the two available engine configurations, with the 3.7-liter requiring 9.2 liters and the 5.0-liter requiring 11.3 liters.
The 3.7-liter variants, both AWD and rear-wheel-drive, share an identical 9.2-liter automatic transmission fluid capacity across the full 2013-2017 model year span.
The 5.0-liter variants, both AWD and rear-wheel-drive, carry a notably higher 11.3-liter automatic transmission fluid capacity, reflecting the larger transmission assembly paired with the V8 engine.
The 5.0-liter configuration is specified only for 2013-2014, while the 3.7-liter configuration spans 2013-2017, meaning the two engine variants do not share the same model year coverage.
All four configurations list a normal use condition, meaning the stated capacities apply under standard operating circumstances rather than severe-duty or special-case service scenarios.
The 2.1-liter difference in fluid capacity between the 3.7-liter and 5.0-liter transmissions is consistent across both the AWD and rear-wheel-drive versions of each respective engine, indicating the drivetrain layout does not alter the total fluid fill volume.
