RECOMMENDED FLUIDS AND LUBRICANTSPFP:00000
Fluids and Lubricants NLS0007E
*1: For further details, see “Engine Oil Recommendation”.
*2: Using automatic transmission fluid other than genuine NISSAN Matic J ATF will cause deterioration in driveability and auto-
matic transmission durability, and may damage the automatic transmission, which is not covered by the INFINITI new vehicle
limited warranty.
*3: For hot climates, viscosity SAE 90 is suitable for ambient temperatures above 0°C (32°F).
*4: Canada NISSAN Automatic Transmission Fluid or DEXRON
TM VI type ATF may also be used.
