Both of those fall in the Nissan recommendations. I have the manual on PDF as I my G didn't come with one.
From the manual:
Genuine Nissan Manual Transmission Fluid (MTF)
HQ Multi 75W-85 or API GL-4, Viscosity SAE 75W-85 or 75W-90
API GL-5, Viscosity SAE 80W-90*5
*5: For hot climates, viscosity SAE 90 is suitable for ambient temperatures always above 0°C (32°F).
