Nissan VISCOUS LSD are sealed units so both diffs use the same fluid type.
The highest friction of any differential occurs at the slowest speed and decreases as speed increases........under 10 mph is very high and decent by 55 mph.
Because the fluid is so thick cold and so thin hot........finding a viscosity balance is critical unless you are always in an even warmish climate with little winter.
Measure your summer peak and average diff temp after [during] a 2 hour drive at highway speed.........even a 2% friction loss creates 1 HP of heat ~~ 12,000 BTU [that electric home space heater times 4]

can I pick this stuff up at the auto store?
I ordered mine from here: http://www.synlubes.com/ since there were no dealers close to me.
