This is assuming you have a Nissan R200V. If you have another VLSD, consult the manufacturer of that diff for fluid recommendation.


According to the FSM, Nissan recommends API GL-5. Same as the R200 open diff.

Nissan recommends several range of viscosity: 75W, 80W, 75W-90, 80W-90, 85W, 90, 140 based on your climate.

80W-90 is recommended if the temp is below 104* F.


As for brand, use any brand you like as long as it's a GL-5 fluid. No more no less.
