The Frontier has more than one differential, and they don't all take the same fluid. Each axle's exact gear oil spec and capacity is below, plus where to buy it.

Spec anchored to the OEM owner's manual; the capacity, when it carries the verified badge, is cross-checked against an independent source. Never changed by what an affiliate link pays us. Your owner's manual is always the final word — and if your axle has a locker or an option package, double-check the capacity for your exact build.
