Penrite 140 Gear oil, it was made for Nissan LSD's.
budget oil with bs advertising. i doubt the "made for nissan", more like it just happens nissan lists it in their recommendations.
i've not seen a mono diff oil on the shelves here and my usual brands don't make one. mineral gear oils are old tech.
i would stick with the semi synthetic (or full synthetic if you can afford it). better oil and wider temp range. less oil changes needed and handles more abuse.
