MINI specifies their Hypoid Axle Oil G3 for the rear differential on the F60 Countryman ALL4.

The rear differential oil is not a 'regular' maintenance item and would 'typically' not require replacement on a 1 year old vehicle.

I don't know about your particular car, but differentials in general do require periodic oil changes. They contain gears and bearings, which do wear. The oil is replaced to keep the worn off bits from accelerating the wear. The service interval is usually longer than for other things, such as transmissions.

I just purchased a 2020 Countryman and it was not well maintained, actually nothing was done to it for the past year so I went to change the fluids and looked up my vehicle to put in my favorite brand and the differential fluid came up which I never noticed before in other vehicles:


it also says "U/K TRC 1.1 pints Fill to level of fill plug." which I am guessing that is the amount, but not familiar with the plug level fill or even if I have to deal with this to keep a vehicle properly maintained? Anyone change the differential and when/for what reason would you upgrade the fluid for the rear axle?
