Just curious, isn't 'Transfer case fluid' & 'Gear oil' the same thing since they are both SAE 75W GL-4 ?
Both of the below fluids have the same numbers for use in our BMW's.
Has anyone ever used the 'Ravenol' yet ?

No. The transfer case oil is a special order item. Only BMW makes it. You can get it at most on-line vendors. Be prepared to pay $45.00.
