I plan to use it on my JB23 Jimny. Is there any problem using it with open differentials and transfers?

Open differentials and transfers for JB23 Jimny can be used under certain conditions.
Open differentials must not have a friction transmission mechanism such as LSD (mechanical differentials are acceptable).
For transfers, they can be used if they are manual, but not if they are automatic.
The recommended amount of oil to be added is 10-20% of the amount of oil, which is slightly more than the engine oil.
