g'day folks
can any one tell me if i can use an oil that is susposed to be up to both GL4 and GL5 standards in the gear/transfer box of a series 3?
i have read on the net that GL5 will errode the yellow metals inside the boxes. is this true?
the only stuff i can find around here is either GL4 or this other stuff that i have already mentioned.
thanks for all answers
