Probably.
But Good old (low cost) 80W90 gear oil (mineral or semi synth) is fine for the transfer box and diffs and any semi/fully synth, MVMTF 75W80 will do for your gearbox.
Unless, of course, you are planning a desert rally or a 48hr leMans style event, maybe a dash to and several laps of the Nürburgring ?
