Diff Oils

Iam going to be changing the oils im my front and rear diff, can anybody tell me if i can use FULLY SYNTHETIC oil like Millers TRX Synth 75w90 or just stick to Mineral oil EP 75w80 GL5.
By the way its on a Defender 130 300 Tdi 1996
Many Thanks.
PS Done a search but couldn't find a correct answer .

Yes you can use it if you can afford it.

Is there any advantage over the mineral oil EP? I generally just stick to the recommended lubricants when servicing as it's easier, but if someone on here says differently then they probably know what they're talking about.

If in doubt splash out mate.

On the Landy always believed in regular changes rather than most expensive brand - just my view

Oh! aye, that adds up, I'd aggree with that.

I use half EP and half Lucas Oil Stabilisor which quietens down the diffs no end. Also use it in the engine, gearbox and transfer box. Amazing stuff.

Ha! No Oil Stabilisor in the engine, diffs, gearbox, transfer box etc. it really quietens the old beast down!!!

I run syn trans oils in my 90, but only because i can get it for nowt, if i was paying it would be good old 80/90.
