I have heard its wise to change diff oil as often as your crankcase if you drive your car hard.

And another excuse to buy all the supporting parts also to do with the diff
I didn't realise yours is an 07, there's a good chance yours is bolted as I recall they switched to welded around that time.

I was told the diff oil didn't need changing but I always change any and all fluids well in advance. I'll probably change the diff oil again at 30k for peace of mind. Already have stocked up on the oil anyway

If you go with Wavetrac the Redline 75w140ns is the only recommended oil. It is essential that you use the Non-slip version otherwise you will void your warranty.
