Don't know if it's available over your way but I've been using -
Castrol-SAF-XA Limited Slip Rear Axle Oil - 80W-140--
in everything, for a while now--Some, most of our high performance cars here have hob cut gears and with normal gearoils they get noisy when they're hot after 150kl or so and with this oil they stay whisper quiet, My thinking is if it's good enough for them it should be top notch in everything, so that's what I do
I believe it was developed for Sauber-Mercedes for the lond distance 24hr races
It's got all the aditives already in it so no need for special lsd medicines
It's not cheap but you don't need much really

Willy,
it doesn't show up on Castrol UK.

I wonder how quiet it would make our whining axles. I saw where someone changed their axle oil every year and they said it made their (IIRC) Spridget axle quiet. I tried this and found that at initial change the axle seemed a lot quieter but after a while the noise was more noticeable, but still quieter than before the first oil change.

For what it's worth, I use:

Axle: https://www.opieoils.co.uk/p-724-castrol-axle-epx-80w-90-mineral-car-gearbox-oil-gl5.aspx

Gearbox: https://www.opieoils.co.uk/p-77362-castrol-manual-ep-80w-90-mineral-car-gearbox-oil-gl4.aspx

Then any left overs of both get mixed together for top ups!
