Hi,

The Castrol is good, many of the E30 M3 guys running
LSD with 30/30 ramp angles and 75% lock
up use it.

I have run the Millers 75-140 fully syn in
my E30 M3 DTM Diff, but its very thick
that you can not use the diff pump when oil is cold.

The Motul 75-140 comp is very good but very
expensive.

Some swear by Royal Purple, both in their
Diffs/Boxes and Engines.

What put 'Oil' into perspective for me a while back
was that when talking to Tractive about what
oil we should use in their 6 speed Sequential G/box
they said '' Use Coma, and change it a little
bit more frequent''.

Regards,

The Gorilla.

It only holds about 1.5 ltrs so cant be that expensive!!! I can supply it if you require.
Cheers
Will
