Gents,

I have an E46 M3, BMW have advised that it would be a good idea to upgrade the oil in the rear diff due to a "graunching" (their words, not mine) sound when turning tight corners (in carparks for instance)

Predictably, BMW have also advised that I need to part with at least a Kidney in order to pay for said diff oil change.

If, hypothetically, I was a tight bd with a lot of free time, what would be the best oil to put in my Diff?

Please note, I have no idea what oil is in there at present, I assume it's the original stuff, I can't find any paperwork stating that the previous owner (I know, I'm a peasant) had changed it at all.

Thanks for your time and help.
