I think my diff (English axle Titan carbon plate diff) is starting to make a bit of noise. Its probably a bearing. I checked the oil level and it was OK but the oil was very black.
Im thinking of changing it.
What are others using GL4 or GL5
I have an idea myself but would like to know what others use?
How black is diff oil supposed to be?

Fairly sure diff oil isn't meant to be black at all...

Generally diff (+gearbox) oil doesn't go black. Normally stays very clear with possibly a slight metalic sheen when drained, however I don't have enough experience with LSD's to know whether that makes a difference. I guess it's possible that the carbo plates might cause it.

Spoken to Titan i should be using Motul 75-W140 competition oil.
Also spoke to a well regarded builder of diffs who said go with Titans recommendation. Although previously they hinted that the oil i had in was too thin.
Balls, I hope I've not done any damage. I suppose plate diffs can always be rebuilt...
Out with the sucky thing (insert girlfriend joke here) this weekend to get the old oil out.

Did Titan have any comment on the colour?

Re: How black is diff oil supposed to be?
I was recently astonished to discover that the diff oil in my 2010 BMW (50,000miles, open) was grey/black with a mild sheen! BMW claims that the diff oil doesn't need to be changed - it's is filled for life - I don't agree.
The LSD oil in my Toyota 4x4 was still golden brown at a similar mileage.
It's not just the LSD plates that cause the blackness. Good luck.
