Which oil for Diff please?

[bhpjon]

Hello again chaps, i am looking for guidance on which diff oil i should use in its annual service could anyone give me any pointers please?

There are a lot of choices here,as with the other oils also.I use Redline super heavy shockproof.I get it from Demon Tweeks,not cheap but very good

Don't make a mistake here. The oil viscosity is critical with LSD diffs. Get it wrong and you'll pay dearly. I don't know the answer but it's in the bible.

You don't say how old your car is to give an indication of what diff it has.
GKN (old) BTR (newer).
The GKN diff uses hypoid 80W/90 limited slip if it is an LSD. The BTR uses 80W/140 LSD oil.

It is a 95 5.0litre chim which i think has the btr diff (the one with lots of fins??)
