Diff oil

[CTE]

I have an LSD in my TVR from a Ford Sierra 4x4i. When I fitted the diff, in my ignorance, I used EP90 gear oil. I seem to remember reading somewhere that you have to use a specific grade of oil for the viscous coupling, which makes perfect sence. Can anyone tell me what the oil spec is...guess I could ask the local Ford dealer, but then they could not tell me what the correct tracking settings were on my RS focus the other week?

I've had good info before by phoning Ford technical. I think this is the number.... not sure.

a big oil co like shell or a smaller firm like millers oil would have a chart of recomended grades
