Hello TP,
As you know, but for the benefit of anyone else who may not be entirely sure, make sure that the car is level when filling the differential so as to ensure that it is not overfilled. You will know when it is full as either you will be able to feel the oil against your little finger if placed appropriately or if too much is added allow the oil to run from the filler hole until such time as the flow stops before refitting the plug.
I have always used an EP 80W-90 oil as I have never seen a straight EP90 oil available to purchase. The multigrade oil has the characteristics of an 80 weight oil at room temperature or below but exhibits the characteristics of a 90 weight oil at operating temperatures. Typically the reference temperature in this case is 100 degrees C. The oils specified within the workshop manual for this purpose are in the main straight EP90 grade oils except for an Esso product long since gone which was a GX90/140 grade and Castrol Hypoy which as far back as 25 years ago was a multigrade 80W-90 oil.
With regards to the de dion tube, it is interesting in that the design allows for the oil filled type to actually contain a reservoir of oil within whereas with the grease type there is only a smear of grease rather than any definable quantity.
