Those oils you have selected will be fine. I have been running the same brand diff oil AT (Associated Lucas Oil) for nearly six months now with no problems at all.
Be careful not to over tighten the centre diff. If you over tighten the screws you can distort the diff housing and it will constantly leak. Screw the Delrin Spur and diff housing together until flush (not tight), then in a circular rotation, nip up each screw half a turn until firm. Be sure the gasket is clean and free from the original packing grease.
Diff oils irrespective of the manufacture use similar methods for describing the weight or viscosity of the oil i.e. 5000wt/5000cst/5k diff oil. Even though the descriptions are different all three oils should give you similar results.
CST is just an acronym for centistoke which is one of the units of measure for viscosity.
