Hi Guys,
All very interesting, especially the diff oil rates you are talking of!
I have just finnished replacing the factory grease in my Genesis LE's center diff with 100 000wt Mugen silicone Diff Oil, (thickest I could get my hands on locally) in an effort to lock the center up more, without running the lock block. I must say that I haven't run it yet, but the center diff is definately looser now than it was originally (even compared to the new unused spare GST one I have). Bit disappointed, but will run it to try it anyway. As I expect it will make it worse than it was. But I need to drive

. I am still going to try to find some 300 000wt, just in case!
Blitzekriec , you said you have found some 500 000wt oil, who makes it? & where can I get some?
