3 year old Shin-Etsu MicroSI still good?

[PHiZ]

I have had this tube of Shin-Etsu MicroSi since my last system build (3 years?).

Does anyone think it may have gone bad. Looking at it, it doesn't appear to have physically seperated (you know like when peanut butter separates into a layer of oil...)

So what do you think?

Slop some on and see for yourself
