Anyone use Lucas Oil Additive?

[D'mon]

I have seen this stuff, and am thinking of adding it into my diffs as I am changing oil this weekend. It seems to work well, but I am concerned as it is the same for manual transmissions, diffs and engine oil (???). I'm doing Slick 50 for Manual Transmissions for my tranny and transfer case, but this will use up my supply (and it seems to be unavailable in my area) and I still want to do the diffs with something.

Once again, I ask opinions....
Thanks.
