LSD is not LS-ing

I had a very tight Ford Motorsport TracLok (or whatever the name Ford uses is!) in my 9" and needed two tubes of friction modifier to even get it to play nice on the street. It was very tight, and sent power to both wheels very readily.
As soon as I had about 15k miles on the diff I changed to my normal 75w/90 Redline Synthetic and noticed that most of my transfer disappeared into nothing! Even with both tires on relatively slippery surfaces, one tire would spin more than the other.
Maybe others have had experiences different from mine, and it's for sure that most of the synthetic lubes are at least "compatible" with limited-slips. But they're perhaps a bit too slippery.
That's about it. Not too much slippery lube and riding the brake (better the parking brake as mentioned) are the only two things I regularly equate with clutch-type LS diffs.
But the fluid part is why I really like the Truetrac. No clutches.

Not much else. But one thing I would add is that I no longer use synthetic gear lubes with clutch-type limited-slips. I don't have much data to support the theory, other than the one time I personally did it.
