TRANS-X limited slip gear oil additive ?

[turbotaone]

Has anyone used this posi additive before? It is sold at Advanced Auto and is called Posi-Trac limited slip gear oil additive. The company that makes it is called TRANS-X(CRC). The bottle says that it meets OEM recommendations for limited slip differentials GM#1052358, Ford#M2C118-A, Chrysler#4318060, and most imports. I'm getting ready to change the rearend fluid in my TTA and was thinking of using this stuff instead of the GM additive. A 7oz. bottle is only $3.99 which is much cheaper than the GM additive. What do you guys think ?

Thanks
James

I used it in my beater 4x4 with no problems. Don't know how it would work in a performance app.

I just run Mobil 1 with no additive. I only put the additive in with conventional gear oil.
