I believe that's made by Shell. S-tec sounds familiar. That's what I put in our transfer cases. Part #OIL0005 (BMW# 83222409710). Not cheap. But much cheaper than a transfer case.

Never had an experience exceeding the 1% tolerance through wear on an X drive vehicle. And we've had 5 of them now. As Andrew said, pictures and measurements would be helpful.
