The LSD is called a trac-lok. I think it'll say something like that on your axle tag. I believe it's the tag with the gear ratio on it.
The additive is due to the fact that it is a clutch based limited slip as opposed to a gear based. It needs the additive in order to function properly.
You can find gear oils with the additive already in it. Find an oil that's designed for them and you won't have a problem. Cheaper oils are what you stay away from.
