That's what I did, ran a few hundred miles then changed it out just to check it and make sure everything was wearing okay.
What posi are you getting? The Eaton posi for the GT that I put in my car said not to use synthetic oil and to use a mineral based oil

They don't do it from the factory like that so I wouldn't worry about it. Install fluid and go.

Royal purple gear oil sucks. Look up the data sheets. Just use motorcraft or moble1 or something to your liking.
