Kevin,
You have just discovered one of the miracles of Rotella oils, which is the very strong detergent and particle suspension packages that good diesel oils require. Rotella is intended to actively remove, trap and suspend trash in your engine and IT HAS STARTED DOING IT IN YOUR ENGINE right now.
Within the first 10 miles it has found, stripped and suspended some of the crap your previous oils had left coating the inside flat surfaces of your engine. Give it a few thousand miles and it will finish the job.
You will find threads here on the list where we tell folks that Rotella can strip old sludge and varnish deposits from the inside your engine and the first oil change seems to come quickly (but really isn't necessary as Rotella will hold the shite in suspension for like 50,000 miles if you could tolerate leaving your oil in there that long).
An example I gave was my late XV535 which had been oil abused by a female previous owner -- it had sludge so thick that the rocker arm motion went through a channel of congealed crap in when you took off the rocker covers. My first oil change came real fast on that one when I first put the Rotella in it to clean it up. Within the first year, all the sludge was gone and the parts were clean and shiny when you took the covers off to adjust the valves. Rotella stripped and suspended all of it and all that crap poured out into the drain pan with the dirty oil.
Magical stuff, that Rotella.
And yes, you are normal -- nobody can tolerate holding off on that first oil change for the full recommended mileage. They (like I did) go ahead and change it after a 1,000 miles or so jest to get the gawdawful ugly out of there.
The next oil change will likely still get ugly relatively fast, but at the third and later all the crap should be gone and the oil will stay cleaner a lot longer.
