I know nothing about Rotella so maybe you have a working idea. Many years ago when I got my first V8 Packard, was dumb and ignorant & followed some very bad advice to use high detergent oil and a pint of kerosene to get the crud out. No dropping the pan first or hardly anything else done that many have recommended on the forum as preliminaries.

The detergent concoction did as advertised and loosened all the crud so well that it clogged the oil intake screen. After about a 5 mile trip, the engine started knocking severely. In my case, not the end of the world because I had planned to do the engine anyway--just not that soon.
