Ok, I just read the artical. Good article.
I didn't even know that there was a engine oil flush unit out there.
Anyway, I think what pitoman is talking about is the fluid that you put in your engine that thins out the oil and breaks down the varnish.
I might do a double oil change next time using regular dino oil for the first oil change and Mobile1 Synthetic 0W30 for the final oil change. Or, I just might let it go. I guess I'll see when I do my next oil change.
