I remembered incorrectly...
I found the following quote in my book: ..."warm oil drains more easily, and the contaminants will be suspended in it..."
So velocity shouldn't matter as long as you change the oil while warm.
Oh well, I just got a good forearm workout and the oil change was really quick!
