You're over thinking this a little too much though. While its good to warm things up for long, long term durability (like 200k miles), the fluids that have been put in are designed to work for the Joe Shmo who just gets in his car and drives to work.
It's not a racing engine that requires a specific warm up sequence (which is due partly to the particular fluids used in those vehicles).
Warm it up a little, but beyond that, relax and enjoy it.
Thanks for helping!
