Not true. More oil does NOT mean more pressure. The reason you can run too much oil is because you may bathe the crank eventually. This does not happen at 6.5 qts. in the Duratec.

And engines do not get "used" to anything, especially not the amount of oil.

There are several major decisions outlined in the FAQ.
What oil to choose, how often to change it, what filter, and how much to run.
The first three depend on a lot of factors, and can vary from person to person.
The fourth is 6 or 6.5 qts. Not 5.5, not 5.8, certainly not 5. If you corner your car hard (or anyone else does), run 6.5. Otherwise 6 is fine.
