Also, is it advantageous to run a little more oil than recommended in these engines?

We don't know what kind of vehicle you have. Unless you have a 4valve 4.6 the answer is most likely no.
And you can bring your own Mobil1 to the dealer and have them put it in. They most likely won't have a problem with that. Just make sure the tech actually uses your oil and doesn't set it aside.
