Generic break in recommendations are very similar across most makes and models:
First 1000 miles:
Avoid full throttle.
Avoid steady sustained speeds.
Brake gently.
Don't race a cold engine.

My 04 is at approx. 2500 miles, hasn't used a single drop of oil (yay!!) and the oil is the color of Sue Bee honey (like new!).

Toyota has SERIOUS engine damage liability over oil gelling, which they at first denied. They 5K interval is far from a "gimmick", there were V6's that had oil turn to a solid.
I'm going to Mobil 1, like in all my cars, at 5k.
The Miller cycle intake timing has NOTHING to do with oil life.
