I've heard it's better to drive the car around the block once or twice because it will keep you from getting flat spots. Starting it once a week is fine for the engine, but I think I would drive it around a little too.

With the oil I would just check it and see where it's at when it's been sitting for a while instead of doing a certain amount a week.
I think they can burn that much oil especially at high rpm's even though it was meant to be driven that way.

I'm not an owner but I hope to be one someday...
