Picking up my 2014 ML350 BTC tomorrow

I'm in the Toronto (ON) area.
However, this will be my first diesel vehicle (currently have a 535xi) and had a few questions:
1. I've noticed two grades of diesel at local stations - should I be using the 'premium' diesel version? What's the difference between the two?
2. I'm sure this question has been asked a million times before - what's the best way to break-in the engine. Read some posts elsewhere mentioning not to put the car on cruise and some others say to drive hard to break the engine in. I'm confused! Would love to hear your views.
Diesels are great engines and I would break in the way the manual says to do so. I also like to let my diesel engine wake up as easy as possible till it warms up, keeping the RPM low until the oil flows a little better. Driving like you stole the vehical is for people who do not know better.
You will love the torque at low RPM.
Enjoy today, picking up a new Benz is always a good day!

Didn't think that would apply to the low revving diesel and I find myself just driving it easy because it's such a luxo-cruiser.

Sounds like logical advice to me. With the advances in technology and engineering, I think the engines area better equipped/designed for consumers to simply be able to drive normally right off the lot.
Thanks for your feedback though - much appreciated
