Same general concept, yes. I wouldn't say mototune "invented" the concept, it's been done to break race cars in for decades.

Mine is a tad different in that I pre-heat the coolant and use a very lightweight oil for the initial fire. This results in a bit better ring hone as the bores rapidly heat up before doing the actual runs.

 

The reason you want the oil out of there after the first few miles is that during the break in process, you end up with all kinds of metal particulate and other goo in the oil. This is not something you generally want running through your engine for several thousand miles.

In the case of Porsche, et all, they do a flush at the factory after running the engine in, but it never hurts to do one again. Oil is cheap, engines and turbochargers aren't.

 

My dealer uses mobil 1 5w-30 in all Porsches. It is not listed as approved in the owner's manual. What do you guys think?

 

Ideally you want to use the thinnest oil you can get away with to maintain the desired oil flow and pressure the engine needs, within the temperature ranges you'll run it in. I usually use 5w30 for typical street/spirited driving and 10w40 for track use.

Here's a good (and long) overview.

 

Stick to the manual for oil recommendations. We are not running LeMans in our Porsches

You will be hard pressed to find proof that break in procedure A vs. break in procedure B vs. factory break in procedure produces more power or results or prolonged engine life. While it would be a great experiment I would venture a guess you wont see any variance that differs from normal factory tolerances.

Do what makes you feel comfortable. Its like choosing a wax for your paint or color of your exterior - everyones got a preference.
