on the M96 engine, from porsche, the group IV oil was a requirement due to the way the valves and lifters were designed, iirc.

If am not mistaken, todays engines are built with much tighter tolerances hence the longer oil drain cycle, better fuel economy and engine longivity. Technology is a wonder full thing. Ergo the new cars call syn oils.

The thing with synthetic during break-in is that it (supposedly) gives such high lubricity that you don't get the wear that you need for break-in. (Break-in is basically the parts wearing in to each other so they fit perfectly, which is not possible from the factory)
Or maybe on the high end cars like the vette and 911 they pre-break in the engine at the factory?
Super-tight tolerances and latest cylinder honing techniques do reduce the need for break in but I don't think it is completely eliminated.

Your vehicle’s engine requires a special oil meeting
GM Standard GM4718M. Oils meeting this
standard may be identified as synthetic. However,
not all synthetic oils will meet this GM standard.
Look for and use only an oil that meets GM
Standard GM4718M.

Here is a link to the Mobil 1 site. The link will run through the 40+ cars that come from the factory filled with Mobil 1.

Because Mobil1 uses it as advertising. Mobil wants to be associated with the "cream of the crop" of those manufacturers. I never put much merit on Mobil's factory fill claims as a means to qualify their oil.

Since I follow the factory specs on time/miles, I see no sense in using an oil that is priced and claims to be good for high/longer change intervals.

But that's just the thing. The "required miles" is what the book says. The book says go by message center, and it can be as much as 10,000 miles, or if message center is disabled or prematurely reset, 5,000 miles from last oil change.

That is an EXCELLENT idea. No one, to my knowledge, has done a true scientific experiment to determine if the Message Center's oil check percentage and messages are consistent with the quality of the oil. Bravo, man. Please post this in as much detail as possible. This would be landmark and possibly change the basic foundation of how most people change their oil, which is through fixed intervals.
What I want to know is how smart the OLM is. This is the first car I have ever owned with that feature. It would be interesting to see if it calculates oil life based on RPM, vehicle speed, fueling demands, temperature, etc. The only thing I can do for now is to have the oil analyzed and see how far it can go in relation to the OLM.

Good comments by everyone. I will leave the oil in until I have at least 3000 miles then I will change it to something else. The way the wife drives I will probably have at least 4 months to get educated on all the new oils and synthetics on the market.

It will be just a standard oil analysis that measures TBN and wear metals. I don't know if you have ever had one done before, but the lab recommends an oil change interval based on how the engine wears, TBN, and a few other measurable parameters such as actual viscosity.
