Not that anyone really cares but, think about how this would / could impact the environment, positively impact the environment if everyone did 15K instead of 3 or 5K changes.

The only thing that interested me about the new Mobil 1 oil is that they claim that it is 100% synthetic (if I'm not mistaken their regular "synthetic" oil is really only partially synthetic - a la Castrol), and that they claim to have added some new anti wear additives. The idea of a 15000 mile oil change is rediculous for all the sound reasons given above.
The oil change interval thing is kind of interesting. When I was a kid, oil technology was not nearly as advanced as it is now, and the limiting factor on how long oil lasted was not when the additives wore out, but rather when the oil itself broke down. Recommended oil change intervals were typically 3000 miles.
Oil technology improved, though, so oil change intervals started getting longer as oil was made that didn't break down so fast. At one point, Mobil said you could go to a 24000 mile interval using regular Mobil 1 (the only kind of Mobil 1 at the time), and many cars recommended a 15000 mile oil change interval on regular oil.
Then the carmakers started taking advantage of the better oil by building engines that ran hotter and were harder on the oil, because that meant they could run the air/fuel mix leaner and get better gas mileage and better performance out of the same size engine. A side effect, though, was that the oil change interval shrank again.
I suspect Mercedes can get away with 15000 mile intervals because (1) they may not be squeezing quite as much out of their engines, and (2) they probably use a higher quality oil than you get at the average Jiffy lube.
I notice that the Mobil site says that their Extended Performance version doesn't meet some exotic test that their regular Mobil 1 passes. My guess is that it's better to stick with regular Mobil 1 (or another 100% synthetic) unless you're really taking advantage of that longer oil change interval.

Again, there's that nagging thing about manufacturers oil change intervals and how this would impact warranty.

Should I be using synthetic? I brought my car to honda and the guy said to put 5w-30 because it better to put a thiner oil in the winter. But does he know what he's talking about or should I use strictly synthetic?

Your mechanic is right about using a 5W30 for the colder months. It will allow the engine to crank more easily during those cold starts. This is especially true if you are using a non-synthetic. If you use a synthetic, unless it gets extremely cold, a 10W30 will do as synthetics still pour and flow well in the cold. I've been known to use a 5W30 Mobil 1 synthetic when I was parking outside for many hours at temps colder than -25*C. The coldest being -38*C and I was sure glad I had 5W30 synthetic and a block heater.
