If it meets GM4718M standards you are fine.... It should be somewhere on the oil container. 
Here you go:
Mobil 0W-30
In other words, it's fine...

@ Jim TN, no I use 93 octane.Do you live and die by your owners manual?
@Freyke, thanks for the info its much appreciated.
@ CClive, just reading the container its saying improved gas milage(every little bit helps)

What Kind of Engine Oil to Use
Look for two things:
• GM4718M
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.
You should look for and use only an oil that meets
GM Standard GM4718M.
Notice: If you use oils that do not have the
GM4718M Standard designation, you can cause
engine damage not covered by your warranty.
• SAE 5W-30
As shown in the viscosity chart, SAE 5W-30 is best
for your vehicle.
These numbers on an oil container show its
viscosity, or thickness. Do not use other viscosity
oils such as SAE 20W-50.

The 0W-30 is great for Northern climes... Esp. for non-garage kept vehicle's that must "soak" in the cold during long Northern nights... I don't see any harm in it though.
"Do not use other viscosity oils such as SAE 20W-50"
The thing to be concerned about here is the 50 summer weight, it may be too viscus to flow thought the engines oiling journals, etc.. In the end starving the engine of oil... I've used 50 before in other cars when I lived in AZ...

My opinion backed up with lots of reading:
Mobil 1 0W30 and 5W30 and 10W30 will all have about the same viscosity at normal operating temps. All three will have more viscosity cold than they will at normal operating temps. So where is the problem?
I don't see any and so use the 0W30 stuff in my Corvette. The viscosity cold is closer to that when warm than in the other two choices. This should result in some efficiency gain with no risk of loss somewhere else.

I use regular mineral oil of the correct API rating along with 89 octane gas.
Here is the pic on the DIC av. mpg for the 700 mile round trip to Funfest this year. Hard to read but it is 34.5 mpg on an 08 436hp M6 with the cruise set at 60 and all interstate miles.

Why out guess the people who designed the engine?

No, because that's not what GM and my owner's manual calls for.
Do you burn regular gas in yours?

Anyway, there are always good answers to the "can I use this oil" question, and they are easy to find. Here is a good answer from another thread:
...and most 0-30 is thicker than 5-30 when both cold and hot. I wish they did away with the X-XX crap on the bottle. Too many people think it means something important. This is why a corvette forum is not an oil forum. You might as well ask the guy at Wal-Mart what he thinks. Go to BITOG. It sure helped me with my oil issues in my LS1. FOllowed their recommendation and cut my oil usage from about 1qt every 2-2500 miles to 1qt ever 4500-5500, depending on how I drove it.
The BITOG he refered to is http://www.bobistheoilguy.com
That's where you go to really learn what oil you should use. They base the oil they run off of oil analysis done at their own expense, and use what works.

I'm thinking a O weight oil would alow a faster harm up in sub zero temps. thus helping to get the computer into closed loop faster. May decrease fuel consumtion during this operation. But when harm all things would be equal.................

Buy your favorite oil.
Get an oil analysis done at about 3500 miles.
Decide.
