Oil Weight
I took my car into the dealer and had the oil changed. I later found out they used Mobil-1 10W30 in lieu of the 5W30. SHould I take it back and get it replaced? Or is it no big deal now that summer is here.

For a SoCal summer, they may be some nearly unmeasurable advantage to 10W-30.

My Owner's Manual says that the ONLY approved grade of oil is 5W-30. Technically, that means GM could deny a warranty claim if you had engine problems, although that seems pretty unlikely.
Since the dealership's techs are bozos, I'd either:
Avoid them like the plague, or
Go back and make them give me a free oil change because they put in the wrong stuff.
Of course there's always the possibility that they used the correct oil but the paperwork is wrong, my dealer once showed that my c5 got a Subaru oil change. But they used the right oil, and we all had a good laugh.

I wasn't even going in for an oil change but to turn my roof in. The oil change was a "well I'm already here may as well get that done". I was pissed. They did not even have 5W30 available so I was stuck big time.
Fortunately the paperwork just says oil change. Nothing about weight.

As an aside, many people that worry these sorts of differences between motor oils think M1 10W-30 is superior to 5W-30, though most of these nit-pickers also say 0W-40 is superior to both.
GM is never going to deny you warranty coverage over something a Chevy dealer did, but if you are the type that cares about what GM says, the owners manual specifically says not to use different oil weights than 5W-30. I'd find a different dealer... these guys are obviously not detail-oriented. A bad trait in a service department.

B) the difference between these to oils is so small that only at negative temperatures will anything show up
C) M1 specs for these two oils are so close that it is possible that Mobil runs large batches of the product. Batches that come out a little thick go into 10W-30 cans, batches that run a little thin go into 5W-30 cans, and batches that hit the numbers can go in EITHER can!

I've always used 10w-30 mobil 1 in every LStype motors I've had (3).
Never had a problem. Live in SO CAL. Even in Utah sking at 10000 feet in temps at 0 degrees it starts and I have oil pressure right away. And if you ever had an oil related problem, which I dought. I defy those service techs to be able to tell if it was 5w-30 or 10w-30.BTW 10w-30 doesn't void anything.
