I bought a used 2011 Camaro that is supposed to get 5w30 oil.
The shop ticket from the dealer listed an oil change with 0w20.
I know if I ask they’ll say it’s just a typo, they always do the
right thing. Should I do a proactive change to 5w30 just to be
safe?
Next oil change…put it back to 5W-30. Don’t worry about it and drive.
I’d change it more because I don’t believe anything dealer tells me more than the wrong viscosity.
Of course we JUST changed the oil… It was driven by a little old lady only on Sundays… That smell is NOT the corpse found inside in the closed garage…
I would just continue to drive, but I would check the oil frequently. I had a shop.put 5W-20.in a vehicle that required 10W-30. It was in the winter. I just checked the oil frequently but never had to add a quart until the next oil change.
Drive it and see if the Check Engine light comes on for VVT codes.
Then change the oil to what the manufacturer recommends.

While it probably will not be a problem to wait for the next change, if it’s worrying you have them change it to the correct oil. It was their mistake, and it’s in writing that they made the mistake.

ask them to change it to the proper spec
treat the current oil as a “flusher fluid” 
Yeah, the dealer is far enough away that it would be a pain in the butt to get them to do the oil change.
I’d let it ride and keep an eye on the level, unless you do a lot of high speed cruising in hot weather.
The dealership probably used 0W20 because that’s what new vehicles take and they don’t feel like keeping other oil in stock. Keep an eye on it for now and avoid the dealership in the future because if I’m right their shop cuts corners.

If it was me, I would just change it ass soon as I found oit it was the wrong oil. Oil is cheap.
My son has a 2013 Camaro and 5/30 is recommended for that. With summer here I think I would want the 5/30 but I also don’t think the 0/20 will hurt anything. I might be tempted to have a very short oil regimen coming up and go back to 5/30.
Wife’s 07 Lexus ES350 oil recommendation WAS 5W-30 dino. My 14 Highlander with the same engine oil recommendation is 0w-20. Lexus has changed the oil spec for the 07 Lexus to 0W-20 synthetic.
So I use 0W-30 in both now.
You sure you don’t in fact mean 5w20 . . . ?!
I never heard of 3w-30
I’ve also never heard of 0w-30 . . . but I’m willing to learn new things 
I think you very well may be on to something here. It makes sense.
Keep an eye on your oil level, and check the codes like Tester said.
At your next change, use what the manufacturer recommends in the manual.
typo - It’s 0w-20

Thank you . . . I haven’t yet seen that on any shelves
Considering it’s for extended intervals, it might soon be popular
I have no problem finding it at WalMart or even Pep-Boys. Maybe because it’s the North East.
OW30 might be a good winter oil for the Camaro.
