Premium is recommended for the 2.4, not required. The only reason I use it is for the improved performance and slight savings with the increased mileage. I had a Cadillac that was also "premium optional". I noticed no performance or mileage difference, just that it ran rough with regular, so we comprimised and ran mid-grade.
There is no compelling reason to run premium in an engine that isn't tuned to make use of it. So I would not bother if we would have had the 2.2.

I've driven both. In day to day "on the street" driving, you will probalby not notice much difference. Where I notice it is in freeway driving, which I have to do every day. At freeway speeds, accelerating is just plain better. You do have to use premium in the 2.4 to get the most out of it. We jumped from 24.7 mpg to 26.7 by using premium, which for me is about $100 per year cheaper at the prices we're paying today. My average mileage is a mix of city and freeway, and I drive it pretty hard to. I haven't been able to get a read on "straight freeway" yet. We're taking a short trip next week and I'll check it then.
So for me, the 2.4 is the better choice. What we really wanted was the other features of the 2LT, so we ended up with the 2.4, but I'm sure we would have been happy with the 2.2.

2009 2.2L will be 155hp with Variable valve timming. 150 foot lbs tourqe.
Maybe that will change some peoples decision. Could be a slight increase in mileage as a bonus. Have to wait to find out.
Chevrolet info says use premium fuel for best performance on the 2.4L
2009 will all be E 85 useable as well. "Bah Humbug" on that idea.
They just have to be competative with others offering E 85 and look like they want to help save the planet. E85 is still burning the fuel.
Lets get onto the real deal.....Electric and fuel cells.
