I am seriously considering a 2008 SS Impala for my wife and was curious whether it needs premium fuel. Anything bad I should know before diving in?

2008 Ss

The manual "recommends 91 octane but says you can run 87 with slightly reduced acceleration". Haven't tried anything but premium but I've only had my 08 for a week.

Sounds like my wife's Acura. It will run on the cheap stuff, but there's a reduction in power and gas mileage. I know you've only been in it for a week, but how's the mileage so far? This is my biggest concern as 16 mpg city is livable at $3.00 a gallon, but not so much at $4.00.
