I am driving a 2009 HHR now as a rental while my car is in the shop for warranty work and it has the 2.2 engine. With 149HP, this must be the same engine Saturn uses as the HHR drives a lot like our old VUE did.

Replying to: draymond2 (Dec 28, 2008 7:33 am) Since we got our car 4 months ago, I can promise you this ....you WILL motice a harder feel and the knocking mentioned if you do not put premium fuel in the 2.4. as it details in the manual. I did not realize this when I first bought it and was complaining ab my mpg. After i fixed the error, my mpg is now where it supposed to be , even better . So you are not really paying more if your gas milage increases. If you do the math, it comes out right. i dont have any figures in front of me and I appologize for that,.but im on the rn this morning! But all in all, using the premium has not been a problem or cost us any more. god luck
