I didn't realize about the premium gasoline until I read these threads here. As I mentioned before, my best friend used to be an engineer at Exxon/Mobil and he told me never to use the higher octane gas until your car "needed" it because once you start using it, you will have problems if you ever go back to 87. After reading these threads on fuel economy, I noticed my car was missing a little when I accelerated going up hills. (Never had any knocking or any other acceleration issues. Just on hills.) I asked him about it, and he told me to check my manual and if the manufacturer "recommended" higher octane gas to put what it said in there and never change back. I put 93 octane in on my last tank, and I am already noticing an increase in MPG of a few miles, not to mention no more acceleration issues.
 
Also, to touch on what the last poster said, my co-worker's husband is a GM master mechanic at a Chevy dealership, and he said it matters less what octane of gas you put in and more of where you are getting your gas. He said it is more important to get high quality gas and avoid the cheaper gas stations.
 
I never bought a Cavalier with the 2.4L engine, but I can't imagine having an HHR with a 2.2L. It just seems like with the greater curb weight it makes sense to have a little bigger engine for more pick-up.

I have a 2007 LT2 that has the 2.4 and is closing in on 100,000 miles. Other than the heater fan "bird chirp" that every GM car I have owned in the last 20 years has had I have no complaints.
 
Costco for gas and get 26-28 in everyday use, about 30-32 on the interstate.
 
I like it so much I am hunting for a low mile 2011 so I can keep one around for a lot longer.

Pretty much the same m/p/g here with my 2010 2.4L with 25,000 miles on.
   To bad the last production line are the 2011 models.
   Probably it was to good G.M. had to stop building them?
   Looking towards the new Chevrolet Trax or the Sonic "Hatchback" but only in 2015/16 otherwise it would have been another HHR.
