Those are some great numbers considering how new your HHR is. They get better as time goes by. Thanks for letting us know you have a 5-speed. I have often asked people boasting high mileage if they had an automatic or a stick and never get a reply. Even though both have the same mileage ratings, it still makes a difference.
I'm a careful driver (most times) and try hard to get better mpg. I get better MPG driving my wifes car then she dose and it really gets here P.O.'ed.

As a witness to hundreds of GM's mileage testings, I can tell you, "THAT IS ABSOLUTELY FALSE IN REGARD TO GM". At least up until 7 years ago.
I was responsible for the construction of 5 of the testing cells at the GM Desert Proving Ground. The cost, because of the need for absolute precision, was unbelieveable.
If you are interested, I can describe the prescision and method of testing. PM me.
