30.2 mostly highway, a little stop and go on the daily commute this week. I drive 55-70 depending on the flow of traffic. On my road trips to PA I usually average about 32.7.

I have an '05 G6 GT with approximately 28,000 miles on it (bought it used a few months ago with only 19,000 on it).

sucky 17.6 around town and last week got 27-28 on interstate. Anyone ever notice that the MGP's go down to like 9-10 going up hill? that's like worse than a shevy 350..

You have to realize that they measure MPG on a flat road. Put that same Chevy 350 up that same road and you'd probably be making 4 MPG. I get about 15 MPG going up big hills but going down the other side of the hills kinda even it out.
