Sounds fine to me.
I pulled an average of 28MPG in my 1LT over the course of 240 miles. That was with the cruise control set at 75MPH with the AC on, passenger, and car full of stuff. Going through the rolling hills of southern and central MS.
I noted that it will hold a constant 31 MPG with the cruise set at 70 MPH, AC on, passenger.
Oh, and it will hold 25.5 MPG with the speedo at 91MPH......
