On my daily driving cycle I am getting arouns 24 MPG. I drive 45 miles to work and 45 miles back, with at least 10 miles in stop and go before I hit the highway, so I am happy with mine. On I-10 driving to AZ I averaged 29 on the way there and about the same on the way back. At least 80MPH for most of the trip s9ince the speed limit is 75 for most of the trip.
