I am getting 19 in combo driving - mostly around town, some freeway.
I haven't really taken any long freeway trips, so cannot comment what that mileage is. On my first trip to THill with about 1K miles on it I think I got around 24-25 doing around 80mph. Prolly better as the engine breaks in. I now have 4K miles.
I don't use the DIC to measure fuel mileage because it's off by about .7 - 1.1 MPG vs. actual computed mileage. I got 20.41 on my last tank that was 60% highway, 40% city. My computed average over the last 11,000 miles is 19.43.
