28 MPG at 60 MPH????
During the winter of this year, when I drove on highway, I always got 22-24 MPG, which I think it is enough high. Because the specification only lists 21 for AWD.
These days, when I drove on highway, I found I could get incredible 26-28 MPG. Is there anyone else get similar MPG?

I have, I had my little cousins in the back, so for the first time ever I wasn't speeding, usually I would be in the fast lane going 85-90 but with the little one's i was going 60-65 and averaged nearly 28, if I remember correctly it was 27.5.
It's possible, but you have to be driving it easy. I usually don't ever drive it easy though, but still manage 23 mpg (or more) on the highway on trips to Michigan going about 90mph (with mountains) route 80 has a bunch of mountains as soon as Pennsylvania starts, but then it starts to flatten out once you get 50 miles into Pennsylvania.

I can get around 25-27mpg if I keep my foot out of it on the highway. It seems like the slower you go, the better the gas mileage. So 60 getting really good mileage makes sense to me. Hardly ever drive like that though.

Yeah, only mostly when out of state though like on road trips (every month, plus you can't get points on the license when out of state). I haven't had a ticket (well, only one it was for a rear brake light) in my entire life, nor have I been involved in a car accident. I drive safely, and when the roads are wide open and the skies are clear, why not! Nothing wrong with going 85 or 90 if not more sometimes, as long as your doing it responsibly.

60/65 mph is the most efficient speed on most vehicles (ie. not hybrid). That's when the car's aerodynamics are the best possible, as long as there are no cross winds.

You're not alone.
In fact, you can get over 30 MPG, under perfect conditions. My wife was following me in the 40' diesel pusher motorhome, from Vegas to Colorado, and because 275 HP/660 lb. ft. machines which weigh 28K lbs. are a bit slow, she managed one tank of 31.5, then another of 32 even. This was UT/CO.
High elevation leans the motor out even more, and backing off shuts the injectors off above a certain RPM. Probably around 1,400 or so. Coasting in-gear is often times 'free MPG'.
edit: The car's MPG readout was verified via miles/gallons and a calculator. Still amazes me, to this day.
