So I went for a drive this weekend to a little town I used to live in called Garden Valley, ID It is near 75 miles one way there, so I filled up the tank and wrote the mileage down, drove there, drove around alot while I was there and drove home, I checked the mileage and I had drove nearly 200 miles, 150 of it going 55-60 mph, Filled the tank again (Was a little under half), it was 8.06 gallons, did the math and highway driving I get roughly 25 mpg, a whole lot better than my 4wd Toyota, which was lucky to get 15-18.
