Wow, that's a pretty good average. I think the highest I've gotten to is around 29

Mine was 28.9 from Las Vegas to LA. Between 80 and mostly 90mph occasionally more. Impressive. Several traffic backups in the route. Only one full throttle run out.

Sadly I've never gotten above 14 mpg in the six months I've had the car. (I drive very little; mostly short trips where the car barely has time to warm up before I get back home).

I saw 24.9 coming from Columbus, OH to Philly. My typical average is between 18 - 19 mpg.

I drove cross country. Best was in the midwest where I got 30 to 31 mpg. Lowest I got was about 27mpg

Don't remember, but that portion of the road on I40 heading east , the trip gets my best MPG. My LS 430 did it's best mpg there too. I have made the trip multiple times. Maybe it's got a good tailwind or something there.

My best is 28.3 in my 07. But I have recorded temperatures substantially higher than 59.

I filled up the day before and had done 95% freeway driving for maybe only 35 miles or so.

Dude...you're taking this VERY well. He's spending 3 dollars less per month on fuel than you!

No pictures, but I did manage 29.2 from San Antonio to Fort Worth, 80-85, A/C on, though it was December (it was still 75-80F).

I've also gotten just over 600 miles, I think it was 604, on a tank. Denver to Chillicothe, TX. A/C on only part of the time, but way elevated speeds for about 200 of those 600 miles.

There are areas of this country where there is truly nothing. US-87/287 through NM, I'm looking at you.

Sounds like part of Canada...from Alberta to Ontario....thousands of miles of NOTHING, except wheat fields. And VERY flat.

Don't forget soybeans!

When driving across Canada from PEI back to the U.S. west, we made it a little into Saskatchewan when we decided, that was enough, and we went south, over dirt roads (in a 40' diesel pusher coach, pulling a 4x4) to North Dakota.

To be fair, when the wind was right, the soybeans plants, well, their flowers, looked like water...all the way to the horizon.

Still, Canadian 'middle of nowhere' positively shames anything in the U.S., and we've been to most of those places in the U.S. (those accessible by wheel, at least).
