If you take it on the highway and run it between milemarkers, does the odometer get one mile for one mile travelled? You will need to use one of the trip meters to check it. You may need to go like 10 miles to see if it starts creeping off. Also if this is the problem, Your indicated speed will be off.
As far as the increase in mileage due to octane, I also run 87 regularly with no problems and get 20-22 city (a little less -19.5 ish- in the really cold weather due to warm-ups.) I have gotten on the highway, up to 33mpg. with an '06 2.4L.
The highbeam hesitation was discussed before. No fix for it that I know of.

If the DIC shows 31.6 mpg, then I would think thats what the average was.

RandyTheHack.....
You are obviously (by what you and how your are writing) do not understand the logics and algorithums of the MPG in the DIC. Your Owners Manual has a good description, I suggest you try that.
It's either that or you are not manually calculating correctly (or a combination of both). I mean gosh, common sense, and you should understand this owning a diesel, would dictate that if your wife drives the vehicle hard and easy and gets the same mileage, something is wrong with the calculation. IT'S NOT A DIESEL.
If you really want to determine the MPG by the DIC, I suggest you fill the tank at a station VERY NEAR (and I mean VERY ) an Interstate. Reset the entire DIC EXCEPT the oil life indiator, and hit the freeway for about 200 miles, using the Cruise Control (set it at 65-70.....these engines, because of the VVT, use more fuel above that). Turn around and return. Pull into the station and, at the pumps, check the DIC for MPG. Then you can calculate it manually after refilling the tank. There will be a slight variation between the DIC and the manual calculation due to ACTUAL FUEL USEAGE (whether you stop pumping at the "click" shut off or you stuff to the cap)......but it should be close.
DO NOT RESET OR ALTER THE ORIGINAL RESET UNTIL YOU COMPLETE THE TOTAL TRIP.
Let us know....

My thought too.
If you take it on the highway and run it between milemarkers, does the odometer get one mile for one mile travelled? You will need to use one of the trip meters to check it. You may need to go like 10 miles to see if it starts creeping off. Also if this is the problem, Your indicated speed will be off.

Now... I did not check distance between mile markers, but if I were off more than a foot or two, I would see speed differences; I do not. We can check this... I'll check it on the way up to the shop. It's about 35 miles north of here, so there will be plenty of opportunities to check it out.

You know, I would be happy with 22 mpg. I drive 18 miles a day to and from work, which 14 of it is interstate, I manage to get a resounding 18 mpg. My dealer say to bring it in, but they do not give out loaners for me to use to get home and to work. I really am starting to dislike my car.

I've been running 93 octane for the last 5 tankfuls. Still mixed city highway driving and still 30.2 mpg so no improvement over using regular 87 octane. My DIC reports mpg pretty accurately. I always reset it at fill ups.

Yes... Snoopy... I know something is wrong. Mileage when the wife drives her car easy and hard does vary, but only by a couple of mpg's. A harder driven tank typically results in 22 or so; a soft touch might make it up to 23-24 mpg, but that's it.
We have NEVER believed what DIC says on either the truck or the car... which is why we always hand calc the mileage.
