Both my 92 and 03 Accords had/have the wind buffeting, if only the rear windows are open. I think if the rear of the car is slightly wider than the front, it makes the buffeting worse. It's like the air keeps being forced toward the rear windshield, and has a hard time getting out, if the front windows are not open.
 
As far as the fuel mileage thing, I'm not going to sweat, or deal with wind noise at 65mph or more, to save a couple miles per gallon. There's a limit to my frugalness. I will only ride with the windows down, at low speeds, and if the temperature is comfortable.

I can understand what you are saying. (some habits for me are hard to break!) But this brings up something I have not thought about or tried. I wonder if the compressor goes on and off like the older versions do? (I am assuming so) and if that is the case, how will that match up with the VCM? The car may not stop "moving" or "changing" while on the highway with the A/C on. Between the VCM changing and the AC going off and on, I may go mad. I'll have to try this tomorrow and see what happens.

I went out to the website that you set the link for. It was interesting. The part I found to be most interesting was the short-shift/WOT, does this only work for manuals or does it work with automatic?
 
The impression I got from it was to take off as fast as you can and then stay at the speed you want once reached, is this what that part of the article might mean?
 
I don't have an 08, but I thought I'd share my thoughts on the article.

I don't have an 08 either and I haven't read that entire article for awhile. I do remember thinking it a bit odd to accelerate that fast too. I always thought that jack rabbit starts were bad. I know one should get up to speed fairly quickly and then try to maintain it, but wide open??
 
One of the challenges of an automatic is to stay in the highest gear on the highway. That means anticipating hills so that your car doesn't downshift. Maintaining how hard your engine is working is probably more important than maintaining a certain speed.

I don't have the dual A/C ('07 SE MT) but when I have cruise control on and I am driving on a pool table flat stretch, I can watch the scangauge stay steady at 40 mpg for a few minutes then suddenly drop down to 34 mpg for a few minutes and repeat this cycle indefinately. When I turn the A/C off the mileage will just stay at around 40. This behavior leads me to believe the compressor is cycling.
 
Also the compressor only runs without consent when in one of the two defog modes - and there is a hack to prevent this for the 2003-2007 models. This is all for the basic climate control, not sure about the dual/automatic.

You are really taking your assumptions extremely far with your guesses about getting about 40 mpg from the 31.8 you actually saw.

True. Just really wanted to make the point that I got 31.8 from the V6 without any effort to maximize my mpg, so it could have been even better.

3rd measured tank was 23.8 (1300 miles on car now) - So I've had 24.5, 22.16, and 23.8 = averages out to 23.48 - I would say 60-70% highway - I have a trip coming end of this month that will be 400 miles highway each way so I'll see how well it does on mostly highway - that is if I don't trade it off before then

Honda Accord - HUGE Mileage improvement by sealion

03 Accord EX (4-Cyl) with ~60K miles. I bought it used a couple of years ago.
 
I have an habit of obsessively monitoring my mileage - not for cost, it's just one of those things I do. At first I was getting:
~24mpg in city-highway mix
~28mpg when it was mostly highway
~31mpg when all highway
 
But recently the mileage really dropped, getting down to 19 - 20mpg. Did the usual things (air filter, fuel injection cleaner, spark plug check etc) didn't help.
 
Finally, I decided to give a different gas station than my usual one a try, and boy did it make a difference. Immediately went up to 23 mpg and it has been at 25mpg the last 4 times I have filled up.
 
Granted the 19 mpg range was in one of the worst Iowa winters I have seen. But I also switched gas stations in February when it was still cold.
 
My advice if you are getting inexplicably low mileage for your model, try different gas stations and avoid the "discount" ones. My $0.05 member discount definitely wasn't worth it. Not to mention the damage it might do to the engine.
