"Somebody who has a little more knowledge on why "winter-blend" hurts mileage I'd love to hear it. I tried to find a link that I looked at a long time ago, but was unsuccessful."
 
If I remember it correctly, winter blend generally has more slightly more ethanol, which in thermodynamic terms produces less heat energy per unit volume than gasoline.

That is really low. One person suggested to me once to start with a clean slate by disengaging the batter terminal (1 minute) to reset the computer's mixture memory; drive with a light foot for the next 100 miles; and, switch gas stations.
 
TO ALL. MY 08 Accord EX 4cyl. First tank (not from dealer). 24.5 MPG with combined city highway of about 40/60 est.

I believe it's because liter-for-liter, ethanol has less energy stored in its chemical bonds than gasoline. Winter blend simply has slightly higher levels of ethanol. Why this is so, I don't know.

I have a 2004 EX-L V6 Accord Sedan in which I use premium fuel. In a mix of about 50-50 highway and city driving, I can get about 24mpg. On straight highway, I get about 33 mpg maintaining in between 70 and 75. Its all about just maintaining a constant speed as much as possible.

Premium won't give you superior fuel mileage to regular blend gas, just a little heads up in the era of $3.50 premium.
 
And, like you, I agree that keeping steady speeds, even as high as 70-75 MPH, will help keep MPG up. I have a 4-cyl version of your car and get from 37-40 MPG at 70-75 MPH. On regular, no less!

I have the 03 EX V6, and you can get that same mileage with regular gas. Save your $$. $3.24/gal is enough.

Mileage with this car is disappointing. My history with Hondas is that they generally did at least as well as EPA if not better. 24.5 on a 250 mile trip at 70-75. Same trip with our 2004 EX V6 Coupe? 29 MPG. The VCM may or may not be economical - can you imagine the mileage without it?

04 V6 vs 08 V6. The 08 has a larger engine, more weight, and more drag (with the large front end). It would take a lot of time running on 3 and 4 cylinders to make up for all of that, IMO. I'll stick with my 03 V6. The extra rear seat room in the 08 is not worth it to me.

Many do not realize, the the Honda engine takes a quite awhile to break-in. I did notice an improvement on my 06 between 12k and perhaps 20k or so miles. Plus then engine now is even smoother and has a little more power now that it has nearly 33k on it. My mileage improved quite a bit. So try not to be really quick to judge the mileage too crucially, keep track but keep this all in mind. I would not say this if it were not true, this has all happened in my experience, and now I am very impressed with the engine and mileage.
 
Even a dealer told me, when I test drove another 4cyl accord that my 4cyl is going to feel faster or quicker than a brand new one that only has 10 miles on it, maybe even one that has only 3k, like this 08 accord demo had, and my 06 4cyl was much quicker, but with that said, and the fact it probably has slightly different power points in the band, in which I did not have time to feel out.
 
So hang in there, it really does get better with more mileage. believe me, there were times, when I though as far as power, it lacked at first, but it truly opened up as the mileage increased and I love it!! Once it really unwinds, your mileage will show true numbers.

At 7,074 miles
 
Best tank: 26.3 mpg
Worst tank: 16.1 mpg
Average mpg: 21.4 mpg
 
Our 2008 Accord’s EPA estimates are 19 mpg city, 29 mpg highway and 22 mpg combined.
 
Doesn't look too good to me, and confirms my experiences so far.
