My neighbor and I both purchased 2007 Odysseys last year and both of us are getting 11-15 mpg in town and no more than 18-20 mpg on the freeway. I once got 23 mpg, but that was on a non-stop trip between Sacramento and LA. On the freeway I use cruise control and the ECO light is on most of the time. Any comments?

Recently on a long trip I got close to 26 on my 08 EXL. In city I get around 16. I have 1800 miles on my ody, so its quite new. I am not sure but it may improve.

We have 6800 miles, and still seeing bad mileage. Best we ever got was 21 on all highway. Usually around 12-14. Told by dealer to wait until 7500 miles - full break in period. Seeing too many similar comments on the web, so that seems to be the standard dealership lie (ooops - I mean line). I'm not a leadfoot driver. Probably 40% of my driving has been highway. Have kept track of all gallons purchased and miles driven to show at next oil change. VERY DISSAPOINTED

I have seen in some posts that people with non VCM engine, that is LX/EX get better mileage. That is why the made changes in next generation VCM in 08 model. Its possible, I am getting some what better mileage because of new VCM engine. Also one more thing is that EXL and Touring models are upto a few hundred pounds heavier that EX/LX models.

There was a recent question in Wall Street Journal about the poor gas milage on the new odyssey, the guy owned old odyssey before and got much better milage. I remember the answer was that Honda made the engineer more powerful and van safer but in the mean time the milage suffered.

I have 08 EXL and get little over 15 in city. We use it for short drives, so that is explainable. Been on long drive once and got close to 25.

When cruising down the highway recently, I noticed a distinct pattern in my mileage. When cruising on a level stretch, the mileage drops down to 12 mpg with ECO on. As I head up a small hill (e.g. approaching overpass), the mileage remains steady even though the vehicle is clearly working to maintain speed. About halfway up the hill, the ECO goes OFF and the mileage INCREASES to 14. At the top of the hill, the mileage begins a steady increase to > 30MPG. Once I'm clear and cruising steadily on the other side, it drops back down to 12.

Before anyone says "well, it's a 5000 lb vehicle with poor aerodynamics, etc. etc.." Note that I was able to get reasonable steady cruising mileage (25-30 MPG) by disengaging overdrive very briefly before re-engaging it. This would hold for anywhere from 5 to 15 seconds before dropping back down to 12.

This says to me that the sophisticated computers are getting just a bit confused. At this point, I think I'd be better off with a good old carburetor and vacuum advance.

We just bought a 2006 Oddysey EX-L, and it has/had the same problem. We bought it from a chevy dealer, and asked for it to be repaired, and the repair seemed to make it better, but it's not completely fixed. Apparently, they re-sealed the passenger mirror where it attaches to the door.
Good luck!

I have the exact same problem .
The fuel economy is better up a hill, or crusing at a high speed.
When I ease off the gas the fuel economy gets worse.

That makes no sense at all. You've got a problem with the ECU.

Just bought a used 07 ex-l and my first tank of mostly in town driving was 16.35 miles per gallon. Not sure how it is on a long freeway trip yet.

Our 2007 Odyssey gets 11mpg in town and 15 hwy. It has 73,000 miles on it. The older it gets, the worse the mileage. We've always had it serviced at Honda as did the previous owner. The dealership told us "all vehicles are different". My sticker said 19-26 though! Another gentleman in the service area with the same van as mine but an 2006 had the same problem. The mechanic heard my husband talking to him about the lousy mileage and told them that no one has ever complained about the mpg's on these vans. Yeah, right. I don't know what to do about it now. Is this "fixable" or is it just designed wrong?
