#1866 of 1887 2011 Odyssey 6 speed mileage
Oct 15, 2010 (8:09 am)
I would like to know how close the new 6 speed mileage figures are to the window sticker numbers. I know a new engine mileage won't be quite as good as later, but I would just like to get a feel for the real world numbers. Thanks.

Returned a week ago from 11-day road trip from Twin Cities, MN to Colorado Rockies and plateau regions of southwest Colorado and southeast Utah. Lots of mountain driving including numerous stops for trails and overlooks. Averaged 25.58 mpg for trip including 3 tanks at over 28 mpg. Very nice ride.
#1868 of 1887 24.6 up, 26.2 down
Oct 19, 2010 (8:56 am)
2007 Sienna LE FWD.
Driving up from MD to CT, in heavy rain, at a brisk pace since traffic was light, we got 24.6mpg. I must have averaged 78mph, though.
Coming back we took it slow, my wife drove a bunch. Managed a much better 26.2mpg.
Van was pretty loaded up with gifts and gear.
Funny, though, how much better the mileage is when you're doing 65-70 instead of 75-80.

Like ateixetra, I also discovered what a huge difference only a few miles per hour makes on gas mileage. Since we had an easy schedule, I did some experimenting and discovered ours loves 69 mph at 1750 rpm. Even with the speed limit at 75, we found lots of other drivers doing the same thing (which is what made me try it, too) and we never held up anyone. If we were passing a truck and someone came up fast behind, I stepped on to finish the pass and get out of the way, but those occurrences were few and far between.
#1870 of 1887 Frontal area

These vans have bad aerodynamics (relatively)...the large frontal area adds an increasing drag at highway speeds.
I too find a large difference between 65 and 75+ (05 Quest SE).
I recall a test a while ago...which showed how UNUSED roof-racks can cause a decrease of ~10% mpg.
It's hard to 'hold back' when you have the last few miles...you're tired, kids are whiny, wife keeps asking to stop to get a drink, you're getting close to midnight and you have to work the next day. A quick calculation in your head...ok...i'll spend the extra $3 and push it to 75

For me, the trick it to be going fast enough that it stays in the tallest gear, no downshifts required, and the torque converter remains locked up.
My Sienna goes in to overdrive at about 46mph with no load, but up hills it will often shift down. So you really need to be going 55-60mpg or so to keep it in overdrive.
I'm sure the speed will vary for any given model, but that's the sweet spot for me.

Never has gotten over 20mpg. We are very disappointed.

I never see over 20mpg in combined driving (05 Quest SE).
The only time my average is over 20mpg is when there is a lengthly highway trip.
We have too many short trips where you 'gun' it to highway speed only for a couple miles; as well as too much time sitting idling.
If I were to guess what the 'trip-mpg' reads right now it would probably show16mpg or so.
Usually the Sienna highway mpg posted here is pretty impressive...usually higher than I get.

Something is wrong - I have never had a full tank average less than 20mpg, not once. Even in winter, in-town driving. 2007 Sienna FWD 3.5l V6.
Have your previous cars done OK relative to what other were getting?

Maybe you've gotten lucky
Your EPA shows 17/24
If you sit idling you're getting 0 mpg (suppose I'm stating the obvious)...so I can see getting in the teens if you're idling waiting for kids, fast food, prescription, atm, etc...
Not to say something isn't wrong with the Van...could be.
