#1856 of 1887 2010 Sienna LE FWD 30.6 mpg for 440 miles
Aug 01, 2010 (7:15 am)
From Auburn,MA to Gaithersburg, MD approx 440 miles
maintained 63-65 mph. A/C on and off. Very light on pedal. Lifted foot off the pedal in the downhills. 60 mph uphills. No stomping the pedal.
Filled the tank before hitting hwy. Reset average mpg indicator.
The indicator showed 30.6 mpg when I arrived at dest.
I was averaging 32 mpg up until George Washington Bridge traffic few mins.
Fantastic for the size.
The best mileage spot is 64 mph
Same distance aggressive driving I got 24.5 mpg.

I have the same van...for me I do best around 50-55mph.
It shifts to overdrive at about 46mph under light loads, but at 50-55 it stays in 5th gear more of the time.
I've broken 30mpg only a couple of times in my '07. I'm too impatient and increase speeds most of the time.

2010 Odyssey bought on 08/13. I haven't filled the gas till now.
I see the meter going one point above E. I am surprised to the mileage is just 188.
I am not sure whether the dealer filled in the gas for full. After few minutes of delivery, i saw the gas level came down one quarter.
I drove most of it local miles.
How much can I expect for mileage. Do i expect little early on the performance. What should i do exactly to check the mileage.

It probably wasn't completely full, so ignore the first tankful.
Zero the odometer each time you fill up. Then you can calculate miles on the trip odo/gallons need to fill it back up, starting from the 2nd tank.
High-end models have trip computers that estimate the mileage, but some are optimistic.
#1861 of 1887 2007 Odyssey reduced gas mileage after transmission firmware update
Aug 20, 2010 (2:42 pm)
Last month my VSA modulator failed. Dealer replaced it and while the van was in they updated the judder (transmission firmware). Since then I have noticed the torque converter does not lock in OD until 52mph. Unlocks below 52. RPM jumps 200-300. Overall the RPMs run higher. First tank had 240 hwy miles and 127 city. Most of the city driving is 40-45. Even in 35 zone I run up to 42 to shift to OD and back down to 40. Then keep a light foot on the gas so the eco light stays on. I was expecting 22-23mpg but only showed 19.
Second check was at 187 miles with 140 hwy. Some of the hwy was FM roads that varied from 60-45. Very annoying to see the rpms jump at 51mph on flat roads. MPG was 20.
My hwy mpg has been as high as 30.7. Varied from 26-29 mostly. Now I doubt it will ever get to 25 unless the trip is constantly above 52mph.
Has anyone had the judder update and noticed a decrease in fuel economy?

Odyssey mileage typically increases with miles. It may take as many as 10,000 miles to optimize. In-town mileage, regardless of mileage, is never going to be great.
Was delighted that the first tank on my new '10 EX-L yielded about 22. Although many of the miles were on the highway, I did lots of varying the revs in the process of breaking in the motor. Although some may poo-poo that notion, I still adhere to the idea of avoiding steady RPMs for the first 500 miles.
#1863 of 1887 Around Town, then a road trip...
Aug 25, 2010 (9:49 am)
Two tanks on my 07 Sienna LE FWD:
First was 29.9 mpg, all highway, from DC to the shore. Light traffic helped. Can't believe I didn't get 30!
Next I got 22.9 mpg driving around town, while at the beach.

i too just purchased 2010 odyssey ex-l, and thought that the dealer didn't top it off very well so I went to put more gas in. When the pump initially clicked off, i proceeded to put another gallon in. after driving it only 110 miles, the gauge showed just above 1/2 tank-- this concerned me-- i thought that i was only going to get about 10-11 mpg. I went back and re-filled the tank but this time took my time to fill it up until I saw the gas. This is what surprised me-- after the pump turned off initially, I was able to put in an additional 5 gallons!!! So now we'll see what my actuall mpg is.

Wonder why that's happening.
Mine doesn't need to be topped off - it fills up every time, the first time.
It's risky because you can damage emissions equipment if you top off too much.
