    I performed the test (210 mile round trip) as you have stated except I had a constant 70 instead of 65, and the only stop was to turn around on the freeway. I will wait until I have 7500 miles on the van and try again.

    Has 2 separate readings: One for Instant (last 5 or 10 seconds) and one for average since the trip computer was last set.

         The 2005 DC minivans do NOT have the Instant reading and it may have been deleted in 2004. The Sienna Trip Computer still has both readings.

         The complete overhead console that has compass & outside temperature + Trip Computer is one feature the DC minivans and the Sienna have that I wish the Odyssey had.

         However, the 2005 Odyssey is superior to all minivans in every other way (except for PAX tires in the Touring).

    Thanks. I was curious.


    I do like the idea of averaging 5 tankfuls.
  • dudleyrdudleyr Posts: 3,469
    Averaging helps even out the filling errors, but it is hard to get a true highway number with 5 tanks of gas - unless you are driving cross country.


    Try the 210 mile trip again at 60 mph (boring I know, but it should give you some good data), and see what difference it makes. There is a speed above which the 3 cylinders do not shut down. Was the green eco light on the whole time?
  • The ECO light is not on very often at all. In fact it is almost impossible to drive and maintain the light on.

    I think this may be part of the problem but the dealership won't look at it until I have 7500 miles. Plus I don't think the dealership has any experience with the VCM. I'll do a similar trip when I get to 7,000 miles or so.

    My trip computer shows average 13-14 MPG. Very upsetting, but I know it's still new (700 miles) and mostly city driving.


    Today I drove on the palisades parkway in upstate NY, and I did a "reset" on my average mpg computer, and traveled 55-60 mph (set the cruise). The whole way it was showing between 27-31 mpg! Same on the way back.


    When I arrived in the city (stop and go traffic) it was falling to 21-22 mpg.


    I don't believe it's true (it's too good to be true), but Hansienna mentioned above that the trip computer from DC vans are very accurate. I would love that should be the truth.


    But usually in daily driving I let my car warm-up (it's too cold for me to let the car warm-up on the way - how do you people manage to get in the car in those cold mornings without warming up the car for at-least 5-10 minutes?) and doing mostly city driving, so maybe that's way it gives me usually about 14 mpg.

    "- how do you people manage to get in the car in those cold mornings without warming up the car for at-least 5-10 minutes?"

    Easy. Just do it and tell yourself not to be a sissy. It all depends on what you're used to -- my point of refernce is still a ten-speed bike... that DOES get a little nippy when it's 20 deg F outside!

    Warming up your engine in the driveway isn't as bad today as it was when cars had carburetors, but I don't even want to do that to my beater cars, never mind the nice ones...

    You have to be from NYC. Only the city folks consider the PIP to be in "upstate" NY!


    I grew up in Rockland county, which isn't upstate either, so I have experience with this matter.

    Hi all,

    I just bought a used T&C yesterday with All Wheel Drive and 29000 miles on it. Original specs were 17 city/22 highway. After about 150 miles of mostly mixed city/suburban highway driving with some stops and a little idling I am getting just over 20 mpg based on the trip computer. I will report back when I have done a few tankfuls.

    I appreciate the comments early that the Chrysler trip computer is accurate on MPG. It doesn't seem the same can be said for the Miles til Empty display. When I filled up the tank yesterday the display told me I had 238 miles til empty on a 20 gallon tank!! Now after 120 plus miles it's telling me I have about 180 miles left. Seems with a 20mpg average it should be telling me about 280 miles left. (20x20=400 miles). Again I'll give it a couple tankfuls and see what happens.

  • samnoesamnoe Posts: 731
    He he... I grew up in NYC - I live now in Rockland and consider it as upstate - compared to NYC... isn't it?


    Once you pass the GW bridge, all of a sudden the heavy traffic, aggressive driving stops...

    You must not spend much time around Fort Lee, or the PIP at rush hour.

    Son has a '04 Sienna with under 10K miles. He is not happy with MPG. Would like a lot of real world comparisons, the more the better. On my '04 Odyssey got 25 ish MPG from Phoenix to San Jose doing around 75 MPH most all the way.

    I'm generally not too happy with the mileage. My prior 2000 Sienna LE got @24-25 and I was hoping for same or better with newer tech engine. My "stupid" computer says around 24-27 average. However actual averages from 8/29/04 to 12/17/04 (mostly within the Tidewater region of VA) are from a low of 19.3 to a high of 22.7 (drove extremely conservative that tank [extremely boring!]. I probably drive highway 75% of the time. Also, I've put a lot of miles > 30,000 and mileage has not improved. I guess it's due to AWD; which incidentally I hate since is has NO SPARE due to run flat technology. We had a flat (and drove it on the flat a lot... local dealer I bought from did not have spare tire; a dealer across town had one for @ $250; but could not mount it and sent me to Sears to get it mounted for another $50. Also, I've reported computer miscalculation to dealer on numerous occasions and they say it is within spec. I'm glad Toyota doesn't make medical equipment or equipment for NASA. I'd be interested in knowing how you other SIENNA AWD owners are doing out there both in terms of mileage, the trip computer and AWD. By the way, Edmunds Town Hall Rocks!

    Have been reading the owners comments on both Clubs S/O's. Ody's VCM is not capable of off setting it's additional curb weight. No current non hybrid 4600lb. "mini van" is capable of 28 MPG highway even if it was built by NASA! Remember that curb weight is only 500-600lbs. below a full size SUV! No Ody owner has reported more than 24 at ideal (perfect) highway speed (less than 60mph) and conditions. VCM is of no value in 80% of normal driving fuel consumption. So what you have is a heavy not very aero dynamic vehicle working within physics as we know it.


    Sienna FWD's seem to hit 24-26 mpg at various highway speeds. Drive train seems to be more forgiving. Sienna weights about 4100lbs. Under ideal conditions some owners report 27.5 mpg. Sienna is simply lighter and operates a smaller more efficient V6.
  • I have over 2000 miles on my '05 odyssey. Mostly around town miles, but have had several 40 minute (1 way)runs on I95. After averaging out gas mileage over last 5 tanks, my average is 15.4. Very disheartening. On one I95 run, the MPG computer got up to 16.6. The ECO light was on almost the entire run. This was averaged into the 5 tank average of 15.4. I can't understand why it takes 7500 miles to see better gas mileage. My Quest had 22mpg on the same 40 minute I95 run when it had only 1300 miles on it. The ECO option and advertised higher gas mileage was a deciding factor in buying the odyssey. Will take the "advertised" mpg with a grain of salt when purchasing my next vehicle, and will listen to other vehicle owners first.
  • we did a 340 mile trip yesterday, 3 adults and 2 kids, 90% highway at 70 mph, and our '02 MPV with 27k miles gave us 27.4 mpg.


    Very pleased, I was expecting about mid 20's.

    19.3 to 22.7 for and AWD minivan the size and weight of the Sienna is not too shabby, IMO. I'm getting these numbers, and I'm very satisfied. Do you realize how many SUV drivers are getting substantially less MPG, while settling for less interior room and passenger capability?


    Your expectations are too high. The mileage you and I are getting is remarkable, considering the AWD and passenger capability.

    We own a 2005 Odyssey EX (w/o VCM) and did manage just shy of 26 MPG on one trip in our first 2000 miles of ownership. Driving conditions were favorable averaging 70 MPH over 300 miles of highway driving. We're getting 15-18 MPG in city driving which I hope improves. Overall we're marginally satisfied with our gas mileage but are hoping we see it creep higher throughout our 1st 10k miles like some have suggested is likely to occur.
  • aokiaoki Posts: 11
    FYI, my 98 T & C LXi with the 3.8L 180 hp v6 has been getting the same gas mileage you're reporting which is nowhere near the EPA ratings of 17 city and 24 highway. I was very disappointed at first but learned to accept the van for its many useful features. Best ever tankful was 25 mpg with a 25mph tailwind--all highway. Worst ever was 11 mpg with 100% city driving in San Francisco--major stop and go plus hills galore.


    I just learned to enjoy the vehicle for its utility, style, features, etc. and not to focus so much on its gas mileage issues since, in my case, they weren't caused by any identifiable mechanical malfunctions.
  • Well - I have an 05 Ody EXL (VCM) with under 1,000 miles. The 1st tank of mixed driving was right at 19 MPG. This included demo-ing the vehicle to friends and neighbors (Nav and Res), etc. so there was more than the normal engine idling. We had a little freeway trip to take for New Years and I wanted to check on the mileage so I filled up at the start and refilled at the same pump at the same station when returning. We traveled 194 miles and used 8.2 gallons of 87 for +- 23.7 MPG. On level ground at +- 70 MPH, the ECO light was on most of the way. This is with 2 adults, two teenagers, and lots of luggage. Very little stop and go for this trip but hard rain on the 1st leg. Overall, I have been impressed with the mileage as compared to my old T&C. Our 4cyl Accord delivers 29-31 for this same trip so, again, not too bad for this new big boy.
  • 1st tank from dealer got 21.7 MPG. The 2nd tank I got 22.7MPG and I have less than 800 miles.

    I have had 4 Quest or Mercury Villager Vans, and they all have served me well.

    I recently traded my '99 for a 2004.

    The '99 had over 103,000 miles on it. I keep a record of all my gas purchases and make a spread sheet at the end of the year.


    '93 Mercury Villager 24.0 mpg

    '95 Mercury Villager 24.03

    '99 Quest 22.4 mpg for 103,000 miles.

    '04 Quest 22.08 mpg for 10,137 miles.


    The computer read-out seldom agrees with the calculation by pencil. It is usually more optimistic than the actual mileage.

    My driving is mostly rural with a few long trips. I made more long trips on the '93 and '95 than I have on the others, because I used those for business travel. Since I retired my highway mileage is a little less.

     I live in a rural, mountainous area 14 miles from a grocery store, church, etc.. Most of my mileage would be considered road mileage, but not necessarily highway (long trip).


    I recently learned an interesting fact about the tire pressure monitoring system on the '04. The valve stem has a small transmitter that sends out the tire pressure readings.

    At the altitude where I live, the pressure displayed is about 4 pounds less than actual.

    I was told by a service man at the dealer that if I lived in Denver the pressure would read correctly. He knew of no way to re calibrate the readings. Also, the readings are random according to the manual and do not correlate with any specific wheel position on the car.
  • The first recorded mileage of my van was 21. That was under 500 miles with 70% on a highway mix.
  • marine2marine2 Posts: 1,155
    checked your mileage with a pen to see how accurate your mileage really is? I don't think you can really get a accurate count unless you do it by hand.


    My Dodge mini van only has 95 miles on it, so I'm not even going to try and check it until I get more miles on it.
  • steverstever Posts: 52,572
    I haven't updated my spreadsheet for my '99 Quest since it was at 93,000 miles back in June (just over 100,000 on it now). My lifetime average is 21.33. The first 33k were highway miles but most since then has been suburban driving.


    Marine2, I've been manually keeping a gas record book in my cars since 1974 or so. Excel sure makes it easier to add it up though!

    While many complain about dismal gas mileage in their Sedona's I am getting what the EPA estimates. On a recent tank with 90% highway we achieved 23 MPG(our best tank ever) Around town mileage drops to about 16 or 17.

    2005 Sienna XLE Limited, mileage while driving easy, breaking car in: 1st tank 21 mpg (highway & city). 2nd tank 24.7 mpg (country roads). 4th tank 23.5 mpg (all flat highway, 60-65 mph in the rain). By the way, the laser cruise control is to die for.
  • What is "laser cruise control"? I don't have a Sienna but love all new gadgets.
  • rorrrorr Posts: 3,630
    'Laser Cruise Control' uses a laser to constantly monitor the distance between the front of your car and the rear of other cars on the road ahead. If the space drops below a certain distance, the cruise control automatically either drops the vehicle speed or applies the brakes. If you change lanes (for instance, overtaking a slower vehicle on the interstate), the laser cruise control then detects that the space between you and the next car ahead has increased, and the cruise control will raise the speed back up to the preset level.


    How well it works seems to be a matter of opinion. Some highway situations apparently 'fool' the cruise control into applying the brakes when it is unneccesary.
  • Thanks for the info. So does it grow out of "backup sensor" technology?
