Honda Odyssey Real World MPG

    You are correct, bad move IMO, but I think after the transmission woes of the previous generation and the fact that this is their first 6AT they probably wanted to limit their case things go wrong again. I think that 5AT transmission has cost them a lot of $$$!
  • As for fouling the injectors plugs etc etc . According to what others have reported on the other forum the big improvement that the TC-W3 oil does is cleans the top end . I haven't tried it long enough to report on this, however what I have noticed is quicker starts and better performance.

    You are correct on the 22.4 MP- US Gal.
    the 28 + MPG was total average on the 2100 miles.
    My best mileage was on the one tank full that I drove 90% of it at 60-65 MPH
    on secondary roads from Panama City Florida to Jesup, GA

    The link is very interesting with a lot of feed back well worth checking out.
    It seems that the only negative feed back is from the ones that didn't stick to the instructions of 1oz to 5 gal ratio.

    We have an '02 LX that still gets about 23 mpg (But thank you Honda for the failed transmission). I have an '08 that gets 24mpg (both numbers are for highway. City about 18 on both. The '02 has a K&N air filter and I just bought the K&N for the '08. I am a true believer in synthetic oil and K&N air filters to give you slightly better performance all around. Wife is looking at an '11, but afraid of the 6AT b/c as someone else mentioned previously, maybe the trans will be faulty. Who knows.

    I have a 2009 Odyssey and the sticker for EPA mileage was 17/25. I was expecting it to be nearer the high end as much of my driving is highway miles. Yet I consistnetly get in the 18-20 mpg range; no better than my 2002 Oldsmobile Silhouette.
    I had the dealer put in their recommended fuel additive, but it didn't help.

    Seriously, you had a Silouhette??? :lemon: just kidding...I had the Pontiac Montana version and had to replace the engine at 80k (the cars fault, not mine) and pretty much anything else that could have gone wrong with it, did.

    No really though, sorry about your mileage in the Odyssey. Maybe Honda was referring to the Imperial MPG rating and hoped no one would question it. They really need to fix that one issue, though, cuz it doesn't seem like many people are getting the published MPG in the real world.

    IIRC, our 2006 Ody with VCM had higher numbers on the sticker, but I think they assume you are going 55 mph on the highway with a horse jockey at the wheel and nothing else in or on the van, and only one gallon in the gas tank (full tank weighs almost 200 lbs). Once you go over 65 or 70, it is tough to get the VCM to shut down cylinders.

    We replaced our 2000 Silo with a 2006 Ody. Random electrical issues on the accessories forced us to get rid of the Silo after 110 K miles. Our 2006 Ody now has over 103K with only battery replacements as the maintenace issues.

    The numbers on the sticker are based on an EPA test - unfortunately, the EPA test does not replicate real world driving.

    Well if that's the case then it would certainly explain why neither of ours ever saw MPG's north of 20. On our trips we were not only driving closer to 70-75 mph (sorry, I just can't drive 55 mph) plus being fully laden with luggage and kids (4 at the time, now have 5). Honda's 3.5 V6 is a sweet engine, maybe they just just need to tune it more for low end torque and less for the VTEC howl that kicks in above 4300 rpm (fun, but doesn't seem to be compatible with the heft of the Odyssey).

    We made the same trip 2x last year in our Sienna, with just as much luggage, not to mention that my kids are getting bigger and heavier, and averaged 26 overall. This is traveling through a mix of level freeways and mountains and was achieved while spending a fair amount of time with the dial registering north of 80 mph. That was before the mandatory change to 10% Ethanol blend so we'll see how it does this time. We are taking the same trip in about 4 weeks.

    Well I must be a "horse jockey," the VCM light indicating the shutting down of the 3 aft cylinders is almost always on. I drive in the rolling hills of CT, I-95,I-395, I-84 and all the two lane roads in between, and can't remember getting less than 27 MPG per tank. We simply cruise at around the speed limits. (10% city driving.) The light goes off when accelerating and going up hill. (My wife averages 24 MPG) We have 100,000 miles + on our 2007 and the biggest maintenance item has been changing the ATF, with Honda brand, at 50k and 100k miles, and as soon as the weather is nice I'll change the Spark Plugs. (Changing the ATF fluid does involve three drains and fills per flush at about $100 for the fluid.)

    We just can't justify going 5 MPH over the limit because it just doesn't save us enough time, most of the time we drive 60 miles per trip and have always driven our cars to very high miles. 84 Malibu Wagon, V8, 256,000 miles - gave it to a friend for a $1, 00 Subaru 280,000 miles still being driven (28MPG), 01 Tundra (18 -22MPG) 180,000 miles our tow vehicle etc.

    I drive my '09 Ody 100 miles per day from NJ into NYC and back. 90% hwy, averaging about 70mph, getting 25 mpg consistantly. Would do better if I went slower, but just not possible, most cars going much faster. 24k on van now, mileage getting better as it breaks in. Was low 20s for awhile...

    I understand the speed dilemma on the NJ TP, I drive the round trip 10+ times a year from CT to Exit 4 in NJ. I'm the guy who, in the car only lanes, is always in the right hand lane and only passes one or two cars on the NJ TP per trip. I try to study the traffic and don't think I'm "holding up traffic." I am going faster than if I really was a horse jockey!

    25 MPG sound about right for 70+ MPH, nothing wrong with your car or driving habits for 70MPH. Wind resistance and friction are proportional to speed squared.
    So if it was 25 years ago and the limit was 55MPH you'd be getting almost 35 MPG! Not bad for a van.

    Are people who are getting poor mileage actually taking the amount of miles driven and dividing by the gallons of gas to fill up the tank? Don't trust the computers - Has anyone gotten GOOD mileage on an '11? Thanks.
  • My 2006 Odyssey averaged around 22 mpg from Chicago to northern Arkansas doing 80 or so. 4 passengers, luggage and two large dogs on board. The van ran better when I put Sinclair gas in it in Arkansas, but I did not track the mileage on the way back. Chicago uses that crappy additive laden ethanol gas, Sinclair in Arkansas does not. I did encounter some traffic and wind going to Ar which may have affected mileage, but the van ran fine. The ECO light was not on consistently due to speeds and wind. I took it to Wisconsin one time and she got 26 mpg for that trip only doing 65 to 70 mph.
