    I got over 32 mpg on my weekly trip to the eastern part of WA state. Lots of rain and huge puddles of standing water on the mountain pass, which also made speeding up and slowing down a part of the trip. Pretty windy on some portions and there was some city driving as well.

    This is pretty good for the colder weather and all that rain. I've been over 40 mpg with slower speeds and much better weather. The trip computer showed over 37 mpg on the return trip but that will change by the time I fill up.

    My 2004 V6 A/T Accord EX Coupe averages 20 to 22 mpg on a day-to-day basis with local commuting and some highway. On long flat highway trips with not much interfering traffic I can get 30 to 31 mpg keeping it under 75 mph.

    My wife's 2008 I4 A/T Accord EX-L Sedan hasn't had a complete fillup yet, so no statistics. I'll know in a few days.
  • My 2003 Accord LX I4 is averaging about 27 mpg with about half city/half highway and a very short commute, 6 miles each way all highway(save the mile it takes me to get to the highway). On a long trip 300 miles I got around 35. I had a 95 EX I4 and that averaged about 23 under the same conditions.

    robertsmx -

    I have to say, thegraduate and blane are correct on this issue, are you are just plain wrong.

    "When you fill up, how do you know the tank has just the amount of fuel it needed? Did the nozzle stop too early? Or, too late?"

    This initial statement is correct. The particular fuel pump could shut off earlier or later than your last fillup, which could effect your MPG calculation. But this only applies when you are FILLING UP your tank, when the nozzle senses the tank is filled.

    When you are only getting small increments of fuel (partial fillups), there is no possibility of the pump shutting off too early or too late. It shuts off when you want it to. So if you pump 2 gallons of gas, you get 2 gallons of gas.

    "So, after x miles, you might calculate from 13.1 gallon (one fillup), or from 14.3 gallons (multiple fillups)."

    This doesn't make sense. You wouldn't be making "multiple fillups", you would be making multiple partial fillups, which would not be effected by the pump shutting off too early or too late.

    "Almost always you will find that computation based on multiple small fill ups will result in poorer fuel economy than would on a full tank fill up. Try it. I have."

    I think understand...you are confused as to what is being discussed. They are not computing MPG based on topping off the tank with "multiple small fillups". They are only completely filling the tank one time.

    What you said mattgg1 is what I wanted to say, you just beat me to it.

    Something else to mention is that if a pump reads wrong, say, it shows an extra .1 gallon pumped for every 10, that difference will be smaller if you only pump one gallon (meaning it would be off by .01). It's not a difference of .1 with every addition of fuel, the amount that the pump is "off" will correlate to the amount of gas pumped. The "click" issue isn't an issue at all until you FILL the tank.
  • MPG = 22.06
    60% city (stop n go)
    40% highway

    Initially I was disappointed, but when I considered the following I guess it wasn't too bad.

    1. 1st tank
    2. I'm constantly changing speeds for engine break-in reasons ie. no cruise.
    3. winter gas
    4. Temp. has been in the 20's
    5. I swapped the oem Michelin's for the Bridgestone Turanza Serenity's. Softer
    rubber - I think. Of course I don't know how much softer any rubber is at 20F.

    Also, the "trip computer" on the Navi said 22.1mph when I filled up. I was pretty impressed with it's accuracy.

    ......seems right from here. That VCM must be treating you right. Hope you post trip (freeway) numbers when feasible.

    best, ez....
  • robertsmxrobertsmx Posts: 5,525
    My emphasis is on precision. If you fill up 1.04 gallons everytime but record it as 1.0 gallon, and do so 12 times. Would it make a difference to consider that 0.04 gallon? Well, it would seem more logical to say the fill up was 1 gallon, and twelve times is 15 gallons, and that the car covered 375 miles on it for 25 mpg.

    In reality, the person might have actually filled 15.6 gallons for 24.03 mpg. It is easy to ignore smaller numbers. If precision is maintained, then accuracy will simply depend on precision of the gas pump.

    Hmmm... I have just over 3500 on the odometer. Filled up the tank after 320 miles of mostly highway driving with maybe 25% short-distance, in town driving. My fuel economy dropped to 23.9mpg.

    I guess I just have lots of things working against me . . high elevation (6000' average), 85 octane gas with 10% ethanol, cold temps (30 degrees), winter gasoline and fast highway speeds (70-85mph). But, as I've said on this post before, I don't think my I4 98 MT Accord ever got that low . . .
  • robertsmxrobertsmx Posts: 5,525
    fast highway speeds (70-85mph).

    Consider wind and hills as well, and the very fact that is highlighted above. If you were getting better under identical condition in a 1998, then you might have a point of concern. Otherwise, it is newness (and getting used to a new car with AT versus being used to old with MT), and/or something else working against you.

    Which Honda Accord generation is considered to be more fuel-efficient, 2003-2007 or 2008+?
  • thegraduatethegraduate Posts: 9,731
    The 4-cyl Accords have the same basic economy in each generation, both 7 and 8. The V6s are improved for 2008.

    3.5 tanks of gas and still seeing a steady 25.X MPG with my 08 LX 5 spd.

    I did do a half tank with a mostly highway trip (filling up before I left and when I returned) and came up with a shade over 27 so I believe she'll do better over time (and once winter blend gas and snow tires go away in the spring.)

    It's been my experience that that combination of factors in the winter looses me an average of 2 MPG. My Mazda6 would do a steady 24ish in summer, 22-23 in winter. The Protege5 did a solid 30 all summer long, in winter it dripped to 28ish.

    My sons always rev engines a lot @ 3000+ RPM. I only need 2000- 2500 RPM on my V6 most of the time. Do not brake abruptly, Do not accelerate too hard. Imagine you have an egg under the gas pedal and imaginarily try not to brake that egg.

    I always achieve MPG which exceeds sticker's MPG. Honda is very good at achieving good MPG that is better than sticker's MPG figures. Good luck guys & gals.
  • I have approximately 700 miles on this car so far- and my most recent tank of fuel proved dismal in terms of fuel economy.... 19.68 MPG....

    The tank prior I got about 22 MPG... I imagine the colder weather is playing a role in the drop- but certainly hope the mpg improves this spring -

    Does anyone know when the engine is said to be broken in ? I suspect this will help fuel economy as well...

    Quick questions: In your previous car (assuming there was one), what was the vehicle, and what mileage did you get in the same conditions? What are your conditions (route type, traffic/hills/idling/warming up the car, etc)?
  • Can anyone give me some advice on sedan leather interior? Which looks the best?
    I am strongly considering the polished metal with black interior? However that white diamond pearl looks stylish with the ivory leather ? I want an upscale look but actually I am a little concerned about the light color? I am a family person with kids and a dog that will be riding often . Someone help me out. I have already made my mind up on the v-6. By the way what does anyone think of the gray it seems a little light in the pictures. It seems like the black interior goes better with the polished metal color.

    Try some of the other forums. This one is dedicated to fuel economy of the Accord. Here is a forum dedicated to the colors of the Accord. Honda Accord Colors Happy Hondaing! :)
  • My previous car was a 2003 Accord sedan- LX automatic - 4 cylinder... Under similar conditions, I was getting 24 mpg- city/highway combo/ few hills-- and normally little or no idle time..
  • blufz1blufz1 Posts: 2,045
    Your mileage will not be better than you previously got on the '03. It's a bigger/heavier car.

    I haven't posted an update in awhile. For those who don't know, this is a 2006 Honda Accord EX 4-cyl 5AT, with 26,700 miles. 40% oil life remaining.

    406.1 miles
    13.085 gal @ $2.869/g = $37.54 of Texaco Regular
    _______________
    31.035 MPG

    This tank had about 160 miles pure highway on it, with the rest being my in-town/suburban commuting that includes about 40hwy/60city (city meaning lots of traffic lights, hills).

    For the record, the light came on about 1/2 a mile from the station, meaning there was at least 4 gallons left in the 17.1 gallon tank when the light came on.
  • I am so sorry I didn't mean to post my question here. Didn't realize it until this morning.

    It's ok. I hope you found what you were looking for in the other forum!

    I found the hack by searching the forums can't remember if it was on here first or vtec. I did not discover it though, but somebody at Honda must have put it out there. I know Mazda has something similar with activating the trip computer on lower end vehicles.

    tankbeans
    as far as remembering settings goes. If you have the a/c turned off and then turn off the car, you don't have to turn the a/c off again once you restart the car. If the car is running and you switch from one mode to another (defog to ft/defog) the a/c light will come on and need to be turned off again.

    Now that it is winter (1 degree out this morning) the a/c should never come on if the temp is below freezing.

    Speaking of winter some recent driving in very cold temperatures has yielded my worst highway mpg to date by a large margin. Very cold temps have a huge effect on mpg.

    I had a tank with 470 miles that only gave me 30.4 mpg. This was 220 miles highway 30 miles stop and go then 220 miles highway return trip. My trip on the way there was at 65 mph for the first 30 miles with completely white roads and temps of about 20. The next 190 miles I averaged about 65-70 with precipitation the entire way ranging from sleet to snow to freezing rain. The temp was below 28 the entire trip. And yes I have 4 snow tires (michelin x-ice) so I was not driving too fast for conditions.

    The roads were better on the return trip, and I averaged about 70 mph, but the temps were much colder - low single digits. My scangauge showed only 29.8 on that leg. First highway leg below 30 - the horror.

    Nice looking car grad - looks just like mine.
  • thegraduatethegraduate Posts: 9,731
    Dudley, is yours an EX cloth too? I was thinking you had an SE for some reason. They do look identical though!
  • dudleyrdudleyr Posts: 3,427
    Yes I have an SE, but on the outside it looks just like the EX cloth - unless you look from above and see the sunroof.

    Same color and same wheels. Although right now mine is kinda white looking with all the salt.
  • Salt is a big bummer. I guess I did the hack wrong, oh well. I'm not about to complain over small things. The next time my car gets washed will probably be in April. No point right now. It'll just get dirty within about 5 seconds anyway.

    Grad, your car does look great have fun with it. Oh wait you already do ;) . Anywho, I'm just going to learn to switch off the defrost once it's done it's job for fear of messing up the computer by continuing to try the hack, too expensive to have it reset at the dealer I would imagine.
  • thegraduatethegraduate Posts: 9,731
    To reset, I would think simply disconnecting and reconnecting the battery would suffice, but do whatever you think is best for you! :)
  • waltchanwaltchan Posts: 123
    Well, I now get over 40+ MPG on highway. I only drive 55 miles max since new. Is it possible to get 50 MPG if I continue to drive only 55 MPH max for the next 10,000 miles?
