    How long was the trip, how fast were you going, was there a wind, was it raining? Did you spend any time at all in traffic, do you give the car lots of gas when you pass somebody, were there any stoplights, do you stop abruptly or coast to a stop, were there any hills, were there any tolls, did you use gas with some ethanol, was the a/c on, were the windows down, was anything on the roof, what is your tire pressure, do you use synthetic oil, what weight of oil do you use?

    All of these are factors have an effect on mpg, add them up and the effect is huge. To me a straight run means I don't stop even once. Just a few stops or hills make a difference. I can be 200 miles into a trip and a long steep uphill can drop my trip mpg by 1 or more.

    One of the first questions I ask people who get poor mpg is how long do your brakes usually last? Quick wear means less mpg friendly driving. For example I changed the front pads on my Integra for the first time at 185,000 miles. My Accord has 61,000 miles in two years and I can hardly tell the pads are worn at all. Anticipate stops far in advance and just glide in.

    For anybody who wants better mpg a scangauge will tell you exactly what the problem is. Another option is the new Garmins that are coming out next month. They have something called ecoroute that calculates the best route for mpg and if you plug in the EPA city and highway numbers it will take a guess at your mpg based on speed, stops etc. It will also grade your driving based on how smoothly you stop and start etc. I highly recommend this. If you have a current nuvi 2x5 or 7x5 it can be upgraded to the new software.

    BTW - I forgot to add my latest lifetime mpg on my last post. Now at 33.80 mpg

    >"All of these are factors have an effect on mpg, add them up and the effect is huge. "

    I agree 100% ! :)

    Every item in your first paragraph are "Right On". I believe the brakes are the # 1 enemy of MPG in local driving. The more they are used, and the harder they are used, the worse the mileage. Of course, the throttle and how it is used are also great contributors to poor mileage.

    On the road the throttle and speed are # 1.

    We don't own an Accord, yet. But we do own an 03 CR-V. It is heavier and pushes a lot more air than the more aerodynamic Accord. Engine is the same tried and proven 2.4, and the tranny is a 4 speed auto. I would expect that the 5 speed auto would get a bit better mileage. With me driving locally, 25 mpg is fairly normal. On the road, 30-31 mpg is fairly routine. My wife gets 3-4 mpg less, across the board.

    The CR-V is her car. At 40K +miles, the front brakes and all 4 tires needed replacing. She is not a "Hard" or fast driver, but she tends to stop rather than coast to traffic lights and stop signs. From a stop, the tranny shifts at closer to 3000 rpm,for each gear, and she rides a bit close to the cars in front of her, requiring little braking on her part, but more on and off the throttle.

    She likes to go a bit faster, on the road, than I do. So mpg is less.

    Also agree about the "Scan Gauge". Wonderful tool. :)

    Yesterday I filled up at $2.26 :(, but my calculation showed 26.3 or something above 26, not sure of the exact number, and I wasn't exactly kind 100% of the time. There was some fast acceleration and speeding, but this is how I've been all year so I think it's good. I take this to mean that summer blend has hit our region, upper midwest, again and we'll all start to see an improvement soon. :) My rolling average, since March 2, 2008 is currently 25.289. I've gone 14828 miles on 586.335 gallons. If anything the combined rating, for me is spot on accurate. It does do a good job of evening out the differences that are inevitable from tank to tank. Overall, with my combined average, over the course of a year and a couple of months, being as close to sticker as it is, I'm happy.

    In the most recent 900 miles, my trip computer says we've averaged 26.7 mpg.

    This is on our 2008 EXL navi 4 cylinder 5 mt.

    About 70% city and 30% hwy.

    Not bad, imho.

    Course, it's spring, and so we're not using the ac much. In summer I assume it will go down a couple of mpg.

    Very pleased with my mileage. Currently averaging 24.632 on my first 5 fillups of the new car. My last fillup just registered 27mpg. Most of my driving is a 50/50 split. I'm more than happy with the power this car has and getting this kinda of mileage. I'm higher than the combined EPA which is great! I'm pretty confident I can get above 30mpg on a pure hwy trip. Most of my driving is in the ECO mode which helps. I'm getting more used to VCM and who knows how much of a difference it makes, but the mileage is going great for a new car. I expect it to get marginally better as it breaks in.

    25 mpg on my 02 V6 Accord. 90/10 highway. Add 2.5 mpg for the ethanol and 1.5 for the Goodyear Comfort treads I'm running and that's about max for my model year. 98k miles and runs like new.

    .....calc'd my May 2009 fuel numbers just for grins: 1060.8 miles, 37.193 gallons. 4/24 - 5/24. About 70/30 Hwy/City around our state capital. Works out to 28.5 MPG

    I try to get into those top two overdrive gears ('05 6M coupe) with all possible haste. And y'all can see the resultant...................

    all the best on this Memorial Day weekend, ez.......(USNR)
  • blufz1blufz1 Posts: 2,045
    Got 2 fewer gears,an auto,and the less efficient 02 engine. I'm turning 2000 rpms at 60;what are you turning in 6th? Stay safe.
  • ezshift5ezshift5 West coastPosts: 854
    ...........is about (per CD): circa 57; go with Road and Track, then right at 60. I tach between 65 - 66 at 2200. CU later (alligator).

    best, ez......... :)

    '08 Accord Sedan I4 EX-L from Roanoke Rapids, NC to Greenville, SC and back to Concord, NC approx. 90/10 highway: 30.7 MPG!!
  • """ Add 2.5 mpg for the ethanol and 1.5 for the Goodyear"""

    Do you mean subtract 2.5 for the ethanol - ? It is my understanding that Ethanol is 30% less efficient than traditional gasoline.

    One more tank and this one was a record for distance. 647.7 miles.

    This was over 8 days including all my running around town for that time, and included two trips. One of about 125 miles round trip and the other about 430 miles. The second leg of the 430 mile trip was from Bismarck to central SD and I averaged 47.0 for the entire 220 mile day (a few miles of city as well). My average speed on the trips was about 60 mph (mostly two lane rural roads) and I did not use AC. Temp was about 68 to 74.

    Overall. 647.7 miles 15.60 gallons = 41.5 mpg The fuel light came on at 608 miles. I also think I overfilled a little as the scangauge indicated 42.4 for the tank and I put in 1.2 gallons after the pump clicked the first time on the slowest fill setting.

    Lifetime is gong to crack 34 for the first time real soon. It is 33.96 right now.
    10 tank rolling average is at 36.9 mpg

    2007 I4 SE MT 40 psi and Mobil 1 0w-20, 62,000 miles.

    E85 is; E10 (which most of us are using now) isn't so drastic.
  • ezshift5ezshift5 West coastPosts: 854
    You - Senor - are as good with a 4-cyl as YT with the J30-A4 (perhaps better).

    Seriously, great job: 47 mpg is advanced technology territory these days. Few can (or deign to) accomplish 45+ MPG.

    In summation (after recently Road Testing a 2008 Infiniti G37 6M coupe "on sale" for six grand off MSRP):

    Leaving the dealership with 'Let me alone to think about this test drive" - - - - I headed south - two lane, deserted country road - straight as a arrow. The J30-A4 rarely dissapoints. This time was no exception. Add the 40 MPG potential: The AV6 6M remains for now.

    Hang in there..........best, ez....
  • dudleyrdudleyr Posts: 3,436
    Ironic, but in SD where we produce much of the ethanol and have E10 mandated for midgrade 89 octane (and one of the highest percentages of stations with E85), we have no ethanol in our 87 octane regular gas even in winter. A side effect is that the midgrade is always cheaper than the regular. I buy the regular without ethanol for the better mpg.
  • dudleyrdudleyr Posts: 3,436
    We sure make the most of the MT - still wish I had 6MT though.

    That new Camry I4 with a 6MT throws a little salt in the wound.
  • ezshift5ezshift5 West coastPosts: 854
    ......Camry I-4 6M def appeals to my fuel economy genes. I'm willing to bet a couple of belts of Crown Royal that the car is only available with an automatic transmission in California. Looks like my Accord 6M coupe has REALLY found a home!!

    all the best, ez....
  • blufz1blufz1 Posts: 2,045
    Actually,I was adding it to my mileage to make it comparable to those who don't run ethanol. I run ethanol in my car.
  • tankbeanstankbeans Posts: 585
    Thought I'd update...My year long-term average, since March 08, is still hovering above 25mpg. My yearly average since January is just above 22 and my seasonal average, since the beginning of April, is around 24. I'm thinking I took a minor hit when I bought tires, but can't be sure because my commuting distance also changed recently. The nice part about that, though, is that if I leave at the right time I can time it so I squeeze through most of the lights on the way to work. There are about 15 lights and I usually only have to stop for 3 of them.

    My last tank was 25.3. Overall still very impressed considering the size of the vehicle and the way that I drive.

    62,9xx miles and counting.
  • catmikecatmike Posts: 35
    For almost a 18 months, I've been tooling around trying to average 25 mpg - no long trips, just neighborhood driving. My hope for trip mileage in this car was 28 mpg. However our mpg was: one 28 mpg tank and two 31.5 tanks and two 39 mpg tanks. Hot, humid weather required the AC on 100% of the time. Car was overloaded with correct tire pressure.

    The EXL 4 drive was smooth - drove like an upsale touring model. And for those that haven't noticed the benefits of Grade Logic - drive the Smokey Mtn's - it's a fantastic feature.

    This is the second time I have recorded this level in 18 months of ownership. Details: 2007 EX-L, 4cyl, auto, 40K total miles, original tires at 2psi over recommended, Mobil 1 synthetic oil, AMSOIL microfiber air filter.

    All highway/4 passengers/trunk full of luggage - 100 miles at 60-65 mph rolling hills...340 miles of interstate at 80 mph all with AC on. 440 miles/11.2 gal (regular)

    I typically get 28-29 on my daily 30 mile DC commute. :shades:

    I just filled up the first half tank of gas on my new 09 Coupe, I4. The mpg calculated out to be 25.6mpg. The 285 miles were the first 285 miles on the car and about 60% hwy and 40% city.

    I'm not quite impressed with the mpg; I am used to crushing the EPA estimates. Even with my V6 Double Cab Tacoma I was getting 22ish mpg. My driving habits are fairly light on the pedal, but maybe I was a little eager to test out my car on the first few miles.

    So my question is, have people noticed an increase in mpg once the engine is "broken in" per se?

    Thanks!

    I didn't notice any change on my 06 EX-L I4 but many people have posted that they get better mileage as the engine gets broken in. Besides that, you really can't judge a half tank of gas, especially the first one. Did you fill it or did the dealer? They aren't always as accurate as you might be.

    Keep us updated.
  • cpboy99cpboy99 Posts: 8
    Thanks Tallman1. The dealer filled the tank. Will post again after about 4-5 tanks.
  • catmikecatmike Posts: 35
    As "thegraduate" told me 18 months ago my 08' EXL I4 would break-in over some 12,000 miles and the mileage would improve. So, 15,000 miles later I have to say that "thegraduate" was right! Mostly city/country here - not many hwy miles, on a recent trip to TN: 28 mpg on one tank, two tanks at 35 mpg and two at 39 mpg. Brand spanking new my first tank was 17 mpg but of course the dealer filled the tank, lol.

    Give it time and you'll be busting charts. :) and as always thanks to "thegraduate".
  • cpboy99cpboy99 Posts: 8
    That is the best news I've heard all day! Woohoo :)
  • tallman1tallman1 Posts: 1,874
    Yeah, as I said, most folks seem to get better mileage as time goes on. Mine has been stellar from the start. I've only had a handful of tanks that were below 30 (only two were below 29) and my lowest ever was 28.0. Highest ever was 41.7. Not bad after 72k miles. :shades:

    Congrats! That's great for such a big car with 190hp.

    And, what can I say, I like being told I'm right once in awhile. :)

    Enjoy the car!
