I assume that a Scangauge could quickly confirm the warm-up time needed to get peak efficiency. I thought now during the summer months that getting the engine up to a temperature for good efficiency happens quite quickly, particularly at highway speeds. My commute is close to 30 miles each way and I'm usually on the highway within minutes of starting out.
Yes, too bad that the MT isn't geared taller. At least the difference with the AT isn't so great as to show up in the highway EPA numbers like on the Civic.
Dudley, I do happen to be planning a drive up to Maine shortly, but not for lobster. I don't care for the things.
blufz - I think you are due for a nice leisurely road trip to get in touch with your inner hypermiler.
My family rode with me to Gulf Shores from Birmingham. Had some traffic (we plodded along through Birmingham instead of hopping right on the interstate). Used A/C the entire time, and averaged about 75 MPH (not consistent though, my max speed according to my Garmin Streetpilot c330 was 85MPH). When filling up, after 263.9 miles, the car took 7.4 gallons, which equated to about 35.7 MPG.
Conditions:
3 people in car (who weigh about 600 lbs combined), plus their luggage for 8 days (the trunk was full). 85 degrees. 100% oil life.
Forgot about the V-6 part. Now I remember - it is for the boat. Not gonna get near 40 with a boat in tow.
Doesn't seem low at all to me.
Good luck.
I just got back from a 520 mile trip (twice this month - ugh). Took the speed up a little to 67 mph on cruise control. Mpg for the entire trip was 38.3. The A/C was on the whole time - it was 108 degrees yesterday, so no messing around without the A/C. Compared to my trip last week, I added A/C and 7 mph and I dropped 5.5 mpg.

I need to go again in two weeks - may try another speed. I think I will also do a few runs on a flat stretch at different speeds to see what that does. Kinda curious about mpg at 100 mph now - don't think I will take it that far though.
If he works at a hospital and say he works in something like triage and a cop is wounded, yeah I think if he helps out they won't bother him after that. I got busted driving 75mph in a 25mph The entire town is 25mph and the road is as straight as a dragstrip and at almost 3am I had to rush my previous wife to the hospital her water broke early due to complications. It was a serious thing that I won't get into here but not a single other car on the road. First time a cop ever pointed a gun at me for speeding and in front of the hospital emergency room to boot.
She had to go in alone and finally the cop put away the gun and kept going on and on and I told him, you know what? write me a ticket but I'm going in with my wife and I walked into the hospital. turns out they needed a lot of emergency stuff just to keep her alive, another hour and she would have died. They stabilized her and she had to be taken over 2 hours away by ambulance as she was in rough shape and they weren't equipped to deal with it. The cop never did write me up that ticket but in my eyes at 3am under those circumstances and considering that entire town is a huge speed trap I'd have fought the ticket.
Oh and for the record during the day 35-40mph would be safe on that road but not faster because of traffic and stores, it's basically a long strip of stores that all close about 9pm. Nothing is open after 10pm, at least not back then. During the day no way would I have gone that fast but at 3am under dire circumstances yes I would and I'd do it again under similar circumstances.
This from the same town that tried to give me a ticket for going 25mph in a school zone in july at 2am on a sunday! because the automatic lights were flashing.
I really appreciate where I live now, no speed limits, no cops outside the dense areas where you can't speed anyway because of all the traffic. No traffic lights, or patrol cars and somehow most people survive somehow without speed cameras and the like.
You can just pay the ticket if you feel like it's worth it.
July 2007 (6/25/07 - 7/25/07) 87 octane.....
1324 miles on 48.175 gallons. 27.48 MPG.
5 tank-ups. Range 25.7 (hi a/c use) to 29.6 (Interstate use)
2005 AV6 6M coupe;36k;dino;32F/30R. (..ez sends..)
Here are some numbers to date.
Overal average has slowly creeped up to 33.5 mpg (377.5 gallons 12653 miles)
I have been doing a rolling average of my most recent 10 tanks (miles driven for last 10 tanks divided by gallons used for last 10 tanks) This gives me a nice way to show trends and level out single tank inconsistancies. Below is a list of these rolling averages. There is a definate trend towards better mpg as the vehicle breaks in. It will probably go down again with the approach of winter with a small spike up for fall when it is cool enough for no a/c, but warm enough for good mpg.
The 30.7 is the average of my first 10 tanks and each subsequent number is the average for the most recent 10 tanks at the time.
30.7, 30.7, 29.8, 31.2, 31.5, 31.7, 31.3, 32.0 32.3, 33.0, 33.4, 33.7, 34.3, 33.8, 34.0, 34.3, 34.2, 34.6, 34.5, 35.4, 34.9, 35.1, 34.4, 34.4, 34.2, 34.6, 35.8
So far my best tank was 41.5 calculated (41.4 scangauge). This was 556 miles on 13.41 gallons. Within that tank was a 510 mile stretch of 43.8 mpg (60 mph). The rest was 46 miles of stop and go in town which brought down the number to 41.5 mpg.
Happy with the numbers, of course I still want more - diesel Accord soon I hope.

If so, you are doing pretty good if you drive in a "spirited" fashion, not "pathetic" at all.
Automatic, or manual?
fill it. take it on the HWY for a few good 250-300Mi trips at 65 steady. compute the fuel economy the manual way. average the results.
you may be right in the pipe.
Btw, can someone drive an auto in a spirited manner?
But yeah, with a daily average commute speed of 75-80mph and the A/C turned on full blast, 25MPG seems pretty good for an I4.
Btw, can someone drive an auto in a spirited manner? Manual all the way!
Atlanta highway isn't "highway" as many people know it. I live in Birmingham and have been in ATL traffic several times. Its 80+ MPH or dead, with lots of speeding up and slowing down.
Thought I'd update. I just traded in my 95 Accord EX I4 which was averaging 23 mpg, short trips, mostly in town, not a lot of freeway, for a 2003 Accord LX coupe I4. I just did my first mileage calculation and came up with 26.1. That wasn't very accurate because it was ranging two tanks. I had to add a little before I could fill it completely.
I've got a '96 LX Accord which averages 27 MPG, and a 2006 Accord EX that averages 29 MPG.
The new cars have higher EPA ratings too, so this seems right.
I love the extra power AND economy that comes with the new Accords over my old one (my LX is only 130 hp - your EX at least had VTEC w/145 hp!).
Anyway, overall tank was 31+. backing out the around town miles at my normal +/- 25mpg, that leaves the trip part at ~35. Not too shabby, given the conditions.
A bit of creeping in the parking lot, than stop and go getting out of the city. About 200 real highway miles, ranging from about 67-75 usually, occassionally creeping a bit faster. Lots of "smokies" so that kept the speed down.
SO, IMO, 35 ain't bad for a blast up the NJ turnpike and into NYC.
2005 EX-L 5 speed 4 cyl, 2 people, air on most of the way.
I'm starting to wonder if I took a Graduate style trip if I couldn't sneak up on 40 mpg after all!

In fact, I am heading for the beach Friday with a guy friend of mine, and will have to go 70 MPH. There is a major crackdown on speed this week, and troopers are pulling no punches in Alabama, ticketing people over for 1 MPH over, not using a signal when changing lanes, and tailgating, things that typically go without reprimand.
Here's the story, on our local affiliate NBC 13.
Maybe, at 70 MPH, I'll get back to 40 MPG? The only hindrances will be weight (my buddy is a BIG guy) and temperature. Our highs have been around 103-105 degrees in central Alabama, surpassing record highs day after day.
So, with 70 MPH, 105 degrees, and 450 pounds on board, I'm hoping for at least 37 MPG.
The car had 15 miles on it when I picked it up. I was able to make it back non-stop on one tank. I topped the tank off before I left to get an accurate mpg reading as it was not quite full. A/C was on 100% of the time. I tried to keep the speed varied between 60 mph and 75 mph, changing it up every 20 miles or so for the break in.
Stats:
505 miles
14.02 gallons
Average speed 67 MPH (calculated by GPS)
85% Interstate / 15% State 2-lane Highway
36 MPG
I have a question that I would guess somebody might know. Do the 2003 LX I4 have 5 gears or 4. I read the manual and it said that it did. Then I looked on some web sites and they said the 5 speed auto was optional. It does seem to have one more shift going.
Just curious. I do notice that it revs lower about 2500 at 80 than my old car did about 3000.
You'll notice on the highway that you can call for either one downshift OR two, depending on how hard you hit the gas. Makes things easier than the big jerky 4-3 downshift of our '95/'96 Accords at 75 MPH.
The automatic Accord 4-cylinder runs 1,000 RPM per 30 MPH in fifth gear, so at 75 MPH you are at 2,500 RPM.
Unless you know someone wanting to pay $10k for a car with 175k miles
I bought a used 97 Accord LX (non VTEC) a year ago and am not too happy with the mileage. I consistently get a mileage of 23-24 mpg in mixed driving - mostly on short trips on the highway though (10-15 miles). Obviously, something is off. Any suggestions on what I can try? I have changed the PCV valve, used fuel injector cleaner and used synthetic enginer oil (Pennzoil) to no avail.
One other thing, the car appears sluggish and seems to lack power. Any suggestions on what to try are greatly welcomed.
I know the car should do better than this. I owned a 82 accord a while back and that used to give me 32-33 mpg. So something is definitely amiss here.
Did you drive your '82 as fast (the speed limit may have been lower then)? Remember the '82 had a 1.8 liter engine. Was the '82 a stick or an automatic?
These are all factors - the more info the better.
Also, it seems on par with the revised EPA estimates. If you go to www.fueleconomy.gov you should be able to get a little more information about what you should be expecting.
At first I thought that I was getting sub-par mileage but then I went out there and I found that my mileage was about average.
Before this becomes too long winded, how often do you use A/C in your car and also I think the LX came in a V6. Do you have a V6 or an I4?
I can guarantee that you will get a lot of the same questions from everybody out here. These were the questions that I always got whenever I asked a question regarding mileage.
Good luck and have fun with your car.
Burbank to LV calculated 36.2.......even with a/c from Baker eastward.
...and this is the V-6.
best, ez..
Wait 10,000 miles.
My guess is that you have a lot of short trips and that the engine isn't fully warmed up. Either that or you have a pretty heavy foot. If you are driving at a fairly moderate speed, even with the AC, you should be getting way above 25 on the highway.
With only 1000 miles, you couldn't have taken a very long highway trip to accurately figure mileage. Heck, 1000 miles is barely over 2 full tanks in my car.... and I can get 500 miles out of a tank if I only drive on the highway. :shades:
I bought the car in Chicago and it was 250 miles home. The car had 2 miles on it when we picked it up. We got about 25 miles on the way home. I know the car has to be broken in though 10,000 miles seems like a long way away when others are getting 30 right away.
Who knows. If it doesn't get better soon I am taking it in. I love Honda. Well I am frustrated right now though.
