There is not enough information to provide an educated SWAG. Specifically you need to put factors/variables into contexts. Shooting from the hip, maybe, albeit slightly.

3rd tank full by ruking1

The figures are in and the 3rd tank full is 36 mpg.
 
So as a range, new tires have crashed (mine) mpg 1.5 to 2 mpg per gal: old tires 38-40 mpg new tires 36-38.5. Again far from correlated but one anecdotal data point.
 
Old tires: Dunlop SP20 FE, UTOQ 320, New tires: Toyo 800 Ultra.UTOQ 700. 74,300 miles is the number to beat!

Correction: the 3rd tank full was 37 mpg.

New Civic 08 coupe - 21 mpg in city by vitakh

About a month ago I have bought a new Civic 08 coupe. It has 500 miles now and makes less than 21 mpg in city. I am trying to drive stingy, minimizing the break usage.
 
Is this millage low enough to complain to the dealer? What may be the problem?

So while I would not discourage you from bringing your car in (especially) during the customer satisfaction (1 year /12,000 miles typical) warranty period; I would further swag the dealer will indicate nothing wrong with your vehicle. If you do decide to bring it in for that reason and/or other things, please post/repost.
 
Honda Civics are (designed) optimized for a min of one hour operation, 45-75 mph situations. On the EXTREME up side, hypermilers can get in the high 50's mpg.
 
Given your snapshot (21 mpg) and realistically without a lot of information, I would SWAG you operate in the worst city conditions (for a city environment) and are driving absolutely the HARDEST mileage for ANY car, but specifically a Honda Civic.
 
So for example, if you look at the survey posted, MSG #1416 and the/YOUR new car sticker's SMALL PRINT (right under or near the posting for EPA City and Highway ratings) you will probably see that (21 mpg) is within the range, albeit a very low percentage of folks reporting that range of mpg.
 
If you do a tremendous amount of idling,stop/go was a hybrid one of the considerations? (i.e., Civic hybrid, Prius,)

ruking, thank you.
 
Actually my driving is not strictly city, but include some free-way roads.
 
I guess, the millage may improve after 1000 miles. Also I may try to use another gas station (I use Gulf with cheap gas).
 
I'll let you know if talk to the dealer.

Indeed it should somewhat. If nothing in the driver's behavior and/or conditions change, I would not reasonably expect much more than 1/2 mph more.

09 Civic mpg by cherubja

I recently purchased an 09 Civic EXL and have been getting less than 30 mpg average. I drive about 60/40 city/highway. I am very easy on the accelerator, and I do not leave the car idling, not using a/c either. The car has about 500 miles, will the fuel consumption improve? I used to get over 30mpg average in my old Saturn, I figured this car would be better...

While we have (from new) put down the mpg data ( 04 Civic), (baseline measures mainly- we did not endeavor to get what we actually got and documented) I would not even worry about till app 10,000 miles.
 
Up untill then, you have SO much going on, i.e.:
 
1. up to 500 miles less than 55 mph tire break in new tires can suck -1-4 mpg
2. choice of whatever psi can make 1-2 mp difference
3. proper engine break in (who really knows mpg)
4. brake pads bed in (want oems to least INXS of 100,000 miles)
5. component parts getting used to each other, suspension, transmission, etc.
6. even stuff as mundane as getting used to driving the car: that some to all the variables might become moot at that mileage. This can make 1-6 mpg differences.
7. non standard driving due to new pony rides
8. less/more than optimized conditions
9. ETC., ETC.
 
So as a anecdotal data point we started off getting a range of 36-38 mpg. Fast forward to currently: get between 38-42 mpg in a normal everyday 54 miles R/T commute (.75 to 1.5 hours) . I am also aware a LARGE majority of folks (94% or so) report getting less ! This commute seems to be what the Honda Civic was optimized for. We are currently in the 77,000 miles range. OCI's of 20,000 miles with Mobil One 5w20, 0w20 oil and 20,000 miles (per owners manual, shop manual, internet Honda recommendations ) oil filter changes. Oil consumption is between 1/4 to 1/2 quart of oil in 20,000 miles. We employ no real fuel miser techniques other than not getting in accidents in a rolling parking lot commute.

My '08 LX Sedan AT did improve after the first couple of tanks. My commute is much like Ruking about 60 miles each way and driving normally I was getting about 38MPG.
One thing I just noticed is that my mileage just dipped as the weather here in the Boston area is dropping below freezing.
