Hey guys, i just bought a civic less than 4 months ago. Ive been noticing that my gas mileage ranges from 28-32 MPG. I have an EX coupe automatic model.

I just want to know wat everyone else is getting for his/her MPG. I thought I'll get more MPG out of my civic. Thanks guys!

I get about 32-34 but i have 100+ pounds in my trunk. and BTW i drive an 05 Ex coupe auto with a k&N typhoon intake. I got an extra few MPG out of the intake. Sounds nice too.

So far Simon, since I have owned my civic (bought it June 7th, 2005), I have been getting an between 35 to 39 with city driving (stop and go), and 40 to 43 with mainly highway miles (constant speeds about 70 to 80).

I have a 5 spd manual 2002 Civic EX coupe, so I don't know if an Automatic will get the same kind of MPG as most manuals do.

My first tank of gas was the worst (33 mpg), while I was getting reacquainted with driving a stick (after 15 or so years of not driving stick).

What are your driving habits? Lot of short trips (under 15 miles RT), with mainly stop and go traffic? Alot of cruising? Got lead foot disease? Live in a hilly area?

I do more highway driving than anything else, so it shouldn't come as a surprise that I average ~41mpg.

01 ex 5sp coupe. 40 in the city going stop and go, and if i cruise its around 50. 40+ on the highway, cruising at 80. i don't use the a/c unless the winshield fogs up. i bought the car in february and put iridium plugs in it, i noticed a difference in gas mileage cause it got better. 65k on motor. all else is stock

28-35 depending on how i drive with i/h/e, 18's and a/c running almost 24/7

I get about 36 mpg overall with mostly city in the summer and mostly highway in the fall. 04 5speed EX 22k miles. System and ebay intake and running on the 2nd tank using FP60 and the engine runs smoother and seems to be getting about an extra 2-3 mpg. SEEMS

25-30mpg

There are so many factors that determine mpg:
-temperature
-style of driving
-transmission
-cargo
-rim size
-type of driving city vs highway, and everything in between
-windows down over 50mph
-ac on, which is actually quite minor compared to windows being down
-elevation
-tire pressure
-dirty/low oil
-up hill vs down hill driving
-mods
-dirty car-really minor
-unbalanced tires
-out of alignment
- did i miss anything???

oh yeah my mileage verys so damn much cause alot of times i am sitting in parking lot with ac on, driving near redline, but sometimes i like to drive like granny.
I would say 25-40LOL

man, my car must get really shitty milage then. was drivin for awhile with a filthy car, low air pressure, out of alignment, un balanced and windows ALWAYS open over 50. lol.

28-35 mpg from mixed city and highway with occasional a/c

 
Rep Power: 282

Filthy car prob does not do much, im talking muddy, and that still prob not that much.
Yeah but you would be suprised about how much low tire pressure, unbalanced tires and open windows wil decreae your mpg. Also a/c is realy not that bad, i hate when people will not turn theirs on because they are low on gas, it really ticks me off.

i get about 35mpg in the city when im driving it pretty hard, about 40ish on the highway. this is with a totally stripped out trunk and almost no extra weight in the passenger compartment, besides myself.

28-34mpg boosting around 9psi daily .....depending on how hard i drive

I went 346 miles from a full tank. Then I ran out of gas. 04 dx/vp .

Thats like 26MPG!

Tire pressure is good. Needs another oil change. 5-speed so I suffer from the dreaded lead foot.

Thinking about getting better grounds,and an intake. Maybe lighter tires/wheels will help too.

My first tank sucked, about 22MPG, since then it's been gradually getting better as it breaks in. Now it averages about 35MPG mixed city/highway (daily routine) and in the 40s if it's all highway road trip. AC seems to make little difference in mileage.

05 ex, standard. ~10k miles

**** right now I am getting exactly 30 MPG driving 95% highway driving and 5% city driving. I wish I got 40 MPG as some people, driving to school everyday kills me.

05
19 mpg

thanks everyone for the their feedback. Seems like the MPG ranges very differently among people in this Thread. I see from 18-40 MPG. Thats realli a big difference. For those with 30 MPG and above, what type of gasoline do you guys use? Maybe that might be a factor of the MPG?

Also Im confuse on how often we need to oil change the 05 civics. The manual says every 10,000 miles??? Isn't that a lil toooo long.. what do you guys recommend? 5K?

I've always used Plus Gas. Prices are so high lately, down here in Miami Plus is $2.53 and premium almost $2.70. I used to be able to fill up my tank w/ $15...ppsss....now it won't even get full w/ $20.
Regarding MPG? Maybe 22-25 the most on the Hwy...

Theres's a few threads on oil changes...you may find more info. there, but I do mine myself every 3k-4k miles...

The milage also makes a differance. I've had 2 7thgen civics now and notice once you hit about 15-17k miles, the mileage goes up. Both (one manual and one auto) got around 28-30, then when they hit 15-16k, they went to about 40 MPG. Long term break in is a factor for that ones I've had anyway, I also knwo it is for the M3, infact it leaked burned oil for the first 15k, then stopped.

i use regular 87 octane at quicktrip, and BP's. my car LOVES BP gasoline. i have gotten almost 500 out of the tank when i filled up with them, it was like 480.

 
Rep Power: 319

Another good point, I notice higher octane seemed to burn quicker and thus I got worse MPG with 93 than 87.

 
Rep Power: 282

93 actually makes the preflame phaze slower, but the actual combustion speed is exactly the same. The 93 and 87 are exactly the same quality wise, same cleaners and everything it is the law. The only reason to use higher octane is to reduce pinging/knocking for higher compression, performance type engines. Always use the recomended octane rating in your manual unless you are boosted or spraying nitrous. The only effect that using higher octane rated gas then recomended would be a nasty rotten egg smell that comes from you exhaust because you are damaging your hurting your cat.
