Bad mileage 2009 civic coupe

[CivicCoupe09]

Hey guys my 09 civic coupe automatic is only getting about 440KM to the tank, and this is after i push it on the Low gas light a bit...has about 12,000KM on it...ideas?

Depends on a few things.
Have checked air filter? How hard are you driving it? Are you warming the car up a bit before driving it? Cars tend to use more fuel when the weather is colder. If you start driving right away and the engine is still cold, you use more fuel. Even while warming the car up, idling will use up more fuel. How hard are you driving it? Are you doing a lot of stop and go driving? Tire pressures are correct?

I'm driving it like a bat out of hell lol, so that may be a problem..I'm actually on winters right now and i'll check inflation today after i fillup..

I'll drive it like a granny this week and report back

I also have a question and didn't wanna make a new thread. I get about 460km on my 2000 Integra GSR. Is this normal? I don't drive it hard at all.

[Pollywog]

My '06 civic commonly got 800kms a tank...

And trieu, if you have decent mileage on the GSR, 450-550km is pretty average. Of course, not so say a tuneup couldn't improve it a bit.

[Zewind]

I have an 07 Si, in the summer i get around 400km to a tank.


I have a CAI, but nothing else has been touched.


I feel im on the lower end of the norm

[Disoblige]

lol?!

45 L tank for the newer civics right?

800 a tank? That's pretty careful driving Pollywog..

[GQBalla]

If you drive it easy and shift at 3k rpm and properly down shift with the foot off the gas while leaving the car in gear you'll be surprised at the fuel mileage

Lol, it's not like I had to drive super-grandma style to get decent milage on it (35-40mpg, less in town). It was great, just a little lx civic w/5speed.

PS: 50L tank.

are you serious? so you think that you will get good gas mileage when you push your car?

:facepalm: I dont know how I missed this but this is the cause of your problem. Quit driving like an asshole, check your pressures, and move along.

I drive an 08 civic si and I usually get about 450km when the gas light comes on.

si's get worse mileage than base models.. roughly 20%

I get about 600km in the city to a 45 litre tank in my 2009 Civic DX-G. Is this normal?

According to honda.ca an auto coupe has a range of 609 km in the city if you used up every last drop of fuel. Since most people fill up before their car runs out of gas this number will be lower in real life. Also if you drive agressively it will go down even further.

How much gas do you put in typically when you refuel is the better question? Your car is rated for 8.2l/100 kms in city driving so if you put in 40L every time you fill up you should be getting around 490-500kms between fill ups.

Edit: Highway rating is 5.7L/100kms. The more driving you do on Deerfoot or Crowchild for example the better your mileage will be. There is a big difference between City driving on McLeod trail at 4Pm or Deerfoot at 10pm...

you can do the calculations yourself. the standard in Canada for gas mileage is L/100km, so you are getting 7.5L/100km (45L / 600km).

if you're a manual, you're just about right, automatic, you're doing a little better than EPA or energuide. keep in mind that their tests consist of a standard route, which may or may not be reflective of how you drive.

Also ive seen where some people think they drive nice and they really dont.

few tips on driver correction .

accelirate slower than the car beside you when the light turns green. follow that buick doing the speed limit instead of roaring passed him.
keep it below 3k rpms and 2.5k for v8's

I don't have a Honda Civic but I have a 2007 Honda Accord 4 cylinder. My gas mileage is currently averaging 10.2 L/100km, when I first bought the car I was getting around 8.7 L/100km. I drive pretty much the same and am wondering if a fuel system cleaning is really necessary for a newer vehicle w/ only 42,000 kms?

42000 is plenty of time for a car to build up crap in all of its systems..

i would do a seafoam, check the tires, replace your air filter. also if you're using a heavier weight oil it will affect your gas mileage as well.

i Fill it up, cost about 40 bucks rate is 93 c a litre so about 36L or so? I'm driving it like a grandma right now just to see what happens ill report back in 1-2 weeks

36L over 440kms works out to exactly 8.2L/100kms which is what the car is rated for in the city cycle. (36/440=x/100)

You're leaving 14L in the tank when you fill up so you could drive another 100kms easily on that tank.

well apparently i fail at math but 40 bucks is about 43 litres.. so 43L/8.2 524KM in the city..i should be getting another 100 clicks...

Yeah but you already identified the problem above. Drive more conservatively, don't go immediately from the gas to the brake (i.e. anticipate when traffic is slowing down and lift EARLY), slow down to within 5km/hr of the speed limit and you will see your mileage improve drastically. If you constantly accelerate to 10-20km/hr over the speed limit that is a lot of fuel you are throwing away each time you stop, and if you are on the gas right up until you need to brake for traffic that adds up too.

You are within ~10% of the correct mileage for your car, you should be able to straighten it out if you drive smart. That said, 1 tank is not nearly long enough if you have been driving like an ass for a long time ;)

For anybody else complaining about mileage, drive at least 4-5 tanks and always fill consistently (same station, shut off at the same point, etc.), then total up the km's and litres of fuel and you can find your average mileage over that distance. If you post that here it is way more useful than posting how many km you get to a tank because not everybody fills their car the same so even if we know how big the tank is we do not know how much fuel you are putting in it, therefore making it impossible to give you accurate opinions.

Check you air filter and tire pressure.

Try driving like a grandma to see if you get better mileage. Do you have a LOT of stop and go? You will get no mileage get stuck in DT/Deerfoot traffic. Try to switch to routes that get you moving.

I never get factory rating with my 96 Civc because I drove it like I stole it. I average 9-10L/100km combined back then with a 1.6L engine.

[Shlade]

quit driving like an asshat, your mileage will be fine then

[sneek]

I am getting about 10% worse than EPA numbers right now. I am on winters with occasional spirited driving.

According to Fuelly I am getting 21.9MPG and I should be getting 24MPG. The car is 7 years old now and has 165,000KM on it. I am probably due for a air filter change in the next few weeks here though. The majority of my KMs are in the city, other than 3 trip to Banff and 2 trips to Edmonton the mileage is all city.
