Could be 02 sensor. I had a flaky one on my old CRV and the car would alternate between throwing an O2 code and the gas cap code. Could be due to the above explanation as well; I never did get to the bottom of it. (And I didn't replace the 02 sensor as it wasn't a constant problem and the car ran fine).

30mpg is quite fair. I have got 33 so far in mixed driving. And I am, honestly, I am really careful about driving slow. If I drove "normally" I think 30 is quite reasonable. I wouldn't be worried anything was wrong at that level. Low/mid 20s maybe. The car's got a poor power-weight ratio and it's not very aerodynamic on the rear. Honda makes a great Insight on the same platform if fuel economy is more important. Then again Toyota makes an even better Prius, which is in another price range entirely but anyone can get 50mpg in it.

That said if your car is throwing a code there's at least something wrong. It may be related to the gas mileage or it may not.

 

I've had the gas cap message on my car. It's always after the weather gets warm in the late afternoon right before I leave work. I think it's just fuel vapor causing a bit of pressure difference. It's only happened in the summer and not necessarily on a full tank of gas. The MIL has never come on for me, though, so I ignore it. There was another thread in the past that had a number of people wondering if this was caused by fuel expansion in warm weather.

 

That's classic!

 

In what way?

Below average mpg, not average. As anyone except die hard Fit and/or Honda loyalists like you and Steve 24loser can see.
There are legitimate reasons for me to be disappointed about my Fit. So explain how that comment is "classic." Your statement is absurd, and you bring absolutely nothing to the table by posting here.

 

The malfunction code was just the gas cap. The honda dealer didn't even replace it, just wiped the code.

 

I had nothing to say about the comment:

"Originally Posted by Steve244
Wait, this is your mom's car. She drives it most (all?) of the time. So far you've told us she's getting average EPA MPG. Then you go off on a rant. It sounds like there's another problem here."

I was commenting about the second part:

"Tell us more, about your mother."

There's plenty of humor in that statement, implied or explicit.

And as far as bringing something to the table, Fitfreaks here will tell you that i have brought a lot to the table, although not in this specific conversation, simply because others have done it for me. I am not a brand loyalist, this is my first Honda. I simply enjoyed the humor in the statement "Tell us more, about your mother."

I do, however, agree with many who have posted here: you certainly have a little sand in your vaj, and should sell the Fit. No car is perfect.

So, who's statement is absurd: "As anyone except die hard Fit and/or Honda loyalists like you and Steve 24loser can see". Again, this is my first Honda. I agree with many of you, I would not buy the other cars honda produces. To make that statement with only one data point, is in itself, absurd.

In the scientific world:
1 data point is an occurrence
2 data points is a coincidence
3 data points is a trend

Per that logic, I would have to buy three Hondas to be confirmed as a "die-hard loyalist", at least 2 to form some sort of trend.

in closing, please please tell us more, about your mother...

 

30 mpg is smack dab in the range of average mpg. The fit bas auto is rated at a combined number of 31 mpg. Even just the switch from mtbe fuel (in the spa tests) to e10 fuel (what's actually sold) can entirely account for the 1 mpg difference, much less AC use, traffic, hills, etc. Unless you believe that all cars regardless of driver, traffic, climate, terrain, fuel, commute, etc, should all get exactly the same milage, a clearly absurd belief, then within a few percent of the advertised rate is clearly acceptable.

 

Why should 30mpg be acceptable when 80% of my driving is highway? Why should that be acceptable when tons of other people, driving in similar climates, driving their cars hard, with AC on all the time, are getting 35+ as Flygirl is? What is it about your clear obsession for Honda that prevents you from understanding that what Honda is selling with this car is not what I received??? WHAT IS SO DIFFICULT TO UNDERSTAND ABOUT IT???????????????
Forget it, I'm done trying to convince you. Your clear bias toward every single thing Honda is completely obvious, to the point that you will never accept the possiblity that they have a) lied or b)failed. Never mind the Consumer Reports Civic issue, or the lady in California's Accord Hybrid issue-- there's always going to be an excuse with you regardless of what the facts point to.
God DAMN you are ignorant.

 

This thread is clearly non-productive for you. You're welcome to continue banging your head on the wall over it. My solution to this problem is to unsubscribe, block and breathe a sigh of relief.

 

This is a web site for Honda enthusiasts. Of course were not gonna like it when someone talks crap about Honda...Thats the standard response on any enthusiast site

 

30 mpg is not bad enough to complain. Did you take it to the dealer and what did they say? Have you done a idle relearn? Check the battery? Use higher octane? How many Hills and how many miles per trip? The throttle body actually works better if you release the pressure off the pedal a little at cruise but that is what premium gas helps you do without losing speed. Do you drive with the defroster on? There is many reasons the mpg is lower then you want but its up to you to try different things before ranting about it. Many problems are drivers error and the little old lady case should have been dropped until she proved all the variables have been discussed. Its not up to Honda to teach you how to drive.

I understand your not happy and I got rid of a car that got 20 mpg that I get 40 mpg in same type of car. I would have been happy with 30 mpg.

 

And people wonder why I left Arkansas....

Last part first. I'm not particularly biased toward Honda. They've had a bunch of missteps and mistakes lately. But claiming, for example, a case from California that Honda won (yes Honda won the case; who's ignorant now you inbred looser who has to go live back home with your parents) shows something about how Honda is slipping is clearly ludicrous. I'll certainly grant that the civic redesign badly missed, that the Accord designers are lazy and been surpassed by most other car makers for the mid-full sized class leader, that the Odyssey costs 33% more for the equivalent Chrysler product, that Acura stuck with a common design element (the front beak) so bad it made 1/3 of potential owners drive off the dealer lot when they saw it, etc. It's unlikely my next new car would be a Honda; the company has clearly lost its unifying goal. No I'm not a Honda zealot. That said, the Fit, probably because its at the bottom of the sales sheet, got missed by Honda's "lets screw up our entire product line" initiative.

Next, Flygirl is an alt of a poster who just liked to stir the pot here; taking those numbers at face value is gullible in the extreme. Moreover, Az and Ar, though they both start with Ar and are filled with idiots, are not all that similar from a car driving point of view. LR in particular can have some hills, lots of humidity, poorly designed traffic flows, etc. Moreover, as I've pointed out, when I lived in LR (so certainly a lot more similar driving circumstances to you driving in LR compared to someone in a different state) I got about 30 mpg.

Finally, assuming that your normal drive really is 80% highway, and I thought your real numbers ended up being closer to 60-70% somewhere in the thread, and interpolating the EPA numbers (assuming its a purely linear interpolation which I'd be reluctant to assume) you get that your overall milage should be 33.6. Basically within 10%, and that ignores that the EPA tests use an optimistic fuel assumption (mtbe), leave off the AC, etc. What I see is someone who's getting very close to the stated numbers. Should everyone everywhere get exactly the EPA numbers? Or are you just so special that of course you should be above the average?

 

Just out curiosity, at what speeds on the highway? I noticed that after 65 MPH, the MPG numbers start falling, and at 80 my, its pretty much 30 MPG.

 

Or... to commit suicide. Either is acceptable.

The OP:

I know you missed the point. This thread has gone beyond productive... Now everybody here wants to piss you off. Guess what? It's working.

 

Well, as others have pointed out the rated combined mileage is 30, so you're actually bang on. If you want better mileage with a small engine (or any engine really) like this you need a manual and know how to drive it for mileage. Automatic transmissions suck power.

Yes, I'm one of those who are getting more than 35, closer to 40 and even a little above for my regular commute. But my commute is rolling countryside where I can get up some speed then coast for miles at a time without ever touching the gas. Mileage tends to be on the higher side when you don't touch the gas pedal.

Went into the mountains for some mountain biking over the weekend, which brought me down to 35 for this tank. But again, I'm driving a manual transmission.

That said, there *are* things that can affect mileage without tripping engine lights. In addition to things like a sticking parking brake, or rubbing brake shoes, a stuck open thermostat that keeps the engine in loop will affect mileage greatly. So can a faulty coolant temperature sensor.

Unfortunately the Fit doesn't come with a whole lot of gauges. I've got a bluetooth obd dongle and Torque to check that stuff while driving.

 

Something like an Ultra Gauge might help then?

On the highway I'm getting 5.9 L/100km (39mpg) with no AC
with the AC on I get 6.4 L/100 km (37mpg)

In the city I get 9.1 L/100km (25 mpg) with the AC on.

In my old GMC Acadia I would get 13L/100km and my KIA Sportage would get 15L/100 city. Neddless to say I'm happy now

 

I suppose but I prefer a [bluetooth OBD dongle](Amazon.com: BAFX Products (TM) - BLUETOOTH - OBDII OBD2 DIAGNOSTIC SCANNER - CAN ELM 327 SCANTOOL - CHECK ENGINE LIGHT CAR CODE READER: Automotive) and [Torque](Torque — OBD2 Performance and Diagnostics for your Vehicle) if you have an Android phone. Less than half the price and more functionality.

Although if you have an iPhone you need a wifi dongle, as the iPhone doesn't correctly connect to the bluetooth dongles unless you jailbreak it. I think the program for iPhone to use is RevII.

 

This thread was hardly EVER productive, except to show what a bunch of diehard ne'er-do-wrong Honda loyalists/apologists most of you are. There was only ONE post that actually tried to help, before going berserk because of my (correct) insistence that this car is not providing what it is supposed to provide. I don't care if everyone on here wants to piss me off for speaking the truth about this car, and from my vantage point, it's everyone else (inlcuding you) that's pissed off because someone finally spoke up about your beloved less-than-stellar car. I was duped, but I'm neither proud enough to deny it, nor naive enough to keep convincing myself nothing's wrong, unlike the rest of you. So keep patting yourself on the back, while trying to justify your purchase and worshiping Honda the gods of auto manufacturers who haven't done much right in a LONG time. As for me, we have decided to sell. Because this car isn't worth it.

 

That makes you a fool. Again, I didn't come on here to bash Honda, I came on here to get some info/suggestions as to what might be wrong, but what I ended up discovering is you all are more interested in sucking off Honda than you are in actually helping, and god forbid anyone try to be honest. All of you coerced me into really railing against them because their minions (namely you all) have all sold your souls to them and don't have enough free will to admit Honda is on a downslide as has been for a while.

 

Then why does Honda list the manual tranny as getting worse fuel mileage? Basically, what you are saying is that they fudged the numbers on the auto tranny so more people would buy it even though they couldn't get the actual mileage they quote.
And I am fully aware of how to drive a manual for either a) performance or b) economy. My mom is not. Thus the auto tranny.
