FTFY

But yes, you shouldn't have to be in neutral downhill for the injectors to shut off. I can go downhill in 3rd gear with no throttle and the MPG will read 80, this is with MT but I don't see why it would be any different with AT.

 

FWIW, the injectors won't shut off if the car is in neutral because the transmission isn't turning the engine, and the engine would die. However going downhill at 60MPH at idle you're getting ridiculous mileage anyway, well over 100MPG.

That's why I recommended trying to put the car in neutral and see what happens.

 

1) Cruise drops MPG by 5-10% from my experience
2) That's because the car is braking/engine braking to keep at your desired speed.

 

Yes, agreed, I don't think you'd be able to tell the difference in fuel use on the MPG meter between downhill in neutral and engine braking. You'd need a scangauge or something.

I've never went downhill in neutral, so IDK about that, but I know staying in gear coming to a stop gets me better MPG than rolling in neutral.

 

You know what i see in this thread?

A troll and it's victims.

Everyone's trying to find ways to justify the Fit to some that calls everyone a "brand loyalist"... curious, wouldn't hating a car, and still keeping it be viewed as a brand loyalist?

As another victim of the troll, I'll say these things.

EPA highway tests are all done below 60 MPH... and that is the best case scenario for MPG. EPA's "high speed" test reach 80+ MPH, but their results are not individually shown, only used in the combined.

Is the OP ever willing to drive for a whole tank, without going over 70 MPH at any time? No?

The instantaneous MPG gauge is useful for what's basically going on, but not that accurate for what's EXACTLY going on. Results over a whole tank (or better yet, multiple tanks) are better... but only if the driving conditions are consistent (and reveal accurately).

My bet, the OP is constantly driving at or near 80 MPH and that's all there is to it.

 

You said 80% of your driving is on the highway, what is the other 20% like? You said you can't drive the car like the EPA does in its test to achieve the highway # or you will be killed, so obviously you are driving much faster. So you expect a tiny engine pushing around a not so aerodynamic vehicle that only gets worse as speeds increase to give you the EPA highway number? Who is the blind follower? YOU ARE OF THE EPA TEST!!! When I never get on the highway and having to deal with the traffic as I do, I can see as low as 9km/l (21mpg) when I fillup. Ohhhh PHUCK YOU HONDA, you lied to me and your QC has fallen to below the almighty ship builders from Korea, somebody please join in with me in the bashing and stroke my clitoris to make me feel better.

As already stated, just get rid of the car and get another, instead of coming here looking for others to soothe your whiny ways and join in on the EMO circle jerk and calling out Honda as the bad guy and lying to specifically you because your car doesn't get the numbers it does. So what about all the other people that achieve better, Honda lied to them as well right? Your feeble brain is just too possibly in-bred over the family line (yes not tree) to just realize all of the factors at play that have been given to you. You won't take the car into a dealer because you said they will say nothing is wrong with it, but you swear something is. Another forum member was getting almost identical mileage as you are getting when living in the same region, now gets more elsewhere, but something is still wrong with your car and Honda is a failure and liars on top of that.

Why you haven't been put on ignore yet, I don't know, but the time has finally come. I cannot stand the "Idiocracy" that is so prevalent today.

 

EPA tests are for comparison between cars only, I don't know what's so hard to understand about that. The OP's mileage wasn't horrendous either.

In any case I'm def glad to have the MT as it seems a lot of the big whiners about mpg have the auto trans.

And to the OP, it is possible there is something defective in your car but more than likely you simply do not drive in a manner that is conducive to good fuel economy.

 

All true!!

I am one of those AT owners, and I am hopefully not whining too loudly because I knew that although that manual is rated lower by the EPA, it's a lot easier to eke out some extra MPG on a manual than on an automatic. I have never encountered a car where a skillful driver could not do the same.

Final advice to the troll (I enjoyed the thread btw): Diesels are well known for handily beating the EPA test in real world driving. I would guess than nearly any gas car is going to disappoint you vs the EPA rating; but with a diesel it's real easy to exceed it. Unfortunately the cheapest option is, I believe, a Jetta; this is a problem our European neighbors run into all the time - a diesel engine is a lot more expensive to build than a gas one, and so you pay more up front but earn it back over time.

 

Who's the more trollish; the troll or the troll who trolls him? [/obi-wan]

For accuracy's sake, I'm currently getting a bit worse milage than when I lived in LR, mostly because I don't have the time to take the longer way/go to the better grocery store. Toddlers suck up free time.

 

You sir are my hero

 

Sheesh, chill man. I know one thing about mine from driving it near Branson. Hills kill the MPG. This small engine does not handle them well. If you are dealing with them a lot then that may be the problem. I know another thing about it trying to get the best mileage with any car. USE THE CRUISE, if you have it.

 

If you are getting engine braking you are on the downside of a pretty good hill. I always take the cruise off there. It's not a good time to use cruise.

 

I get widely varying mileage. I have driven mine all over. The mileage has ranged from about 30 to about 40. The average has been around 37. Hills kill this little thing. Wind really plays havoc with mileage also. That all said, I don't have to deal with those two things much. I know one thing. I wouldn't want this car if I lived in the Ozarks or any other hilly place.

 

I drive my car in San Francisco fairly often (I work there) and I wouldn't say it kills my mileage. I could still average 33/35 in my CRX. Haven't driven my new fit enough for a good sense of what it usually gets.

 

Engine braking doesn't use any fuel.

 

Yesterday afternoon, and coming in to work this morning, I REALLY kept an eye on the mpg meter, trying to keep it at around 40 or above however possible. It seemed to act exactly the way everyone on here said it was supposed to act, so I guess its OK, no drop ion the meter when going downhill (in fact it pretty much went up to 80 every time) and always drops below 40 pressing the gas in ANY manner. Anyway here are the things I noticed:

1) It doesn't matter how slow you start up from a stop, any acceleration drops the mpg meter to around 10 and it stays there until about 3rd gear where it starts climbing.

2) At any point, if I tap the gas, and I mean TAP, with pressure that wouldn't kill a fly, the mpg meter drops below 40, usually to around 30-35. It is VERY tough to find the fine point between keeping your foot on the gas enough to keep up speed without sacrificing mileage and losing speed. Other thing is, it inherently hurts fuel mileage because inevitably, at some point you will lose speed (even on a flat) simply because you aren't pressing the gas enough trying to stay around 40 on the meter, and ANY further pressure knocks it down. Cruise does help this on the interstate (actually quite a bit I would say) but around town not much can be done.

3. I think the perfect fine point on the interstate between keeping decent speed and decent fuel mileage is 68 mph. Any more (even 69) and there are more often drops on the meter. If set at 68mph on cruise, I can pretty much keep the meter at or slightly above 40 unless I encounter even a slight hill.

4. Any time this car encounters an incline, ANY incline, mileage drops to 30-35. Even if the car doesn't shift. A 1 degree slope and the meter drops. This is true whether you have it on cruise or not.

5. I put the car in neutral and coasted up to several stops. Other times I left it in gear. Maybe coasting to a stop helps a tiny bit, but either way the meter ALWAYS went up to 80 when I was slowing down, until the car is almost to a stop.

Now having said all this, its taken my mind off any issues with the way the car shifts, either by trying to drive it in a way to keep the mileage up I have made the car shift better, or maybe it's just that I don't think about it since I am concentrating so hard on the fuel mileage. I still think it's a little ridiculous the amount of effort you have to concentrate on the EXACT way you are pressing the gas pedal just to get the mileage Honda claims, but we'll see how this tank of gas goes, and I will post ACTUAL non-exaggerated mileage.

Now, one more question, is there ANY way to work the pedal in this car on acceleration so I get more than 2 bars sooner than 3rd gear?

 

Okay, what you just posted sounds about normal.

I think you might have had your foot on the gas pedal previously if it was dropping when going downhill. In my manual, the car can slow going downhill even in 5th gear. Mileage meter drops even going downhill if I have to use gas to keep up a little speed. This is an electronic throttle not a mechanical one, so even a little pressure on the pedal and you're burning gas. You really can't rest your foot on it like you could older vehicles.

Every car acts the way you describe, it's physics. Seeing how I ride a bike I can tell you it's easy to pedal forever and use very little energy on a flat road. As soon as there is the slightest incline, it takes significantly more power to maintain.

Just gotta get used to the way the car drives, each car is different and takes adjustments. Seems like a lot of "work", but after you drive it a few times and get used to driving it that way it becomes second nature.

Don't worry so much about the meter when accelerating. You want to accelerate smoothly and quickly, but not like you're drag racing. The quicker you get up to speed the better, but too quickly and you're using more gas than you should.

 

#1: Yes just muscle memory, after a while it becomes second nature.

#2: 100x yes, you don't need to accelerate like a granny, you burn more gas SLOWLY accelerating, the faster you're able to semi-coast the better, like SgtB said, don't dump the throttle like your drag racing, but a slightly spirited run up to speed is A-OK, just be smooth on the throttle.

I'm glad your figuring it out some

 

and let me just re-quote that for good measure.

seriously tho, threads like premium vs regular and 45mpg vs 25mpg is really getting to be irritating... there's probably hundred threads of same topic.

 

Nobody asked you for your input, and the fact that you waited until 27 other people on here had already railed against me before showing your face to make sure your view was supported makes me think you are too much of a chickensh*t to have ever taken any risks in your life.
