Yes. I don't think you know how to do the math correctly. Take pictures of your gas receipts with mileage, and then pictures with the average mpg display from the car.

Woo! I am the king of page 26!

 

I am the queen! Woo! .. wait. Never mind.

It's normal for some people to get lower mpg than the EPA estimate. It's normal. You're pretty close.

Trolling is something you may or may not be doing, but just like a lot of stuff people say online, none of the other readers can determine if you are actually intending to do it or not .. sorry We can only make an assumption and each person has to do their own.

 

If you're resetting the trip meter at every fill up that's reseting the average millage as well. If the computer is constantly showing 33 ish mpg average and you are consistently only averaging 28 that's a surprising discrepancy.

 

Well he's said he's never reset it, and he resets it every time he fills up sooooo theres that...

 

Yeah, the feedback loop appears to have far too much noise relative to the signal.

 

Seb, as Martin used to say "get the stepping!"

I cannot believe the good members here have tolerated you and you super dumb posts and comments.

Your, excuse me, your mother's Fit, is EPA rated at 28/ 35/ 31 MPG ON THE EPA CYCLE. That's it. No more no less. They, not Honda, state those are the numbers achieved according to their standards.

Furthermore, I cannot even count how often they state that those numbers are only to be used as estimates. KEY WORD "ESTIMATE".

I cannot believe the nerve you have to come here, take advantage of this friendly atmosphere where all members usually help one another, and complain about your MPG even though you clear get within the range of the EPAs stated numbers. It's like bizarro world. Lol.

Do you know that the 2012 Impreza is rated at an EPA 27/ 36/ 30 MPG and that many owners report getting 24 MPG combined? I don't even want to know what you would do if your MPG were that much lower than EPA consistantly.

You clearly are a joke and I KNOW that in person, people wouldn't give you the time of day.

Also, you must be too stupid to realize that MPG is not only affected by city vs highway driving, but also by the temp, ac use, wind, alignment, air in tires, THE NUMBER IF COLD STARTS (since extra fuel is used to get the engine up to operating temp as soon as possible to prevent wear).

Thus, going though 10 gallons within a week (full with heaps of cold starts) is VERY different than going through 10 gallons straight while on a road trip.

I, not my Moma, own 2 Fits and you will never find a post where I really get into MPG threads. I have gotten anywhere from 28-44 MPG. All due to different driving and enviromental conditions!!!!!!! That's it. No more no less.

Lastly, you even complained about changing the spark plugs on the fit because spending an extra 5-10 minutes removing wipers and a cowl is too much for you to comprehend. I litterelly feel so sorry for you as you know nothing about cars in general and even less about how many cars ARE ACTUALLY A PAIN THE BUT TO CHANGE PLUGS ON.

I remember that on one model ford f150 it was an 8 hr billable Process to recharge plugs at a dealer.

Do you know that on the new Scion FR-S and Subaru BRZ it's an 18 step process where the engine needs to be lifted, exhaust removed, hoisted, etc to change plugs?

If only I could be a fly on the wall to see your face if you were a BRZ owner and found out it's 6 hour plus job with special tools needed to change plugs. Just thinking about it cracks me up.

The laugh is short lived cause then I remember that you AREN'T EVEN A FIT OWNER!!

Since your not a Fit owner, maybe head over to the ford and subaru sites and complain about their cars as well. You clearly have no life and you will have just as much legitimacy there, being a non owner, as you do here.

Get the stepping!!!!

 

18 step process for the plugs on those? Probably the most interesting thing in this thread.

I'm pretty sure you all have been arguing with a minor. No offense to some of our younger members. If this were real life, and everyone was in a room together, I think it would be shamefully ridiculous, the disparities.

 

You said you reset the trip meter every time you refuel. AND you said your avg mpg is for the liftime of the car.

READ YOUR OWNERS MANUAL AND OBSERVE THE GAUGE! Everytime you reset the tripmeter you ALSO automatically reset the avg!!

You have the observation of a doorknob.

 

The average mpg readout is the average since you last RESET THE TRIP ODOMETER, which in your case is NEVER, so it's the LIFETIME AVERAGE of the car and not what you got over the last tank.

Pretty damn good I'd say for a driver that doesn't know how to operate the car.

Sorry I don't normally shout.

 

Interestingly this might explain all of it:
1) MPG wasn't as high (33) as mom was expecting (35?). (Complaint 1)
2. Mom gives car to son. Son drives faster, mpg (28) appears to "get worse over time" (Complaint 2) but it's not a clear change as they both drive sometimes.
3. Son calculates mpg. By-tank mpg is not as good as the display (Complaint 3) ... because by-tank mpg is his own, and the display is the cumulative mpg including when another driver was the primary one.

I think those were the 3 primary complaints. Except about Honda loyalists. I don't consider myself one actually (I'm more of an Honda enthusiast but I buy where the product quality is), and I'm not touching that one.

 

My theory for the OP: Let's say we have two readings; the vehicle MPG gauge 33.4 MPG, and the calculated MPG, Miles driven divided by gallons used 28 MPG. So at 100 miles, by the vehicle 33.4 MPG gauge, you would have used 3 gallons. If you filled the tank at that point you would have had to pump in in 3.6 gallons to get the calculated 28 MPG. In this scenario, the only constant is the 100 miles driven, (of course there could be speedometer error but for this scenario, let's say there is none). I know from past posts, that owners have been able to "squeeze in" more than the specified fuel capacity. Looking at it another way, the vehicle gauge thinks it used 3 gallons, you were able to top that up by an additional 0.6 gallons resulting in a calculated 28 MPG. My recommendation to average out the variables, is to fill up under the same conditions at least 5 times, (10 is better), then divide the total miles driven by the total gallons used over that 5 fill up period. Then come back and report your findings. Otherwise there's just too many variables to make an accurate determination if you actually have a problem.

 

whoa whoa whoa....whats with the language here?

 

I seriously doubt you really need to remove the windshield cowling to get to the plugs.

The official procedure for changing plugs on the Nissan I traded in was to drain the coolant system and completely remove the intake system (as coolant and intakes are usually tied together in modern cars), as well as remove the cowling, wiper arms and motors.

I replaced the plugs, packs and valve covers on it without doing any of that.

 

That's really unacceptable engineering. Plugs and other consumables should always be easily accessible. Kind of like the idiots who designed that Dodge Stratus where you had to take off the front wheel and remove the wheel well to get to the battery.

 

Not to totally suck up to honda, but with an expected replacement interval of 100,000 (i.e. on the order of time most timing belts are expected to last), it's not totally crazy to have it be a bit inconvenient. Besides, it's just a piece of plastic to pop out. It's a bit bigger deal for non-USDM cars as they don't get the iridium plugs (or whatever the magical element is).

Everything with shorter intervals is pretty easy to do. Drain plug rather than having to drop the pan on the AT for a fluid change for example. It's just that small front wheel drive cars don't have a lot of space.

 

Inconvenient is one thing, but to have to virtually remove the engine to change the plugs like that Scion is unacceptable. At least looking at the Fit changing the plugs looks magnitudes easier than the Altima I just traded in.

Similarly, that Altima required the engine to be completely taken out to change the clutch. You could get around removing the engine, but the workarounds were such a pain in the ass you might as well just take the time and remove the engine. Up yours, Nissan engineers!

Conversely, I changed the clutch in my Miata in about half an hour in my driveway. That car was a joy to work on, despite it's small size you could just about stand in the engine bay.

 

My bad boss, I just thought with curse words being thrown about left and right and all the other rule breaking going on it was fair game ITT.

I apologize.

 

So here are the results of my trip to Dallas:

on the way down: 39.1 mpg
coming back: 36.3mpg

Now here's the funny thing: On the way down I kept the speed at around 68-69mph, and the average mpg display actually read 41-42mpg until I got to the Texas border. After I crossed into TX it steadily declined until I got to Dallas at which time it read 39.1. Still not bad, I figured the decline was probably due to the fuel pump having to work harder as the tank emptied.
However I refilled the tank before heading back, and on the way back I went a bit faster, around 73-74 mph. While in TX it constantly read around 34-35mpg, then when I got back into AR it actually CLIMBED to around 36 and read 36.3 when I got back home!
Only thing I can figure is lower pavement resistance in AR.

 

So, there will be mass apologies to all the Honda loyalists?

 

Hum, I doubt that.

Man, I thought this thread had finally died and the OP had moved on to annoying another car forum... but it clearly is unfortunately not true.
