Not sure if I have calculated correctly but I have used this Conversion Type Formula:

Based on 1 gallon = 4.55 litres and 1 mile = 1.61 kilometres

mpg to km/ltr km/ltr = mpg X 0.3538461
mpg to litres/100km ltr/100km = 282.608/mpg
km/ltr to mpg mpg = km/ltr X 2.8260873
km/ltr to ltr/100km ltr/100km = 100/(km/ltr))
ltr/100km to mpg mpg = 282.608/(ltr/100km)
ltr/100km to km/ltr km/ltr = 100/(ltr/100km)


After two first tank filling I've got:

Highway 6.1 ltr/100km = 46.3 mpg
City 7.3 ltr/100km = 38,7 mpg

Is this good numbers for my Jazz 1.4L CVT ('07)?

And, those numbers is read from the cars computer (the display with ltr/100km or odo or trip).

 

second tank 34 mpg 20% city 80% hwy. sport a/t.

 

According to the following table the calculation is correct, but usually the figures written hire are mpg (US)

Imperial and Metric Conversion Factors - Table - MSN Encarta

Your figures are equal to the 5000miles average of my Jazz. (see link)

From my experience (two Jazz) the computer is off about -0.3l/100km compared to the calculated figures, to be sure about the real numbers you may calculate also.

 

i'm averaging 31 mpg on conservative driving 90% highway, 10% city. its weird cos i did a road trip that was all highway and averaged 28 mpg, but maybe it had alot to do with the drive being in the mountains?

 

Check this out.......

I stop averaging the mpg of my Sport manual since I was geting 32MPG constantly, so (anyway I am happy with 32MPG) and today I found this on auto spy car new used at Autospy.com:

they put the Fit (with the new mathod) worst by 11.76%

I am still geting more than that and I am a heavy footer!!

P/d I leave the Escape because my wife has one


The EPA has published estimates of the affect of the revised methods for estimating vehicle fuel economy—which apply to model year 2008 and later vehicles—on earlier model year cars as a way to educate consumers on the likely impact of the changes.

Compared to today’s estimates, the city mpg estimates for the manufacturers of most vehicles will drop by about 12% on average, and by as much as 30% for some vehicles. The highway mpg estimates will drop on average by about 8%, and by as much as 25% for some vehicles.

A couple of quick checks give us the following results the following:

Old New

Hwy City Combined Hwy City Combined Drop




2006 Ford Escape 26 22 24 23 20 21 12.50%



2007 Honda Fit 38 31 34 35 27 30 11.76%

 

Everybody here uses US gallon.

1 US gallon = 3.7854118 l

 

nice, 2nd tank after first oilchange, 36mpg ... this would be a thing to celebrate ... if it wernt for the fact that my first two traffic tickets were recieved on this tank ... stupid cops ...

 

32 mpg for the first 3 tanks. About 3/4 of my driving is 65-75 freeway with a long mountain climb in it. 1/4 suburban driving.

By comparison, my '06 Civic got 38 to 40 mpg on the same route, using the same fuel. My dad's Buick LeSabre got 29 while my Civic was in the body shop for two months. My '99 New Beetle diesel used to get at least 44 mpg on the same commute and had far more power.

I'm very disappointed. This car is far too underpowered to get decent fuel economy. If a tiny Honda "economy" car can't beat a 200 hp, full-sized Buick by more than 3 mpg I'd have to say it's not a very good deal.

 

Quit climbing hills

 

My Wife drives the Fit, mostly in inner city driving. Overall for the first 3200 miles the car has only averaged 24 MPG. On a couple of trips with mostly highway driving the mileage was over 30 MPG. Dealer says the car has not yet been broken in and it should trend upward.

 

third tank 30 mpg auto sport.

 

Yeah!! I know the feeling

 

Just posting my #'s

well if i went on the assumption that I have gone through exactly half a tank when the needle says 1/2 full, then im on my way to 28mpg on my first full tank

im assuming its actually 30 or so cause of the reserve tank though
but this is 100% city driving..in the bitter cold... and it already exceeds my accord's highway mileage

 

sport auto in L.A. getting 30 driving hard to 34 driving granny only got 3500 miles. what really pisses me off is the shift shock.

 

i drive 90 highway miles a day, 45 miles from 2700 altitude to sea level and then back up. my average is 35 mpg. but when i go down to l.a. and drive around, i get very close to 40 mpg highway.

 

my MPG just jumped to 35 mpg.. previously i was getting sub 30 mpg.


this is due to bit more Highway driving. may be finally through break in period (curretnly at 2700 miles)


i am sure this is just a feeling but that wierd sound (more like grinding sound from tranny) somewhat disappeared.

my fit shift somewhat "softer" than before...

but this is just my feeling...

 

4th tank of chevron regular 31 mpg 75%hwy miles. auto sport, 35 psi in the tires. I know it will get better.

 

Well I'm up to 34,000 miles (yes thats correct - and I got the car in Jun 06).
Still gettin a pretty consistant 27mpg with about 90% highway driving. Occasionally it jumps to 28 or drops to 25.5. Highest i have EVER gotten has been 31. Tires at 35 with Nitrogen fill, 1 person 75% of the time. Little idling, usually use the paddles. Lead size 13 foot 80-90 on fwy most times. Usually no AC or extra weight in the car except my 6'4" 360 frame

This about the same as my 97 DelSol S 5spd and my old 97 Civic DX Auto. Both with 1.6L SOHC non-VTec engines

 

You have been averaging 28 for 38K miles and do 90% freeway miles. Wow that can't be right. When is it schudled for a service visit to Honda I would take it in, and ask whats up??? I get that type of milage in stop and go and get about 32-34 when i go 75% highway, still others are getting 40+ doing the same thing. Still can't believe the difference.
