Jazz Fuel usesage dometer

[vupham]

Hi guys, does your fuel useage dometer (Ltr/100km) goes up and down depends on your driving condition? Does it changes often or very slowly and whats the average on yours? Just bought the jazz so i dont know how it works, mine started at 10.9ltr/100km and currently staying 7.9ltr/100km. It changes very slowly, not consistant like the ones in the BMW 3 series, just wondering is this normal?

Normal.....

[vividjazz]

Take the number of kilometers you've done and divide it by how much fuel you fill up with and you'll find its a lot more accurate. The longer you leave the dometer without reseting it the more accurate it can become because it makes the calculation based on a greater distance / average.

To show how inaccurate it is fill up you car, reset it and then sit stationary with the engine running for 5 minutes and watch the number keep going up. Mine went up over 20ltr/100km putting a 6ltr V8 to shame.

Feul consumption depends on the condition that you drive your honda Jazz. Based on my driving condition in Thailand, the normal rate was 13.8 to 14.5 km/L (Driving in Bangkok, half of Toll way and normal road facing some part of traffic jam and didnt kick down or use 7 speeds mode. Drive at 90 km/h).

Another case, I drove to other city around 300km from Bangkok (capital city of Thailand) the fuel consumption was around 11.9- 12.5 km/L at speed around 120km/h sometime increase to 140km/h.

I think Honda Jazz is tend to save fuel when you use in the city at speed not over 100km/h but the rate tend to decrease when you drive over 120km/h cause REV tend to rev higher than other car when drive at the same speed.

woah... your jazz drinks lots of petrol...

My car does 9.3L/100KM on my everyday ride, from home to work and to the city sometimes... But when driving up to the country side, it'll do 7.4L/100KM (staying on 5th gear) oh forgot to mention I tend to keep the RPM at over 3000RPM :)
My car only done 25000KM on the dot... at the moment running on 15" with not that many mods- header, extractor, pulley, intake and exhaust... But I was comparing with a friend's of mine, his' one doing 7.6L/100KM on everyday ride... Same mods but he dont have the pulley though he have a bpipe... :(

But anyway... the Jazz definitely cheaper to run than my civic and the R8 :D

[clem]

What the hell? I thought the rated fuel consumption for these cars were like 6L/100k or something? Whats with people getting 7-9? Thats pretty abnormal unless ur thrashing ur car. With my civic i get about 6.6L/100 on average if i drive economic and they rated it 7.3L/100

[AmateurJazz]

When I did my own calculations my jazz had a mileage of 6.6 - 6.8L /100km.

lol thats what you get for being a drag slut haha jk :wave:

i never get past 7.4 and i got the same mods as you + bpipe
i average 6.5 most of the time, must be my smooth driving :cool:

[UBH320]

Yeah... not to mention I have my full audio system + my heavy foot... ptech all the way from home to work LOL... just last night managed to get down to 8.0L/100KM after a lap to Mt Danddy hahaha - was running 100RON though...

Last week I also did managed to get 490KM out of the full tank... I wasnt being a drag slut...

[vtec-NA.th]

I'm getting around 7.0/100km

I haven't been for my 1000km service yet though.. goin in this week haha XD

[Tofu]

the fuel usage meter in the Jazz gives an average...
the system on the BMW has two functions...
one is an active reading, depending on how much you step on the throttle, and there's also an average reading.

im guessing most of u have aftermarket rims or something

stock steelies with vti, gets about 6.2 - 6.5 or something.


bigger rims will make a BIG diff. BIG! especially with a low torque car like the jazz.

[SassyV]

wow... some of those figures are kinda high, are those with mods on ur jazzes?
I have a stock jazz thus far and usually get low 6's and that's pretty constant.

16' but light weight rims + audio systems... I manage to get it down to 8s/100KM... after a lap to Mt Dandy hehe...

Also with the mods you do to the car will affects the fuel consumption too!

[Penguin]

lolz....i average around 8l/100km...with a few modest mods

[vtec-NA.th]

mine's on 7.7 now.. :(

i got super light weight rims and tein sussy. hope it goes down.. lol

[Jazzle]

from my experiences with the jazzes, the fuel meter isn't all that accurate, if you try to do some maths everytime after you fill up the tank, u will see the figure is different..

[zco]

my gf's jazz gets about 6.7L/100kms
i once got it as low as 5.6

[asdetail]

my wifes jazz vti manual consistently gets around 5.8-5.9l\100klm u guys are all leadfoots i presume:rolleyes:

Not so.

Fuel consumption varies due to many differing situations. They are, but not limited to:

1. Number of Kilometers/miles travelled
2. Driving conditions eg
2a Very short runs less that 10 km
2b Long runs more than 10 km but not long distance driving
2c Long distance runs travelling at about 100 km/h
2d Long distance runs travelling 110 plus
3. Type of fuel used
4. Tyre pressure AND condition and type of tyres
5. Ambient air temperature and humidity
6. Altitude
7. Servicing (tuning)
8. Type of transmission - 1.3 manual/auto, 1.5 manual/auto CVT
9. Modifications that affect aerodynamics and/or change engine performance
10. AND MOST IMPORTANTLY, HOW THE CAR IS DRIVEN and THE LOAD CARRIED

So as you can see, to claim a low or high fuel OK, but maybe you need to state the above conditions when claiming great fuel consumption or bemoaning poor consumption.

For me, a CVT 1.5 auto, with nearly 5000 km done and the 1000 service, and only using Shell unleaded fuel. I am getting about 9.0 around the city <10 km per trip but about 6.3 on a long trip travelling at about 100 km/h and slowing down for towns.

The only variation to the 1000 service, I insisted and paid for a change of engine oil.

[VT1-R]

stock vti.. 6.8-7.0litre/100km... 75% freeway 25% 60 zone everyday..

[fundies]

I'm just about to get rid of my 16 inch rims with 195 wide tyres, and go back to the standard 14 steely rims for my VTI. Fuel use for me with the bigger wheels/tyres, 7.1 l/100km's, or 6.3l/100km's with the steelies, and much more comfy ride. Maybe I'll just get some nice 14 or 15 inch lightweight alloys to replace the steelies, I think 16's are a tad too big for the Jazz.
