i have to go back through this thread and i have to read the part in my manual about setting the trip meter etc........but just in case i forget later

in one week my economy has gone from 11.4? (11.something) to 9.4
and i've used half a tank on 270 k's (petrol auto)

and she's done now 300 k's total!

Hey Snowcherry, if you can fill your tank to the very top, you get more k's from the tank full, that's why some quote more miles on one tank of fuel than others.
only problem doing this with petrol is fuel expands, like underground its cooler then goes into your tank, get's warmer and expands, if your on a trip and going to do say 200k or more that day, it's ok as you will use some of the fuel so no worries, but if your only doing short trips not good to fill right to the top. but my experience is. if you fill to the very top you can go a few hundred k's before the gauge moves off full. with the oiler diesels fuel does not expand as much so can fill right up no worries i go 300k before the gauge even moves off full, i did my 1,3?? tank full when the car was still low k's i think i averaged about 4.4 per 100, i seem to be able to get good economy easier now. but for me i always seem to get better economy new that other way around, as i drive them easy new then, drive them hard as they get older.
cheers

no i didn't get this
the day i got the car they filled it for me, and that first 270 k's on half a tank was from then.
my first "official" fill was when i was showing about 70 k's left in the tank on my trip thingy. as a round trip for me is about that and i didn't want to risk it, i filled up then. i filled as much as could, probably clicked off about 4 times. i can't recall exactly how much went in but over 40 and under 50 litres from memory. i still only got 280 k's out of half tank though.

edit: i guess you're saying i'm not going to see what it can give me until i can do a very long trip in one go?

mmm. I get about 350-400km for the first half and i usually do then extra 15-20km after the fuel light is on. My max on one tank is about 650km.

I also found that (on my) it takes a lot of clicks before it get full(starts around 40L). And seems that our tank is bigger then 53L because i fill up once and it reach to 55L and it still wasnt flowing out(my gf fill up).

interesting thats more the region i was expecting initially.  :neutral: 700 average is what i would love to have. 800 on long trips. but i'm barely scraping 600 though i'm still only on 2nd tank  :wink: :lol:

is there a 'safe' way to click off the bowser continually without having a backlash of petrol come out? bit annoying if i have to do it like that though.

is bigger then 53L because i fill up once and it reach to 55L and it still wasnt flowing out(my gf fill up).

well filled up today and took more notice, and it started clicking at 42L. kept going until 50L this time while last time i pretty much stopped once it started clicking so might have been about 44/45?. i have a hunch when it was filled for me originally the same thing may have happened. so possibly could have gone a bit more still as my petrol light had been on for about 50k's; but hopefully this tank will give more than the last two  :mrgreen:

---------------------------

on a side note i went back to Caltex and guess what? the premium i bought last time wasn't premium - it was 95!  :eek:
god i am SO mentally blonde at times  :-[
so i've had whatever was in there originally (probably 91) topped up with 98, then 95, now finally full tank of Shell 98.......*sigh*

Snowcherry...

I am not sure of the conditions you drive around in, but working as an admin assistant, I would assume there is some urban driving involved.

The Auto Petrol i30 hatch is rated at 10.3 lphk on the Aussie web site (and that's THEIR figures) in urban conditions (with the aircon off I would guess).
Using that as WORST case scenario, you couldn't get much more than about 500Ks from a full tank.

The combined (more likely real world) figures they quote are 7.6 lphk.
Using that figure, you would expect just under 700 (ish)....

Reset the trip meter's fuel consumption average next time you fill it, and tell us what the average usage is when it gets close to empty. Then we can see the sort of returns to expect.  It's all about the conditions.

My daughters manual SX is used in and around a country town, she is getting about 8 lphk on average.

Blue i live in a regional area, i drive from home to my workplace along the highway about an hour round trip. about 2 minutes urban there only. once or twice a week i go into town as well which is maybe half hour urban plus another hour highway.

i set my trip meter and economy meter yesterday actually on the fill.  :)

I guess I'm not doing too bad since I mostly drive in urban conditions...with & without the aircon on.

I read your posts and I can't belive  :eek: 600, 700, 800 km with 1 tank of gas  :eek: :eek: :eek:

I can't get 500 km with 1 tank (about 53 liters). My averege is about 480 km with 53 lit.

that is the auto figure for combined highway/urban? that seems optimistic i think
unless my car drops its economy as it settles in i just can't see how they got that on an auto petrol. on a manual petrol sure they would, but not an auto petrol. i'm just holding the 8.3 now, i think once i do a road trip i can get that down lower but it would not be a consistant ongoing average. anyway that 'should' land me in say 650 territory? which is still about 70 more than last two tanks.
interesting!

My driving is all in the city, and mostly in rushour  :'(

It is manual transmition with aircondition always on  :wink: so to me it is normal consumption of 11 lit /100 km.  :D

What's even more surprising is that if I drive EXTRA granny-like, I can manage about 6.2L/100km. But driving at 110-120km/h at 3000rpm kills it!

show off  :wink:

--------------------
last half tank was an improvement
305 kms.
this was making sure i had filled the tank.
filled up again yesterday having used about 580kms total but hadn't hit the red light yet so not bad!
so it appears i can get a guaranteed 600kms from a tank which gives me a sigh of a relief (unless i'm all urban for some reason). would still prefer 700 but it doesn't look like i'm going to get this, maybe on a road trip but not my local driving. 
all good :D

That's not bad Snowcherry, I'm on 9.8.. I wish I was a granny driver.  :lol:

I've tried to granny it a little bit (or at least sticking to the speed limit & not flooring it at lights) -  I'm now doing 8.4L/100km... :)
