Oooh! I got 5.9L/100km over the last fill

woooo go duckman!
may i ask what your driving conditions are? flat, hills, use cruise or not, average speeds etc etc?
yeah i'm nosey

me too

I did get 6.7L/100km taking the motorway (90km/hr) late last night.

snowcherry · **Reply #212: October 17, 2009, 08:18:04**

wow! good one dijana!

the 10kms makes a huge difference hey? if i tried driving 90k's round here on the highway i'd probably be drawn and quartered (well gestured very rudely at)

sweetbix · **Reply #213: October 17, 2009, 09:08:22**

Tracey, that's not to say I was doing 90km/hr the whole time. But I tried to keep it between 2000 to 3000 rpm...and that seemed to help a lot!

Ok, well it's mostly motorways in the morning (M5 into Sydney). However there is heavy traffic early in the morning, average speed about 40-50km/h. Flat roads, no cruise.

On the way home I travel the M4 and M7, flat mostly, the M7 has a few slight hills. Average speeds about 90km/h until close to home, then it's a crawl. Cruise some days depending on traffic.

oh duckman i just realised you have a manual

that will do better than the auto
but its still very impressive

i reset my trip thingy again today and it dropped to 7.0 by the time i got home!
thing is it seems i reset it and it does drop a lot but then it goes up again, next time i reset it it will drop again but more than it did previously then start to rise again. its like alice in wonderland! i'll probably be in high 7's again tomorrow.

Duckman · **Reply #216: October 20, 2009, 05:41:28**

Heh, it is fairly inaccurate over a few hundred kms after a reset. I first reset mine after it's run-in period (about 1000km or first service), and didn't touch it until 25,000 km. It read 7.2L/100km, which is dead on the average they give the manual for a combined city/country consumption.

I reset at 25,000km and it's reading 6.7L/100km, after about 1500km.

snowcherry · **Reply #217: October 21, 2009, 00:57:52**

haha i'm button happy, i've been resetting each tank fill

well my prediction was correct and my 7.0 jumped straight to 8.0 within barely 1km of leaving home yesterday. but get this, i was running a wee bit late for work, was a wee bit cranky about the ecenomy gauge and just thought stuff it i'm not babying you anymore! so yes after a return trip to work and back over hill over dale not driving as well as one should..ahem...it was still 8.0!

Duckman · **Reply #218: October 21, 2009, 06:11:44**

Haha, well there's a surprise!

I highly suggested monitoring your consumption yourself. I had an iPhone application (RoadTrip) and it once said my lowest consumption was 5.6L/100km, over a 700km tank full of petrol. You CAN fudge the results by filling up to almost overflow point, then once you need fuel again, fill it unti lit clicks once or twice, then record results... No I *didn't* do this though

snowcherry · **Reply #219: October 26, 2009, 21:45:43**

i'm starting to wonder if my little economy reader is a bit whacked out with it not budging from 8.2 all week whether i'm driving at 60 or 110.

anyway aside from the head scratching there, i am quite please to say i have sailed past 600 km's for this tank.
i'm sitting on about 630 k's, fuel light came on about 10 k's ago and says i have about 60 k's left.

so pushing 700 for this tank. with a mix of driving and not much babying at all. i'm really pleased with that

Hey! What you get up to in your motor is your own business

Hemmi · **Reply #221: November 13, 2009, 19:27:13**

got 700km and decided to fill up.

The "distance to empty" meter started blinking in about 680km, anyone know how much is left when it stars blinking?
I think it's about 50km.

I'm happy with the result, I did not drive economically, usually reeving high and all city driving.

2i30s · **Reply #222: November 13, 2009, 20:39:40**

is 530kms on 1/3 of a tank good

we took both cars from Hampton park to sheperton and back in 38deg/c temp with aircon on and 4 people in each car at 110kmh,I'm happy.

If the rest of the thirds would be the same, yes, but they are not

If you know what I mean

2i30s · **Reply #224: November 14, 2009, 00:43:28**

yes unfortunately,the top half holds more than the bottom half.

So logic would say:

If half full there is less than if half empty

2i30s · **Reply #226: November 14, 2009, 13:32:54**

dead right.

snowcherry · **Reply #227: November 21, 2009, 07:32:00**

my economy is depressing
i worked it out manually today and it was 9.0 over last tank
the car says 8.6 currently

checked tyres today and the fronts a little low on 34 (backs 36)
i do my 800km drive tomorrow so have pumped up tyres and have fresh tank

will reset meter and see how i go
i'm no hoon - and highway driveway with some hills and rare urban, i just don't think i should be getting that. still under 4000k's. engine also revving wee bit high which maybe using some fuel up. ??

i know it could all be a lot worse and it should get better in time, but i had the 7.6 in the back of my head when buying, so still a feel bit grumbly about this.

i30Dave · **Reply #228: November 22, 2009, 11:26:46**

With my SR (auto) the best i've got is 7.2 This was from driving so smoothly (boring)
and keeping revs to under 2500. The factory stated ltrs/100km are bullshit.
You can only achieve these by driving like a old person. So if you can get around
8ltrs/100km from your car your doing well.

sweetbix · **Reply #229: November 23, 2009, 07:15:12**

Snowcherry, you're doing better than me.. I'm back to 9.4.

Duckman · **Reply #230: November 23, 2009, 07:40:27**

Still running at 7.1L/100km (manual though, and mostly highways)!!

SergeyZdravkov · **Reply #231: November 25, 2009, 20:56:38**

Guys, you surprised me.
In city conditions (short trips, cold engine) i've got between 8.0 - 10.5/100 km depending on how cold it is. 1.4 L engine "loves" temps over 18C.
On long trips (country roads mostly) I've got 6.2 - 6.8/100 km. normal driving - 6.2/100; more aggressive driving - 6.8-7.2/100

average - 7.7/100

**Reply #232: November 25, 2009, 21:06:45**

The last 3 tankfuls I've done an average of 600+ per tank which for the amount of city driving I do is pretty good for me. Considering my wife's car has a bigger tank, a smaller engine size (1.6L) and can only manage to eek out 450km max I'm happy with my economy (though she's quite upset hehe).

highandnotdry · **Reply #233: December 07, 2009, 20:33:17**

Petrol 1.4 Comfort. First tank of petrol registered 37 mpg on the trip computer (which surprisingly matched up with my calculations after filling the tank again). Driving was nearly all start and stop in to work and back (4.5 miles each way with lots of traffic lights and roundabouts) so I'm quite happy with the figures.

thanks for the input dave
and dijana sad to see you've dropped back to
-----------

well i had my brissy run.
reset the trip and eco thingy. and did not budge under 8.0 for most of it. i was quite gropable as i was having a beautiful drive and it should have been dropping overall. then after coming out of a area where you jump from a slow 90 to a fast 110 i expected then that the economy would go up again but it didn't. so out of curiousity i reset it again, and it dropped, it really dropped!it was like as i've previously believed it has done, got stuck. so my 8,s went all the way down to 6,s. well knock me over with a feather. by the time i got into brissy i was low 7's. i spiked at 10 while city driving but averaged around 8-9. finally coming home trip averaged 7.5 just pushing up to 7.6 as i neared home....finally the magic 7.6.
of course since i've been home i'm weirdly back into 8,s again. damn!

tanks - best tank i think i might have been pushing the 800. if it hadn't been for the city driving i might have got past that i think.

Undertaking a decent run from Sydney to Merimbula (far south NSW coast). Hopefully will be recording a new low fuel consumption average. Planning to go through Goulburn, Canberra, Cooma, then heading to the coast.

Make sure if you see a black i30, you give me a wave!!

**Reply #236: December 15, 2009, 02:44:48**

In October, I tried an experiment and filled the car completely and then drove on the highway until it stopped.

At 725km, the light came on and the estimated range fell under 50k. It ran dry at 795km, mostly highways and about 60 minutes of stop-and-go traffic in Montreal. Consumption: 6.7l/100km. I'm pretty sure I can reach 850km if there is no traffic.

ALso, when I filled it then, it toook more than 53L to fill up, something like 57L. What's the top quantity your cars took when really thirsty?

yes i've hit 57.4 i think at the most...and i've got pretty near the 57 a couple other times to. its timely getting there, bowser clicks off a lot in the meantime.

Got back from my trip, 1300km round trip including local driving around town and miscellaneous other drives, on 2 tanks. The litres per 100km never moved off 7.1km/100km, however the economy was fantastic, even though I was sitting on 100-110km/h most of the way, at almost 3000rpm at 110km/h.
