Well when I set up my account, I input "gas" as I drive a 1.6 petrol. I have also compared the same the old fashioned way with a calculator and the figures match  :D

Mine is on 16000km now and the lowest I could get it driving very lightfooted is 8.0l/100km. I was wondering if it could be because of the sparkplug gap, but i'm not sure how to get to the plugs and what the gaps should be as it's not in the owners manual. Help please

Welcome hannes.. is yours a manual or an auto? I doubt the sparkplug gap would be the cause  :eek:

also depends where you're driving. a lot of start/stop inner city driving, or motor ways/highway driving? you won't get very good ratio's on inner city driving with the petrol. i average 8.4 up to 8.8 for highway driving in a petrol auto. i have managed to get it into the 7.0's but only in extremely long flat runs on the highway.

Car tells you 8,6 lt/100km but was 9,6 in reallity. That is, you paid for ~4 litres more (per every fill-up after 400km).
Either:
a) you filled up to the neck, but the car still considers that as 53 litres (max tank capacity)
or
b) (unlikely) gas station's fuel pump is a really big cheater (+10%) :eek:

Reset trip computer and next time pull out the hose immediately after the 1st click.

well i do keep filling after the first click but my first click comes at only around 40 odd L's. even filling to the neck i can struggle to get over 50L in there. this fill was 56L i think though as i was running on empty.

fuelly says that if you like to fill to the neck make sure you do it for every fill. so i assumed by this fourth fill it would now be averaging out, but it still says 9.6. (it started at 10.something).

oh i think i get ya now i wrote that out and read it back, you're saying i need less fuel in the car for the car to do a proper reading. bugger    :-\

Hi SC,

I don't believe the Trip PC would be that much out (.1 or .2 maybe but no more than that.. So I suspect it has something to do with Imperial Gallons Versus US gallons... :whistler:

Publish your kilometres versus litres purchased and we will soon give you an accurate figure  :goodjob:

hmmm i think anyone can see this?

http://www.fuelly.com/driver/snowcherry/i30

Have you still got your original Kilometre and litres purchased figures?

I'm concerned that calculator is using US gallons which are different to what we use..

See here:-

 :eek: you sure did run on empty!
I'm not sure how many litres can get into the "neck", but I know that my brother's '02 Seat Leon takes up to 10ltrs there!
As for MPG, gallons etc, sorry but i've "lost the ball" :confused: :lol:
  • 1.4 HB Classic '09 White

Yeah, gallons ain't gallons... but a calculation from full-tank to full-tank is simple enough to verify. The only thing you need do is ensure the tank filling is exactly the same for both fills. The guaranteed way is to neck it both times. Relying on "first click" or some other indicator can be a variable.

I really can't believe the figures you have are correct. :wtf:

yup i fill to the neck on every fill. i find the first click is no good as that tends to occur at only 40oddL for me - also many bowsers up here tend to be set too sensitive and click off easily so a 'true' first click is about impossible to determine. so i find it easier to always go the neck.

I always refuel from a specific(*) gas station and pull the hose out by the first click. Found out that figures between trip computer and my calculations are pretty much the same, as Dazz said.
So, you don't trust your Trip comp. or your gas station?

well i guess i don't trust the first click regardless. seems pointless to me to only fill it with say 42L

i don't always use the same petrol station. some days i drive south, some days i drive north. with almost two hours between towns it's a big ask to keep to one station.

i'll keep doing by the neck but there is a discrepancy there between the car and the onsite thingys. i guess i just have to settle with the fact that my economy is much worse than i thought  :confused:

Even if it costs a little more fuel. Besides, my humble 1.4 "drinks" more.

teehee i'm not sure we call it freedom here, more of a lack of choice living in the 'sticks'  :lol:
work is one way, groceries are another way and anything remotely resembling shopping is the other way

Maybe Marathon running isn't an Athen's only "privilege".
I always try to find groceries and shops alongside my way back home from work (the benefits of living in over-populated places)

well my fuelly and gauge don't add up again - but this time in reverse  :rolleyes:
fuelly marvelously dropped from that 9.6 to a lovely 8.3! but the gauge had gone from the 8.6 to 8.8.  :rofl:

this last tank gave me 630 kilometres though so i guess that is why fuelly dropped so much. i guess as time goes on fuelly will just start to level out.  :)


http://www.fuelly.com/driver/akamikazebutterfly/i30


p.s the 8.3 is 28.3mpg according to fuelly.

Hello all! I am happy to be posting numbers for my "petrol" i30. I have been averaging 33 US MPG which I believe converts to about 7.1 l/100km. I have removed my back seat. But added at least two hundred pounds of equipment to the vehicle. The car is a 5 speed.

that's not to bad considering all that extra weight your carrying around.
