Thanks alot aaronng, i understand what your saying now...i usually do accelerate very lightly especially at the start when u leave at a green light. sometimes you can accidently push a lil more force and the car just moves of really fast. I always avoid that.
I think from now on ill only use Vortex98..i usually do but the petrol station near by doesnt have it everyday...so i miss out alot.
You can learn a lot about how to get good fuel economy by watching how GOOD heavy truck drivers drive.
Get off the power early when approacing red lights - try not to have to stop
Light application of power before the you start going up hills (on the approaching flat) - as distinct from waiting until you have started slowing down and then giving it extra throttle to get back up to speed.
Back off at the top of the hill, not when you have allready gained extra speed.
Change lanes when approaching a slower vehicle instead of getting behind the vehicle, slowing down, changing lanes and then having to accelerate.
Drive at a constant speed (when traffic conditions allow) instead of gradually speeding up, realising that you are going faster than you have intended, slowing down, and then repeating the cycle.
wow thanks for the info, looks like i gotta improve my driving by a fair bit. Its sometimes hard to accelerate slowly so it doesnt just move fast (giving that jerky movement -->which i think is what u call throttle)...but i gotta be real light with it.
I drove just then and accelerated very slowly...like not going past 2500rpm...its hard not to go over...but im gettin use to it...
lol, thanks for the driving lessons :D
i filled up yesterday on ultimate.....the pump said i filled up 48.88L....which mustve meant i had 17L left to go until i was completely empty
i filled up after travelling 517kms.....with 17L left in the tank .....is that good for city driving?
btw, how do u guys measure how much petrol u use by doin that 9L/100km thing? how do u measure ?
I think my post at the bottom of page 7 of this thread covers what you are asking.Quote:

Distance travelled 517km, fuel used 48.88 litres. 517/48.88 = 10.58 k/l. To convert k/l to litre per 100/km = 100/10.58 = 9.45 l/100 km.
As per my earlier comment, this calc is only valid if you have filled up to the same level on both occasions. A one litre difference in the fills results in a difference of about 0.2 l/100km in the calcs.
You need to fill up to full tank once. Drive until the next time you need to refill and go back to that same station. If possible the same pump.
I've tried 2 stations, 1 shell and 1 caltex, and the difference in filling can be up to 5 litres. I have to keep pressing the pump trigger at shell station until it fills to the top where I can see that petrol comes out of the 1-way flap and then slowly flow back in. At the Caltex the pump only stops when it is filled all the way out of the 1-way flap and the petrol flows back in slowly.
So in my case, the caltex station fills more than the shell station that I use by up to 5 litres.

Car has factory trip computer that records fuel consumption and journals it to the dates between fills, it gives you instantaneous and average fuel consumption at any one time and distance left in the tank.
First tank of fuel the car said it had 660kms in the tank. Travelled 560kms the average fuel consumption was 11.5km/L and the car said there was just over 100kms left to go. This was on 91 octane (straight off the dealers floor).
Refilled with 98, same driving style and fuel consumption is way down at 9.5km/L. This is no A/C driving.
I wouldn't trust what the trip computer says 100%.
The most accurate way is to fill it up, reset your tripmeter and then see how much petrol you have to put in to fill it up the next time.
Got 8.9L/100km from my last tank. I used to get around 8.5L/100km and even less sometimes, but it's been creeping up lately. It must be because the car's due for a service in the next 1000km or so.
More fuel = more weight ;)
Man isn't petrol expensive these days! it costed me $70 to fill her up!! gotta watch out the heavy leaded foot!
$70? :eek:
My civic usually cost half that!
