Fuel Economy Per Tank Of Fuel

[yZoH]

Hey all...
Post whether you have a 6 or an 8 Fuel tank size & how many km's you get per tank of fuel & what octane you run..

Cheers
MaT

P.S- Will be posting in all sections to try to get ideas of fuel economies per model.

VS V6

Run regular unleaded most of the time (91 octane)

Fuel tank is said to be 59L

Around town - varies depending how how i drive but on average i would get 350km out of tank

On the highway - it would jump up to about 550-600 km from a tank

VR V6 5 speed
91 Octane Fuel - 10.6 around town has had a buggered set of leads which have now been replaced so im waiting for new figures.

Car has following mods
Mild cam
small amount of head porting
V8 throttle body
headers back exhaust

cheers

the fuel economy is 10 litres to a 100km round town and 5 litres on the highway running 98 Octane

HoZy if you are having fuel economy problems remove the injectors and have them flow rate tested.
The reason I say this I've done a Ecotec transplant into my Vr Ute and when I first fired it up three injectors were part blocked, after cleaning and flow tested they were OK and the open road economy was 10ltrs/100km.
Just on 12 months later while doing some work on the headers I noticed the left bank plugs were dark and the right bank were leaner, checked the codes (Vs ECU) and I had "76" Shot Term Fuel Trim unbalance. I had the injectors tested and the 5th cylinder was 25% lean, so the o2 sensor reads this as a lean average and pumps more fuel to the left bank.
None of this problem brings up an ECU light.

I've since replaced all the injectors with new ones as I've found the 0280155777's used in the later Ecotecs don't take to cleaning very well, now the open road economy is 8ltrs/100km.
