Fuel Economy Per Tank Of Fuel

[HoZy]

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.

[sganro]

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

[vkberlina]

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
Scott

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.

300 - 600km / tank between city or highway driving, averages 400km in a mixed situation

[Joey_21]

13-14.5 per 100km full exhaust HF cat new leads plugs twin pods---thrash it round a lot though used 2 average round 15-16 b4 extractors came along

vr v6 5spd stock az,2 tonne wheels, and 1 tonne bodykit. bout 450 ks a tank more on the highway

vs wagon, 69lt fuel tank, last two tanks where on regular got 326 on 55 litres so that about 17l/100km around town, a little disapointed

[ssmate]

vs v8
75lt tank
bp ultimate always
400 - 450 kms to tank average

I'd be getting that checked out... unless you have been flogging the daylights out of it... but that seems way too high.

[shumway]

it looks like i have the worst economy of any vs ecotec around,yeah

[andyman]

yeah i know, im working on it, most of the time it dosnt make it past 2500rpm, im also putting it down to a few factors, 1 transmission is kindof rooted, and i have one of the dodgy memcals > should be getting my new one from dr bob during the week coming, im also going to replace a few sensors and buy a bottle of holden top end engine cleaner, btw i just reconditioned the injectors at tafe

I'd be checking the air filter and replacing the fuel filter whilst you are at it. Good luck getting the top end engine cleaner... Holden stopped selling it down here months ago, apparently their supplier doesn't make the product anymore! A substitute is the Subaru stuff, you spray it through the intake behind the throttle body, apparently its pretty good stuff.

[Bilbs]

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

m8, what type of car is it, a puegot 307? 5L/100K is not feasable for a holden, idd take another look at those figures.

But mine, VR 5.0L 5spd Ute Mostly std, HSV Chip, CAI, Extractors.
65L tank? regular unleaded, 590Kays to a tank on the highway, and about (i havent tested it) but i think about 4-450 around town if im not floggin it
So that is 10.66L/100K, 9.38 K/Liter and 26.51mpg

[thad 5l]

Just did a trip from gold coast to newcastle. VS 5.0L V8 Statesman. Trip computer says fuel average was 11.5l /100km. Running on 98 octane.

yeah everything is new + cold air intake, will see what i can find out at holden

[ThongyVL]

Had a VSII Acclaim, Cold air intake, K&N filter, 2.5 inch hiflow cat and exhaust (not sports exhaust), Changed memcal chip. 68 Litre tank best fuel economy I got in city driving was 550km.

On the highway I would expect allot more.

[immortality]

VS V6

59ltr tank, only mods are K&N (very dirty) and holden CAI. average 400-450km (91 octane) to a tank but thats mixed city highway but with lots off traffic. open road it gets 700 easy per tank. just cleaned the air filter so hopefully things will get a little better.

[buckna]

270-300km a tank. VRII v8 Calais

mild porting, injectors cleaned up, stage 2 cam, oversize pistons, lifters, rockers, extractors and exhaust, K&N filter and Holden CAI.

Goes fast but :P

[Drew4692]

VS V8 ute, 5sp, mild cam, roller rockers, K&N, 3.9 diff gears, tune
55L tank - 400 + klms per tank around town.
Not sure what highway klms would be, going down south on friday, will post then.

[ashbox]

VS calais v8
BP ulitmate
Cityave - 14ltre/100kms
Hwyave - 11ltre/100kms
75litre tank

[grnvs]

vs v6 5spd wagon usually 95RON pety

usualy bout 10L/100km
best ever 9L/100km (highway of course)
worst bout 11-11.5L/100km (that included towing a trailer for bout 100k's)

Its got CAI, k&N, 2.5in catback and sport chip
