What fuel economy do you get on your V6?

[Shortstuff]

I've just filled my petrol tank, driven almost exactly 100km then re-filled the tank. It took 15.9 litres. I have done all local driving with no journey more than 15km. Is this about normal? What are other people getting from their V6's on local driving?

i got 15 almost exactly last week. went into the petty station with 398 from a full tank of 60l.

[Shortstuff]

15.9l/100km isn't too bad then? I think I may have a couple of sticky injectors as the car is really lumpy at idle but runs much smoother as soon as I give it a bit of throttle.

I have gotten from my last 3 tanks..
455km-478km-430km. Fill up with about 66-67 litres.
Thats an average of 14.5l/100 I'm happy with that.
I'm a local driver the only time i get on the freeway is for 5min to go to the shopping centre at Airport west.

I get 13litres/100 km if i drive it normaly but since im a Young P plater i tend to floor it a lot so i use more. And if its raining my fuel bill increases by 30%. funny that

[1991_Vn2nV]

About 15.5L per 100km..

[sircruisealotVS]

completely irrelevant due to difference in engine...but my ecotec stroker gets 12L/100k's....food for thought.

[Shortstuff]

I might have to sort the injectors and then see what I get! I was surprised it was as high as it was since I drive pretty carefully.

Whats my excuse I'm 30

Around town I normally get about 11.5L/100km on the open road I normally get about 9L/100km, I have had it as low as 7.5L/100km.

Doing time trials on a mountain road in the Victorian Alps I did get it out to 17L/100km.

It's a manual though, so that helps a bit.

[fitzy2005]

around town i get 11.5lt/100km highway i get around 7-8lt/100km
got a vr exec v6 auto with extractors 2 1/2" exhaust cold air intake and a chip

[covert77]

my best is 14l/100km and worst is 20l/100km. but i don't care what my mates say about having a small chicks car for cheap fuel consumption, i prefer my beast!

I have a VT stock 6, driven back from Adelaide today and I got over 700km per tank. Only filled it up 3 times and still got half a tank left

I was running it on 92 octane bloody fuel prices was $1.45 a litre. I was sitting on 2k rpm just crusing at 100kmp/h - 110kmp/h. Overtaking at 3k rpm at 120km/p. With 1 passenger and 1 big tool box in the boot.

[PaRaDoX]

yeah maniac, you'll find long journies are very ecconomical,

i got 768km / 50L when i went to NSW and back.... cruize control sitting on just under 2000 rpm (1900rpm)

around town im lucky to get 350km/55L
computer says i get 16-16.5L/100km
but then again i drive 30 mins in peak hour traffic twice a day... lots of stopping and starting, then flooring it to make a gap.... especially when the engines not lubricated properly, if its not in operating temp it will be a chugger on fuel

converting to LPG in 2-3 weeks so im not too fussed

That is something that confuses me, The VT is better with the ecotec on fuel over a Buick V6 VN-VP-VR. But your 100kp/h rpm @ 2000rpm is more then what i would sit at, And that confuses me to why the Buick V6 wasn't as good on the highways?. @ 100kp/h i sit @ 1700-1800rpm.

[coolvxss]

My vn 5sp manual sits on 1900rpm at 100.

I have been told that engines are most fuel economic at the point where they produce most torque. I suppose it's because it requires least effort if you have to accelerate at that point.

If you drive a manual at 40kph in 5th gear, you will get worse fuel economy than if you were doing the same speed in 3rd.

To accelerate at the same rate, you would also have to put your foot down a lot harder if you were in 5th rather than 3rd. I reckon that's also what makes the fuel economy worse.

Does that make any sense or am I gibbering?

Your saying because a 5 speed in in 5th @ 45kp/h is only labouring the car, When in a lower gear with more revs it's going easier on it
hows that

Thats the one! My brain has gone to sleep before the rest of me

I only knew what you were saying cause my SH nephew was driving his mums 5 speed proton @ 35-45kp/h in 5th gear thinking it would save petrol, When he looked at the Trip it was going up and up, So i said to him don't go into 5th unless your going over 60kp/h or even 70+.
He then went back to 4th and the fuel started to drop slowly. But he never learnt still

[Shortstuff]

We used to do it deliberately in company cars that had a trip computer to see how bad we could get the economy if we went on a bit of a drive!

I'm a bit more watchful of my fuel economy than I used to be, coming from my old 1.8 litre manual VW Golf to the VN!

[Full Spectrum]

It's the times that make us think before we stick the foot down now
I must admit to not carrying anymore on fuel since i was using 27l/100km to now 14.5l/100, You can see how I'm really not worried now
But soon i might start to worry if it goes any higher

[Shortstuff]

Yeah, if the price goes too much higher I may need a VN SS with a gas conversion

How did you get 27l/100km? Thats some harsh fuel consumption!

[88GreenVN]

VN V6 wagon getting 11/100 now that I've replaced all the sensors (was 15/100)
The VN V8 on a trip tp Pt Pirie got 11.2/100 and 15-16/100 around town

[coolvxss]

I recon its not realy how many revs your doing. Its how much your putting the accelerator down.
