You mean like Newcastle <-> Canberra, Newcastle <-> Muswellbrook?
:-)
I do a few country km but not all. Yes, the economy does come down
to around 650km per tank around town.

Where did I say that I had a V8? :-) I have an AU2 dedicated LPG
wagon. That's the factory built LPG 6-cyl with the same rated power
as the petrol 6, unlike the BA where the LPG engine has less power
than the petrol.

you have to be careful here , remember fuel burnt = energy and lets be
honest yes some of the newer v8 are heavy but leave the falcadore and
suddenly you have a small v8 car eg certain EU and jap brands.. which
come with 4 6 or 8 pots...

Oh ... because you were comapring your LPG AU2's fuel-consumption to his
mate's V8 petrol BA's fuel-consumption, I automatically assumed you had
a V8.
[Actually, truth be known I assumed you missed the V8 bit in his post,
and decided to be facetious :) ]

Hey mate into perspective here, sorry to disagree with you however what part
of a Suberu Imprezza WRX is either a V8 or a V6 as the tittle says?

The topic changed from the title; such things often happen on usenet.
If you want to go back to the original topic, & the post that started
this thread, then you're right; the V6 cars currently on the market
appear to be just as low-quality as the V8 ones that're available at a
similar price.

A mate has a factory duel fuel AU11 and has had no problems with it but
the mates son who is the workshop manager at a large Ford dealership
told me to stay away from the dedicated gas Falcons.
He said if a Falcon comes in a tow truck most times it will be a
dedicated gas car and usually the problems are not lack of gas.
I was quite surprised by his comments which he made after I told him I
was looking at getting one a while ago.

no not "per cylinder" when you're measuring pumping losses in terms of
fuel used can you argue with the fuel molecules "hey listen in know
there's a lot of losses here but can't we work something out on a
per-cylinder basis?"
it's the total work, which is delta-pressure x delta-volume (graham
can confirm whether i've got this right again...) and that will go up
with:
1. overall swept volume
2. compression ratio

no it's not. you need to do more work pumping that stuff around a
bigger engine

previous v8s. this is well-known, it's an oversquare motor (from
memory), it's not that torquey.

That is not quite correct, while compression is mostly adiabatic, there
is a greater energy loss to block and coolant with more cylinders. OTOH
a single cylinder 5 litre engine might be a PITA to drive.
With more cylinders, the potential for a "show stopper" increases
simply because of more moving parts (irrespective of the load on them).
This is all a reason why large ship diesels contain only a small number
of cylinders.

Speaking of gas what happen to Hatz to praise the hell out of Tickford
LPG set ups. :-)

it depends if you're talking peak horsepower or that required to
complete everyday driving.
two examples are:
VZ Monaro, 260 kW man., 1700 kg, 14 L/100 km (ADR)
EVO8, 195 kW man, 1470 kg, 10 L/100 km (ADR)

Interesting that the EVO has more weight /kW to drag around and still
gets much better consumption.
Oz1...of the 3 twins.

That's because of Mr Turbo.
Add in the fact that you'd be nuts to involve WOT in any way regularly
with one of those devices, and there you have it.

define small ?
size with in design limits brings certain efficiency doesnt it ?
eg 253 holden vs 308 heads on the 308 works much better with a large
bore .
so which would be better ?
5.4 litre v8 or a 4 cylinder of the capacity

So your saying Toyota and Mitsu and Nissan are not made in japan
