2006 VZ SS 6.0 Litre - Gas conversion?

[CDC911]

Hi Guys,

I have recently acquired a 2006 VZ SS 6.0 Litre and as such have joined this group so that I can learn from your experience.

I might be posting a dumb question here but nevertheless, the question is... Now the petrol is getting out of control, do you think converting my newly acquired toy to an LPG is a sensible thing or more of duh?!. I'd like to enjoy my car but if petrol is too much, I will be restricted in enjoying it.

I am awaiting from your expert opinions.


Regards,

CDC911

Welcome...

I would say that the majority in here would be of a similar opinion..

If fuel use is your primary concern.. then mabe the 6.0lt Holden is not the car for you.

IMO.. 6.0lt Holden engine on gas is a waste..:burnout:

Hey CDC911, I know what you're talking about. I just picked up mine yesterday and I gave it some thought. I'm holding off with the conversion to see how things go with the price of petrol and LPG. I converted my last car when the price of LPG was 40 cents. It's now b/w 50 and 60 cents. Also hold off converting allowing time for the systems to be improved to run on the 6.0L. I know one place has recently converted a VZ 6.0L Clubsport.

Do a search.... use gas or conversion as your keywords.. its an ongoing topic here now...

and like was said above.. if petrol price is your concern.. maybe the 6lt isnt the car for you..

I've just bought a Corolla and find that it's gutless. Do you think that it's a waste of money to fit an LS1 to it for a bit of performance....I find that it will hardly even chirp the tyres in 1st....:errr: :burnout: :driving:

[Tombo]

I love my 6.0lt. I reckon that the sheer joy of driving it is worth every cent. Sure petrol is getting a little more pricey but i'd rather buy a bit more petrol than drive around in a pokey small economic car. I guess that's why I have always had V8's. BTW gas does not interest me as I think it will soon catch up in price if the pollies can see that they can make a few quid out of it...

Cheers

Welcome CDC911,

I have owned my SS Thunder for about 5 weeks now. The fuel consumption is actually quite good. My previous car was a 99 honda civic and it averaged about 7-8 lts/100. The new ute is averaging roughly 9-10lts/100. 80% highway 20% city driving. Mind you i don't drive it too silly. I must admit with the first tank that the dealer payed for i only got 350km. I was giving it heaps tho!!!!. But i think if you drive your new toy sensibily you will find it will be good on the fuel especially if you do a lot of highway driving. Good luck with the new toy. You will love it!!!!!!1

[loudvtss]

I agree with Tombo. The pollies will get people running on LPG and then increase the price of LPG. The pollies don't give money away without intending on getting it back. The perfect example is 'First Buyers Home Grant'. They give you a grant but you then pay 2 - 3 times that back in stamp duty, land tax, tax and other taxes. So in fact they've recouped 2 - 3 times the money back..

[CDC911]

Guys,

Thanks for your feedback. It was very much appreciated. Now it gives me clear direction. 6.0 litre is the way to go. In my mind, I really wasn't gonna convert to LPG. I am a purist as well.


Cheers!

well so far that lpg thread for injected gas is saying same power or more in some cases as petrol, so maybe not a bad option.

has to be injected gas, which is more expensive to install, depends how high petrol goes as to how long it would take to get the money back for gas instal.

9-10lts/100.....I keep reading this on here, and I can't see how its possible. Mine averages about 14-16lts/100 and I wouldn't say I drive it very hard all the time. I don't understand how anyone could possibly have a average that low, mine has never even reached 9L on a long highway drive.....Oh well, as has been said, if you are worried about fuel 6L V8 shouldn't be in your garage.....It doesn't bother me at all really.

congrats on joining the 6.0L club.....get some pics up!

depends on where you live, in sydney alot of people travel some long hours to work, mainly on hwy's then enter the city and stop...

[CDC911]

How do I publish my car photos? I have searching as to how but couldn't figure it out. Help!!!

My cam only car has been averaging 15.6 lts/100 at av speed of 62km/h,now for some time.

As for 9's on a highway trip, I managed 8.4 on the trip from Cranbourne to Shepparton. Door to door from G&D to my house Av speed 101km/h. All 274rwkw's worth.
From Cranbourne to the tunnel at Punt road I was sitting on 7.8. Rang G&D and told Matt he'd totally rooted my fuel economy when I got home, he just laughed.

[GETUTED]

When looking at L/100 comparisons, avg speed also need to be compared. City driving for one person might mean avg speed of 45, whereas for me its around 30. With an avg speed of 30 I get around 27L/100. That drops dramatically as the avg speed increases.

I've found that my LPG-converted 5.0L AU basically gets about the same dollar value as my VY1 SV8 for fuel consumption. I fill the AU up with LPG about four times in 2weeks at say $25/tank (small tank), and the SV8 about 1.5 times $70/tank (never empty). I *KNOW* the AU was a lot thirstier on petrol than the SV8 so the LPG conversion made sense for it (and I already owned it). However, if I was looking for a replacement I'd seriously be looking at buying just a petrol-only GenIII/IV "something" ..

After driving the two side-by-side for almost a year (mostly hwy miles) I'm very impressed with the economy of the GenIII. As it stands I wouldn't bother converting it to LPG unless you drive a lot, and most of that driving is in built up areas.

My two cents ..

[Aus8]

I have the best soltion. Instead of spending the $$$$ on Gas conversion get it L76 Edited. When is the government going to offer rebates on LS1/LS2/L76/L98 edits!??

you best bet would be to crush the ugly sod and sell it for scrap metal.

Get a better looking 4cylinder... (if there is such a thing), and throw a LS1 in that!

[SSV8pilot]

CDC911 - another option may be a chip/tune. I don't know much about them but it may be that a better blance on fuel and performance could be obtained without the need for a gas conversion.

[andrewslr]

I had a VX Berlina LS1 fleet car from a previous employer. In those days fuel wasn't an issue and I averaged 15l/100km week in/week out with "spirited" driving most days. Highway/city mix. A Melbourne to Albury trip when the car was new actually deliverd average consumption of 8.7l/100km.

When I bought the R8, which mostly did peak hour suburban runs, I averaged 13-14l/100kms with 3.9 gears. That was with "sensible" driving.

Converting to LPG is a choice based on personal experience, but as a wise man once said "you don't buy a V8 if you're worried about fuel consumption!".

If the noose around my neck was looser, I'd be back into one tomorrow

[VT_5l]

why buy a sports car then convert it gas........you wouldnt buy a corvette then convert it to gas.....if fuel is an issue, you should have considered the purchase a bit more...

not trying to be rude, but im only 20
and work only part time.

Yes fuel is expensive, but you have to support your habbit and decision. I knew about fuel prices when i purchased the car and if it was an issue i would have purchased a Hyundai.
And the funny thing is, i did as a daily driver.

[da_ilks]

If gas injection kits offer the same power, at a significantly reduced running cost, I don't see why everyone is so against them?

Obviously, you have to take into account how km's you do etc to see if it's beneficial. Me? It'd take me about a year before the grant came in, so now I'm looking at 6 months. Seems worth it to me :)

[wablacksv8]

The government is already looking at added excise to LPG. Like it was said before as demand increases they will look at ways to make more revenue from LPG especially as people convert and petrol revenue declines.

V8s deserves better. Nothing like the smell of raw petrol fumes as you give her a gut full. Smell of gas, think taxi!

[da_ilks]

I love these consipiracy theories about how the governemnt is going to start adding taxes to gas.

The plans for an excise of gas was passed a couple of years ago now - doesn't everyone remember the taxi operators kicking up a stink saying it would put them out of business because costs would to be high?

The excise starts in 2011 and goes up 2.5cents each year, for a maximum cap of 12.5cents. Bit better then the 38.5 cents on petrol.

The government doesn't control the price of petrol or oil or gas - the oil companies do. The government only adds on their taxes.

[bodella]

Beware,
Just filled up on the way to work this morning, had done 590km and put in 62lts. So i think that equels roughly 10.5lts/100 average. I don't drive that hard at all but like i said 80% of my driving is at 100km/h in 6th gear. Maybe the Autos dont get as good fuel consumption out on the highway. My sits on roughly 1400rpm at 100km/h. I have seen the Lts/100 on the computer at 7.9lts/100 at times but normally it is on about 8.5lts/100 on the higway. But like we have all discussed in earlier threads the computer isn't really that accurate! And to be honest i don't mind paying a lot extra to run a V8 but i was surprised just how economical my new ute actually is thats all!!!

I agree if petrol is a major concern then don't buy a v8.

[saaz]

My previous car was a 5 litre VQ on gas. Even though it was a more basic conversion it still went well and was cheaper to run than a smaller car. I think I would prefer a V8 on gas than a corolla!

I have a WL 5.7 at the moment, but as it is on lease fuel is not a drama. It is pretty good on the fuel, so once you take into account no GST on the fuel, fuel card discount and better economy than the old car on gas, no need to convert it as the running cost are the same if not better. When I have to pay real money in 5 years, I will think about it.

[HRT.2FAST]

Parnell lpg systems in Thomastown ? i think can convert it with a lpg sequential vapour injection system ......around $4k

The problem is the car makes to much power so it will switch over to petrol over 140rwkws on a decending pressure regulator.
They are waiting for bigger injectors i believe.

I was considering it but ended up selling the car

Thanks Tim

Is anyone on the forum running LPG on a LS motor?

[Swordie]

If it was me I wouldn't rush into LPG especially if the car's motor is not designed to run on petrol. There is hardly any evidence how good an LS1 runs. I would try finding someone willing to put a warranty on the motor ECT. Gas run hotter and drier, typically LPG motors are strengthened. If the motor gets screwed it could be 5-7K worth the work.

[V8R]

search the forums for these questions, we've been debating it and posting facts (and debunking fiction) for the last cpl of weeks

[Thunder411]

Hey guys, Ive just recently purchased my Thunder SS a week ago and I must say the fuel economy is the best I have ever seen for a V8.It gets me 15.4L per 100km driving around town. 3 days ago I took it out on the highway and got 9.51L per 100km and the next day I took it out to the highway again and got 7.81L per 100km travelling at 110km in 6th gear. The 6th gear is a real help.
