Commodores have two motor options. One for use with petrol and one that can use either. If you try gas on the normal motor then you're in deep s**t (that's if the installer is stupid enough to do it)

Anyone had LPG on a series landy with a holden donk? I'm considering putting mine on gas to make it a bit cheaper as a daily driver but I want to keep my dual fuel (petrol) tanks as well. We used to fit a "black box" to your dizzy to change the spark curve between gas and petrol when you switched between them - is this still done (or something like it) for carby/non computer engines?
Its been a very long time since I had anything to do with LPG - we used to fit IMPCO converters and mixers, everything else was a cheaper brand, that seemed to give the best performance - I'd be keen to hear of others experiences with this kind of application (series landy with holden).
cheers,

My ex-mil Landy mate (ex-RAEME mechanic), whom some of you will know, drives an ex-taxi Ford factory dedicated LPG car that was driven by his girlfriend as a taxi. It will get from Sydney to Melbourne on a tank of gas and is about to click over 1,000,000 Km without any engine failures apart from regular service. He also did the servicing of the car as a taxi.
You can't complain about reduced engine reliability on LPG with examples like that running around.
A holden motor is a holden motor.
I used to drive a Kingswood taxi around Melb in the 70's & the owner owned & serviced 42 cabs at his own garage. I asked him what modifications he did & his answer surprised me- he fitted a fan blade with more fins. :eek:
He was a cheapskate, but there were cabs in the fleet with over a million clicks.
As far as the latest with dual curve etc, I went down this track with the Chev motor ( carby) and the converters I spoke to said to run premium petrol & tune for gas & you won't notice the difference.
I just did a trip over Easter to the Big Desert in Vic & The Boarder Track , We had 5 cars a Rangie Classic manual stroked to 5Ltr on Lpg , a 93 Disco Auto 3.9 v8 on Lpg , a GQ Nissan 4.2 efi manual Lwb on Lpg , A 96 Tdi Auto Disco towing a trailer , and my Td5 110 Defender .
The result being all the lpg powered cars used twice as much fuel + more litres as the diesel cars .
After doing the big desert we went too Pinnaroo in SA for fuel , My Td5 took $35 worth of diesel and the Tdi disco with the trailer took $45 worth of diesel all the Lpg powered cars took over $50 + of Lpg which also was a lot more litres than the diesels :p
So in the bush there is no saving in having Lpg :p
In saying that my Td5 Defender returned on the Hwy fully laden and with a roofrack sitting on 110 kmh 10 litres per 100 ks:D
All the Lpg cars had dramas of some sort with their Lpg setups .
Fair enough, but at my stage in life I can't justify spending over $20K on a vehicle. V8 Disco's are astonishingly... for the time being that's what we'll run.
Let's take LPG out of the it for a second, the vehicles are petrol powered engines, and the costs would be a lot dearer in petrol, and consumption of petrol powered cars are always going to be more than a diesel.
having LPG will save on refueling expenses when it replaces petrol being used as a fuel.
Diesels will always be a more economical choice for long distance bush travel.
The range of a diesel is longer, I can vouch for that when I travelled from Melbourne to Mildura and then onto the Flinders ranges in SA, then down the S.A coast. I can't recall how many constant stops I had to make to fill up LPG due the the limited range. LPG limits my of the beaten track ( so to speak) adventures due to supply and range. I don't particularly want to carry numerous jerry cans of fuel either just to ensure I have the extra range when the LPG runs out.
My next vehicle has to be a diesel.
