Sounds like a decent thing to do Jack. Nice present...at least it's something useful.
I know several folks over on the street-rodding and other old car forums from down there that also run propane conversions.
I've never asked about the economics down there but like Alpo I'm curious too if the difference pans out.
I know it still does up here in the upper midwest but you seldom see the newer OBD2 vehicles with propane conversions, but there are still a few of the older carbed vehicles that are converted...mostly farm trucks/pickups.
At one point in time a couple years back the break-even difference was $3.25. If gas was under 3.25/gal then it'll pan out cheaper than propane. But both prices fluctuate around so much that you really need to calculate current figures.
BTW Alpo, propane weighs in at 6.76lb per gallon so in a standard 20lb portable tank you've got 2.96 gallons in a #20.
The last time I filled my 20s about a month ago, it was $16 plus change to fill a 20lb tank that was bone-dry. My cost was about 0.80 per lb or as billed on the receipt $5.48/gal. This is for farm fuel...no road tax included.
But if it's for a on-road vehicle you do need to pay road tax just like you do with gas, diesel, etc. I'm not sure what the figure is at the moment.
There is less energy in propane than gas but unless you're driving a grossly-underpowered vehicle you most likely won't notice the difference.
My uncle ran propane conversion in his farm pickups (4x4, 1/2 and 3/4 tonners) for several years but I don't remember the exact mileage he was getting with them anymore.
I do remember helping do oil changes on em and the oil would come out nearly clean as when it went in. Propane is a much cleaner burning fuel so there are fewer combustion by-products to crud up the engine.

I just noticed this part of your post. At least you're doing the conversion right!
Some guys would just stick propane on the stock system and complain about it not working right and no power.
Kinda like running E85 in an engine tuned for gasoline...it doesn't work properly without mods. But I probably shouldn't have dragged that subject up.
what's the price of gas/fuel down in Australia for a gallon/liter?
Here in South Dakota (middle of country) we run about $3.19 a gallon.

petrol ( gasoline ) is $1.68 a litre ( unleaded) more for the higher octane ones ($ 6:30 a gallon)
LPG is 57 cents a litre and why the switch over ($2.10 a gallon)
Jack I think your missing a part for the conversion. My dad use to do these conversions. He's been gone many years now. But I remembered he converted all types of engines back then. Riding mowers farm tractors a model T forklifts trucks of all sizes and cars. If my memory serves me there is a regulator/pump( for the lack of knowing the real name) that goes on the fuel line between the tank and the carburation system. The ones he converted started on Gasoline, then you switched to propane after it started. Gasoline starts better in colder tempatures.
I'm amazed at the price difference there for the 2 different fuels

( both branded products here ) help out if it has been freezing or such
the higher up and broader throat allowing more air in allows for easier combustion too
the 1 thing we do use here is a oil dripper ( a oil feed line that only allows a very small ammount of oil in) propane or LPG gas is a dry fuel and this has to be factored for ,
by allowing a drop of oil in every 160 rotations of the motor you introduce enough lubrication into the system to counter for the dry fuel like propane ..
but thats a standardised part here ( and got off a taxi) i just gotta re bend the feed tube for this block , drill and tap the hole and insert the feed head and attach the line at the back , 1 litre of oil will lube enough for 4-6 tanks of gas ( 110 litres of propane per tank ) but i gotta mount it all up before bending anything soo .. that'll get done on the day
only hassle with a Christmas present like this is it's not really a surprise
ya gotta get the folks ya doing it for onside ,
the surprise part comes when they bring their car over , and see 15 blokes there and their ladies helping out , a BBQ and its all set to rock and roll
thats when the surprise part comes in
the gent himself is just a average bloke , not part of my church or like that , not a veteran , just a neighbour , he is in the Rural Fire Service http://www.rfs.nsw.gov.au/, if theres a alert he's there, if someone needs a hand , they can call him , he'll rock up ... ,
works hard raised a good bunch of kids , poorly Mrs sadly, suffers from asthma badly
a decent guy , so a few folks have had a chat and put this together , its a bit last minute but thats ok too ..
theres about 35 folks in on this so far
but this is how things where done when i was a lad , and i think there should be more of it , somethings and ways, well they where way better the old way eh ..
That is a GREAT Christmas present. This is what Christmas spirit is about.
Years ago I had an old TO-30 Ferguson tractor that ran on propane. Oil was as clean when changed as when originally put in. Power was good but a real bear to start. I would have to loosen distributor and retard timing, crank tractor and then advance timing after if started. One extremely cold morning the regulator froze and when I shut motor down it kept sending propane into engine thru open valves and out tailpipe. Had to pour hot water over regulator to stop it.

Jack I don't care what everyone else says about you. You are one decent human bean in my book. You are the type a person I could sit down with and have a shot of mash with and not worry if you would try to do me wrong.
