Bottled LPG v. Auto LPG

None..... you can buy a old fitting from the wreckers and put it on the side of ute that go,s to your bottle on the back of the ute. HEAPS cheaper but dont let them see you. Cheers tb

Nick, 45Kg bottles LPG are Propane, Auto gas is a combination of Propane & Butane.
Cheers Dave....

G'day Nick, I cant comment as to whether not there is any difference between Auto LPG & LPG used for domestic purposes.
We use 45 Kg Cylinders for home heating & the delivered price is $85 per cylinder here in Newcastle. We also pay rental on the cylinders, the cook is not home at the moment so can't ask her how much it is but I think it is considerably less than $55.

Auto LPG is a bit more refined then bottle LPG.

With LPG for BBQ's and the likes you are paying a handling and storage fee.

What you got charged seems very steep, we pay about $70.00 per 45Kg delivered to metro Adelaide plus a $55.00 yearly fee.

Price of LPG at my local (southside Brisbane) is 61.9

A few years ago when i owned acreage, we had gas bottles for heating only. The gas delivery service was so poor, i decided to use 9kg bottles, it was actually much cheaper but a 9kg bottle only lasts a few days so it was a pain . Price wise, i could fill a 9kg for $10 but i still can fill in the south west suburbs of Sydney, where i work for $16 now so if you times by 5,, it gives you your 45 kg, its still only $80 in todays money.. A 30% saving... food for thought.. Michael

Bottled LPG, BBQ LPG and car LPG is the same stuff. I would think that car one (cheapest) actually cleanest. They simply rip you off because they can. Get car gas tank from wrecker, put it on ute and refill it. You will save fortune, though I think it is illegal.

Interesting to read some of the shoot from the hip" replies regarding the differences between auto & bbq gas. Davo is correct in that auto gas is a propane/butane blend whereas "bbq gas" is propane.

There is a VERY good reason why the blend of the two gasses is illegal to sell as BBQ gas - they have different specific gravities and will seperate in the gas bottle unless regularly shaken.

Should the two gasses remain seperate, at the point where the liquid propane is expended (butane is heavier than propane) during combustion (say in the situation of an stove or bbq burner) there is a risk that the flame may extinguish during the change to the utilisation of butane for the combustion process.

Blind Freddy would realise the implications of this situation, particularly in the case of the indoor stove.

Lets get the facts right mates..
Car gas is largely unrefined gas straight out of the ground. Thats why it is a lot cheaper. It is a mix of mainly propane and butane.
LPG for home use is pure refined propane. Butane is used in cigarette lighters. In some remote locations car gas is the same as home LPG simply because it is uneconomic to take 2 truckloads of different gases to remote areas. Car gas can be used in BBQs (outdoor) but I would not be using in the home because of the unknown and variable mix of gases and therefore unknown emissions. In fact, when I lived in Wantirna (Melbourne) the local servo used to fill its BBQ gas refiller bottle straight from the car gas dispenser.

BTW the price of a 45kg bottle of gas in SW Vic is $90. Annual rental $28. Maybe you should hop across the border to get your gas , Nick !!

Top point Nw,
And jury seems out.
So good onya for raising a point that many of us think about, but just shrug the flamin shoulders and pay the price, eh.

We burn about 40kg/annum,(kitchen stove only), so if density separation were to happen, it would surely happen here.
The 2kg bottles in the back of the ute are pretty well shaken AND (dis) stirred prior to each use, but they cost a mint to fill.
Add to that the 10 year test date, and that's why I've gone (largely) to charcoal.
Best I stop, but I'm pleased you made the point.Very interesting.

"What is LPG fuel?
Liquefied petroleum gas (LP gas or LPG) is a hydrocarbon fuel comprising propane, butane or propylene, either separately or as a mixture of any of them. Automotive LPG is not the same as the LPG used in BBQ bottles.

The quality of LPG for automotive use is controlled to ensure consistent vehicle performance under all driving conditions. The gas is liquefied under moderate pressure; when allowed to revert to vapour it expands 270 times its liquid volume.

This enables LPG to be stored as a compact liquid but burnt as a dry gaseous vapour. LPG is non-toxic, non-corrosive, free of lead and heavier than air. It is produced by refinery fractionation of oil or is stripped from naturally occurring Natural Gas.

Is LP Gas used to fuel motor vehicles?
Yes, LP Gas is used to fuel motor vehicles, however a combination of propane and butane (also known as blend) is used. It's different to heating gas and BBQ gas, which is straight propane.

Can I use propane in my car?
Yes, you can use propane in your car, however most places don't sell straight propane because it's slightly more expensive than blend (propane/butane mix). It's thought that straight propane is better for your car (in both environmental and in performance terms) and our Somerton branch on Hume Highway happens to sell straight Propane so next time you're going past - pull in, fill up and you be the judge.

What is the mix in blend?
The mix in blend is a combination of propane and butane normally around 50/50. Blend is commonly used for forklifts and motor vehicles. The exact percentage varies all the time and is available on request. Phone our Dandenong Branch on (30) 9706 6262 to find out more.

What is LPG Autogas?
LPG stands for Liquefied Petroleum Gas and is the generic name used for mixtures of hydrocarbons (mainly propane and butane). When these mixtures are lightly compressed (approx.800 kPa or 120 psi) they change from a gaseous state to a liquid.
LPG is colourless, odourless and heavier than air. A chemical is added to give it a smell like rotten cabbage, so that even a very small leak can be easily detected. LPG burns readily in air and has an energy content similar to petrol, which makes it an excellent fuel for heating, cooking and for automotive use.

Automotive use LPG is quite often called Autogas (or LPG Autogas) and is specifically designed for use in a vehicle. LPG Autogas can contain both propane and butane with the specification (or blend) governed by the requirements of the National Fuel Quality Standards Act 2000 and the Autogas Determination 2003.

Is LPG Autogas different to LPG used in a BBQ?
YES. There are two different grades or blends of LPG and they are not interchangeable. LPG Autogas is for automotive use only and will be a mixture of propane and butane. The other blend is propane, which can only be used for decanting into cylinders for barbecues, camping, caravanning and household use.

Guys,guys,guys,

Now I work in the gas industry and can tell you that it all comes from the same tank !

Full stop

Swampy

Just had Gas inspection on the m/home i asked the inspector what the difference was his blunt answer was the auto gas is the dirty gas.Hope this helps to explain.
Bob.

To All the gas may be different but I have been using auto lpg in BBQ for about 3 years now with no problems. you just have to be able to fill the bottles
regards
Ozshooter

used auto gas for 20 yrs at home and in caravan
never had a problem with anything
have 2 gas hot water, gas cooking, gas central heating, gas bbq
in caravan gas hot water, gas fridge, gas cooking, gas bbq
fill up the Ford on the way home from work then fill 2 x 9kg and then refill the Ford on way to work in the morning
9kg bottle cost $11/$12
do keep my 9kg bottles in date by changeover or buy new bottle when on special for $25/$30

next door mate has deloused fork lift bottle he fills to fill his house and caravan gas bottles

swampy & serg are absolutely correct ,no discernible difference each may vary in the proportion of propane butane but thats it. been filling lpg from servos for last 12 years also decant from 45 kg to 9kg and 2.5 kg the only thing is be careful not only illegal but hazardous at best keep short the tube from the filler to bottle it is pumped in at a much higher preassure than static storage use,flared compression with liquid teflon check with snoop and when you unhook even with a non return the residual gas in the lines is liquid make sure no static and claer windy spot, pure butane or propane are hellishly expensive.dont believe any company/corporation with a vested interest.
