Quality of LPG?

Now that I'm happily back on LPG I've had some discussions about the variable quality available.

Apparently, the higher % of Propane the better. Supposedly, some mix various amounts of Butane and other gases and the quality of the LPG suffers.

I filled up today at Supagas, Dandenong, and they claim 100% Propane and describe it as "Premium" LPG. At 60 cents/L when all the servos are charging 68 to 70 it seems great value.

Opinions????

Hi there Jim,

Would Supagas give you better economy?

I believe the higher the quality gas, marginally better efficiency.

Jim
I filled mine up at Supagas Adelaide, asked him what type of gas and he said currently Mobil as they gave him a good price.

I believe BP "Auto Gas" is of high quality. but it must be from a BP Reliance station and be branded "auto Gas" on the pump. You can also get a card there that gives 2 cents per litre discount at Reliance stations, that is how one knows if it is BP gas as other BPs will not give the discount..


The more Propane the better, I believe that most LPG in Australia has some Butane in it, that is the rubbish that goes in smoke lighters
It is hard to get any info. on what gas is what. If any one knows where to research would please advise.

Regards
Norm

Not sure what the go is with ''better'' lpg but there sure is a difference between the servos around here and all over the place where we've filled up!

find a good spot and keep to it!

My mechanic has done some background work on the quality of LPG and it turns out that BP haven't quite got the refining process sorted and there can be a degree of oil in the gas which gas systems don't like. This was confirmed by a gas installer and a client of mine that works for Kleenheat Gas. Kleenheat apparently have the process well advanced (they have been doing it for far longer than BP) and the oil has been eliminated.

Can't confirm either way but makes some sense.

Kleenheat, Supagas etc etc all by from Australian refineries or some offshore producers.
They buy at the best price on offer at the time with consideration to transport costs.

"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. "

Sorry should have added this bit from the above site.

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.

For this bloke to be telling you its 100% Propane means he is full of $hit as it won't comply with National Fuel Quality Standards for Automotive fuels.

Hi John, I have read and heard about this difference between Autogas and BBQ gas before. I have also worked at a place which had a bbq gas bottle adapter for the lpg filler. All the workers used it for their bbq's without any dramas. A member of our 4WD club also has told me his friend used to drive a truck which filled up storage tanks of lpg at servo's and then filled up the bbq gas with theexact same gas.
Is this all just a big smoke screen to get us to pay more for BBQ gas???

In NZ you can only call it propane if it is 90% or higher propane content. Below that it just has the generic LPG name. Every tanker has a delivery sheet that tells you what percentage propane the load is. LPG is a mixture and may have heaps of butane in it. Some colder areas of the country always get a high propane content delivery as people who use it for home heating/cooking have difficulty with ignition and keeping a good flame going on a very cold day. The same tanker fills the bulk auto tanks at the petrol station. I always ask what percentage propane I am getting when I fill my 45 kg bottles at the bulk depot. I can tell the propane content as soon as I see the flame height/colour in my gas log fire. When I had an lpg car it was very apparent when I had a high butane content fill as I had to change down a gear on a local steep hill.

Jim,
When getting my gas bottle filled at Supagas on the Hume hwy I asked about the difference. The guy said straight propane burns cooler, gives better economy and is overall better for your engine. He also said that it is best to fill up on it when your tank is very low so as to not get too much of a difference in the gas mix.
I have not used it as yet.
