LPGas for cookingLPGas for cars = difference

this contradicts some others thoughts

I had problems when lpg condensed in the piping over night . Liquid is a good scourer which flushes dirt from the pipes into the jets. I now use cotton wool

Some else sometime back said it was eddy currents over the face of the jet...which i queried, but now believe this could also happen....

As you say donmestic LPG is propane, auto is a mix of propane and butane plus a few other goodies. Butane has a higher heat content, diferent density etc and requires smaller injectors generally. The oil is not the butane but is added as an extra to the auto gas. I use those small butane canisters a lot and they are excellent with the correct appliance due to the extra calorific value IMO.

I don't know about being illegal to tip a gas bottle upside down to release gas but it's certainly dangerous.

I think I would be more worried about the fact that I would be getting ripped off if my gas bottle was being filled with auto LPG , bowser price = 45/60 cents per lt , LPG into gas bottle = 4.5lt bottle $15/18.oo = major rippoff !!!!!!!!!

I have responded to other posts on this subject, and have ended up with abusive emails from people who recon I'm an idiot. Whether or not I'm an idiot doesn't diminish the fact that a mate of mine is a registered LPG installer and he recons it is the same gas. He has worked at a service station for many years, and the truck that fills the tank with LPG for cars also fills the tank for gas bottles. The driver uses the same hose, and does not switch between different compartments in the tanker.

So, yes, send me information stating legal clap trap if you like, refer me to websites of related topics and call me an idiot if you like, but I still believe they are the same.

As for lubrication. If LPG does contain substsances for lubrication, then why did I have to have special valves put in the head of my landcruiser to deal with the lack of lubrication when running on gas? Many, many people have had to do this modification to avoid burning valves when running on gas, particularly on older vehicles that were designed to run on super.

Why are people advised to also use flashlube valve saver or similar products. It's because LPG burns dry and hot and contains no lubrication.

Bring it on !!!

Guy you are very wrong.

nothing more or less your just "wrong".....

yes thats true.

its dust and ice particles from when you turn the jets off and the flame goes out.
the dust is attracted the the ice from the inside of the jet use a jet clean neddle to clean.

this is true.

the whole of this statement is totally false.... butane mixes eventy with propane .the chemical traces for saftey smell mix evenly as well.butane ase is an gase with no traces of an solid. its only an liquid because its stored under pressure.
As for jet becoming restricted see about dust particales and condisation.

>It is illegal to turn upside down the gas cylinder and release the gas in the air

what contry you in???? where did you make that up?

when you turn the bottle upside down the liquid converts back into a gas via loss of presure.thats allyou can have an pick up for an gas vessal any where you want, its normally where you can ACCESS IT.

>Use an expensive gas filter or change the gas cylinder. (Someone else will have
>the problem)

a media filter for butane is a very large and bulky filter. you would be better to have an water trap instead.....BTW where are you going to get an "FILTER" for domestic use???

>LPG gas for cooking should not be used in cars, as they do not contain any Butane >or lubricating gas for the piston heads.

this is not true again ......

and lpg does not have any "lubricating gases" in it at all.....

lets get this right first up

lpg is a mixture of propane and butane with trace aromatics to give it an smell thats all.

bar-a-que gaes is propane with trace aromatics to give it and smell.... thats all

in europe you can buy with propane and butane gaese serperate. and you need different jets to run you settings.

if you want to know why lpg gaes is not fir for human cooking try googleing lpg - medical and cancer at the same time.

hi everyone, just throw my 2 cents in, my brother inlaw delivers gas down south sydney way and tells me it all comes out of the same tank , and over in nz they fill your gas bottles at the servo out of the same pump that you fill your car with. i think everyone has there own idea about it but i am going with my inlaw as he delivers it to both servos and camping outlets an it all comes from one big tank. ok it was 3 cents worth. peter

Why are there different mixes of propane and butane in LPG (autogas)?
Autogas consists of propane or propane and butane. Residential LPG (used for domestic cooking and heating) consists of propane only.

Fluctuations in the relative levels of propane and butane in autogas is not an unusual phenomenon; it is evident in autogas mixes used in other parts of the world, such as Europe. In fact, in Europe the levels of butane and propane fluctuate more than in Australia.

Maintaining different mixes of propane and butane is important for the continuation of the autogas market. The fluctuation provides for the flexibility necessary for the distribution of autogas to metropolitan and regional centres.

[B]Certain regional and rural areas are provided with autogas that consists of only propane so that both the domestic and automotive needs can be met with the one tanker load.[/B]

Near as I can tell car LPG and BBQ LPG are legally required to be different.

I owned a server for some years and know this.

However I also know that the practice of filling the BBQ gas refilling bottle from the car LPG tanker is rampant within the industry.

The issues with BBQ's etc are generally so minor that virtually no-one ever notices, nor do they think to test the gas in the bottle...Would you?

The largest issue here from a consumer point of view is one of rampant profiteering as the car LPG costs the service station MUCH less than the gas he should be putting in the BBQ refill bottle. Other health concerns exist but I suspect that unless we used this stuff everyday the risk would be slight. As my mother does as she lives somewhat remotely and has bottled LPG for cooking/water heating etc. The saving grace for people like this is that the bottles are exchanged directly with a (hopefully) reputable gas supplier who uses the correct gas.

If anybody is interested, LPG installers will sell you the adapter to fill your bottles from your vehicle filling point. Cheers Mick

Guy or anyone interested,
Here is a link to a hose to use a 9kg cylinder as a jerry can or to decant lpg into a 9kg cylinder from the car... copy and paste
