I did not say it was important. Butane does not flow in cold conditions. This Iso brand has a mix of gas that makes tha makes it flow better in cold conditions. there was a post about this recently which I can`t find. I think that the post gave the proportion of gas mix. Regards G.T.

The gas is not a mixture - its 100% isobutanne.

The molectular structure is different and this lowers it freezing temperature.

I've 2 different brands sitting here , Gasmate + Primus , neither give a breakdown of contents % butane / propane. Gasmate is made in Korea with Australian distributer Sitro group , Primus gives no info on can about manufacturer only a reference to Australian distributer.

"Iso Butane" - more properly Methyl Propane has a boiling temperature of -11.7 degrees C
Butane has a boiling temperature of -0.5 degrees C
Hence Iso Butane is better ona cold morning - you can make the coffee!!
Big W is selling "Iso Butane"

Thanks Fred. Now I see what the `Iso` means. I originally thought it was blend of gas so as to make it flow better when cold. Obviously it is a different gas. I paid $4.76 for a 4 pack today from Big W. I thought that this was a reasonable price. Regards G.T.

Still handy to leave it in a warm area overnight, such as the bottom of your sleeping bag. Many times I have been unable to use the isobutane in the morning and had to use another source for coffee/breakfast.

Thread hijack..

I presume this gas is for those single burner type stoves with the cartridge slotted into one side..
There was talk a while back about these exploding occaisionally.. How has your experience been? Obviously yours hasn't exploded ;-) but have you had any drama with them? Heard of anyone with issues?

Reason I ask is I'm thinking one could be a handy addition to my kit so I don't have to set up the Coleman everytime..

I have had one of these single burner stoves and carry the pressure packs ( usually 4 in a pack) all the time in the vehicle and had no issues whatsoever......I made some side panels for the stove to protect the flame from the wind so that I don't waste gas boiling the kettle.....they are a great addition and so compact and quick to set up and easy to use and you can buy the cans from anywhere and had no trouble with any of the can contents (gas) at all.
Where I live and go camping the temperature seldom is below 5 degrees C and so I cannot speak for those who live in colder climes and who use these stoves or any gas appliance.

Yep! I have two stoves as shown in Redbakk`s photo plus a mantle lamp ( Companion) No problems with any one of these. From what I understand if you put a skillet or a large pot, pan or what ever, so that it overlaps the gas cartridge area , flames from the stove could be made to heat up the gas cartridge area with disaster type consequences. Care needs to be taken. Regards G.T.

They are briliant imo. You can buy better flowing (Bigger Burner) stoves than the $20 specials for around $30-40. Use mine all the time.

We had trouble with cold gas and wind.

We bought a dingo kettle and wish we had bought it years ago,, its great in windy conditions and we don't have cold gas problems.

No smart comments please. LOL
