TIP: The online Bushwalk Inventory System can help bushwalkers with a variety of bushwalk planning tasks, including: Manage which items they take bushwalking so that they do not forget anything they might need, plan meals for their walks, and automatically compile food/fuel shopping lists (lists of consumables) required to make and cook the meals for each walk. It is particularly useful for planning for groups who share food or other items, but is also useful for individual walkers.

Gas usage

Mon 11 Feb, 2013 12:42 pm

Hi everyone, as the title says, how much gas do you use on average a day in grams if possible, allowing for 4 cups of tea(400ml), and dinner boil up (500ml), reason is the last trip my friends stove used twice as much as mine and we cooked the same and one stove is jet boil and mine is an old MSR brand stove.

Cheers

I checked our consumption after (5 mornings/evenings) on the OT and found we used 30g of gas per night. The daily usage was 3 x 500ml boils for soup/tea/hot chocolate and 2 x 200 ml boils for couscous and and 3 x 600ml boils and a couple of minutes simmer for pasta. Stove was a Fire-Maple 118T (not inverted) in 900ml Ti pot with lid.

Often the reason for high gas consumption is running the stove a too high a heat for the pot diameter. You should not see any flame licking out from under the pot.

Yes you would expect a Jetboil to use about 50-70% the fuel of a 'normal' gas stove.

I allow ~30g per person per day using a normal (i.e. without heat exchanger) stove and pot.

my friends stove used twice as much as mine and we cooked the same and one stove is jet boil and mine is an old MSR brand stove.

From that I understand that the JetBoil used twice as much as the MSR, not the other way around.
It can go either way depending on how one uses the burner, just like driving a car...
High heat setting, boil for longer than needed, boil more water than needed, boil in the wind, using colder water , are some of the reasons that can affect any stove.
pot size is not an issue with the JetBoil.

I agree that keeping control of the gas output is really important and I have found that that my FMC-XK6 heat exchanger pot did save gas and well worth investigating :)
