[pct-l] Isobutane Canister performance

[Mary Kwart]

 Hi:

I had the same results using the same size and type isobutane canister
on 5 weeks on the Colorado Trail at an average elevation of 12,000
feet and at colder temps.

I hope the outside temperature stays the same for all your hikes. Same
with the water temperature before being put on the stove.  Make sure
to stay at the same elevation for every meal.  Otherwise you will
find all your calculations are unreliable in other conditions.  Just
a few considerations.

 Hi, all:

 I just finished hiking the Oregon section of the PCT and finally got
 to definitively figure out how much fuel I use. I packed an MSR
 isobutane cartridge that had an 8 oz net weight. I boiled 1 3/4 cup
of
 water daily and put the boiling water in a freezer ziplock with the
 food in a cozy to cook. I used a snow peak canister stove attachment
 and a titanium pot. It took 6.1 grams of fuel to boil 1 3/4 cup
water.
 I still had about a quarter of the fuel canister left after I reached
 the Washington border. Now I know how to gage what's left in all my
 partially used canisters at home. I can get about 37 days of 1 boil a
 day from a larger MSR canister.
