Re: [John Muir Trail] fuel use
- Follow-up on this thread from several weeks ago - on the question of how
many fuel canisters to take.
Just back from 12-day trip. I used one (previously used) canister while
near Muir Trail Ranch (my start and end point) and another (brand new
small-size isobutane mix) for 18 meals on trail.
For those 18 meals. I consumed 82.2 grams of a 110 gram canister of Snow
Peak GigaPower isobutane mix in my JetBoil in cooking the 18 meals, or an
average of 4.56 grams of fuel per meal. The amount consumed was calculated
by weighing the canister on a very accurate postal scale before and after
Half the meals were 8 oz. of water, 2 oz. of butter plus 1.3 cup of 5-minute
breakfast cereal (Cream of Wheat or Instant Polenta premixed with almond
meal and sugar). Brought to simmer once, allowed to steep in the JetBoil
about 5-7 minutes then re-brought to a simmer.
The other half were roughly 12-14 oz. of water with various soup-stew
additives like Israeli couscous, lentils, split pea soup mix, meat, fat or
oil, dried or freeze-dried vegetables. Simmered twice similar to the above.
Water to start was typically quite cold and I was using the stove mostly
above 10,000 feet since I prefer to camp fairly high. I tend to use the
stove at about half or less of maximum power on the assumption that this
makes the fuel lasts longer.
On one occasion the stove blew out and it leaked gar unproductively for
probably 5 minutes before Irealized it.
On another occasion, I simmered some extra water in order to steep some sun
On one occasion (soba noodles for pesto) I left 16 oz. water on simmer for
about 5 minutes.
No use of fuel for heating water to wash, etc.
At that rate, I should be able to get 12 days -- 24 meals - out of my
JetBoil and the small canister.
People who don't need a steep and re-simmer process (e.g., those who just
pour hot water into a freeze-dried bag) could probably get buy on somewhat
If you own something like a MSR pocket Rocket, you will need more fuel than
this. The JetBoil is the most efficient stove analyzed by REI in terms of
heating capacity per 100 grams of fuel.
