can i use canister fuel with this stove for months, leaving the liquid fuel for the freezing winter months without harming it?
No, but if i were you I would re-light and test the stove before would heading out into the backcountry
No and cannister stoves are notoriously bad in the cold. No pressure in low temperatures to keep the flame and heat output high enough. Gas doesn't freeze unless there is water in your fuel/fuel line. .
Yes, you can use canister gas in the summer and white gas in the winter.Using either for any amount of time won't affect your ability to switch to the other when needed.
