How much Fuel should I bring on a 5 day trip. I plan on cooking for breakfast and dinner. I have two 220g fuel canisters and I am only cooking for myself. Is this enough?

Thanks!

Water tempature plays a big role in boil time. Ice cold water will take much more fuel than warmer water. By warming water in the sun or in your pack you can save fuel.

This question has a few variables mainly due to elevation, temperature, & wind conditions. For instance @ higher elevations, above 11,000 ft, I use 9 to 13 grams of fuel per usage for 16 oz. of water. Eight ounces of fuel is equal to 226 grams. So for me, I get between 18 & 26 uses from one 8 oz./220 gram canister. If you use your stove four times a day, an 8 oz. canister will last approximately 5 to 7 days max. I hope this helps.

Just want to second what Phil said. A 220 gram canister should be plenty. I have done several longer trips, 6 & 7 days with the same size canister and have never come close to running out. If there are others in your party carrying the same size canister, you probably don't even need a backup as their extra fuel would probably get you through the trip, but if you're solo definitely bring a backup just in case.

If it's warm enough out (40F-ish+), one 220g canister will be plenty for 5 solo days. Even if you double the 3.5 minute boiling time per liter in the specs, you're still only talking about 70 minutes of burn time on a canister that should give you at least 90 minutes. Not cooking on high is also a much more efficient way to use fuel. If it makes you feel more secure, go ahead and bring the second canister, but don't be surprised when it comes back completely full.
