Planning a 6 day 5 night 2 person trip, first time using a whisperlite stove. How much fuel should we bring?

Maybe a search on the subject... Canister or white gas. Kind of meals. Eat fish. Coffee... You a boil your water or a filter person. Cook at all over the fire? Lots of variables... If canisters, size of canisters. Also how hot your dish water and how much you use...
Personally I play around with it all winter which you probably don't have... So I'd at least try a couple meals at home to get a handle on how much you might use. I'm guessing 16 oz would be more then enough but 8 would not be enough... But if your cooking fish over the stove you might use a little more depending how many meals.

Welcome...

Fuel usage is pretty consistent between all stoves I have used. All the MSR variants, Primus burners, Coleman, and oriental versions, gas and liquid fueled, I just take the same amounts. 8 ounce canisters or a 10 ounce fill for a liquid fuel stove cook very close to the same amount of meals, have seen no edge for any particular stove. For your Whisperlite a 20 ounce bottle filled with 18 ounces should be plenty, or 2 11 ounce bottles holding 18-20 ounces of fuel, if your still worried about consumption a 30 bottle is available.
Personally I can cook with 10 ounces solo for 10 days, 2 hot meals a day and coffee, but that includes some campfire cooking.

Percolator coffee and oatmeal for breakfast, cold lunch, and dehydrated food for dinner? 33oz if you are efficient, 44 oz if you can't cook over a fire with your gear. Cooking over the fire is always my backup plan.

Always carry more than you need until you get your process dialed. 44oz is probably much more than enough.

MSR's web site has specs for fuel burn per liter of water. I typically use those to decide how much fuel to bring, have found them relatively accurate. Whisperlite Specs

I take a one-liter (35 ounce) bottle of white gas per 6 to 8 day solo. If i go with the family, I pack the 1 1/2 liter bottle and a back-up 1 liter. It's overkill but if it's too wet for a fire or a fire-ban is on, then the extra fuel comes in handy.

It's hard for anyone else to give you a definitive answer, especially based on the limited information in your post. I use a JetBoil canister stove and for the trip you describe, I'd need about the amount in a small canister with a net fuel weight of slightly less than 4 oz. I'd probably take the next bigger one for some margin of error since sometimes that would be a tad more than I'd use, but might also be a tad less than I need. That's probably not realistic for you though; you need to figure out your own needs based on your cooking style. The burn time linked from the manufacturer will give you a good starting point. Just take plenty the first trip and keep track of what you used.

I do almost exclusively tandem trips of 5 to 10 or 12 nights. Coffee and clean up at breakfast; no cook lunch; a variety of dinners from freeze dried to pizzas and cakes for dessert. Occasionally make coffee or hot chocolate at other times. I'd take three 20 ounce bottles for what 5 nights, but pretty sure I'd only be well into the second at end of trip. I've probably not kept up with the fact that I used to do cooked breakfasts and should cut back, though I don't know how change from Whisperlight to Dragonfly - which simmers at low flame well - affects fuel use. A cake (or bread or brownies or muffins) might take 30-40 minutes but at the very lowest level.

8 ounces of white gas a day should serve you well. Not that much to carry on a canoe trip. I have to get better at not taking extra for backpacking.

Only two things worth knowing on this subject.
1. The Whisperlite is the stove I bring only when I figure I'll need something to keep my mind occupied while fixing it during an extended stay in a tent because of weather.
2. Everything else on the subject of stoves is here: http://zenstoves.net

We took a whisperlite and used about half of a 20oz bottle. We did use fire for boiling at times and cooked over another stove a time or two. If we'd have just used that one stove and no fire, I still think we could have done it with one bottle. I took an extra in case since it was our first tandem trip. I'll take less next time

I own three Whisperlites and love them. I feel like I can use them pretty efficiently when I need to... no need to senselessly burn fuel when not using the stove.

For two people on a 6-day, 5-night trip, I'd carry a 33 oz (or equivalent) MSR fuel bottle. Depending on our menu and how we use them, I "might" carry two 44 oz (two 22 oz) MSR fuel bottles, but I can guarantee that we'd be carrying home a fair amount of gas.

Sure, gas weighs a little bit, but would you rather carry a few more ounces or risk running out?

5 ounces white gas per person per day with a Coleman Apex ll is plenty doing all the cooking plus water for dishes--no cook lunch unless cooking fish on a layover day.

How long before you leave?

Cook a couple of meals in your backyard and measure your actual fuel usage. A little practice with a new stove before a 6 day trip is probably a good idea anyway.

Good Luck

It's been quite some time since I've used my Whisperlite Int'l and mine is quite an old model where the reflector that goes under the burner had a hole in it so you could put it on the stove rather than putting the stove on the reflector as is currently the case. Long story short I was on a trip and had gotten lazy and wasn't putting the reflector on and it was just gulping the fuel (relatively speaking) then I put the reflector back on and it went back to its miserly self.
My point is, that if you use all the reflectors and windscreens you'll get better mileage out of the stove.

The variability in answers to some questions never ceases to amaze me. It seems that you should take somewhere between 16 ounces and 44 ounces; both are probably more than you'll use.

A lot depends on what and how much you cook, and as redoleary pointed out there are ways to use it more efficiently.

So, just curious if you have decided how much to take Walleye1?
