My 20 oz bottle seems to be just right for the 2-4 day backpacking trips I take with between 2-4 people, cooking 2x daily. Last trip to Ramona Falls with 4 people including dumping some fuel on wet wood to try to start a fire left us with about 4-8 oz of fuel left.

If you're using MSR superfuel, be careful. Jose almost singed his eyebrows from lighting wet wood doused with white gas. It was quite the fireball.

I have 3 bottles, one 11 oz and two 20 oz. I am using the MSR WhisperLite stove, and the 11 oz will last about 3 days if your cooking for two people. And the 20 oz will go about a week for two people. The cap has a rubber O-ring that seals the bottle from leaking. So no need to over tighten the cap, just give it a good snugging and your good to go.

These bottles will last until you loose them- there's no way of breaking them. Also cheaper than other brands. The cap has a big loop for clipping it to your backpack and also two small holes inside to handle the fuel without spilling. In Aconcagua the porters use mules to get your stuff to BC, this is your best option, no leaks at all. Hope this helps.

I have all three sizes and I like the 11oz one if im just going to be making lunch on a hike or maybe lunch and dinner on an overnight.
If im going to be doing much more than that ill go for the 20oz
I cant say as I really use the 30oz much...

I have many MSR fuel bottles but the 11oz. (small) is often times clutch in getting every last drop of fuel burned when using it with and MSR stove. The smaller size allows the fuel to sit higher above the fuel pump. For example think of putting 8oz of water in a 16oz glass (it is half full) now put 8oz of water in a 10oz. cup and it is now 80% full. This is really help full to burn every last drop. What I do for backpacking is carry the middle size (20oz) and the small (11oz) alongside. There are several big advantages,

#1 If you have one fuel bottle and you were to spill it or puncture it you are totally out of fuel.
#2 You and your partner can each carry a little in case you were to be separated and need a little fire starter.
#3 The small can make it easier to burn every last drop
#4 If you go for a 3 night hike the 20oz is a perfect size, so just consider the small 11oz size your back up fuel for emergency or weather related use.

I have used my MSR XGK EX in 17 different countries and at very high altitudes with white gas, diesel, kerosene, unleaded, and fuel with things floating in it (nothing like South American desperation). I swear by this stove it is one of my most reliable and trusted pieces of gear.

These are awesome. You should get them..but know you won't need the biggest bottles unless you do a ton of cooking.

These are great. Very durable, a number of sizes, and lightweight. I have the small size for short weekend trips and the large for week long trips. I use about 2/3 of a bottle of the small 11oz on a weekend trip making 5-6 meals. I have had serious problems with overtightening the cap. I had a scare when I couldn't get the cap off and I was 25+ miles from the car. Don't over tighten and you'll be fine.

great container. I had a numbskull moment and cross threaded it and didn't screw it down all the way (totally my fault) and it didn't ruin the cap or bottle but it did leak in my food bag. Learn from my lesson and make sure it turns at least 5 times and not just 2. Test for seal before putting back in bag. The bottle is great * some times the user isn't.

probably too big for the amount of trail cooking that i do, but gets the job done. the new safetylid is a little awkward in my opinion, but this thing definitely takes a beating and works well.

MSR makes a great product. This is no different. Although it is something as simple as an aluminum bottle, it is important that you get something that is made well. This bottle doesn't leak, is VERY sturdy, and you can put cool stickers all over it! I wouldn't recommend any other fuel bottle.

uuhhh...the 11 oz bottle is so cute!!! cant really say anything bad about any of these 3 bottles..they are all awesome and well made, durable and deffinatly the fuel bottle I want to take out with me.

What can you say, it just works and its light. I have 2 20oz and 2 10oz. I find that I use the smaller ones more with my WhisperLite just because I'm not cooking for an army. But always good to have multiple choices!

The 30 oz fuel bottle lasted me the entire weekend boiling water for 13 people on an MSR Dragonfly in 10 degree weather and still had some left in the bottom.

Two 11ox bottles for three people for three days, two nights with plenty left over.

These bottles are sturdy and don't leak(o-ring in the cap).

I like their new-to-me child-proof bottle lid.

These bottles are sturdy and well-made. They take a beating, and still do not leak. Among other uses, the loop in the lid allows you to open lids that have been over-tightened (by putting a branch through the loop to get more torque). The little bottle is good for shorter trips, while the larger ones can be used for larger (or more cooking-intensive) trips.

it holds fuel and stands up to some abuse. It works like it should.

no complaints, durable, and does its job.

These bottles work great for carrying any fuel you need and Ive never had a complaint about leaks

Worked much better than I though they would. No leaks, easy to handle and a great product.

To whom this may concern:

I just purchased a 2009 Harley Davidson, Sportster Custom XL. During the delivery process my sale rep informed me that there is only a low fuel indicator light. This being a new Harley and I was not sure of what the MPG's are for the city/highway I need some peace of mind knowing I wouldn't run out of gas. I seached the web to find BackCountry site and also realized this site was cheaper than the HD dealer and other sites, to include, having the larger 33 oz. MSR Fuel Bottles with free shipping. Now I carry three of them in my saddle bags with no worries about running out of gas!!!!!

Thanks,

Satisfied Customer

Short of runing it over with a tank, these are almost impervious to damage. I have the big one since we like to cook and use it all the time. Paired with whisperlite international stove is a great combo. Been burning Coleman fuel without issue.

Used this to carry Coleman fuel for an old Optimus 8R. Even in the trunk of the car for 8 hours at work, there was no leaks. Couldn't say the same for the stove. Well designed and seems real strong.

Concerned about the safety tops and the ease of their removal based on other reviews, but they seem to work just fine. Got the medium size as a balance between capacity and ease of pressurization with the fuel pump. No problems!

You should never have any problems with this bottle and it should last you as long as you need it to. These things are basically indestructible under normal circumstances and I have never had any leaks or problems. Great product at a great price!!

I use these 30 to 33 oz. MSR fuel containers to safely store and transport 2-stroke gas mix on my Golden Eagle converted Mongoose bicycle. These containers provide me with additional fuel capacity and range.. Going 30 plus MPH on flat ground without pedeling is a blast.

Got all three of them: the 11 oz, the 22 oz and the 33 oz. The 33 oz (or one liter) is good for motorcycle trips, as you can fill it from the tank if you have a couple of feet of vinyl tubing, or pour it back into the gas tank if you run out of gas on the road--that might get you about 10-15 miles closer to the next gas station. I got the 11 oz bottle for backpacking, but seriously, nowadays I think my Whisperlite International stove is too heavy for 3-season weekend, or even week-long, backpacking trips. (It's still a good winter stove, though.) Got the 22 oz bottle just to complete the set... They're all good, rugged fuel bottles, and the Whisperlite stove is good and rugged, too. Come to think of it, everything MSR makes is good, rugged and reliable.

These bottles are fantastic! Strong and can take a beating. They works well and I have used them for carrying white gas, chainsaw bar oil, and gasoline.

With the variety of sizes you can pick one that is right for your trip. This allows you to cut down on weight and space as necessary. If you get the small ones you can also split them up to divide the load. Extremely durable and are leak proof. You can through them in your bag with your clothes and not have to worry about fuel leaking all over them. They don't expand and contract due to temperature change like the containers you buy the fuel in either. All-in-all well worth the money even if you don't have an MSR stove to use with them. If you have a different stove that requires white gas you can transport in these. Just bring a small funnel to refill your stove.

I mean, really, you fill it with gas, put the pump in and let'er rip. It works. It doesn't leak. Rinses out easily enough if you want to try smuggling it on board a plane.

I've been really happy with this fuel bottle, it does everything that a fuel bottle should do, and didn't break the bank. There was one occasion on a backcountry ski trip when this bottle was kicking around the bottom of my pack and I could smell a little bit of white gas. Lesson learned, keep it on the outside or be positive that it's upright and you're good to go!

it very good , i like it
