How Long Does an 8 Ounce Fuel Can Last? Jetboil vs. Optimus Crux Lite
HTML-код
- Опубликовано: 6 сен 2024
- Today we test out 8 ounce Backpacking fuel canisters to see how long they last.
The fuel used for this test is the MSR Isopro, which contains a mixture of 80% isobutane and 20% propane. This is their 4 season mixture.
I used 2 different backpacking stoves to see if longevity was also affected by varying stove types.
For this experiment, I used the Jetboil stove system, and the Prius Crux Lite. Both were set to full power.
Hope this video is as informative for you, as it was for me.
Take care and enjoy the great outdoors!

Great test. Thanks so much. I never dreamed my jetboil was that efficient. By your calculations I can expect an hour to maybe an hour 15min from a small can. That’s easily a 5 day “dehydrated meal” hike. Good info to know.
This answered the exact question and even a few more I had not thought about. Great content. I’ll be looking for more here.
I wish efficiency was the testing benchmark of these stoves. Yeah boil time is great but if it can boil 2 cups in 10 seconds but uses an entire canister every time then it's useless. But if I can get water to a boil with 200 uses then I know I can pack 1 canister of fuel with no worries.
Floordford amount of burn time / time taken to boil - should be able to tell you what you need
As far as given time with canisters: this should tell you you’re good either way with 1-2 of them. Typical resupplies are going to be 7-10 days for areas so 1 should last you because boil times don’t take much longer than 5-7 minutes typically. The shortest of the canisters had an average of 48 uses and it’s faster and that’s more than what you’d need before a resupply. Especially when the jet boil is bulkier and heavier.
@@brianbrooking496 You're missing an important factor for some people though. It's not as black and white as you'd suggest.
True Mordecai some people are hell bent on over complicating the simple things.....
@@brianbrooking496 Yeah, I agree, such as weight.
For me you answered everything i needed to know, and that's a rounder about idear of burn time, cheers from New Zealand.
jason manukau 🍻!
Perfect timing for the video! I just got a Jetboil Sumo as an award at work. I'll have to learn all the tricks to using it. It will fit in perfectly with my solo kit. Keep it up!
Al Sims thanks!
It's really more about how many BTU/hr each stove produces that determines the burn time. The Jetboil doesn't burn fuel as fast because the burner produces less BTUs/hr. It relies on the heat exchanger on the pot to more efficiently transfer heat to the pot. The open stove on the other hand, doesn't transfer heat to the pot as well. It needs to make more heat (produce more BTUs to accommodate for it's inefficiency. The real test would be to measure heat transfer to the fluid in the pot. I believe you would find the Jetboil to be about 30% more efficient due to the integrated heat exchanger and pot insulation.
D. Volvoguy that’s exactly what I noticed on this experiment. The Jetboil stove draws out less gas from the canister to heat their container. Very efficient system
the 'trick' is the jetboil limits the max output of gas to maintain a more adequate fuel-air ratio. but if you adjust the Crux to 'blue flame' all the time they will last pretty much the same.
you could try to adjust the crux to the maximum flow with blue flame (optimum air-fuel ratio) and check if the contraption of jetboil really makes a difference.
i dare say it will make less than 10% difference: the main barrier for water heating is the transfer between metal and water. that is why a frying pan boils water faster than a taller pan with same volume and tea-kettles have a very wide bottom.
The test you mentioned is not needed as it has already been performed. Once the two stoves boiled water in the same amount of time only one variable remained. Technically there is a chance that either stove could have been turned down a bit and the maximum flame might have remained constant...I did see a lot of yellow/orange flame in the beginning with the Optimus. Anything beyond a blue flame with most gas stoves indicates an inefficient burn. But I doubt it would lessen the difference between the two stoves very much...maybe 20 minutes? Perhaps 30 minutes?
And this is exactly the reason why the frozen condensate was on the optimus and not on the jet boil as the pressurized gas was escaping the canister at a faster rate. www.quora.com/Why-is-there-frost-on-the-outside-of-my-propane-tank
I tested by measuring weight loss from the fuel cannister. I compared an Optimus with and without a heat exchange pot. 11-12g of fuel without the heat exchange pot and 7-8 grams with the heat exchange pot. That tallies with other comments here about a 30% difference. To me the message is carry a little heavier pot to reduce fuel weight. The burner is less an issue if you set the flame to an efficient heat.
Thanks for the test. The fact that the fuel can on the Optimus showed frost when the JetBoil didn't was an indicator that the Optimus consumes fuel at a faster rate. If they both take the same amount of time to boil then the test reveals the Jetboil to be more fuel efficient (which I believe it is). The JetBoil's heat fins transfer more of the heat to the cup.
Last much longer than I expected!
Interesting. I was cheering for the Crux. I've used the Optimus Crux for about 12 years now, and I'm a big fan. I may be less efficient, but it's a rock star at high altitudes. This was useful info though. I've never really kept track of the burn time.
I took a disposable aluminum grilling pan and cut it to make a reusable heat / windshield for my cheap little stove. It works great a lot like the jetboil without the expense or weight.
I always wondered how long that darn canister would last. I should have tested this years ago. Thanks for doing this comparison!
Just stumbled across this video , and going bush in a couple of weeks , so this test was very handy thank you.
Just purchased the Crux. Haven't tried it yet. Now I know it's capability. Thanks.
I am thinking about getting one of those
Cool video,nice to see how long those little tanks last.I usually just prefer a campfire myself or sometimes I'll use a single burner propane stove although is it a bit bulky with a 1lb tank and the stove itself.
Since the one canister froze the butane wasn't boiling off. Propane boils at -43F, IsoButane +10F and Butane +32F.
So the Propane boiled off and was used. Don't know if your blended canister had IsoButane (some do) but
I would venture a guess that the Butane in the canister didn't boil off, hence wasn't used, or at least not in its entirety.
It would be fun if you warmed up the canister to see if you could get more use out of the remaining Butane. At any rate, great
test. I would never guessed that it would last 2-1/2 to 3 hrs and I use these quite often on my little adventures.
Thanks for posting, I often wondered about this.
Preparing for a minimalist car camping adventure and this was super helpful! Thanks man!!
nice vid! I use my msr stove for lunch on construction sites. Ive found that those small canisters will last me a whole month.
chris Gordon thanks! Yeah I really like how long most of these stoves last (msr is an awesome brand). 👍
I just got a jetboil and your video perfectly demonstrated that msr fuel cannisters can be used with it since i wasnt able to find any jetfuel brand fuel. Thank you so much.
Thanks for taking the time to do the video and answer questions that we all have, I’m using the Optimus for the CT bike packing trip in August, it burns better at high altitudes.
Thank you edward. Always remember guys. Every trek is a cleanup trek. Preserve mother nature. 😊
Truth^
Thank you for taking the time to do this.
ARhere you bet. Thanks for watching!
Much appreciated. I have owned a Crux for 4 years now, good to now an approximate burn time on these canisters.
titan90000 you bet! Glad it provided some info. I will be using this fully for the first time for my backpacking trip this weekend, and I'm looking forward to using it!
Ran way longer than I thought they would.
Great vid, thanks.
Ok now this is the best video review I've seen jet boil
I love my JetBoil... I wouldn't trade it for ANY other burner.
Cheers mate! Very helpful. I'm bikepacking 1 to 2 weeks and this vid has answered all my questions. I reckon I might even be fine with a 4oz!
4 oz will get you at least 18 boils with a bsr stove (2 cups) and a plain pot. If time is not an issue and you use a good windscreen, you can go higher. In any case, you have temp, elevation... and so on as variables so there is no hard and fast number, but even an relatively inefficient stove only uses about 6.x grams of fuel per 2 cup boil. If you get a more efficient system, then you use even less fuel.
My ride was 6 months ago, but thanks anyway. I ended up taking an 8oz (220g) canister simply because no one near me stocked a 4oz. I used a Soto Windmaster(no screen needed) with 2, sometimes 3 boils a day of 3 cups each(750ml), 1 cup for my coffee, 2 to rehydrate my meal, I got home after 8 days with about half the can remaining. Truth be told, after about day 2 or 3 I realised boiling wasn't necessary as I had to wait too long for the coffee and meal to cool down to drinking/eating temperature, so remaining days with shorter burns extended the can life. ruclips.net/video/hm9AGQCj3L4/видео.html
Thank you for doing this, can't have been much fun in the rain.. Really useful info for us and nicely shot too :)
Really interesting, they went longer than I expected.
I know right!?! A few years ago I was talking to an AT thru hiker here in Maine. He said he was only on his 3rd (4oz.) fuel canister for his jetboil. Having seen this, I now believe him.
I was thinking the same thing. Pretty damn impressive how much energy is in a littl canister
Use a reflector always worth the weight. It will be altitude and Temperature dependent. Great instructional video. Keep them coming.
Just from observation, the Jet Boil timed at 3:35:00 and the Cook Stove timed at 2:25:00 according to your timer. But i notice the Cook stove boil water quicker and emits a bigger stronger Red Flame in the beginning. in conclusion, i'm thinking the Cook Stove BTU is higher than the Jet Boil given the weather, temperature, and Fuel Canister even in the Test Environment.
But good job doing this since i'm always curious as to how long these small little canisters last and how many to bring during a week long backpacking trip.
Thanks for saving me 10 minutes!
Popeye Sailorman yeah ok, but you didn’t factor in the radiator fins on the jetboil and the surrounding atmosphere protection to stop heat loss that’s built into the jetboil.
nice. jet boil is a little more bulk but kind of pays for its self in fuel savings.
Great demonstration. So cost wise, this is faster boiling and will get more burn time than the solid fuel Esbit for 5 bucks. And, over time, these will save more money on fuel cost thus paying for the cost of the jetboil. Cool.
The Optimus cook pot with the heat exchanger like the Jetboil is much more efficient.
I get boil times very close or better than the jetboil and not having the crux turned up so much.
Personally you should have both types of cooksystems, even having the jetboil mo system is still not the best all around thing to have.
Having a burner with a wider head is much easier to actually cook with, even thought the optimus burner doesn’t regulate as easy as a JB mo, I tend to favor my optimus set.
That is amazing and definitely should be in any survival or camping pack. You could cook anywhere, even in doors im pretty sure. Neato.
Look at you... With your frog togs, you're a Doctor... With this test you are a scientist...
Seriously... interesting. Thanks for sharing, take care.
RedWhite&Blue 78 Haha man only if I was really that smart! But I gotta admit I do like testing things out so we all could benefit somehow
I live in Washington and use my optimus year round also a msr pocket rocket both fantastic. Thank you for your awesome review and pimptastic music
boy named sue my fellow Washington homie! I heard nothing but great things about the pocket rocket, I think I’ll be getting one soon too 🤙. Thanks for watching !
Good info man I always swap em out too early
Kevin Chon same here bro. I just don’t want to risk it going out when I’m trying to boil some ramen lol
You're assuming that the efficiency and burn rates don't change as the canisters burn off. BTUs per unit of time would be a better measure. Interesting test, though.
Finally! Someone made a video with content that makes sense. Great job!
Agreed!
Interesting video. You didn't address the decreased pressure towards the end of the canister. It is easy to see that the flames looked different. In my experience it can take much much longer to boil at the end of a can, so I think 48 boils is quite a lot more than you would actually get.
Tip: Pack a small sharpie marker, after each burn put a mark on bottom of canister to keep track of how many burns are left.
Good informative video. Glad I watched.
I don’t use one of these. I have a stick stove but I was always curious about these.
NYZ Outdoors thanks man! You should check them out just in case. Stick stoves are awesome too, but there are places where it’s hard to find dry sticks where I’m at.
Excellent I carry msr windburner and pocket rocket on backcountry hunts in the frank of Idaho and if late season the white gas in msr Xgk which I only take when temperatures are 0deg or colder as it’s loud as a leaf blower
Soon as you saw the bottle frost up you knew it was using way more gas than the other. I do like the jet boil but the extra expense for it I’m just not sure, but now we know you after a while it will pay for itself because it uses less gas. Thank you so much for taking the time and expense to do this.
Where was the eye candy in this video lol.
Safe safe and take care.
wizardorlegend yeah it’s good to take into consideration the long term costs. Hope you find the right one for you🙂
And eye candy will be coming soon in a video, lol
Thanks!
wizardorlegend, it seems like your logic is unusual. It takes a certain amount of fuel or BTUs of heat from the fuel to boil a measure of water. The Jetboil clearly had a smaller flame and was burning less fuel per minute while the Optimus was consuming more fuel per minute and producing a larger flame and more heat. A larger flame indicates burning more fuel which you understand but you missed the concept that it will boil water quicker thus requiring less time burning fuel. Both burners started with the same amount of fuel supply. So you have a smaller flame with longer burning time or a larger flame with less burning time. In the end, the same number of BTUs were released. They likely are both pretty much equally efficient. You choose if you want more heat and a quicker boil or less heat and a slower boil. I think a better test would be to test both burners while at the exact same level of gas release. All open on one burner allows a lot more gas through than all open in the other burner.
Microarmor007 I agree with what your saying completely, I’m going off in the video it took 3 minutes or so and both where boiling, as you say it will take a certain about of energy to make that happen. The jet boil did that with the smaller flame and it ran for an hour longer. The other burner put out more btu’s due to the larger flame and the fact it didn’t run as long, but the water was boiling at roughly the same time so a lot of those btu’s were wasted.
I think this is down to cup design myself, those fins on the bottom absorbing more heat or letting less heat escape.
The Jetboil has metal find on the cuppart I believe and that is supposed to help with absorption of the heat. More surface area to transfer heat through. So jetboil might be able to use a smaller flame in conjunction with a better heat absorption method to just be more efficient overall when paired with the included cup. Some people don't like the large size of the jetboil for backpacking, but it certainly has it's uses.
Sorry, metal fins absorb the heat efficiently
Interesting experiment having worn out my second jet boil sol, and having a few stoves and pots I decided to try a titanium pot verses aluminium pot verses the jetboil sol pot using the house cooker/stove top to see how much diffence the pot makes. The result was
4 minutes for the jet boil pot to boil, 41/2 minutes for the msr aluminium solo pot to boil and a surprising 6 minutes for the titanium snow peak pot to boil. Heat conduction through titanium is very quick so I guess it dumps heat fast.
I suspect that the crux was more affected by wind than the jet boil so with a wind shield would be closer to the jet boil time. I'm thinking the pot and pot stove contact is the most important thing when considering how many gas canisters you need to carry.
Happy trails from the UK, other opinions welcome.
hmmmm I think you would have found that the boil times would have increased dramatically as the cylinders emptied. Not sure you would have archived the 71 boils that you state. I've had several different gas stoves and the boil time on all of them has increased as the cylinder becomes emptier.
Liberal science
My jetboil minimo sort of overheated and the plastic around the valve became a little burnt and loose. It still works but for a stove of this price I expected more. Ir happened within the first year and I only used the original can. Heard from other people about the same problem...
Personally I don't obsess over this, just 3.5 ounce micro burner and canister. Also have Esbit stove, use casserole type pan to disperse heat will boil some water, use baking soda to remove soot. Ultralite Alcohol Stoves I have all but dismissed as finicky and dangerous, but cat can type would consider under limited conditions. Use lot of tin foil for rehydration etc.
Nice video, but I'm more concerned with the number of times I can boil water. I've tested my Jetboil and Pocket Rocket II and they both used about 8 grams ff fuel to boil two cups of water (~70* water). I can expect about 8 boils from a 100 gram canister and 28 boils from a 230 gram canister. I weigh them when I get home and write the remaining amount on the side. Now, I would never go on a trip without some cushion, but this will get me in the ballpark.
Sweet! 50 to 75 uses! Very helpful!
Should have used the Optimus windshield and a heat exchanger pot on the crux.
On low heat with a heat exchanger, my crux boils 300ml water in 1 minute 48 seconds.
Nice to know roughly how long it will last though.
Like the music, and editing. Well done.
Daniel Asmus thanks!
Great I have these for, what ever happens. Good to know on the timing
Huge Crux fan here. Great for thru hiking. Awesome to know canister total time. What altitude were you at?
The Jetboil is optimize for heating water. How good is it for cooking with a pan on the same burner?
The nerd in me likes this!
Im a long distance hikeer. Got my cpap setup with a three day battery under 4lbs. What was your total weight with a solar option. What was your total weight.
Interesting comparison. Thanks for thinking "out of the can!"
AnOldManInTheWoods zing! Haha thanks
So you are saying that the Jetboil uses fuel faster expending more energy and would have to heat something faster. Jetboil it is, Thanks.
Hey man thanks for the time you took to do this. I don't give a shit what everyone want to argue about what it showed me was how long these last regaudless what stove you use For me going anywhere for a few days to week, I know I would never need more than1 for myself and maybe two if someone was with me. Im actually really surprised they last that long. That was always an unknown fear of running out. I wouldn't never even come close. Again Thanks
After 3 min both stoves boil the water, but which one was faster? Where they both exactly 3 min.?
I just wanted to know how to make sure that the fuel/gas doesn't leak after cook. How to know to safely keep the canister for storage after cooking. Thanks
you can switch off screen saver blackouts in settings to "never" (just for the experiment)
very informative. I was trying to find out how long the gas would last.
These test are based on the size jet they use. But average is around 3.5 hours on high. Which is good enough for 5 days..per container.
Love this! I was just wondering this yesterday and boom I find this video in my feed.
The optimus would have boiled the water even faster with the original pot, it has the same base as the jetboil to distribute the flame evenly. The jetboil is just so large and clunky. I don't know, even with those results I'd still go with the crux. Thanks for the info, I had no idea they would last that long.
Great comparison and video. Thanks for sharing.
How can you touch those hot stoves bare hand?
Different spin on your regular videos! I enjoyed it though! Nice work.
wyatt thomas thanks man. I figured I’d throw a few experiments in here and there 😉
Ok I have not seen the end, but the frozen condensation means the pressure in the tank is dropping faster, I'm guessing that will be the first to go out
I was right! Of course the jetboil will be more efficient, the pots are designed to capture energy better
Tony Rueb yeah, I didn’t realize that the cause was rapid pressure change until now. Great observation 👍
This test was not accurate. Both stoves reduced power after canisters become cooler and froze up especially that Primus system. It would take much longer if you would try to boil those same 2 cups of water after canisters froze up. Stoves run on reduced power and fuel consumption(per minute), therefore it took longer to use up those canisters than it would take if canister temperature did not drop as much.
Much more accurate would be to weigh canisters before and after boiling those 2 cups of water, for more accurate results boil 10 cups on each canister. It takes about 6 - 7 grams of fuel to boil 2 cups of water in room temperature and probably 10 for that other less efficient system. So jetboil would be good for some 35 uses, and that other system maybe 25 uses.
With the jet boil you are limited as to the pot that you can use. If you want to use a frying pan, you need to come up with something that will hold the pan above the flame, and since the flame is smaller, it will take longer to fry your meal. The Jetboil needs it's own pot or will not work as well. If you only boil water Jetboil is the way to go. If you like to use pots and pans of your choice the other is better.
Can those fuel 8oz/227g cans be refilled with propane?
Interesting results. Thanks for doing the test.
I would think boil times would differ once the canisters start getting low on fuel. would be interesting to test this at 30% then 20% then 10%.. any way it was interesting to see how long these lasted for thanks for that bit of info...
I got a question I'm glad you're doing this experiment number one number two when you take the gas stove off of the bottle does the canister refill or leak or how does that work I know on the green bigger bottles when I take my stove off it just seals you know screws on the screws back off and keeps the gas in
John McKenzie when you unscrew the stove from the gas canister , it locks the gas in so it doesn’t leak. You can use a portion of it at a time and store it away for later use without keeping the stove screwed on.
Now test how flame height affects the boiling time of the water. Using the full flame height might be a waste of time. I’ve found that on an electric stove using the highest rating of 8 is a waste of energy as using a 6 does the same job. And 6 causes less sticking and burning. So maybe do your test on flame height to see if your not wasting energy by using the full flame.
When I start my canister stove, the flame goes out after about 2-3 minutes (dangerous if you forget then to turn the gas off). I have to turn the gas head, till I hear a tiny "pop" like an air block going away, then I must screw it back to relight it. Then it all happens again. Any idea if its a faulty gas head or... what?
You should not use this to gauge how much you can boil. BTU/hour or throughput is important. Unless, you are in a place that defies the 1st Las of Thermodynamics. There’s is no more than 227g of fuel. It will take roughly 10g of fuel to boil water to 100 Celsius at sea level.
Thanks
Cool video. Thanks for sharing.
Backpacking With Jason you bet !
Thanks for the research & expenses, but what kind of damage does that do to your stoves?
Good test. Wondered about this myself.
I love your video editing and jazz intro
I have the crux,... the foldable one, I would half that rating from 48, to about 24-30 uses,... but this is in the field camping uses. This is how I "gauge" how much fuel I have left. Every time I use it I use a knife to scratch a line on it, after 4 uses I scratch a line across those 4 lines to mark "5" (like an inmate marking days in a prison cell). Some days you're boiling 1 cup, others it's 2, others its 3 cups of water. So on the average, after you have 20 marks scratched into your can you can start to worry how much fuel you have left... It's a good visual indicator of "how much" fuel you have left, but of course you have to keep up with this system, and if a buddy borrows it and is inattentive or uses it a few times, it can throw you off, which is why I can safely say "half that rating from 48-24" ;)
I boiled 3 cups in the evening, then two in the morning. It’s at 3/4. The msr canisters can be measured if you dunk them in a container of water. The water line marks a fuel gauge on the side. It was windy and I got to a rolling boil with the crux, so it was fuel intensive. Even if you boil beverages and meals each day you have at minimum 3-4 days
I'd really like to see this test done with the BSR-3000T stove. I'm considering running a Toaks 900ml D115mm pot with a 230g canister on the BSR-3000T stove. Compared to a Jetboil with a 230g can I'd be saving about 10ounces. I'm not as concerned about boil times as some seem to be. I care more that its effective and efficient. I'm kinda thinking a 115mm pot will spread out the cooking surface more to help offset the stoves inefficiencies. I may just order the BSR, its $15 and test it.
In terms of efficiency, nothing can beat Gsi Pinnacle Stove.
Anytime you wanna go hit parts of the wonderland trail or green water hit me up I'm down for some hiking or just relax and by the White River
I would of thought the crux would of boiled quicker with its bigger flame so I expected it also to have a shorter run time. The jet boil pot design is a more efficient system. Now my question is how hot was that jet boil flame the last hour and would it actually boil at the same rate it did in the beginning? That flame looked pretty small. Thanks for sharing
Michael Butler I’ve tried using the Jetboil at nearly empty canister levels on other backpacking trips, and it appears to remain efficient in bringing the boil within 3 minutes at full power
I’m new to backpacking and I’m still getting my gear. I’m looking for a serious answer don’t judge. If you are planning to have a fire why do you need a little burner? I know weight is important for your pack and trip. But I see your fire burning behind and am wondering if it’s needed. Thanks guys
Take each stove time to boil to same temp then divide by how long each canister lasted. Seems like that would give u how many boils
2 hours 20 minutes is awesome,it takes 3 minutes to boil water I’m buying one
Wasted energy when a big fire is burning beside them , j see it's reviews. Awesome these both are amazing . Sure beats monkey around on open fire 🔥 need that hot drink or hot soup. Thanks for the vid. Great channel thank you
very interesting. do you think Jetboil is efficient due to burner design or because of heat flux? or combination of both?
nofeesh I think a combination of the heat distribution coils under the pot as well as the stove design contributes to the effectiveness . Definitely uses fuel more efficiently that’s for sure
Yeah but my big question is how long does it take for the paint on the fuel cans to dry..?
Man, I love you channel.
doomboy225 thanks 🤙
The Jetboil Flash, I do not believe has a regulator? Try a Jetboil MiniMo or MicroMO?
No regular, but the early models are able to be 100% field stripped and fixed. The newer ones are riveted, making them impossible to fix in-field & not even worth the cost in a good day.
