MSR Whisperlite Universal VS Optimus Polaris!

[@dt719]

Great review! I just bought the Polaris after using my XGK for 20 plus years. Your reviews really helped with the decision. The final deciding factor for me was the fuel pump and ease of switch between gas and liquid without changing parts even if efficiency is compromised a little. My XGK still works great but I'm on the second fuel pump after the first one cracked.

[@jiujitsu2000]

Great decision. Thank you!!

[@johnmellor3048]

Nice review. Looks like both are good stoves. I have no direct experience with Optimus but have had to deal with MSR on a tent issue I was having. They were super responsive and solved my issue promptly by sending new stuff free of charge. At these prices, it is good to know what kind of CUSTOMER SUPPORT to expect if something does go wrong.... something as simple as email response time to a random question might be included as part of a review(?) PS - I believe it would also be valuable to weigh the fuel bottles before and after to see how much fuel was burned in the process.

[@litchoutside9812]

Excellent and fair review- Thank-you. I ended up retiring my Coleman multi fuel stove as I could not get parts. It served me well for 28 years. I went with the Optimus Polaris to replace that because of longevity possibility with the non-plastic construction and ease of use. Thanks for doing what you do to help folks make good decisions

[@thomaslubben2021]

I wonder if one reason the MSR boils faster is that the larger, broader flame transfers heat over a wider area, and hence more efficiently. A small, hot flame will show signs of localized boiling sooner, but the overall heat transfer with a broader flame is, in the end, more efficient. That would indicate the broader flame of the MSR has multiple advantages in the real world- not only for pancakes, but also in fuel use. If the MSR had a controllable flame like the Dragonfly, maybe it would be an overall winner.

[@ralphwatten2426]

I adapted my MSR International to run all fuels including alcohol. Took a little doing but it works great on all the standard fuels for the International and butane/propane and alky changing jets and air mixture adjuster. What I don't like about my MSR is the pot support is too big. Japanese bikes with constant velocity Keihin or Mikuni carbs didn't need to change jets at altitude. The carbs compensated. When my cousins Harley was gasping in Colorado the '81 Gold Wing purred like a happy kitten.

[@Radoslaw731]

WTF are you taking about 😮are you insane 😅

[@andrzejwojcik47]

Great test. I already use Optimus Crux for ultralight backpacking and I am super satisfied with the quality of it. I also used MSR PocketRocket which I found a very simple and robust tool. I believe and I am trully confident that both presented stoves are super awesome but I would go with the optimus here. I look for a small car camping stove where weight is not an issue, noise I can survive. With a small kid on a camping I prefer to have one settings for all types of fuel, good support on the ground and possibility to acommodate different sizes of pots from small to large. As of the test itself - lots of details and useful information. Very professional.

[@jiujitsu2000]

Excellent stoves!

[@oyvindidland5775]

Great comparison! Been using Optimus myself for years (with a Trangia adapter). MSR seems to do better on performance, but I suspect that on the small kettles in the field, the difference would be negligible.

[@arildschonberg3607]

Exactly! And in the field, you cannot use the higher energy, without burning your pan or casserole. Only when boiling water in a steel pot, the higher energy could be useful.

[@peteaustin9636]

that was one of the best reviews ive ever seen ... good drills .... msr for me as there are less things to go wrong... you called it right

The jet cleaner function shut it off because it occludes the gas flow. It is meant to be used when the stove is off. Great comparison!

Hello there. I’m a new subscriber man what a test. I watched the whole video. It was long but it was worth it. I went to my local REI and bought the MSR Whisperlite stove. I have been reading about it but spending over hundred bucks was holding me back. After your review I went and bought the stove with other accessories I spent $234.00 and didn’t phase me. Thank you for sharing the review. You sealed the deal

[@TheZoeybear]

Thank you for your videos after watching you do the review I decided to get the Optimus Polaris ! I like the fact that you can use different fuels and not have to change parts out . Hopefully more videos to come from you for Polaris

[@FT4Freedom]

This is a great benchtop review. I highly suggest people consider their type of outdoor activity before they buy a stove. Are you in low wind conditions? Are you at cold windy high elevation? Consider the burner design and efficiency with and without wind. If you are mountaineering in cold windy conditions you may find that the MSR is not the most effective stove.

[@jiujitsu2000]

I'm in Northern Arizona high desert. It's windy here. Thank you for the kind words and support 🙏

[@KE4YAL]

I have had an Optimus stove since back in the 70’s very reliable i can go get an put in my backpack an not have to worry about it not working I can’t say anything about the MSR I never tried any of their products Great video thanks for sharing

[@jiujitsu2000]

Thank you!

[@carrdoug99]

It's hard to argue with the results, but I'd have to go with Optimus. Two reasons. If it's possible to loose fiddly bits? I'm your guy. One thing I really don't like about my whisper light is how stiff the line is going to the stove. When your limited for for flat spots like on rocks, it can be real bugger keeping the stove portion where you put it (at least for me). The Optimus appears to have a more flexible hose. Thanks for the in-depth review👍

[@RocklandRednecks]

I certainly am going to add the Wisperlite to my wish list. The Polaris is $50 more expensive here in Canada. I prefer the pump construction given the showing in this video but its not worth the extra price. Love the versatility of fuels too great for survival or traveling where fuel sources are unknown.

[@slaphappyduplenty2436]

There is possibly a plus side to the noise of the Optimus. I haven’t used the MSR, but with the Optimus I can do other things around the camp and know that everything is ok with the burner. If there is a problem, I’ll hear it. With a few other options I’ve tried, I feel a constant need to check on the burner. That said, I do find the noise annoying.

[@danielszucs267]

Thank you, a great review video! Maybe that would be an additional point, if before and after the test you would measure the weight of the fuel containers. From the difference before/after we could see how much fuel is used. That would be a really userful. :)

[@carlospena9196]

The major difference (and deciding factor) between whisperlite-style liquid fuel burners (wide, shallow/exposed, flame dispersing) and xgk/dragonfly/omnifuel-style liquid fuel burners (narrow, recessed, flame concentrating), is the ability to melt snow/boil water rapidly in very cold and/windy conditions. The latter burner style (omnifuel/xgk) will win every time, hands down. I know from experience, with 10 day winter expeditions in mountainous areas and in sub-zero temps, folks who used the xgk were melting snow and boiling water much faster and therefore conserving fuel. Whereas the folks using the standard whisperlite were taking much longer to melt snow and boil water given the adverse environmental conditions; to the point that their fuel reserves were running much lower. Low fuel bottle reservoir (big air headspace in the bottle) adversely affects whisperlites in a way that compounds the problem. You need to pump the bottle more to maintain enough pressure to keep a strong flame, which means the stove is consuming more fuel. It doesn't take much pressure to maintain a strong flame on xgk-style buners. If you're not planning to take your stove on high altitude or subzero trips for extended periods, the whisperlite was preferred for price point, simplicity and cooking versatility. Since the advent of precision flame adjustability of the dragonfly/omnifuel style liquid fuel stoves, they have become the more versatile option since they'll perform well in all conditions (for melting snow, boiling water and cooking). The only downside is the noise. Personally, I'd only use a liquid fuel stove that performs well for melting snow/boiling water/cooking everywhere in every condition and with every fuel, for extended trips with a group of people since liquid fuel stoves are bulky and heavy. If I'm traveling or cooking solo, in relatively mild conditions and/or shorter trips, I prefer a lightweight/small pocketrocket-style stove.

[@russelljackman1413]

Very well done! Thank you for going into minute detail for us! It really helps. Thanks again!

[@tomhildebrand2656]

I have both along with many others. A couple things I have noticed. The optimus fuel filter clogs more often for me. I prefer the optimus pump. It just seems tougher. Neither fold up great, but the Polaris seems a little better. I also have a primus multifuel which seems like another excellent choice. In the end I can say that MSR warranty and customer service are top notch. Parts are also pretty easy to find. I am bothered by the fact that MSR pumps only work on MSR fuel bottles where both of the others mentioned seem fine with any as long as threads match. Probably just made the choices tougher!

[@VansWorld]

I’d probably be happy with either one. Great detailed comparison 😀👍

[@jiujitsu2000]

Thank you! They're both EXCELLENT!

[@andrewmcgaha9629]

I know, necro-post, but I have to comment... Found this video as I am thinking of consolidating to one stove to rule them all solution. I have an MSR XGK II Shaker Jet that I have had for +/- 25 years. I used it mostly for making Ramen while training in the Army. In those 25 years, I have rebuilt it once, I have run every possible kind of fuel through it, and it has never (not once) failed to function. I purchased a Nova + around 5 years ago. Both stoves were run with white fuel at that time and have sat since. They sat as I played with alcohol stoves, and canister stoves for awhile. Anywhoo... I went to fire them both up this past weekend and the MSR started right up, but the Nova + will not get fuel. The canister is pressurizing, and I removed the filter on the Nova to make sure it wasn't clogged, and fuel just does not get to the bowl. I've disassembled and cleaned every component. Not looking for advice on getting the Nova started, and I prefer the ergo of the Optimus, but in a limited sample, the MSR gives me much more confidence. In your experience is the MSR more reliable, or do I just have a lemon of an Optimus.

[@jiujitsu2000]

This is an excellent comment... The MSR stoves are fantastic and very easy to maintain in the field. I found that the optimus Polaris and optimus Nova have the same kind of reliability. I'm not a big fan of the Nova +... in fact, I sold mine.

[@gregpowell7097]

People comment on the plastic pump on the msr vs the metal pump on the Polaris, but the plastic on the msr is pretty thick gauge plastic, I can’t see it failing. I want both but I went with the Polaris as my first multi fuel stove. Thanks for the in depth review. I also worry about losing that shaker jet tool.

[@paulnam4488]

Only 1/4 through this video and already gained some useful insights, some of which I've confirmed over the years. My own experience, howevver, is only with older Primus and MSR stoves in 70's and 80's. The refinements in the newer stoves are great, however I find the increasing reliance upon plastic materials potentially disastrous in the long term. My old Primus has sprung a hose leak at the pump end and I'm going to repair it this spring. All of the hose fittings on stoves old and new are an Achilles heel. Watching a lot of stove videos i realize that every time a stove is used, the hose fittings get a lot of exercise, sometimes too much.

[@geraldhenrickson7472]

Operating a gas stove at too low a level is the very best way to clog/soot up the main jet. Shaking the stove may or may not clean it sufficiently. Just something to keep in mind. Thanks for the video.

[@jiujitsu2000]

Excellent comment, thank you

[@waynerenshaw-multi-outdoor4521]

Great video, OK I have the Optimus Polaris and 2 things I noticed with your video, on the fluid when you were doing the test I noticed the Optimus was fluctuating this is due to low pressure in the bottle, on the gas when you use it in gas mode it doesn't kick out much, but if you stop the gas coming through then turn it into winter mode then relight it, it actually gives much more power, I noticed the MSR did it automatically, and I think the Optimus Polaris if you switch it off then turn the canister over you'll see a massive power, I boiled 1ltr of water and took 2mins 34 seconds 👍 try it out and you'll see the difference from gas mode then switch it of then turn canister over a relight it, then watch the power kick out extremely more aggressive 👍 😀 great vid 👍

Thanks for the videos - I was going to go with a dragonfly for the flame control but started to look at other companies as well - All the stoves with good flame control just seem to loud and to spend another $50-100 to silence them is a bit much. I just purchased the MSR WhisperliteUniversal since it's quite and if I need good flame control I can use the isobutane fuels - I also have an adaptor to attach to a propane canister that works with my other mini stoves so should work with the whisperlite and add one more possible fuel source. Keeping in mind this will also be used car camping - but will be available for some backpacking trips - Never thought I'd be so hard to decide on a stove! Thanks Jiu-Jitsu 2000!

[@tomkipp66]

Looks like the 2 pumps are able to run on either system so you can use the Optimus pump with the MSR stove since you like that pump better…just a thought…i just purchased both of these systems tonight looking to see what other things can be used from both systems, like jets maybe or whatever, might be able to swap things you like from one to the other and make your own personalized stove, what great fun… great testing.

You have ran a perfect comparison of the two stoves.. My personal opinion would go with Polaris because of not having to change jets. I go into deep snow and if I was to have to change in these conditions not only do I risk loosing them but also freezing your hands. I have questions on this.... I have the optimus nova. Works perfect... No problems what so ever at minus 30 Celsius degrees in LAP LAND SWEDEN. BOTHE THE NOVA AND POLARIS BURN SAME FUEL EXCEPT THE POLARIS WILL USE CANISTER GAS. CAN YOU BUY AN ADAPTER HOSE LIKE THE ONE ON POLARIS THAT WILL WORK WITH THE NOVA. Many Thanks for any info you provide..... Again a great video on the comparison. You did it the correct way.. Don't listen to some of the smart ????? AIRBORNE

[@jiujitsu2000]

Thank you! Yes you can buy a Polaris hose and it DOES fit the NOVA,,, BUT... The nova won't burn canister fuels until you change the jet to do so...

[@jamesvanderwoude5705]

Really like the test you did for comparison. I have had the MSR for over 20 years and bought the Optimus 5 years ago as a back up and to be able to quickly cook something with out having to prime and use a canister. You came up with the same results that I have experienced in the field. I carry both but love the quiet of the MSR.

[@geoffnepo]

Incorrect, by reversing the gas bottle orientation you would draw out all the remaining gas vapor from the line before shutting it off at the pump and at the burner. In my opinion Optimus has more robust components compared to MSR along with some of the unique feature built in to the design

I am late to the party, but still wanted to say thanks. I have the Whisperlite, but just purchased a new (old stock) Optimus Nova+ and fired it up today. Whatever the last model was before discontinued. Same basic technology as the Omnifuel from the generator onwards. Anyhow, I was viewing to see if others have that unstable fluttering from the jet, and I have to say yes. Just how the jet is designed I guess, nothing unusual with mine. Unstable sounding, but also like a fighter jet engine or something. Different from the smooth hiss of the whisperlite I was used to. This video is very helpful for many reasons - excellent job.

Nice and complete check of the 2 stoves! Well done, thanks! It was a surprise to me that the msr had been faster at boiling because the technical data of the stoves tells that the polaris have a higher amount of power (4200W at gas) than the msr (2990W) in the data sheet! In that way it tells me, the practical check you have done is very useful and neccessary! I got the polaris causing the very robust standing but both stoves are nice ones

[@cubul32]

"You give the shove a lil' stake" - the best line almost said ever in a review.

[@greeny5155]

The liquid feed problem isn't actually an issue with the Optimus. Before turning it off just rotate the bottle so that the OFF is facing up, you then wait for a little and the valve being on top now pushes the rest of the fuel through and depressurizes the canister. Then, once there is no longer a flame, you're good to turn off the valve and know that there is no more fuel left in the line.

[@truthseeker104]

Somebody tried a test by swapping the fuel line from a Nova to a Polaris and vice versa, apparently the pulsing sound happens on the Polaris with either tube but doesn't on the Nova, the Nova was an older model. So I guess that the pulsing sound must be due to the generator design. I have found that the Polaris has less of a pulsing sound when you put slightly more pressure in the bottle. We also wondered whether the fuel line makes a difference as the aperture of the Polaris is less than a Whisperlite so this possibly makes a difference in respect of fuel feed and heat output, so increasing the bottle pressure a little will compensate for this. We wondered also whether the Lindal connection would impede fuel flow as it is designed originally for gas, and I questioned whether MSR had made the connection replaceable because of this. Apparently the narrower Polaris tube does have an impact on heat output when used with the Nova as I guess the tube must be narrower as I say. Also to end I have found a round old style MSR washer much better on the fuel bottle as the flat washer supplied leaked unless the pump was ridiculously tight, it is an Optimus bottle I have been using so theoretically should be ok.

[@larsleion]

Great videos, man! These have been great for deciding which stove to get. Maybe you can answer a question I have been wondering about regarding the Optimus' fuel tube in the pump. I have read (in one review) that the fuel tube might not be bent enough away from the center so that end stays firm to the bottom of the bottle in ON-mode and to the top of the inside in OFF-mode. The problem then being that the OFF-mode doesn't really work if the bottle is above half full, and that the fuel tube is unable to reach all the fuel left when it's nearing empty. Yours seems more bent out than most I've seen in videos and in person. Have you ever experienced this problem yourself? I'd also like to hear your thoughts on the issue. Thanks!

[@anhatur]

Fuel effeciency has a flipside that worries me more than the fuel consumption: Carbon Monoxide emissions. Fuel burning at a lack of oxygen means CO emissions, and I mostly use these things for burning kerosene, being at the heavier end of the spectrum. During winter, wehrn It *is* tempting to bring your stove inside the tent. I haven't done it yet, but have considered bringing one of these CO alarms to see how high it gets. And if you're that serious, fuel efficiency is a priority. Plus, my wife likes a silent stove. So it's Whisperlite for me. I wonder ihow well it works to run the stove at low pressure for simmering, but I can always bring an alcohol stove for that. It's a good backup anyways.

Fantastic video. I watched the entire thing. You were thorough and most importantly you were fair. I love the enthusiasm. Lol there aren't many significant others that would understand our interest in these things but I digress. I went with the Optimus Polaris with the quiet cap. I'm thinking along the lines of I get to camp late, Its dark, I'm cold, I'm hungry. No need to waste time changing fuel jets, which in all likelihood is a job only one member in the group (you) will be able to do. No risk of losing a piece in the field, better stability, smaller pack size, better looks, ability to use smaller pots and what I find is better overall controls, features & build quality. I love MSR, especially their guardian filter but in this case the only real advantage I see in the Whisperlite is the ability to clean the fuel line if it gums up. That's it. The boil times, I find are already negatable with only about 2 mins difference and only seconds apart when boiling smaller amounts. In my opinion the Optimus wins in simplicity and worse case scenario. "honey, I broke my wrist on that fall back there & I need you to change the jet on the stove...."

fuel efficiency was the deciding factor for me. dont get me wrong the optimus has some much needed upgrades over the msr but i really think that fuel efficiency would serve one better over all. the ability to clean the hose and the filter not clogging all the time is very nice as well, assuming its a larger micon filter the shake needle should take care of any issue that could arise. my decisions where based on primarily using gasoline.

[@FT4Freedom]

It depends on what kind of wind you have. The Optimus centralized cone design works way better in windy mountain conditions, it follows a mountaineering application. The MSR will have better efficiency in low wind conditions. If you are melting snow in 25mph winds on the side of the mountain your Optimus will be faster.

[@robe4037]

Optimus’ sound level absolutely rules it out. Stealth and lowest sound possible is critical in the forests. Optimus has great features and benefits - pump, flexible fuel line, stable feet, smaller cup acceptance, fuel control and no jet changes MSR - ***Quiet *** better burner heat distribution They need to start making some serious improvements I will still purchase the MSR for its quiet operation

[@robe4037]

Addendum - I neglected to include my thanks to Christian for the obvious effort and resources expensed to plan and execute this and the other videos. Great job

[@Exstaz]

Getting a polardawg from imaterialise will make it quiet and give you even better flame control. Quiet stove just copied polardawgs work so I would not support them.

[@paulbirch7635]

Great compassion! One question though, how does the optimus compare with the fuel filter in the pump? I am the first to admit that I enjoy to modify things. Stoves included. So I have set up a whisperlite to run on alcohol*. So it is safe to say I know my way around a WL... I've hade MSR pumps crack in the plastic on me, and that is not serviceable in the field. On the other hand the rest of the MSR stove is easily field serviceable. Hence, this is what i would do: get the whisperlite universal, attach the canister fitting and use a Lindal B188-style pump such as the optimus pump. Best of both worlds really. *Lots of disclaimers here, if you don't know what you are doing - do not attempt. O-rings and the MSR fuel bottles will deteriorate due to the chemical properties of alcohol. (Hit me up if you still are still interested :) )

[@AquaTech225]

How are u running alcohol through it

[@asullivan50i]

Both have great features, ima go with what I know too. MSR! I do like the pump and valve on the Polaris...

[@kaitensaw5992]

Thx 4 the very good comparison. I was sold on the no parts to change idea cuz I have lost parts quite a few times. But to Polaris obviously compromise on peak performance for no part changing feature. Also It cost a whole lot more, plus additional $$ to buy the quiet cap. It also does not come with any spare parts! Have to pay much $$$ just to get couple O-rings for the Polaris. In the end, while I like the no parts changing and its ability to control simmer while using white gas or gasoline fuel better than Whisper, I'll stick with my Whisper.

[@robalan57]

MSR sells a stand for the stove to make it more stable.

[@Beingkindfeelsgood]

I prefer not having fuel in line after I turn off stove just for safety reasons.

[@jiujitsu2000]

Very smart. Thank you!

[@Romin.777]

Very good review, but i'm still not sure wich one to get..

[@clayb.6077]

Thanks so much for your videos , I bought the msr last year, I should receive my new polarius tomorrow, I also bought the vega , the crux weekend he cookset, the msr pocket rocket deluxe . Both companies have great customer service, the only difference is optimus said they don't have a repair shop anymore but they can make sure we can get parts. Msr can inexpensively rebuild the stove and pump for about $30. I completely agree that you cant go wrong with either company and any of their stoves.

[@kiwideann5632]

Great comparison. I’m on the Optimus side. You can flip the fuel bottle over and drain ALL the fuel from the fuel line. You can’t on the MSR. MSR you still have residual fuel to deal with leaking everywhere.

[@bufftammy735]

Msr says Burn time (white gas) per 600ml / 20 oz. of fuel Appx. 110 minutes Optimus says Up to 100 min at maximum output (with 400 ml of fuel) Wouldn't that make the optimus more fuel efficient?

[@jiujitsu2000]

"Up to" the MSR is more fuel efficient... both are EXCELLENT stoves! Thank you for stopping by and sharing your thoughts.

[@seasoldier3902]

I found your review interesting but it was really long-winded with some repetition. However, it was comprehensive and appreciate the actual time and effort you put into its production. The Optimus stove has been adopted by the Royal Marines when deployed to Norway, in the winter months, within the Arctic Circle. Being a former Royal Marine I was issued an Optimus stove that was very simple to use but noisy as well! It also was a single multi-fuel burning stove but not gas! This was is a time when they issued Brown Bess muskets, not like the personal weapons of today!! Anyway from your review my money is on the Optimus as it is "Bootneck" proof! Thank you for your service in former times.

I love your comment, thank you so much it's spot on... blessings from Arizona

[@peterd1234567890]

what happens if you use the msr stove (with the canister flue line) and the optimus bottle because that would make the universal more "universal" since you wouldn't need to change flue line to go from liquid to gas. plus you would get optimus's all metal pump and MSR's capability to put a more efficient jet in for your preferred flue (that you could leave in and just run less efficiently) why dont see this all over the place?

[@AquaTech225]

Curious myself

[@normanmallory2055]

Wow this was really good , well done and accurate .. Which stove would i choose ? Gawd that's tough , both have their strong points and maybe weak points if one could say that .. I have wrote to MSR about my Whisperlite in the 1980's as mine had a rubber composite fuel line and they said sent it to us and at no charge we will install an metal fuel so i did .. Over the years i have had questions and used the internet and i always got an answer back to my question.. My dealer carries MSR parts..Any company doesn't have to build mtn stoves for 100 years to get it right , look at Coleman for one .. Swedish quality has always been there except for the Crux model i see that says China huh.. But for features of push and shove , small but important features , large leg pods ( one feature i do not really like on my Simmerlite so i have to plan out where to place it) plus others and throttle valve attached to the stove body for instant fine adjustments , i do like that .. I'm not saying i'm too lazy to change jets as i do this as i own more MSR stoves than any other brand and have done this many times with my XGK not really any problem and i do the change at home in my shop... Optimus... would be my choice after watching this testing which is the best i have seen yet.. Well done ...

[@kir11]

great comparison, very informative and comprehensive! Now i`m relax and going with MSR. I agreed with your arguments about MSR. Thank you!

[@GhostOfSnuffles]

IMO the Optimus is better when it comes to normal operation and the MSR is better when it comes to fixing if/when things go wrong.

[@jiujitsu2000]

Wonderful thoughts! Thank you for sharing!

[@silentmajority7598]

more often then not i modify my gear to meet my needs. it wouldn't be hard to braze, solder, weld, epoxy...bigger feet on the msr. as well as, modify the arms to hold smaller or larger pots or pans. its a tough choice. great video

[@jeriksson7686]

Can you use a Optimus bottle on an MSR pump? and vice versa

[@jeromebullard6123]

I own a Optimus Nova+, and I’ve boiled corn on the cob fairly quickly. It’s a bad ass stove. Ten years of heavy use, and never had an issue with anything. Top of the line hands down.

[@DL-ij7tf]

An additional confounding factor to head to head tests is that fuel canisters are not uniform, either between companies or within the same company. Even two canisters of the exact same brand will have variability due to a number of factors such as time of year/temperature when it was manufactured. As far as long term durability, my main concern honestly (over small differences in performance), when products are made as well as these it most likely will boil down to individual luck. Maybe a hyper-specific circumstance (a fall off a table at a specific angle) will make one fail and not the other and a different circumstance will do the opposite. Most likely, anything that will seriously trip up either stove would trip up any stove, like if you run it over with a car or lose it entirely. For what it's worth, I ordered a Polaris a few days ago :)

[@allanthompson9695]

Cool test and Video. Both great stoves. Cheers.

[@donboehner6005]

Simplicity wins IMHO. I don't want to be looking for parts and in the cold my fingers wouldn't cooperate assembling valve components.

[@jiujitsu2000]

+Don Boehner Great comment, Thank you!

[@gweedomurray9923]

Hopefully, you left on your trip with enough of the fuel you prefer and so wouldn't need to change jets. I wonder why MSR doesn't make an adjustable jet and then a simple turn of a screw is all you need for optimal flame setting.

[@digitalballistics]

How often do you find yourself switching fuel sources in the field?

[@gweedomurray9923]

Exactly ! Nice to be able to turn a screw to change the jet size while you watch for the best flame.

[@Onuiwa]

@@gweedomurray9923Old post but I'd like to point out that MSR has another stove called the Dragonfly that lets you control the flame like you can with the Optimus Polarus.

[@impermanenthuman8427]

For general use is go Polaris for ease of use, but as an emergency stove it has to be the universal. I’ve seen your vid where you burned Terpentine and how gummed up the end of the fuel line was, if you had to burn unleaded gasoline for any length of time and you had no way to clean the Polaris hose then it would just fail, plus they don’t seem to sell just the hose either as a spare part which is strange, if you could get spare hoses as a backup then that might tip me towards the Polaris, but for me I generally only want to burn isobutane and also cheap 100% butane canisters in inverted liquid feed for maximum low temp use where my winter never really gets below freezing anyway, so I would barely ever need to change the jets, and if I ever ran out of canister fuel and I can’t get any anywhere at all not even pure butane then that means life has got very austere for some reason and I’m going to need to burn a lot of unleaded gasoline and I’d trust the MSR for that on a longer term basis. Another plus for the Polaris though is that with its legs closed it fits in the burner ring of a Trangia 25 so if you prefer to burn alcohol in your trangia but run out then you can use the Polaris on the ground but up into the burner gap

[@darrylkeeler4235]

Oh man. So starting the pots with the msr basically on medium and the Polaris pretty much off while you adjusted pots before turning them up was an advantage for msr. Great review of features snd good video overall

[@phisit8813]

I'm ordering the MSR tomorrow :), I just hope it is as good as you demonstrated. Can you please do a video on camping pots ? :) thank-you

[@DL-ij7tf]

I'm obsessed with camping pots and I would recommend the Zebra stainless steel products, especially the 12cm or 14cm Billy cans or lunchboxes. I'm also a huge fan of Stanley's steel products. Inexpensive but smart and simple, rock solid and easy to find. I nest the Optimus Polaris and accessories (minus the fuel bottle) in the pot of a Stanley Two Bowl Cookset. Probably work well for the MSR too. These stoves have a fairly large packing footprint and I'm paranoid about them getting crushed and bent.

[@vansongs]

I like the wide flame of the MSR. And quiet..

[@jiujitsu2000]

Me too! The silent cap for the Polaris is VERY effective though! Both are great stoves in my opinion! Thank you!

[@IndianaDiy]

I like both stoves. I was considering buying the MSR, but then I saw the Primus OnmiLite Titanium Multi Fuel.

[@jiujitsu2000]

that's an excellent stove as well!

[@jlau2014]

@Indiana DIY so which one u prefer? MSR Universal OPTIMUS Polaris Or PRIMUS Omnilite ti? I'm still confuse to chose between them, please help lol

[@IndianaDiy]

@@jlau2014 I bought Optimus Polaris after watching a few more videos. I really like the Optimus the best, I looked at the Primus but it has a leather piece in fuel pump that could fail. I considered MSR but Optimus features won me over. In the end I bought the Optimus Polaris for reliability and ease of use features and cleaning of jet. I did buy a large 1.5 liter Primus fuel bottle and it fits Optimus Polaris fuel pump, but I haven't used that fuel bottle yet with fuel in it, I have two 1 liter Optimus fuel bottles and the .4 liter it comes with. Oh and I'm only using Primus canister fuels and White gas in my Polaris. Primus fuels seem to be better I have a case of 450g I bought from Primus and I'm also buying a case of Primus winter canisters soon in 450g.

[@jlau2014]

So tough for me to chose between them, maybe I should watch more video lol. I like the size on Omnilite ti Love how easy on Polaris with only 1jet can use all fuel and the pump but I just watch jiujitsu2000 video that he tried to run all kind of fuel on his whisperlite with only 1jet and result is good hmmm. Confusing 🤣

[@jlau2014]

@Indiana DIY this is the video make me hard to chose lol kzbin.info/www/bejne/nImWgaSnpKamjKs

[@Winnie122459]

After watching the test I too would give the edge to MSR. The magnet test kind of worried me but not so much as not owning one. I do like the pump on the Optimus because it is not plastic other than that I believe you could not go wrong with either stove. Great video on the pro's and con's of each stove

[@5USgRWFH]

You mentioned using lamp oil in the Optimus Polaris. Have you tried lamp oil in the MSR?

[@impermanenthuman8427]

I’d like to see both lamp oil and also diesel burned

[@burning4902]

great video man

[@Antwelm]

Thanks for the video. I watched it a few times before deciding on my Optimus Nova, which I love (Nova is the Polaris without canister-adaptor). Question: Are the bottles interchangable? Like, does the MSR-bottles fit the Polaris pump ? How about Primus fuel-bottles, do they fit both stoves?

[@michaelsrowland]

Are you happy with the nova?

[@Antwelm]

@@michaelsrowland Very happy. It is noisy, but that just fits the fact of burning pure petrol and its massive power. It looks like a jet engine and burns like one too. It is simple, sturdy and feels very trustworthy. More precise flame control and simmer abilities than on other stuff I'v got. I have even fired it up a few times at home on a whim, just because it is so satisfying. And, compared to the Polaris, the connector on Nova seems much more heavy duty and there is no nozzle worry, cause I'm only using the optimal fuel and if you _need_ to swap fuel, that wouldn't be a problem anyway.

[@JohnDoe-ee6qs]

you did give the MSR Stove an advantage by using a darker pot on it

[@jiujitsu2000]

Off camera I've done similar testing with the pots reveresed and the results are the same. I didn't feel that it was suggnificant enough to call it a disadvantage. lol... Thank you!

[@tristanvarsovia]

Great video and comparison, just like to know about fuel efficiency, which one used less fuel to perform?

[@jiujitsu2000]

Tris Varsovia MSR is more fuw2l efficient because you can fine tune the stove by changing the jets.

[@tristanvarsovia]

Thank you for the reply, as I'm planning to upgrade my current backpacking butane stove which is a Kovea Camp 3, to a multi fuel stove that I can also use for SHTF scenario. Your video helped me to decide and confirm my choice of getting the MSR. Thanks again and more power to you.

[@jiujitsu2000]

+Tris Varsovia both the MSR whisperlite Universal and the Optimus Polaris are excellent excellent stoves and either one would be fabulous to own
