When I was a Marine we used these stoves on our many trips to Greenland. We had one stove per two Marines and we bet our lives on them. They always came through. They cooked our meals, kept us warm, and dried out our wet gear in the tent! I love this little stove and bought one a few years back. They say a certain Folgers coffee container fits this stove, but I have not been able to find it. Trying to buy the original Coleman case is near impossible, so I bought a metal pot that kind of fits it. Great video! Thanks!😊
I guessing you probably had the 550B, but can't be certain. This stove has a significantly larger tank and different burner than the 550B. The Marine Corps bought a metric sh*t ton of 550Bs but I'm not saying they never bought these. Both are great stoves, the 550B is just more compact and does fit nicely in a Folgers 28oz coffee container. I was Army and carried a 550B for most of my 21 years on active duty. I still have it, and it still works great. Mine wasn't issued. I bought it at the PX.
I just purchased a used but in great shape 421 dual burner. What is the best way to store my stoves fuel tank? Should I empty the remaining fuel back into the Naptha container, or leave it in the tank if I'm not using it for months. Couple more questions, can I add fuel stabilizer in my metal container and lastly to if I do empty my fuel tank and it is stored for a length of time, how can I prevent rust build up inside the tank? Any thoughts ?? thanks
This advice will get you in trouble in sub zero temps. Use any mineral, neetsfoot, or light machine oil if possible. They keep the leather pliable in extreme cold. In a pinch in warmer weather, use what you got. Water even works well, but be sure to let it dry and re-oil when you can.
1:30 and 1:48 Correction, propane does perform well below freezing, Butane does not. Isobutane is better than Butane by 20 degrees, not close to Propane. See the below the boiling points of Butane, Propane, and gasoline: Butane: Boiling point of butane is -2 degrees Celsius (28.4 Fahrenheit). It is the reason butane gas cylinder might not work as effectively in colder weather as low temperatures make it difficult to produce gas vapor. Propane: Boiling temperature of propane is -42.04 Celsius (-43.672 Fahrenheit). It is the reason propane for fuel is considerably better than Butane. Isobutane: Boiling point is -11.7 Celsius, 10.94 Fahrenheit. In cold weather Isobutane is better than straight Butane, however not as good as Propane. Isobutane is a blend of Butane and Propane. Gasoline: Different elements of the fuel are made from unique molecules, which will become more solid at different times. You could probably give it a range of about -40 and -200 degrees Fahrenheit, with most of it freezing at -100 degrees. Also, there are debates about which grade gasoline to use in dual fuel stoves. Some say high octane fuel is better for dual fuel stoves than regular gasoline. Their reasoning, higher octane gasoline contains more cleaning additive for engines than Regular (low octane) gas which will keep the dual fuel generator cleaner longer. Coleman's manual recommends regular grade. Another debate is which gasoline should be burned, gasoline with Ethanol or without? So many questions, so little time.
Interesting point. Mostly valid. "propane DOES perform well below freezing" Not necessarily. While the technical data you present is probably accurate, it doesn't take into consideration the endothermic nature of a propane cylinder running a 10kbtu burner. the tank will frost up fairly quickly and performance will degrade significantly. For a short 2 cup boil, you're probably good down to 0F. This is why many canister stoves have the option for liquid feed by inverting the canister on a little tripod. The "boiling off" occurs in the stove, not the canister and the canister doesn't get nearly as cold, nearly as fast that way. Isobutane is generally a good balance because it allows a fairly lightweight canister while allowing colder operation. But not really cold, like your post illustrates. I am unaware of a propane stove that runs on liquid feed mode, but it would give marked performance improvement over conventional feed. Safety may be an issue. In my experience the best pump gas is the lowest octane, ethanol free gas you can find. I burns hotter and has less additives. It's the closest to naphtha of the pump gasses. I have no scientific data to support that, just decades of running multiple fuels in a variety of stoves. Your mileage may vary.
There is one Problem with this stove: If you turn down the heat a bit too far, the flame may go out, and after that liquid gasoline will exit the stove. So dont turn it down too much, and *stay with it while its in use*.
You are much too cynical. This video is a user's review. If you call this a commercial then every and any product review on TH-cam you would classify as a commercial as well.

Excellent Review. Right to the point with the specs and what we need. Sub'ed.
Awesome video!! Great review! Keep ‘em coming!

Nice review on the stove. Stay safe my friend
To keep the pump leather lubricated you can use Chapstick

Only better stove out there is the msr whisper light international but the 533 is my go to camp stove some times a pack stove

So dont turn it down too much, and *stay with it while its in use*.
My coleman is way more durable than my msr international. Especially the pump.
Yes, but it is a brick and not half as serviceable in the field but it’s still a cool stove
The stove is designed for something that doesn't fit over the top. Try a smaller coffee pot or skillet. And then do a report.
