Antique Coleman 425 Stove Testing Out Different Fuels for Performance 

It's my pleasure

Ive recently released a video on one of the civilian editions of the WW2 model, restored.

Is the Coleman better than the Svea 123r?

One of my most intriguing memories as a young boy was watching my father fuss with and cuss at, his green stove! Lol!

Also more rural locations in the early 20th these were everyday cooking stoves.

Here to feed, I have a few new ones planned.

join the club..also addicted to Colemam stoves !

And don't forget the lanterns! Every opportunity I get I fire up the lantern...it always accompanies the portable 🔥 pit.

@@mtbse789 l lol lol.

instablaster.

Glad you enjoyed it!

You're welcome, it was a fun project.

Glad it was helpful!

And may I also add that this is the most thorough, scientific, in-depth, nerdy-cool, stove video I have ever seen. It still amazes me that people take the time to share their knowledge, time and creativity on RU-vid.

Glad to help!

You're welcome.

Very welcome!

Glad you enjoyed it!

I try to minimize fluff.

Glad I could help!

Unleaded gas can clog the generator tube. Coleman fuel has less additives

Glad it was helpful!

Remember gasoline has lots of chemicals in it.

Yes in an emergency petrol would be a life saver

Awesome. Enjoy it.

It could just be seals and marketing. A side by side comparison would be interesting.

Now you don’t have to.

Welcome!

And it works really good, it’s just like naphtha but with additives.

Gasoline being easier to find and cheaper this is good info .

It was a fair test, but not scientific. A sample size of one iteration per fuel ignores 2 crucial factors of the scientific method. Consistency and repeatability. We also don't account for several factors here like, water temperature, ambient temperature, accuracy of water measurement, wind speed and direction, starting temperature of the pot, time from throttle up to pot placement are a few. These should be measured and recorded for each iteration of the test. Again, I'm not complaining about the test, it was fair and you likely wouldn't see much variation, but some items are concerning. For instance, why would kerosene boil the large pot 55 sec slower that pump gas, but boil the 1 cup 5 seconds faster than pump gas? That alone is a HUGE red flag that would invalidate a scientific test. At least that iteration would have to be thrown out. Until consistent, repeatable results are recorded, we can draw any conclusions at all. That's why we can't rely on anecdotal data and non-peer reviewed studies. We don't repeat and review because we think tests are cheated or rigged. We do it for accuracy and validity. Career scientists run into outlier data points all the time. But over many iterations of tests, patterns will form and data points will cluster at the best result. When we get multiple outliers we investigate what could have caused it and we test those ideas to see if we can repeat those results. Science doesn't dictate truth, it gives the best estimates of what is likely true with a given data set. It get even better when we have multiple studies that produce data consistent with other studies. About the only conclusion we can come to here is that the best fuel for these stoves is likely what the manufacturer, who did a lot of testing, recommended in the first place. Fresh white gas/camp fuel/naptha. But it also is of significant value to demonstrate that in a pinch, other fuels can be used.

@@mikemorgan5015agreed, but not bad for a YT vid. I thought he should have also tried some fresh fuel since that was oldish too.

You're very welcome!

Its a great stove.

@@retrotechandelectronics If I may... Try adding a CAP or two of (yellow) HEAT to your OLD White gas and Test it!? :)

@@RVingwithG I was wondering if that HEET would help to remove any moisture in the fuel. I have a couple of gallons of Coleman fuel that's been out of a protected environment and thought about giving it a try. Thanks for reinforcing my thoughts.

Thanks.

Coleman fuel [naptha] is the standard, use that

You are welcome!

Thanks!

Thanks for the tip!

Glad it was helpful!

Thanks 👍

Thanks for watching!

Right on

How long does a stove last? I would have thought the burners would wear after a while.

He didn't use E85. He used E10, standard auto gasoline. He did show that alcohol does not work well and E85 is 85% alcohol.

@@trustme7731 Thank you for the clarification, and my miss understanding. All the best to you, for your input.

@@greatwhitenorthlife2327 Yes you are correct, the burner does degrade with constant use, but I have gotton many years of use. The outer cup will disintegrate first, but the burner will still work with a damaged outer cup. Good luck with your unit, and all the best from New Rochelle N.Y.

Thanks.

Glad you enjoyed it!

Thanks!

Just remember gas has a lot more chemicals added than whitegas, it should be used in emergency but not as a substitute.

Ok, but white gas is distilled from gasoline I think. What are the known risks of running these on gasoline consistently?

@@fishinjunky I think hes alluding to the additives in pump gas and the potential for them to affect your health. A stove-specific fuel (such as coleman) would be formulated without those.

My pleasure!

Nice… free stove

You’re welcome

@@retrotechandelectronics by any chance did you do any test on how long a tank of gas last at full power.

You're Welcome.

Glad it was helpful!

Glad I could help!

Glad to help...

Thanks!

Thank you very much!

Yeah I would use different fuels for any old reason, I stick with coleman fuel unless I have no other means.

The fuel is hydroscopic, theres a good chance the container may have lots of rust in it and should be cleaned out. The pressure is only caused by a difference in air temperature outside and inside the container. Eventually you end up sucking in water and rust fragments into the generator section.

Older gas with ethanol, would have less energy per litre, and older gas would absorb water, having even less energy density.

Good and fun too!

More on the way

Thanks.

Thanks.

I wonder if adding a bit of methanol (yellow bottle HEET) would help old fuel burn better?

Glad it was helpful!

Awesome!

I was not aware of this, but I guess that would purge off the rest as fumes, vice fuel.

Glad you enjoyed it

White gas works. But isnt cheap.

I can compare between fuels and so can you, but we cannot compare between stoves because of the variables, weather, pot metal, thickness, and other such conditions.

Glad you enjoyed it

You are welcome

I thought of it, but in a pinch nobody runs out to buy a propane adapter. that wouldnt be an emergency auxillary fuel.

Glad you liked it

No, sta bil just puts a coating of oil on top of fuel for short term storage to keep down oxygen degeneration. Like a 3 month seasonal storage period.

Thanks.

Thanks!

You're welcome!

Naphtha (whitegas) is just distilled petrol. Thats coleman fuel.

what he said, white gas is still pretty much gasoline

I used 'white gas' in a coleman lamp, I didn't know it was gasoline. And when it is first lit, it shoots up a flame like 4 feet high. I was lucky I didn't melt my face off. After it is lit a few minutes and all the parts heat up, is calms down. I didn't know camp fuel was gas - like gasoline you ran in your car. And you can't beat a coleman, they were built to last forever.

You’re welcome.

Lots have asked me to do a separate diesel video

No problem!

It’s always recommended. But good to know what to use in an emergency

Glad I could help

Turn out, even old gasoline works quite well when you need a stove to cook on.

You're Welcome.

Thanx!

I heard 30°/, camp gas and 70°/, kerosene for kerosene lanterns.

Thanks for the visit

Once its up to temperature, kerosene has no smell.

My mom grew up a share cropper, thus they didn't have electricity or running water. At some point they went from a wood burning stove to a kerosene stove and they thought they were really high class then. No wood to chop. In the 1950's they upgraded to a ranch house with electricity, but still no running water till 1969. Oh, the good old days. I think the stoves that were built to use kerosene might not have imparted such a strong kerosene taste to their food, as I would imagine a lot of them were sold to farms and people who lived in the country who didn't have electricity or city gas. I know the 'blue flame' kerosene stoves were heavily advertised in the 1920's and 1930's.

I got 3 kerosense wick stoves...they dont smell

Its not my first choice.
