During the preparation of our journey we checked out an army surplus store. Here bought a sturdy aluminum navy frying pan and a waterproof storing box to put on the Land Cruiser’s roof. We hadn’t talked about what cooking equipment we’d bring. We wanted to keep things simple and didn’t want to build a kitchen inside the Land Cruiser. We wanted to be able to cook inside as well as outside.
I was scanning the shelves when all of a sudden my eyes fell on a couple of rectangular, green metal boxes. When I opened one of them, I knew we had found our kitchen set-up. Two old, 425F Coleman stoves were stacked between a number of military diesel stoves.
These old Coleman models, with the fancy red tank, appealed to us so we bought one. On the
The Coleman Stove – What Fuel to Use?
With my friend
In the meantime I was in touch with Coleman Benelux to get more information on this particular stove and to find out if it would run on normal gasoline.
“No sir, this model only runs on Coleman Fuel.”
“Well, how am I supposed to find Coleman Fuel in, for example, Pakistan?”
“I don’t know sir. Maybe you can take a supply with you?”
“A supply for two years! Isn’t there a way it could run on gasoline?”
“I am sorry sir. That is just not possible.”
The man left me baffled.
There must be some way to solve this, I thought, and contacted Coleman in the US. Here, I got a completely different answer. I can’t find the email anymore, but the overall message was that our Coleman stove could burn any fuel.
However, the cleaner the fuel [Coleman fuel or white gas], the longer the generator [the long tube over the flame which turns the liquid into gas] will stay unclogged. And when it does clog, you will either have to replace it or clean it.
Secrets to the Coleman Stove’s Maintenance
With that answer I felt pretty confident we could use the 425F with normal gasoline as long as I kept tabs on the generator and cleaned it regularly.
I replaced the valve assembly once, in 2007, and we used 3 generators in 9 years. To clean the generators I bought a .22 rifle cleaning kit in Bangkok. It came with 3 different brushes and they fit exactly inside the generator pipe.
I let the pipe soak in some brake cleaner for 24 hours and use the brushes afterward. To clean the spring and the needle I use a wire brush or a piece of steel wool but am careful not to damage either the tip of the needle or myself.
We got a great tip from our overlanding friend Mario. His secret was to put in a dash of injector cleaner with each tank filling. This has helped to reduce the clogging of the generator. The injector cleaner has become a regular item on the shopping list.
The Mutual Enemy of the Land Cruiser & the Coleman Stove: Rust
As said before, we have met other overlanders on the road who use the newer, 424 model with the gray tank, which is designed as an unleaded gasoline fuel burner. Many complained about the difficulties of getting it running and, moreover, how fast it rusts.
I will admit that the Coleman stove isn’t like a normal propane or camping gas where you turn the knob and have a regulated flame. After preheating the generator, getting your flame to burn nicely with blue flames (instead of orange) requires the right pressure.
And while altitude and fuel quality have great effects on the blueness of your flame, once you get to know your stove well, I find it not that hard to manage (Karin-Marijke doesn’t entirely agree with me on this).
After 7 years on the road we hit the tropical Amazon forest. Only then did our red-tank 425F model seriously start to rust with holes falling in the bottom.
I’m amazed that you can still find the original red tank f425 on Amazone once every while, brandnew, as if they are still being produced.
Fortunately, by that time my brother in law Fred had sourced the above-mentioned, a like-new, 424 model on a flee market for next to nothing. And that’s how we got upgraded from red to gray.
Why a Coleman Stove?
We love our Coleman stoves and would like to sum up our pros for you:
- It burns really hot (compared to cooking on gas).
- I like its simplicity of dismantling and cleaning.
- We can buy fuel everywhere.
- It works on all altitudes [nozzle doesn’t freeze].
- It’s mobile: we not only can choose to cook inside our outside of the Land Cruiser, but we even took the stove on a glacier trek in Pakistan.
And of course the cons as well:
- It needs getting used to (Karin-Marijke is still in that process…).
- It needs regular maintenance and cleaning.
If you have any tips on using these stoves, I welcome you to do so in the comment section below.

I just received an email from Dave where he says he is experimenting with the making of white gas. Very interesting stuff. Some of you might be interested as well so I thought of sharing his initial video.
Part one, with more to follow I guess:
I found some nice little movies on how to best clean you Coleman Stove. It’s in three parts and I will add them below.
Coleman Stove Maintenance and Additions
Sometimes there is no time to clean your current generator. That is why we always have a spare. It is best practice to keep at least one extra generator at hand. If your current one is clogged or is otherwise giving you a hard time to get a good blue flame, just exchange it for the new one and leave the used one to be cleaned for later.
Fuel Injector Cleaner
Whenever we fill the Coleman tank with new fuel, we make sure to add a dash of injector cleaner. This way the generator will stay cleaner much longer. It does not prevent the buildup of carbon deposits, but it will greatly slow down the process, thus the generator will last longer.
Pump Cup Replacement
Over time the little rubber cup of the pump will run dry. Remove the plunger and add a little engine oil on the sides of the cup. Being in a gasoline environment it is normal that the rubber will degrade over time. This leather replacement cup will end your pumping troubles for ever.
Putting together information pages like this cost a huge amount of time. I’m happy doing that and spreading the good vibes for traveling the world.
