Sports reviews of Coleman Exponent Multi-Fuel StoveCustomer Review: Fantastic White Gas Stove! Sport shop rating: 5 Stars
I just love this stove and can't praise it enough. I bought mine 20 years ago after reading a rave review in Backpacker magazine (It was called Peak 1 Multi-Fuel at the time, but it is the exact same stove as the Exponent Multi-Fuel). I use it mainly for cold weather backpacking (butane/canister stoves perform poorly in the cold); for summer I use lighter/smaller stoves. I have used this stove heavily over the years and it has performed flawlessly, reliably, and impressively.
The fuel economy is amazing and is the key to this stove. One tank of white gas (10.3 oz.) is rated for 1 hour 23 minutes burn time at full blast and 7 hours on simmer! You probably won't ever have to use it at full blast, as the flame spread is quite big at that setting (with a pot on the burner). Even with a large one gallon pot I didn't have to use it at anywhere near full blast; I usually only use it at about halfway between simmer and full blast. I also use the rectangular aluminum Coleman storage/cook pots that were specifically made for this stove (weight = 8.5 oz). They fit this stove perfectly to give you a nice compact & complete cook package (I'm not sure if Coleman still sells this, but highly recommend it if they do).
The weight of this stove (21.6 oz. empty) really isn't bad when you take into consideration the excellent fuel economy and that you won't have to take an extra fuel bottle with you unless you are on quite an extended trip. Most other white gas stoves are nearly as heavy, but don't have the fuel economy or power of this stove, so you will be lugging a lot of extra gas.
The flame adjustability is excellent too; no problem to simmer.
I have only used white gas with this so I can't comment on its kerosene performance.
The stove has been absolutely bombproof. I haven't performed ANY maintenance on it at all. Every time I see someone with a Whisperlite, it seems like they are always having to make repairs or trying to clean the jets in order to get it going again. I have even let my Coleman sit around with old gas in it for long periods of time (not recommended) with no problems at the next lighting. I do recommend that you oil the pump cup every now and again.
Lighting this stove is easy - just pump and light - no priming required. It takes a minute or two to go from the initial high yellow flame to the tight blue cooking flame as it "self primes". Lighting a Whisperlite is a minor ordeal, sometimes major.
The stove noise is only moderate; not nearly as loud as a Whisperlite.
The integrated windscreen works pretty well. In high winds though you should still use a separate windscreen to save on gas and boil times (use caution if you do this so you do not overheat the gas tank - it should never be hot to the touch).
I own many different backpacking stoves; but would probably keep this if only allowed to own one. It's probably a little heavy for warm weather backpacking but is ideal in the cold where a more robust stove is required.
I would love to see Coleman do a lightweight redesign of this stove and shave some weight off. For instance, Coleman could use the excellent legs on their Exponent Feather 442 stove on the Multi-Fuel and get rid of the plastic legs and "leveling ring", which isn't very useful (I removed the ring from my stove). It's easy to level using other means. The gas tank seems thicker than need be. Coleman could save more weight here by making it to the same specs as a fuel bottle, if regulations permit.
As of this writing, Amazon isn't selling this stove anymore but it is still available at many other retailers.
Another excellent white gas stove is the Optimus Nova. It burns many different fuels without having to reconfigure the generator. A new Nova will cost you well over $100 though. You can get the Coleman for as low as about $55 new, and much less if you are lucky enough to snag one on Ebay.
**Update; November, 2009**
Great to see Amazon selling this stove again. After owning it for 20+ years I finally had to replace the pump cup as a result of it not pumping air into the tank very well. If I would have oiled the cup every now and again like you are supposed to, I'm sure I wouldn't have had to replace it. Another nice thing about this stove is that spare parts are readily available if needed. Also after I wrote the original review; there are now butane/canister type stoves designed for cold weather; I haven't tried them yet, but have heard good things about them. And finally, if you are looking for the Coleman aluminum nesting cook pot for this stove, you will see it occasionally on Ebay. Happy trails.
