Simmerlite Weight vs. WindPro Weight

Bob, if you do somehow arrange for some of those canisters to get here to CA, put me down for a few.

I don't expect to be driving through Boise until June, so I don't think we can count on any canisters.

–B.G.–

"…my smaller Sigg fuel bottle weighs only 5 oz with the MSR pump in it. full, it weighs 17 oz. that is 12 oz fuel by weight in a container weighing about 3 oz."

One breif correction here. The density of WG is around .72 that of water (fluid ounce, mass.)
12 fluid ounces of fuel will only weigh ~8.64ounce (weight) near as I can guess. WG is not pure octane. It is a combination of lighter burnables that is close. So, this figure may be off in decimal points, depending on your exact mix…it varies from batch to batch. I usually think of 3/4 or .75 as close enough for hand grenades.

5oz + 8.64 = 13.64 Not the 17oz stated above.
A 16oz PET bottle weighs about .75oz, depending on what type (1.1oz Coke bottle, .4oz water bottle.) So, 16 fuid ounces of WG + water bottle weighs very close to 12 ounces.

Don't ya just love the English measurements? Grams and liters are much clearer.

I've totally struck out on finding some Bernzomatic 175g butane/propane canisters. They aren't even listed on Bernzomatic's web site. They just list propane and MAPP gas.

They sound nice, but they may not be available in the US.

There may be other factors at play in addition to the raw BTU/lb of the different fuels, such as how efficiently they burn in the stove. Ignoring priming differences, the easiest comparison I can make is what MSR claims for their new WhisperLite Universal, which combines the fuel capability of the SimmerLite and WindPro II. MSR claims that 1.0 fl oz (volume?) of white gas will boil 1.3L of water, and that 1.0 oz (mass) of isobutane/propane (IsoPro) will boil 1.8L. So the initial comparison of 8 oz isobutane/propane would be equivalent energy-wise to about 11.1 fl oz of white gas. If MSR's claim is for fluid ounce of white gas (not for ounce mass), then accounting for the density of naptha, that 11.1 fl oz would weigh 7.7 oz. So for the same energy (water-boiling capability), the fuel weights would be nearly identical.

Raise your right hand if you have had a "close encounter of the wrong kind" with a white gas stove. I am careful, cautious and experienced-I have used them all my life and I have had several flaming fireball incidents. They never happened while I was car camping-where the hospital was only an hour or 2 away-if you knew how to find it. This always seemed to happen way back in the woods where it would be a death march to get a burned person out. Since I teach classes and take people out on trips I decided to use canister stoves.

Cannisters can be re-cycled. I run mine out of gas and use the Jetboil Crunchit tool to open the valve hole and poke a few holes around around the sides. Now you have turned your cannister into a metal can and it can be recycled that way.
