E. M. Smith, blogging at "Musings from the Chiefio", is using up his cache of emergency supplies prior to a big move. He brings us a long list of emergency supplies that he'd accumulated, and how well they performed after extended storage. It's a very useful "reality check". Here are a few examples.
The gas I’d stored about 1.75 years ago start of the plandemic was smelling just a tiny bit funky, but not “varnish” yet. Started the 1 kW Honda generator and ran one whole evening on it (nominal run time 8 hours, I got about 7 as I had it partially choked to stay running). Figure “one fill per night” if running a TV some lights and a bit more.
White Gas / Coleman Fuel
My “Dual Fuel” single burner stove and dual mantle lantern have been fired up. The stove has been my primary cooking appliance for about a week now ... The lantern was found to have a full tank already. I’d guess about 2 to 3 years ago was the last time I fired it up. It smelled fine and worked fine ... The cooking has taken about 1 cup / day. Maybe a bit less ... I’d plan on about 2 gallons / month for cooking. More if you have a bigger tribe.
Wax / Candles
Wax just keeps forever. It just does. Only thing that can go wrong that I’ve run into in about 40 years of using it as an emergency light source is that candles will melt in the trunk of your car in the heat of summer.
What’s gone first? Fresh milk, butter, yogurt, fresh meats & fish, fresh eggs, cheeses, fresh vegetables & fruits. (Followed more rapidly than expected by canned fruit… something about that syrup ;-) Also cans of “meals in a can” like ravioli and stews. Ritz Crackers, cookies, snacks like jerky and trail mix, and chips all disappear rapidly too. Knorr Sides (in those foils packages for about $1 each) and canned milk get used rapidly too ... In between was the canned meats.
For fuels, what stores easiest, is easiest to use and with fewest issues is Propane, followed by the little Butane cans for the “Asian Stove”. Camping Iso-Butane stoves come next but are harder to cook on, have less control and pots want to fall off, and the fuel costs more ... Alcohol Stoves work well, and easy ... Gasoline / White Gas work well, but storage is more problematic. Not just the flammability issues if it is open or spilled in pouring; but for Gasoline, you get a year, 2 max, and need to rotate it before it goes all varnish on you ... I’m very much of the opinion that a Survivalist Generator of about the size of the Honda 1 kW, but running on Diesel OR Kerosene, would sell to a LOT of folks around the world. I’d pay double the going rate of a gasoline version.
There's much more at the link. Very interesting information, particularly when so many of us are preparing for the hard times that so clearly lie ahead. Highly recommended reading.
