I've got an"old"(green) coleman folding "white gas" stove, Had it for decades; it always fires up.
and a couple of gallons of sealed "coleman fuel" set a side for emergencies. I believe it'll run on unleaded gasoline in an emergency.

You can create alcohol stove out of popcans. Or just put it in an empty tuna can and light it. fuel them with "denatured alcohol"(available in sealed metal pints and quart cans from the paint area of most stores.
