Also called white gas or camping fuel, you can't beat the Coleman Butane and Propane 1 Gallon Camping Stove Replacement Fuel for camping in the winter or at high altitude. Burns hot even at subzero temperatures. Coleman Fuel is very refined, and burns hotter and cleaner than other liquid fuels. It's relatively inexpensive and not difficult to come by. By carrying the fuel in small refillable fuel bottles, you don't have the disposal considerations you do with empty propane or butane cylinders.
