Butane and propane are excellent fuels to use with your camping stove. Propane works in all temperatures and at any altitude but is the heavier fuel of the two. The weight is noticeable on a hiking trip so keep that in mind when you’re choosing fuels. Butane is a great fuel for specific conditions. The butane canister may have trouble firing at higher altitudes while propane will still work fine. Propane will start to have issues working at altitudes above 10,000 feet. Manufacturers generally recommend you stay below 5000 feet for the stove to work properly. If the temperature gets too cold then butane has a hard time with vaporization and won’t be able to start. Propane typically stops working around -40 degrees Fahrenheit while alcohol will work even below that.
