The blue gas bottle is butane, ok its gas but…it’s crap in freezing weather. The red gas bottle is called propane, it’s also gas, still following??
But the red bottle isn’t really affected by the freezing cold weather. The other stuff (butane) stops working as it freezes up. But….propane is much more money! Lesson? If it’s winter and near freezing or below, propane is the bottle to get! This will then not freeze up and you will be able to use your cooker/fridge etc easily without the worry of frozen gas.
