There’s a special “winter” gas mix available for gas stoves. How is it different from the usual propane/butane mix and why does it work better in low temperatures? (Does it work better in lower temperatures? :-)
While there seem to be a few different mixtures, key to them all is a lower vapourisation temperature requirement and lower viscosity so they are easier to ignite.
In cold weather, normal fuel may not flow will or may not be able to light as it won't vapourise.
