Cold weather chain lube? My Rock N Roll Gold bike lube seems to get solid or gelatenous when stored on my unheated, but enclosed porch at colder temperatures.  Is a chain lubricated with this product still going to be sufficiently lubricated when riding in freezing (below 0c or 32f) temperatures?  Should I find a different cold weather alternative?
This can be a regional thing, but here in Germany, many are happy with Ballistol applied as aerosol and not changed during the seasons. 

From a material science perspective, its viscosity is very low and has little temeprature dependence. It is also said that it is environmently friendly, to the extend that you can use it on pets, which I never tried as I found chains on my bike much more suitable.
