@scott zhp Lubriplate at one time made some low temp white grease that was great down to -40 C/F. I used it in the chain case of my sled back in the day. It actually didn't seem to seperate as much as the regular stuff either. I think what happens to the bowden cables(same as what happens with the door handles) is that the cable lining gets a grove worn into it and then the slightest bit of moisture freezes the cable into the grove.
