Nevermind

I agree with Stretch above - the cause of the sticking probably isnt the grease, its the muck. De-muck the system and any grease you use will probably be ok.

On the conveyor systems I've seen - if the system was in a warehouse-sized freezer- they replaced the oil (or drained it entirely) with something low-temperature rated. If it bugs you that much, there are greases advertised as being made for low temperatures.

Next year (or later), if it gets this cold, you might be mucked up again enough to stick- not sure that better grease would solve this. I would say that this is the price you pay for not replacing the starter in the first place.

Whenever I've home-rebuilt a starter, I used wheel-bearing grease on the bendix and 'outside' sliding parts - I dont remember this setup ever giving me a problem (but nor did it often get to 0*F outside...except that 240D I drove to Chicago 8 times over a winter install project... and nor did I keep that car for more than 4 years after...)
