Yes, if they have it. At least, give them an idea what temperatures it will be subject to. Most any oils will be good in fairly low temperatures, it's when old oils/greases are left in the mechanism that coldweather problems crop up.

I'm thinking that a really thorough CLA where all the old gunk is removed will solve your problem.
