i actually just serviced my fork for winter riding; i emailed Manitou's CS and they recommended for colder temps using 3wt Maxima fork oil (instead of the usual 5wt oil). It's what they put in their Mastodon fatbike fork. So far I've ridden it in temps to about -14°C and have found it to work a little better than the 5wt.
