This heavily depends on the temp range you are discussing.
Lubrication is the least of your worries at certain temperatures. The engine block and pistons being too cold cause problematic expansion and contraction which can lead to block cracks or permanent engine knock issues from what I've seen. This will eventually lead to needing an engine replacement.
